Astrogator's Logs

As our time and stamina have been consumed by attempts to survive the increasing instability in our world, social media have also shortened our attention span. Things change fast online, and it’s possible that the constant rapid scrollings and headline browsings are making our behavior revert to gatherer-hunter fight-or-flight reflexes.

With the advent of Tumblr and Medium, long entries on WordPress blogs were deemed passé, TLDR. Many bloggers fell silent, went communal, or funneled their content into paywalled Patreons and Substacks. However, the recent implosion of Twitter has made longer writing come somewhat back into fashion — though “longer” usually means the 500 characters allowed on Mastodon, rather than essay-length musings.

In my case, the avalanche of tasks in the last three years as well as an infrastructure-mandated overhaul of my entire website led to mostly silence on my blog in 2021 and 2022. My readers, understandably, wandered away. I also found myself wondering if I still have anything worthwhile to say: I started the blog in 2006, wrote slews of posts on the fleet of subjects that interest me, and I’m now firmly in my third youth. It’s harder to get excited (or annoyed) sufficiently to craft lengthy articles and find fitting accompanying images.

But I missed writing on the blog sorely, just as I missed the small but wonderful community that had grown organically around it and around the constellations of subjects it explored. So I’ve decided to see if we can once again gather around this hearth and share stories until the time comes for the long sleep.

It has been a longish while since I last wrote a post. The madness of US politics and the pandemic hardships, on top of the never-shortening to-do list, temporarily saturated my bandwidth. But that doesn’t mean I’m totally off the swim of cultural pop, as the opinions below demonstrate.

— The Mandalorian has confirmed itself as dedicated fan service with its assiduous mining of archives in classic missing-scene fanfic mode. Yodling/Grogu/whatev remains consistently annoying and my views of the Jedi remain unchanged (in an interesting sidebar about childgathering in Star Wars that has been left to lie fallow so far, Din Djarin himself is revealed to be not just a janissary, but also a member of a extremist splinter cult in his adoptive culture).

That said, Rosario Dawson made a poised and poignant Ahsoka Tano (Anakin’s name trembles on her tongue at one point, reminding us of the Jedi Council’s lethal self-satisfied stupidity); and Katee Sackhoff was a steely, unflappable Bo-Katan Kryze. However, Temuera Morrison’s Boba Fett looks to be phoning his part in, even if we take the character at his full age and hard living. Where’s Julian Arahanga (as fierce as Morrison in Once Were Warriors) when you need him?

— Discovery is also mining its archives (Andorians, Trill symbionts, empaths) while threatening to become full-time therapy cinema; too, I think Saru making Tilly his Number One because she’s not fully qualified and has nebula-sized insecurities is an appalling decision. The series creators appear to be advancing the tenet that it’s good to have a wobbly high-ranking officer (“No elitist experts!”) plus it’ll be convenient when disobedience suddenly becomes the right stance for a plot twist. It also brings up, yet again, the fact that Starfleet is in fact military, despite its pious mouthings about scientific priorities.

Equally against not just common sense but also principle is the Vulcan president’s unilateral decision to covertly hand over potentially dangerous data to a powerful entity that may not be benign, despite the stated cogent reasons—as well as the transparently self-interested wishes—of all the motley groups that make up this universe’s Vulcan-with-Romulans. Parenthetically, it’s interesting that (with the partial exception of Enterprise) no Star Trek series has managed to make Vulcan just going about its business arresting on its own, resorting to variations of blowing it up instead—perhaps the “Follow your feeeeelings!!” crowd’s ultimate revenge.

The transportation of the Qowat Milat sisterhood of lost causes from Picard into Discovery adds a potentially bracing condiment to the stew, but Gabrielle’s initial behavior towards her daughter is inexplicable unless you chalk it up to convert zeal; likewise, Michael’s avoidance of finding out how her little brother fared once she literally left him behind is equally against character. At least David Ajala (Cleveland Booker, the worthy inheritor of the Book moniker from Firefly/Serenity and a far better partner to Michael than Ash/Voq) remains balm on both brain and eyes, just as Ethan Peck (younger Spock) and Anson Mount (Captain Pike) did in the previous season.

Both The Mandalorian and Discovery try to show what happens after an empire has fractured into tribal splinters. The Mandalorian is better at capturing the anomie, opportunism and potential of this configuration, whereas Discovery dangles reconstruction optimism in typical Star Trek fashion. Of course, the franchise hedges its bets by having its concurrent Picard outing hard at work to deconstruct this hopeful mirage. The combined view from Discovery and Picard suggests that the Federation was/will be as good an overlord as the Empire. At least Discovery is no longer summarily killing its mother figures, while The Mandalorian hews to the Lucas diktat of bringing kids up without them. On the third hand, I’d hate to see Ahsoka Tano abandon her own quests to help raise Gluglu, despite fetching Madonna-and-Child poses in that episode.

— I recently finished two science fiction novels that looked extremely promising at the start but fizzled out spectacularly midstream: The New Wilderness by Diane Cook and Goldilocks by Laura Lam.

Wilderness is an apocalyptic limited-knowledge-POV diptych that’s admittedly atmospheric but totally lacks character depth (everyone remains a cipher) and context underpinnings. Goldilocks starts with the launch of a fascinating unsanctioned mission (with interesting correspondences to the Mercury 13), only to then spring all the hoary tropes on record: demonic powermongering crone, unplanned pregnancy as an unexpected boon, deus ex machina global rescue. Where are good editors when you need them?

— Last but not least, I saw Ammonite, a film purporting to “freshen up” the story of Mary Anning, one of the intrepid explorers who changed science despite the strictures laid upon her by Victorian mores. Beyond being a second-class human (aka a woman), Anning was also working-class and self-educated, additional stones in an already bulging bucket of handicaps. Cuvier accused Anning of fraud, since someone like her could never possibly have achieved what she did. And of course the conclusions forced by her findings (she was Darwin’s contemporary) went directly against the dictates of what was then state-sanctioned religion.

It comes as no surprise that the “freshening up” in Ammonite is a no-holds-barred sexual bonfire between Mary Anning and Charlotte Murchison, respectively embodied by Kate Winslet and Saoirse Ronan—both outstanding at portraying complex characters. In real life, Anning and Murchison hunted fossils together and became close friends; and of course Victorian-era close friendships between women could be anything from the equivalent of the Han laotong to full-blown love affairs and Boston marriages.

The chemistry between the two performers is incandescent, the sex scenes undeniably hot. And Winslet, in particular, excels at presenting Anning as a formidable presence who won’t be bent into performing the traditional feminine appeasements even for love. However, the focus on the love affair detracts from seeing Anning at her work. The glimpses we get are thrilling, and we crave more. Additionally, Murchison was not the wilting, lisping princess of this film: she was a geologist who traveled all over the world pursuing her interest, and it’s unlikely she had the brittle Betty Boop mannerisms that Ronan adopted for this incarnation.

If you want a truly insightful, absorbing view of Anning that does full justice to her vocation, read Tracy Chevalier’s Remarkable Creatures. Chevalier chose a different counterpoint for Anning: Elizabeth Philpot, who’s reduced to a doleful spurned lover in Ammonite but was a far more dynamic figure in real life (inter alia she was Anning’s mentor). Women who broke molds deserve happiness and hot sex; but they also deserve full embrace—and illumination—of their creative fires.

“Nen lókdwenzish, Michael”: Sister-Brother Love in Science Fiction

“He turns the clouds into a horse, the stars into a bridle,
and with the moon as company he goes to bring her back.”
— The Dead Brother’s Song, 9th century CE
(perhaps the oldest surviving Hellenic folksong)

There’s a deeply-rooted biological reason why nearly all unforgettable stories are family sagas, whether they unfold on the plains of Troy or the spice beds of Arrakis: humans are not solitaries; we’re embedded in our kin groups. That, in turn, colors all aspects of our behavior. Whatever our technological level, we remain keenly interested in personal connections, as central throughout civilization as they were in the bands of ~100 members that comprised the initial gatherer-hunter tribes (and still do for our first cousins, the bonobos and chimpanzees).

Stories from all cultures explore the full gamut of family interactions; but mainstream and genre literature, especially the dominant Anglophone incarnations, heavily pluck only a few strings of that versatile instrument. Mainstream tends to foreground mating interactions – the inherent dilemmas between blood and chosen kin, between old obligations and new loyalties. Fantasy has walked in the steps of its predecessor, folklore, of which more anon. Science fiction (SF), on the other hand, notoriously fearful of “chick-lit” or “romance” cooties, twangs primarily on father-son conflict, with brother rivalry a distant second. Mothers are invariably dead in SF and fantasy, unless they surface as either evil stepmothers for daughters or impediments to independence for sons. The vast majority of SF has let one particular chord lie mostly fallow: sister-brother love.

Myths and folktales brim with sister-brother stories. Many pantheons have sibling pairs down several generations as their base: Gaia/Ouranos to Hera/Zeus, Nut/Geb to Isis/Osiris, Izanami/Izanagi, Yemanja/Aganju. The bond is also a major engine in literature: Electra, Ifighenia and Orestes; Antigone and her two feuding-till-death brothers; Alexander’s sister Thessalonike, ruler of Macedon after his death, said to have become inadvertently immortal and to have mourned him forever after as a storm-wielding mermaid; the Akritiká folksongs, starting with Konstantís and Aretí in The Dead Brother’s Song; the brothers in the Grimm tales turned to harts, ravens, swans protected (often at staggering cost) by their sisters; the Völsungs Siegmund and Signy aka Sieglinde, Kullervo and his nameless sister (and the Tolkien clones, Túrin and Niënor)…which highlights a reason why Anglophone speculative literature, far more priggish than its predecessors, avoids this chord except in the gritty-grotty dark fantasy cave where Cersei and Jaime Lannister dwell.

The not-too-hidden shoal, of course, is incest. Whereas parent/child incest has steep in-built power differentials, sibling incest is on almost-level ground – and several cultures have practised sibling mating, especially among groups where either “purity” of descent or retaining family property was paramount. Physical or cultural isolation also factored into this. Before the advent of DNA analysis, unless men kept punitive vigil over women, the paternity of offspring could never be incontrovertibly known, whereas children of maternal relatives were without a doubt genetically close to their mothers’ male kin. Hence, sibling matings – or, in much of the world, cousin marriages. A more benign alternative to obsessive patroling of female reproduction were the systems in which a sister’s children were heirs of her brother’s property and/or status (Fili in the film version of The Hobbit is an explicit example of this).

However, given the overall habits of humanity, there is a second, less obvious shoal. In most of the list above, even when brothers love their sisters, it’s invariably the sisters who must abjure their life, happiness or vocation to further their brothers’ objectives. Both Electra and Ifigheneia break all kinds of taboos and vows for Orestes’ sake; Antigone’s decision that she’s duty-bound to bury Polyneikes makes her forfeit her life when she’s at the cusp of a love match consummation; Leia ends up untrained in her Force potential and very much an adjunct to Luke and the shabby Jedi initiatives (the Mary Poppins act in The Last Jedi is an almost-contemptuous afterthought as is Anakin/Vader’s reaction when he becomes belatedly aware of her existence in Return of the Jedi); likewise, Alia Atreides is an instrument of Paul’s messianic goals throughout the Dune saga.

Fantasy has told tales of sisters shaping their lives around brothers, from Éowyn to Jane Yolen’s “Brother Hart”. Science fiction has mostly elected to slide by such bonds or keep them largely schematic: Leia and Luke don’t interact meaningfully once it’s established they are twins, and Leia’s great moment happens before she discovers she has a brother (Luke goes on to change the fate of the galaxy before he peters out into a damp squib). That said, two major exceptions in SF come to mind that show not only a sister and brother devoted to each other, but also a scenario in which the sister does not sacrifice herself in some way for her brother: River and Simon Tam in Firefly/Serenity; and Michael Burnham and Spock in Star Trek: Disovery.

The River/Simon arc is in some ways strongly reminiscent of The Dead Brother’s Song: Kostantís promised his mother that he’ll bring his sister home, and not even death will deflect him from his purpose. Simon, too, is committed to retrieving his preternaturally talented sister, at the cost of his family fortune and cherished vocation — though he, at least, is spared the ultimate sacrifice. It’s an incidental reward that Simon’s rescue of River uncovers the immoral experimentations of the Alliance. The siblings are lucky enough to find a hearth with the lovesome if unruly Serenity crew, where River has a hope of healing and both can forge meaningful lives.

Michael/Spock is a sentimentalized yet touching variation on Electra and Orestes. The Powers that Be mapped Michael’s character development primitively (Season 1: Logiiic! Season 2: Emotionnn!!), though it gradually emerges that she’s named after the warrior archangel for valid reasons. She also suffers from a surfeit of parents, but I’m happy that she’s granted not one but two mothers who do a whole lot more with their lives than mothering, and even happier that she evolves into a formidable mover and shaker in her own right who’s allowed a lover (standard bumps are put in that path, but at least they’re not the career-versus-family cliché). Even rarer is that the series also lets her love her little brother and be loved by him without faux-edgy penalties. Of all the interaction arcs in Star Trek – and beyond – that’s the least trodden.

[Parenthesis 1: Spock’s total silence on the topic of a sister was a major roadblock for original-universe Star Trek fans. By the end of season 2, Discovery managed to have its cake and eat it, too: remain canon by virtue of industrious retrofitting, but also allow AU scenarios by catapulting Discovery to where none has gone before. The crew that stayed behind is as interesting and fresh as the one that went ahead…and by adding Section 31 goings-on we face the prospect of at least three series, with potentially huge lunchbox/paraphernalia lucre.]

Spock’s inner conflicts, echoed by Michael’s, remain compelling and poignant. In Discovery he reconciles with his adopted sister after a long estrangement and they help each other in crucial ways (to say nothing of the universe’s long-term future). Of course, this is a Hollywood series and a franchise captive to both tradition and profit. So the derring-do is arbitrarily ratcheted for unearned drama. Nevertheless, in a manner that’s unusually quiet for Hollywood, brother and sister enable each other to fulfill their immense potential. The ending is a trailblazer on several levels: their adieu is stark and in minor key; it also shows Spock – a potent cultural icon of long standing – first willing to follow his sister into the unknown, then acknowledging her as his lodestar and role model. Mind-boggling that this happened only in 2019, but at least it happened.

[Parenthesis 2: What made a crucial difference, to me at least, was Ethan Peck’s take on Spock. It’s a welcome original angle (as much as that’s possible with the character). I vastly prefer his interpretation to Zachary Quinto’s, though some of this is leakage: I detest the reboot, which has totally abandoned Star Trek’s exploring mindset for Fast-n-Furious-in-Spaaace grinding noises.]

Sister-brother love is a hybrid like Spock, like Michael – poised between that of mates and parents/offspring, between agape and eros. It shares some of the frisson of the former, the deep hooks into the solar plexus of the latter. The next cycle of Discovery may be interesting – and, who knows, that of Enterprise as well if the producers choose parallel developments (those lunchboxes…). But it won’t have Amanda Grayson’s children of the heart urging each other to ever greater achievement. Nor is it likely that Whedon will add to the Serenity/Firefly ‘Verse. Everything must come to an end. But the gatherer-hunter part of me wishes I could see more of Michael with Spock, River with Simon…in their full flowering.

Postscript: I predict that in future seasons Discovery will be allowed to do the occasional deus-ex-machina foray into the “regular” space of Enterprise, if only for Michael to stock up on hugs with Spock, her adoptive parents & Tyler.

Cat Rambo graciously invited me to participate in a StoryBundle with the acclaimed science fiction anthology To Shape the Dark, focused on women scientists doing science not-as-usual.

The storybundle, curated by Cat, has the evocative title/theme Feminist Futures and runs till March 29. In its wake, Cat did 10-minute interviews of several of the participants; and as a result, you can see me dreaming and opining on YouTube (personal note: for those curious about how I look/sound, this is your chance).

To Shape the Dark, the younger sibling of The Other Half of the Sky, focusing on women scientists doing science not-as-usual, has become as widely acclaimed as its illustrious predecessor: among other recognitions, it won a starred review in Publishers Weekly, and two of its stories have been selected by Gardner Dozois for his Year’s Best SF 2016 (Melissa Scott’s “Firstborn, Lastborn” and Shariann Lewitt’s “Fieldwork”).

To deepen the readers’ enjoyment of the antho stories, I asked the contributing authors to share thoughts about their works. Below are some of their musings. More musings will appear after the new year.

Constance Cooper: Carnivores of Can’t-Go-Home

I decided to write about a botanical survey after hearing my husband’s stories of childhood trips with his dad the botany professor, driving across the country with bundles of specimens tied to the roof of the car. What, I wondered, would it be like to do that on an alien planet? For me, it was a short step from there to giant carnivorous plants and a murder mystery.

On a deeper level, I tried to imagine how it would feel to grow up knowing you were a stranger on your planet—not part of the fossil record, not related to any local species, separated from the animals and plants that have been part of human culture for millennia. And what if the humans weren’t there by choice? How would that affect people’s attitudes toward their world? My botanist characters are among those who’ve embraced their new home. They find their work so involving that they can’t stand to leave it–even to take a shower after getting slimed by an enormous pitcher plant.

M. Fenn: Chlorophyll Is Thicker than Water

My story “Chlorophyll Is Thicker than Water” got its start with a suggestion from my alpha reader and husband Roy, who wanted me to write a tale about an old woman who was known as a plant wizard in her community, but there was more to her knowledge than anyone suspected. My first thought was witchcraft, but doing some research into the science of plant intelligence inspired me to make my characters be scientists conducting their own research. Choosing to make these women Japanese-Americans who had been interred during World War II came about because of my reading about George Takei’s play Allegiance. What started as a minor point of back story eventually manifested into strong motivation for my characters.

Also, I love writing about old women. They just don’t have time for anyone’s silliness. While Susan and Hina bear little if any resemblance to the witches in Terry Pratchett’s Discworld books, Granny Weatherwax and Gytha Ogg were certain influences in the creation of my own powerful old women. A point of interest that some might find amusing: while all the human characters are fictional and not based on any living person that I know, the parrot who lives at Whitman’s Feed Store in North Bennington, Vermont, is very real, although not named Tony.

C. W. Johnson: The Age of Discovery

I have been writing a sequence of stories revolving around a particular technology, the Casimir pump (which is not real, but the Casimir effect is), and had vaguely thought of a story line involving some of the first applications. I wanted it to be a story about the love of discovery, and wanting to invert the commonplace trope of the heroic lone inventor, I wanted to place it in the context of heavily bureaucratized research. I needed my protagonist to have a foil, and I realized the best additional context to the love of discovery is the discovery of love. From these pieces I wove, with many fits and false starts, my plot.

Jacqueline Koyanagi: Sensorium

The central concept for Sensorium is that of communication across umwelts. If it is a fundamentally unique cognitive experience to be a particular species, then language alone falls short as a vehicle for cross-species communication. I wanted to briefly explore what might happen when those cognitive barriers are broken down technologically–particularly to the people who submit to a neural connection that dissolves the stark delineation of “the individual” that we are accustomed to. What does it mean for a mind if awareness expands beyond its natal umwelt? What changes occur when previously inconceivable sensory experiences are now accessible? What, then, does it mean to be a person? These are the questions that fueled Sensorium and the attendant books-in-progress.

Susan Lanigan: Ward 7

When I was approached by Athena to contribute to her new volume, To Shape The Dark, I was very excited but also a bit anxious. It had been a while since I had written short fiction that was longer than 1,000 words and I knew it would be necessary to construct a small universe in a short space of time. Also I tend to adhere to “hard” sci-fi rather than space opera, so I tend to stick to the near future rather than its more distant counterpart, just as I stick to the nearer past when writing as a historical novelist. Working with Athena was a pleasure as she proved to be a diligent and sensitive editor and I hope to repeat the experience again sometime.

Shariann Lewitt: Fieldwork

The moment I read the parameters about stories for TO SHAPE THE DARK, I knew I had to write about science that takes place in the field.  Most people think scientists wear white coats and work in climate controlled labs, with a rest room down the hall and a coffee bar down the street.  When I studied Evolutionary Biology as an undergrad, I learned about fieldwork the hard way, on a dig.  While I realized I definitely preferred climate control, rest rooms and coffee bars (and ended up in computational biology), I have always had the greatest respect for those who go out into the field and I knew I had to write a story that highlighted a way that science is really done–and that rarely comes to mind.  I had also just finished reading a number of articles on Europa, and a friend who works for NASA’s climate research group was posting pictures from his mission to Antarctica to drill ice cores.

Those things knocked around together in my head and out came Anna Taylor.  Irene came from a more complex and personal place, but also from a desire to turn around the SF trope on the “genius kid who saves the world.”  Because Irina is that kid–but she has to suffer the consequences as well, and later face her own very deep fears because she understands what drives Anna.  This story is immensely personal for me, both from a family perspective, and from my relationship to work I’ve done in science as well.

Today is the day!  Spread the word, To Shape the Dark is spreading its wings. Focusing on women scientists doing science not-as-usual, the anthology is sister to The Other Half of the Sky, which won unprecedented accolades.  This family of feral astrogators may eventually have a third member — keep frequencies open!

The book, both print and digital, is available on all major online venues (Amazon, B&N, etc) but Candlemark combines the print version with a DRM-free bundle. More direct sales also make it likelier that we’ll break even. Relevant sites:

Analog SF said of To Shape the Dark: “…these stories make the reader think. // They challenge us to question some cherished conventions of the field… // If you like well-told, intelligent science fiction that respects the search for knowledge, you can’t afford to miss this one.”

As I say in the introduction, “Scientists are humanity’s astrogators: they never go into the suspended animation cocoons but stay at the starship observation posts, watching the great galaxy wheels slowly turn while they attend to the hydroponics. To Shape the Dark is part of that vigil.”

Music: End of “Love” theme from Joss Whedon’s Serenity (composer, David Newman)

Early this week, venture capitalist Yuri Milner (backed by glittering names that included Stephen Hawking, Ann Druyan, Mae Jemison and Mark Zuckerberg) announced the next step of his Breakthrough plan. Part 1 is Listen – equivalent to passive SETI efforts; Part 2 is Starshot, a mission to reach Alpha Centauri within twenty years by using miniaturized probes. Such a rapid journey is theoretically possible if the probes are equipped with tiny photon sails and accelerated to a percentage of lightspeed by ground or orbiting lasers.

All of the technology needed for Starshot has passed proof of principle, though none of the specific components is actually at hand. The concept itself has enough original aspects – and enough advantages – that it could well succeed: sending armadas of small-cross-section vehicles dilutes the risks and increases the collective chances of reaching the destination. The mission length is just short enough to sustain interest (though people tend not to mention that it will take several more years for any information gleaned by the probes to get back to us — and that the Alpha Centauri three-star system has no confirmed planets). It’s not burdened by the prohibitive demands of slow ships to Alpha-Cen, with or without live cargo. And just starting the engineering of the Starshot components will lead to a spate of innovations, whether the mission is undertaken or not.

Starshot, with its emphasis on new research on miniaturization, laser technology and materials science, underlines the almost complete lack of equivalent biological research that might make larger, slower starships possible – from self-sufficient ecological systems to ways of keeping a crew safe and sane during long star travels. Astrobiology has confined itself almost exclusively (though with some justification) to extremophilic bacteria and nobody is trying to untangle bear-style hibernation, to give but one example. The sole non-bacterial/fungal critters that seem to have engaged the interest of astrobiologists are tiny invertebrates with the formal name of tardigrades (= slow walkers).

The popular monikers of tardigrades are water bears or moss piglets, but they resemble nothing as much as eight-legged micro-manatees, including their habit of placid munching (though they have bear-shaped fangs and claws and some are cannibals). They’ve become media darlings by dint of both perceived cuteness and grace under pressure. Their average size is that of a sesame seed (1-2 mm) and, like mites, they’re found everywhere – from deep sea trenches to the slopes of the Himalayas, from the equator to the poles.

Their anatomy, habits and life cycle are unremarkable, except for their record endurance of extremes of temperature, pressure (both deep-sea high and vacuum-level low), gravity, dehydration, radiation, toxins. They accomplish this by rolling into a compact configuration known as a tun (barrel) and decreasing their water content to 1% of the normal. Just as arctic fish use glycol to keep their structures intact in freezing water, so do water bears, though they deploy another type of sugar (trehalose). Several other invertebrates can enter and exit cryptobiosis – rotifers, brine shrimp, nematodes – but water bears are the only organisms known so far to be successful at all types of it.

That said, media fail to convey the fact that this endurance is statistical: the longer and harsher the conditions, the less likely the survival of water bears – or their eggs, especially at early embryo stages. So one take-home lesson here is that we can shrug at the percentage of tuns that revive successfully, because they’re not fellow humans or even loved pets; they’re not losses that cut us to the quick. It’s also no surprise that people tried to pin the water bears’ abilities to unique genes or gene networks, whereby the tale turns to the dangers of both reductionism and love of magic bullets.

Recently, two groups published the genome sequence of a tardigrade species. One of the two reports, ahead of the other by a few days, got the lion’s share of the press – not only because it was first, but also because it made the flashy announcement that tardigrades are as sturdy as they are because ~17% of their genes come from horizontal transfer. The authors of this study hypothesized that such an influx of foreign DNA is possible when the water bears reconstitute their chromosomes during revival from tun status, at which point they’re leaky across scales. Of course, one prediction of this hypothesis is that tardigrades should have undergone incredibly rapid and divergent evolution, which is very visibly not the case (I fully expect a cult theory of tardigrades as single-point earth life ancestors to spring up as a result of this blog post).

People who know how genomes, organisms and evolution work shook their heads at this announcement and waited for the other shoe to drop. It promptly did with the close-following second sequencing study, which demonstrated that horizontal transfer in tardigrades does not exceed the average 2-3% found in all organisms, and that the results of the earlier study came from contamination of the tardigrade genomic material with DNA from bacteria in the water bears. To be fair, it’s incredibly hard to avoid such contamination, especially with something of water bear size, though there are ways of detecting and correcting it after the fact. However, separating wheat from chaff requires long, painstaking work – and in these days of dwindling-to-nothing funds for basic research, being first is at a premium.

Learning how tardigrades go through literally killing regimes will teach us much about basics, and may show the way to useful applications. But I suspect that most of that knowledge won’t be portable to large, slow-metabolizing mammals like us. What will undoubtedly be of direct use is deciphering the mechanisms behind bear hibernation. Results from such a study will not only be applicable to human spacefaring, but will also help revive patients from long comas and serious traumas with less muscle waste and/or irreversible brain and other organ damage.

Like much research nominally focused on space, investigation of other non-bacterial terrestrial biologies may not only enable us to travel into the beguiling star-studded darkness beyond our friendly base, but may also improve our life here and now. If/when we venture past our gravity well, it’s certain that the imperturbable water bears will be on board with us. And despite stringent precautions against contamination, I wonder if the Voyager craft are carrying tiny sleeping tuns on the winds between the stars.

From the first moment humans looked at the sky, their eyes — with or without aids — could see five wanderers against the celestial backdrop: Mercury, fleetingly visible outside the Sun’s glare; Venus, so bright it can cast a shadow (Eosphóros at dawn, Phósphoros at dusk); Mars, its brick-reddish hue apparent even at aphelion; Jupiter, second to Venus in brightness; and Saturn, about as dim as Mercury – though someone with exceptional vision might just discern the slightly elongated shape that would later prove to be its rings.

And there the count of the solar family remained until the late 18th century, when telescopes and the mathematics of trajectories got sophisticated enough to enable astronomers to make and test predictions. At that point, the Herschel siblings established that Uranus was not a star but the planet next out from Saturn. A little less than a century later, Le Verrier noticed the “tugs” at Uranus’ orbit. Based on these, he predicted, then visually found, Neptune. But Neptune’s orbit showed irregularities also, plus its mass did not totally account for the Uranian perturbations either.

So the search started for Planet X (pedantically speaking it should have been IX, but X is the standard denotation for an unknown). And that’s when things stopped being simple.

The next iteration of the methods that had added Uranus and Nepture to the solar herd yielded Pluto. The problem with Pluto, which led to its eventual dethronement as a planet, is that there are many Pluto-sized planetesimals in the asteroid and Kuiper belts and in the Oort cloud — several with accompanying moons, like Pluto has Charon. Amusingly, many carry names of female gods or heroes and/or from mythologies beyond the Roman in a belated effort to change the heavily skewed naming ratio of the major planets.

So either Pluto of tiny mass and eccentric orbit did not deserve the distinction of being called a planet – or Vesta, Ceres, Eris, Sedna et al had to be included in the roster (side note for SFF doofs like me: Eris, named after the goddess of discord, was originally called Xena; its attendant moon is officially called Dysnomia, the Greek term for Lawless… as in Lucy Lawless, who played Xena the Warrior Princess; personally, I think they should have stuck with Xena and Gabrielle, but I’ll admit to some lack of objectivity). To the relief of both astronomers and astrologers, scientists drew the line at entities so small that, even if they’ve attained roundness, don’t have the oomph to either fling or pull planetesimals in their vicinity.

Yet the idea of a giant planet or brown dwarf hiding in the outer darkness has too strong a hold on our imagination. Starting with paleontologists Raup and Sepkoski, scientists proposed such a distant lurker whose orbital movement might have caused impact events resulting in the mass extinctions that occur on Earth about every 27 million years. For obvious reasons, they called this hypothetical planet Nemesis (Retribution). The long, systematic hunts for Nemesis yielded nothing except the conclusion that nothing larger than Saturn is rolling for several thousand AUs beyond Neptune. That’s disappointing, but there’s a large size gap between Saturn and Pluto where a respectably sized outcast can still dwell.

The productive game of checking for orbit irregularities and sweeping/herding behavior got applied again recently, when several astronomers (first Sheppard and Trujillo, then Batygin and Brown – all Kuiper aficionados and decisive influences in demoting Pluto) noticed a pattern in six “sednoids” – largish denizens of the Kuiper belt. Their behavior indicated that they had been disturbed by something large. So Brown and his collaborators fed the pertinent details to a simulator… and out popped the prediction of a planet at least 10 times as massive as Earth (i. e. Neptune-sized) with a highly eccentric, off-center orbit – a victim and survivor of ejection from the inner regions of the solar system during the early stages of its formation.

Brown was meticulous in exploring and evaluating all other possible explanations of the planetesimal disturbance pattern, just as Boyajian and her co-authors did with the anomalous brightness dips of KIC 8462852. The hypothesis of a Neptune-sized planet at that region passes the Occam’s razor criterion. But only one thing will make Planet Nine move from hypothetical to real: seeing it with a telescope. So some astronomers have been sweeping the starry dark with high-powered wide-field telescopes, while others have been comparing time-lapse photos to see if a bright needle has moved relative to the rest of the haystack.

If Planet Nine proves to be real, it will give us important insights into the workings of our solar system and will help us judge how unusual it is compared to other systems found by the industrious Kepler telescope. And if its existence is confirmed, the arguments about its specific details will pale in comparison with those over what to name it. Some want it called Jehosaphat; others, Janus. But I propose Tiamat, the exiled Great Goddess of the Deep.

This morning, an hour before dawn, I put a coat over my sleeping togs and went outside.

In the west, the Hunter and his Hounds were accompanying the near-full moon, Sirius as bright as a mithril coin. In the east, where the black was starting to turn to indigo, was the jagged procession of the three bright candles – silvery Venus, golden Jupiter, bronze Mars.

It never ceases to grip me, this beauty that floods my breastbone with longing.

Part of this yearning is our eternal quest for companionship, recently sharpened by the report of odd light dips of the F-type star KIC 8462852 — nicknamed Tabby in honor of Tabetha Boyajian, the lead author of the study and the head of the crowdsourced Planet Hunters project that sifts through the Kepler Space Telescope findings.

About 1,500 light years away in the direction of the Cygnus constellation, the star is too old and stable to have a dust accretion disk. The dips could be the result of a cometary collision or gravity darkening from rotational flattening… but for the first time the SETI community uttered the words “Dyson swarm” with the slight, slight likelihood they might be more than fond wishes.

We have to be dispassionate and rigorous in this, as in all other scientific explorations – especially ones that we’re vested in. After all, pulsars were first designated LGM (Little Green Men) before the non-sentient basis of their regular pulsing was deciphered. But now there’s at least one reputable paper out that outlines how to distinguish megastructures from natural planetary bodies.

If there was a civilization around Tabby that was advanced enough to create sunlight-capturing structures, what we see may no longer exist or may have evolved into something “rich and strange”. More time on different types of telescopes may resolve this. In the end, the yearning will remain; we’re wired for wonder. There’s a reason (beyond the fact that I sorely miss my own beloved father – ally and confidante since toddlerhood) why the alien in the guise of Ted Arroway caressing Ellie’s cheek in Contact brings tears to my eyes.

I’m delighted to once again host my friend Calvin Johnson, who earlier gave us insights on Galactica/Caprica, Harry Potter, The Game of Thrones, Star Trek: Into Darkness, Interstellar, and the works of Hanya Yanagihara, Ken Liu and Liu Cixin.

Science fiction is full of ideas. But the ideas in science fiction seldom have the depth and rigor of ideas in science, or in philosophy, or politics and ethics. The reason I say this is: in fiction, the game is rigged. The debates are one-sided. The author gets the first, middle, and last word.

This is not to say that the ideas in science fiction cannot capture the imagination. Indeed many classic SF stories that have inspired careers or even presaged the future. But not all have. The ideas in SF are not fully developed theories or philosophies, but more like Edison’s famous ten thousand attempts at making electric light: we remember the one that worked and forget, mostly, the ten thousand that didn’t.

But the ones that work, either through vivid imagery or asking difficult questions or getting lucky and “predicting” the future, stay with us. Once in a great while, there is even a story that causes me to rethink my opposition to describing science fiction as a “literature of ideas.”

Such as Kim Stanley Robinson’s latest novel, Aurora.

#

Let me explore the concept of fiction as being rigged. Science fiction typically assumes some future technology, whether it be interstellar travel or time travel or life extension, is possible. It is only after such an assumption that we arrive at the “idea” in science fiction: a fable about unintended consequences–step on a butterfly in the Cretaceous, change all of history–or to ask, a la James Blish, Who does this hurt?

But these moral fables–for that is what they really are–gloss over the assumption of a technology. Many enthusiasts believe in a kind of technological manifest destiny: we can achieve any technology, if only we are smart enough, or put enough effort into it, or let market forces achieve it.

In support of such a view the Manhattan Project, the Apollo Project, and Moore’s Law are often cited. Such citations often ignore the fact that those successes were a matter of scaling known engineering. The basic physics of fission reactions, of space flight, and of transistors were known long before those projects and observations began.

Here’s the problem: one should not conclude, by way of analogy, that any technological goal can be achieved by sheer perspiration. The easiest and most obvious example is in human health. By a wide margin, the most crucial leaps to better health have been good sewage management and vaccines, followed by antibiotics. But after that it becomes much harder. If market forces alone were enough, we would have conquered cancer long ago, but while some cancers are curable, many others we can at best slow down. (This, of course, is because “cancer” does not have a single etiology.) There are start-up firms devoted to engineered immortality, but none have added a single day to human life spans.

In short, just because you can imagine it doesn’t mean it is actually possible. I’m still surprised how resistant people are to this basic principle.

#

Of course, interstellar flight might seem like a straightforward if ambitious scaling-up of the Apollo program. But Tau Ceti, one of the closest singlet G-class stars (i.e., like our sun), known to have at least five planets, is almost 100 billion times farther away than our moon. That’s a lot of scaling; by comparison, Moore’s law from 1971 to today has seen a mere one million times increase in the number of transistors on a chip.

And Moore’s law has a cost. As transistors shrink, the chip foundries become increasingly complex, costing over US$1 billion to build, and using prodigious amounts of caustic chemicals. The market pressures so far have masked these costs, but even so the market for personal computers has saturated and it is the market for phones which has largely driven further developments. But now with billions of phones across the globe that market too is becoming saturated. We’ll see replacements, of course, but that is linear; the pressure for geometric growth described for Moore’s law is diminishing.

And in a way, this is the story that Robinson tells in Aurora.

Some minor spoilers ahead; I’ll keep them to a minimum, but I will outline some key plot points. If you want me to cut to the chase, it’s this: in my opinion, Aurora is the best hard science fiction novel since Benford’s Timescape, and Robinson achieves this by blowing up the usual assumptions, and jumping up and down on them until they are ground into tiny bits.

Aurora is about interstellar travel. A ship, one of many, is sent at one-tenth of the speed of light to Tau Ceti. This journey takes almost two centuries, and so generations are born, live, and die aboard the ship.

In Robinson’s novel, interstellar travel is possible, but costly. First and foremost, keeping a closed ecosystem running is not easy. Robinson has hinted at these concerns in previous novels, in Icehenge and his Mars trilogy, and here he spells them out in detail, thinking out how a generation ship would work (and not work) to a degree not achieved before. The specific biochemistry is a little beyond me, but he is married to an environmental chemist and, most importantly, the principle is sound. Managing trace elements such as bromine isn’t easy: too little can have dire consequences, but too much and you have toxic effects. The designers of the starship had to try to predict how the ecosystem would behave over centuries. Robinson assumes the designers did a pretty good job, but even in a pretty good job a few miscalculations or oversights can grow over time.

Just as big a source of problems as technology is politics. Robinson’s politics lean to the communitarian and the ship’s governance reflects this, but he recognizes that every polity can fracture and every system of governances privileges some over others. In this he echoes LeGuin’s The Dispossessed, a novel I first read many years ago in a class Robinson taught at UC Davis, and which is also set in the Tau Ceti system. And as in Robinson’s Mars trilogy, when society is stressed, some people respond badly, even violently.

The politics back home, i.e., on Earth, also shifts. People lose interest in interstellar travel, which soaks up enormous resources, leaving the crew of the ship to their own devices when things go awry.

Most SF novels assume that Things Work Out in the end. A crisis convenient for a thrilling plot pops up, but Our Heroes/ines figure out it in the nick of time, and humans triumph over the odds. This future version of Manifest Destiny has been here since the pulps and never really gone away.

Robinson attacks this idea, in detail and in depth. The technology goes wrong, and there is no magical fix, and people die. (Not always; there are some spectacular saves.) The politics goes really wrong, and more people die.

Moreover, Robinson suggests that Manifest Destiny breaks apart upon the rocks of the Fermi paradox, i.e., if there is intelligent life out there, why haven’t we heard from it? Recently I wrote of the Chinese author Cixin Liu’s solution to the Fermi paradox, a dark and paranoid vision.

Robinson’s solution to the Fermi paradox is more measured and frankly more believeable than Liu’s. In most science fiction novels people on alien worlds can easily breathe the air and eat the native organisms with no ill effect. This has always bothered me, because, for example, humans actually can only tolerate a fairly narrow range of atmospheric mixtures; and as for food, we’ve had to co-evolve to digest plant and animal tissues.

Robinson suggests that most planets are either sterile, and would require centuries or millenia of terraforming–in stark contrast to the decades he unrealistically postulated in his Mars trilogy– or the established life would be so biochemically hostile at a fundamental level that humans could not survive. The latter is of course speculative, but speculation is the game in science fiction.

The universe is full of life in Robinson’s vision, only that life is each trapped on its planet of origin. We can’t conquer distant stars; the costs are too great.

#

Aurora is not a perfect novel. Like most hard SF novels, it is plot and exposition heavy. Only three characters are fully realized, and one of those is the ship’s artificial intelligence. The bulk of the prose is plain and to-the-point, which Robinson cleverly covers by having the ship itself be the narrator. Only in the opening and closing sections, not narrated by the ship, does the prose sing and does Robinson use his literary skills fully.

But few novels in my reading have examined the technology and the difficulties therein in as much detail, acknowledging that science and people are always flawed and limited. I seldom say this, but Robinson’s novel is truly an “instant classic” of SF, and the hardest of hard SF at that. The year 2015 isn’t over, but Aurora should be a shoo-in for major award nominations. Not only that, it should win.

Let the storytelling begin:

Constance Cooper – Carnivores of Can’t-Go-Home

After all our weeks of travel, those final few miles in a wagon drawn by ox beetle seemed the longest of all. The wagon reeked of peat, and the ox beetle periodically dug its claws into the mud and surged forward to free up the wheels. McMurrin, our dour driver, actually managed a chuckle as his insect’s motions flung me and Gwen back and forth. Gwen kept her pet project, a custom high-eye, cradled protectively in her arms.

Every moment I knew that we were getting closer and closer to haunted, hated Can’t-Go-Home Bog, right on the southern fringe of settlement, where no other botanist had ever set foot.

M. Fenn – Chlorophyll is Thicker than Water

“Afternoon, Dr. Yamamoto.” The old woman looked up from the flower seed display she had been studying while waiting.

“Afternoon, Billy. How’s your mother?”

“Good! She told me to thank your partner for the lotion, if I saw you. Her hands are much better.”

“I’ll tell Hina you said so. And how’s your skin doing?”

The boy blushed. “Fine.”

She smiled kindly. “Good. I’ll tell her that, too. Did my order come in?”

She trundled her round frame closer to a display of wind chimes. Hina would like one of these new copper ones, she thought, brushing her calloused hand against the metal pipes. A ceramic frog mounted on the top remained stoic as the chimes tinkled.

Jacqueline Koyanagi – Sensorium

Yora spends her first night in cultural realignment training thinking about the isolation of a life lived between stars.

The Tagli came to Ila, her planet, ten years ago, having crossed unthinkably vast distances in slow increments, bodies and vacuum separated by a mere skin’s breadth of material. Full generations had passed with no knowledge of ground and sky. And then they came, a bombardment of unfamiliar life on Yora’s planet, their twisting ships suspended over fourteen cities like itinerant gods.

Kristin Landon – From the Depths

“Rinna!”

Rinna Heinonen turned, one hand on the hatchway that would let her out of the family quarters, and suppressed a groan. Her fifteen-year-old daughter stood across the small common room from her—in her iso suit, fluorescent orange, its hood and mask dangling around her shoulders.

Rinna sighed. “Just where do you think you’re going?” Sealed in, Petra would be ready to leave Hokule’a with a minimal chance of contaminating the air and sea with her human DNA and microflora.

Petra’s long mass of tight braids was tied back in a ponytail, and she carried her backpack. She smiled tentatively at her mother. “I thought you might need a hand today.”

Shariann Lewitt – Fieldwork

“Grandma, do you think Ada Lovelace baked cookies?” We were in her kitchen and the scent of the cookies in the oven had nearly overwhelmed my childhood sensibilities.

“I don’t think so sweetie,” Grandma Fritzie replied. “She was English.”

“Oh. Mama doesn’t bake either.”

Grandma Fritzie shook her head. “There wasn’t any good food when she was young.”

“Did her Mama bake?”

“Maybe. But not after they left Earth. They only had packaged food on Europa, and no ovens or hot cookies or anything good. That’s why your Mama is so tiny. We’re going to make sure you get plenty of good things to eat so you grow up big and strong.”

Vandana Singh – Of Wind and Fire

I have been falling for most of my life. I see my village in dreamtime: an enormous basket, a woven contraption of virrum leaves and sailtrees, vines and balloonworts, that drifts and floats on the wind. On the wind are borne the fruits from the abyss, the winged lahua seeds that always float upward, and the trailing green vines of the delicious amala — windborne wonders that give us sustenance. But the village is always falling. Slowly, because of the sails and balloonworts, but falling nevertheless. We hang on the webbing, the children and babies tethered, shrieking in joy — and we tell stories about what might lie below.

Aliette de Bodard – Crossing the Midday Gate

Dan Linh had walked out of the Purple Forbidden City not expecting to return to it – thankful that the Empress had seen fit to spare her life; that she wasn’t walking to her execution for threefold treason. Twenty years later – after the nightmares had faded, after she was finally used to the diminished, eventless life on the Sixty-First Planet – she did come back, to find it unchanged: the Midday Gate towering over the moat; the sleek ballet of spaceships between the pagodas and the orbitals; the ambient sound of zithers and declaimed poetry slowly replacing the bustle of the city at their backs.

Melissa Scott – Firstborn, Lastborn

It has been more than a decade since I first set foot in Anketil’s tower, and three years since she gave me its key. It lies warm in my hand, a clear glass ovoid not much larger than my thumb, a triple twist of iridescence at its heart: that knot is made from the trace certain plasmas leave in a bed of metal salts, fragile as the fused track of lightning in sand. Anketil makes the shapes for lovers and the occasional friend when work is slow at the tokamak, preserving an instant in threads of glittering color sealed in crystal, each one unique and beautiful, though lacking innate function. It’s only the design that matters. I hold it where the sensors can recognize it, and in the back of my mind Sister stirs.

Anil Menon – Building for Shah Jehan

“Thermoplastic,” said Kavi, working her mouth as she considered our architectural model, “is not sand.”

I relaxed. If that was her biggest grief, then we were in good shape for tomorrow. It was almost one-thirty in the morning, which meant that only eight hours remained before our final projects were due.

Knock on the door. Then Zeenat popped her head in, her round sleepy face indicating what she was about to ask. “Chai, guys?”

“Yes,” said Kavi.

“I’d like to look over the drawings one more time,” I said. “Make sure it’s habitable. The design is only—”

“She’s trying to say no,” Kavi explained to Zeenat. “You go ahead.”

“So let Velli look over whatever needs to be looked over, we can go have chai.” And then Zeenat added, “My treat.”

C. W. Johnson – The Age of Discovery

It was a milestone, no matter what, and so the lab celebrated. Roberto looked abashed as they toasted him. “Hey, guys,” he said, fidgeting, “I should get back to work.” Everyone laughed. Their supervisor Ms. Thalivar called out, “How fast can you do the next thousand?” and Roberto said, “Well, now that I’ve finally got the hang of it…”

Luo Xiaoxing, the publicist sent over from Shanghai, went around taking images and videos. She squeezed past a couple of technicians and stopped at Edith’s station with her all-in-one raised. “Do you mind?”

Edith shrugged. “The company sent you. But shouldn’t you…?” She pointed with her chin to Roberto.

Terry Boren – Recursive Ice

1. Heuristic

The afternoon wind, cool and rain scented, lifted Bret’s hair away from her neck as she gazed down at the Isar where it slid green and quick beneath the bridge. Her vision was blurred and distorted one moment, absolutely clear the next. Her palms rested gently on the pitted granite of the railing. It was familiar, safe. But though she had done her graduate work at the Planck Institute in Germany, years before, she still could not remembered what she was doing in Old Munich. Something to do with her work? She touched her face, probing gently at the swollen cheek. The eye itself seemed undamaged, though the area around the left socket and the left side of her face were bruised. The cheekbone probably had been cracked. Her cheek was wet, and pain made the eye tear again, distorting the green park along the green river. The wind was picking up. Hoping to reach shelter before the storm broke, she continued across the bridge toward Mariahilfplatz and the frozen spire of its church.

Susan Lanigan – Ward 7

The man from HR was speaking. She could not recall his name, even though it glinted from the bronze-coloured badge he wore below his left lapel. That was because the badge always seemed to catch the intense sunlight coming in through the south-facing glass wall, to which the HR man himself seemed immune, even though it was hitting the back of Vera’s neck so precisely that she felt as if the rays were burning a line on her skin above her collar. Both room and man were unfamiliar to her. Employees from the medicinal chemistry division of Gleich Enterprises rarely got summoned here. But her presence was “imperative”, she had been told, her offence too severe to be overlooked this time.

Kiini Ibura Salaam – Two Become One

Aversion:

Meherenmet glared across the room as she watched an attendant feed Amagasat dates and tiny sips of beer from a serving tray. Disgust spiked through her body. She looks like an aging child, Meherenmet thought.

Morning light filtered into the eye-shaped antechamber, bathing Amagasat in a soft glow. She shimmered in her iridescent blue robe and golden collar and wrist cuffs—all intentionally worn, Meherenmet thought, to boast of her success. But Amagasat’s tremors—that fierce trembling of her hands—overshadowed her finery. Meherenmet doubted that Amagasat could still dress herself, or even attend to her own elimination.

Jack McDevitt – The Pegasus Project

I was sitting on the porch of the End Times Hotel with Abe Willis when the message from Harlow came in: Ronda, we might have aliens. Seriously. We picked up a radio transmission yesterday from the Sigmund Cluster. It tracks to ISKR221/722. A yellow dwarf, 7,000 light-years out. We haven’t been able to break it down, but it’s clearly artificial. You’re closer to the Cluster than anybody else by a considerable distance. Please take a look. If it turns out to be what we’re hoping, try not to let them know you’re there. Good luck. And by the way, keep this to yourself.

“What is it?” asked Abe.

“Aliens.”

Gwyneth Jones – The Seventh Gamer

The Anthropologist Returns To Eden

She introduced herself by firelight, while the calm breakers on the shore kept up a background music – like the purring breath of a great sleepy animal. It was warm, the air felt damp; the night sky was thick with cloud. The group inspected her silently. Seven pairs of eyes, gleaming out of shadowed faces. Seven adult strangers, armed and dangerous; to whom she appeared a helpless, ignorant infant. Chloe tried not to look at the belongings that had been taken from her, and now lay at the feet of a woman with long black hair, who was dressed in an oiled leather tunic and tight, broken-kneed jeans; a state-of-the-art crossbow slung at her back, a long knife in a sheath at her belt.

The flood of data from the solar system probes has led to tectonic shifts in our understanding of our neighbors. High on that list has been the discovery of liquid water in the large moons of the gas giants: Jupiter’s Europa and Ganymede, Saturn’s Enceladus. By many strands of evidence – which include geysers – all three have large subsurface salt-water seas below their icy surfaces (Saturn’s Titan has surface oceans but they’re made of methane and ethane, liquid at Titan’s ambient temperature). In Europa and Enceladus this water may be in contact with a complex silicate core that could supply both directional scaffolding and building blocks; and the orbital friction between the moons and their primaries generates heat dynamos that could give rise to deep hydrothermal vents.

Salt water with a steady supply of dissolved nutrients; an energy source; complex silicates that – according to Cairns-Smith’s clay hypothesis – could act as anchors and template propagators for chiral organic molecules. The simultaneous presence of all these components is a recipe for the development of life.

Life as we know it is based on carbon and uses water as its solvent. Both are unique within their respective categories. Carbon is the best foundational element for complex chemistry by several orders of magnitude: the number and variety of organic compounds exceeds that of all the rest combined. Like its fellow occupants of the fourth column of the periodic table, carbon has an outermost electron orbital that is exactly half-occupied. So the fourth column elements are equally good as electron donors or acceptors, and as a result they can form compounds with just about every other element.

Carbon has an additional almost-unique characteristic: its unoccupied orbital is at such a distance from the nucleus that it can form bonds of the exactly correct strength to create very large and complex compounds. In particular, carbon bonds with itself more or less with the same proclivity that it bonds with anything else. Whatever can be imagined, of any size, shape, taste or smell, can be found among organic compounds, from diamonds to nucleic acids, from limonenes to fullerenes. If a carbon atom’s four available positions have distinct occupants, the resulting compounds are chiral (“handed”), another apparent prerequisite for biomolecules – certainly a decisive attribute of all terrestrial ones.

Silicon, the next foundational candidate after carbon, is a distinctly inferior also-ran. The radius of its outer electron shell is larger, which means that it forms weaker bonds, especially with itself. Generally compounds with more than three silicon atoms in a row are very unstable, unless they are forced into a crystal lattice. And if oxygen is anywhere near it, all available silicon funnels itself into silicates, precluding all other combinations.

In turn, water has several properties that make it the most potent and versatile solvent. This includes its tetrahedral structure (due to its two free electron pairs, which make it a polar compound), phenomenal heat capacity (which makes it a stabilizer), high heat conductivity and surface tension (vital for many cellular structures and processes), transparency to visible light (crucial for photosynthesis) and the anomalous property of becoming less dense when it solidifies into ice (hence a reservoir and refuge). The runner-up, ammonia, shares some of these attributes (including the tetrahedral structure) and might be the solvent of choice at the lower temperatures of Titan’s hydrocarbon seas. Such a configuration is fully deployed in Joan Vinge’s justly famous Eyes of Amber.

If we encounter life elsewhere, it’s a foregone conclusion that its details will differ significantly from ours – and that its differences will dwarf what SF has come up with. Non-terrestrial life may not use DNA or RNA as its basis of genetic transmission; it may use a different kit of starting blocks for energy, scaffolding and catalysis. It will have a totally different repertoire of body plans, sensoria, mental processes, reproductive modes, ecosystems. But it will be based on carbon and will almost certainly use water as its solvent. And just from current percentages, it’s possible that most planetary life may have developed in “roofed ocean” worlds like Europa, instead of the open atmosphere of Earth.

Walking rightward (as is customary) in the Drake equation, the question is: if they emerge, would roofed-ocean lifeforms evolve to complexity? To sentience? To use of technology, whereby they might send the unambiguously civilizational signals still eagerly awaited by SETI? Of course, our horizons are limited by our own intrinsic parochialisms. We cannot easily visualize technology that’s not based on metals and fire. We cannot easily imagine how sentients that never see the stars might nevertheless deduce their existence.

Many of these perceived hurdles are in fact easily overcome. In Forerunner Foray, André Norton postulated a species that directed the building activity of coral polyps. The solution of water-dwelling lifeforms would be direct-to-biotech, bypassing metal forges. Terrestrial cephalopods are remarkably intelligent and are known to use technology (cetaceans are revenants to water, so their intelligence springs from the same foundation as ours). As for guessing the existence of the stars, a species with sensors in the right bracket of the EM spectrum would rapidly become aware of the overwhelming nearby presence of Jupiter or Saturn. Such species might eventually build starships from tissue, like Farscape’s Moya. Beyond that, the specifics of such species might go a long way towards explaining the over-invoked Fermi Paradox: if they sent signals, they would automatically choose their own waterhole frequency.

So far, we’ve seen the exteriors of roofed-ocean worlds. Missions have been planned for investigations of interiors, though their launch dates keep slipping further into the future. In the end, our own vaunted ability to see the stars may not avail us if we choose to turn inward, eventually running out of the metals and fuels that keep our window to the universe open. If we do send out exploratory vessels, we have to be extra careful not to mar the worlds we touch, that may harbor their own tinkerers and dreamers. But it’s my fond fantasy that, before my own life sets, we get to hear of filigree manta rays swirling under Europa’s ice to the radio pulse beats of the giant overhead.

*apologies to Arthur C. Clarke and Stanley Kubrick

Let’s get something out there right away: most science in science fiction is wrong. That’s okay, because most science fiction isn’t actually about science, anyway, but about our relationship with science, exploring how science and technology intersects with our lives.   Frankenstein is about the quest for knowledge, no matter the cost. Twenty Thousand Leagues Under the Sea chronicles how one man’s rejection of the violent machinery of war and power leads him to be the ultimate, terrible instrument of that same violence. The movie Gattaca warns us of the dangers of using a single technological lens for measuring humanity.

Interstellar had Kip Thorne, a prominent Caltech theorist and expert in gravity, as a scientific advisor. But in the end it was the sci-fi equivalent of Peter Pan: if you clap your hands and believe, everything will turn out all right.

As I’ve written elsewhere, a good narrative should be much a good joke: surprising yet ultimately logical. In the original version of Twenty Thousand Leagues Under the Sea, the Nautilus is trapped in a mighty maelstrom; in the movie version the crew are ambushed by a naval blockade. Both outcomes arise naturally from a central character’s underestimate of the forces arrayed against them: in the book, Nemo underestimates the power of nature; in the movie, Ned Land underestimates the cold brutality and hatred of the military. Both are surprising, but make sense in the context of the story-so-far.

By contrast, the plot of Interstellar basically boils down to this: a magical plague nearly extinguishes humanity. Then more magic saves it.

A blight which wipes out an entire food crop is completely believable, especially given our increasing tendency to monoculture. We’ve even seen that in bananas: most bananas in US stores are the Cavendish variety, cultivated by clonal cuttings. Sixty years ago you would have found the Gros Michel variety, but it was all but obliterated by Panama disease, and it is not impossible that the Cavendish may suffer a similar fate.

A single blight which annihilates crop after crop after crop is less believable, if only because: if it hasn’t happened in half a billion years of terrestrial plants, why suddenly now? Worse Michael Caine mumbles something about nitrogen, and people suffocating, which I could not follow; did the blight fix nitrogen, or oxygen? How could it possibly fix enough of either one to shift the atmospheric composition by more than a percent or two–especially given it would have to also draw upon the carbon dioxide in the atmosphere, which is only a fraction of a percent.

This by itself is not an unforgivable scientific (or I should say sciencey) sin. I’m willing to accept a monstrous if highly unlikely plague in order to set the plot in motion.

After some more improbabilities, the accidental heroes launch into space. I’m glad Kip Thorne was able to talk Nolan out of his desire for faster-than-light drive, and the journey to Saturn takes a long time. Limitations, when consistent, provide a good verisimilitude of actual technology. I’m not sure why no one explained to Coop, the talented pilot, what a wormhole was until they were ten minutes from entering it, but, again, for the sake of the narrative I gritted my teeth and accepted it. They were surely some pretty CG effects.

But then we get to the planets. Including a planet orbiting a massive black hole.

Actually, even this I could accept. It is science fiction, after all, and I myself wrote and sold a story (“Icarus Beach”) involving characters surfing the neutrino burst from a supernova. I’m sure Kip Thorne patiently explained that to have a planet deep enough inside a gravity well for a time dilation ratio of 7 years to 1 hour but not be torn apart from tidal forces, it would have to be a really really massive black hole. Hence the name Gargantua. Thorne may have even explained to Nolan that such black holes are only found in the centers of galaxies, which are full of stars and radiation and really not that hospitable to life.

But even that I would accept–part of the joy of science fiction is the sense of wonder and the awe of extreme environments and situations. And the gravitational time dilation, although unrealistically large, fits well into the theme of constrained situations.

I never did get a good sense of the system. Are there twelve planets (like twelve disciples, get it, get it?) and a sun orbiting a sun, or what? The planet of ice clouds seemed, again, unlikely but cool.

But then we get to the mind-numbingly stupid stuff.

Not the falling into a black hole; I rather liked that bit. But Coop communicates with his daughter in the past, and eventually gets to meet her in the future, and it’s apparently all to do with five dimensions. Five dimensions, in Nolan-world, is a get-out-of-jail-free card.

It’s not so much bad science, because the science in the movie is, beyond phrases like “five-dimensional beings,” nonexistent. It’s bad plotting because Nolan is saying And then a miracle occurs. A miracle we expect the audience to swallow, because, science!

Let me remind you: a good narrative should be like a good joke: surprising, but logical.

It’s not logical if you invoke incomprehensible magic. If the audience doesn’t have a fair chance of understanding it, it’s poor narrative.

Even the one part that, superficially, sounded believable doesn’t make much sense if you understand the deep workings of physics. Michael Caine’s character desperately wants to crack the riddle of quantum gravity in order to, I guess, make antigravity and thus easy mass space travel. Another miracle. But they need data, ideally from passing through the event horizon of a black hole, to get it to work.

Physics is fundamentally an experimental science, so superficially this is good. But I could not figure out what kind of data would make a difference. Presumably Caine has narrowed down the range of models–what sort of gauge groups or diffeomorphisms may be involved. But if there is a possibility that a working theory of quantum gravity could lead to antigravity, you could just build the damn things–here’s one device assuming SU(10) supergravity, here’s another assuming conformally invariant diffeomorphisms, here’s another assuming Lorentz-violation at ultraviolet scales (and, for you readers out there, those are all real phrases, not shit I just made up)–and see which one produces antigravity and allows you to build colonies around Saturn. After all, Thomas Edison tried 10,000 different substances for the filament of an electric light bulb before finding one that worked. No need for a suicide mission down a black hole.*

Let me emphasize that the problem is not the bad science–it is that the narrative leans heavily upon incomprehensible science. That’s bad storytelling. And in the end, that’s the worst sin possible in a movie.

*I actually liked the trip down the black hole. And if the movie had ended, right there, I would have liked it a lot more, since up to that point the movie was pretty convincing about how dangerous and indifferent the universe is.

In the last few months there have been spikes of the age-old arguments about the interactions of authors, reviewers and fans. When the three overlap, as is increasingly the case in several genres, it’s no wonder that the injunctions are for discussions to be as uncritically gushing as they’re in fanfic.

It should be no secret by now that I don’t care if people dislike my re/views. Furthermore, my attributes and experiences make it unlikely that I’ll hold a majority view very often even within communities like SFF, futurists, space aficionados, etc. Not that I’m prone to hermetic hermeneutics: after fifty-plus years of avid reading, film watching and gaming, I remain firmly in favor of art being accessible. I like plenty of scifi and fantasy films, even Hollywood ones, even ones that are glaringly imperfect – as long as they’re not in-your-face insulting; as long as they show a scintilla of originality and love of craft.

Recently, people used terms like “curmudgeonly” and “jaundiced” to characterize my dislike of Interstellar of which I briefly said the following, as I deemed it too crappy (in all “five dimensions”) for a full-length review: “Having now seen Interstellar — a loss of three hours I bitterly regret — I’ve concluded that the praise I’ve seen must refer to a film located at the end of a distant wormhole. The clichés, clunkiness, regressive triumphalism and sanctimony are sickening. So is the misuse of Hathaway and Chastain. Interstellar wants to be Contact if/when it grows up. Even McConaughey was more bearable in the latter.” [Though I think Contact would be vastly improved if he was excised from it altogether.]

There have been similar tantrums whenever I’ve disliked a fave-du-jour, although nobody (yet) has called me “a harlot” as someone called Stephanie Zacharek for daring not to have orgasms over Guardians of the Galaxy. But you know what? Even something as smarmy as love standardized for US audience palatability can be done right in SFF films. Love is not McConaughey chewing the scenery, his neck veins throbbing like harp strings. This is love — across several dimensions yet, but without self-satisfied trumpeting:

Mal: It ain’t all buttons and charts, little albatross. You know what the first rule of flying is? Well, I suppose you do, since you already know what I’m about to say.

River: I do. But I like to hear you say it.

Mal: Love. You can learn all the math in the ‘verse, but you take a boat in the air that you don’t love, she’ll shake you off just as sure as the turning of the worlds. Love keeps her in the air when she oughta fall down, tells you she’s hurtin’ ‘fore she keens. Makes her a home.

This makes my eyes sting, even while I know it’s meant to tug at my heartstrings. And if you cannot tell why this is light years ahead of Interstellar‘s “love transcends space and time” pretentious blather, don’t bother reading my (unabashedly unibrow) reviews.

What Are They? Do They Exist? How Do We Find Out?

by Larry Klaes, space exploration enthusiast, science journalist, SF aficionado. The article first appeared at Science That.

Two physicists decide to visit Las Vegas to try their luck at gambling. One of the pair plays craps, where he proceeds to rapidly lose their limited funds as he continually throws one poor roll of the dice after another. His companion, none too pleased at watching their money disappear, demands to know from his friend why he keeps playing this game despite losing every time.

“I may be losing at craps in this universe,” replies the first physicist, “but in an alternate reality, my duplicate is making a fortune!”

Among the biggest mysteries of modern cosmology is the question of whether other universes beyond our own exist in the Cosmos, or Multiverse, as it would be called should they prove to be real.

The general public is aware of the concept of parallel or alternate universes largely through popular science fiction, where they have been a plot device for a long time. Perhaps the best known of those imagined alternate existences is the Mirror Universe of the Star Trek series, where we meet the “bad” versions of the main characters from our universe – or their own fictional “reality” parallel to our real reality.

But do parallel universes truly exist? Are they composed largely of varying degrees of the people and places we know from this reality? Or could they be something far more complex and vast than most science fiction has ever attempted to portray?

If certain physicists who study this concept are correct, then parallel universes exist on a number of “flavors” or levels. Max Tegmark, a professor of physics at the Massachusetts Institute of Technology (MIT) says there are four levels of parallel universes. They range from the first level, where alternate realities exist at distances well beyond the observable Universe we live in, to the fourth, where all mathematically possible universes can and do exist. Many if not most of those universes would not resemble ours at all, obeying entirely different laws of physics. The universes envisioned by Tegmark would be virtually impossible to visit, barring some breakthrough in physics and technology.

Another type of alternate universe is known as the Many Worlds Interpretation (MWI). This theory was first proposed by Hugh Everett III in 1957 and later became the Level Three type of alternate universe in Tegmark’s catalog of parallel existences. Utilizing quantum physics, MWI claims that every action by every person and object creates an infinite number of alternative actions that branch off into their own universe. In this scenario, every possible history and future becomes reality in its own existence separate from our own. This idea was the plot device for the science fiction television series Sliders, which had a group of people travel to alternate Earths every week from 1995 to 2000 via a machine that generated a wormhole.

Could we ever detect or visit these parallel universes? If the theories of current physics are proven true, then the answer would be not any time soon in most cases. However, there has been speculation that four “cold spots” or “bruises” in the cosmic microwave background (CMB) radiation – the surviving remnant of the Big Bang which began our universe some 13.8 billion years ago – are alternate universes which either once quantum entangled with or “bumped” into our reality at some point in the distant past.

If there were parallel universes which collided with our own Universe, one has to ask why they did not create a new Big Bang as predicted by the ekyprotic cosmological model: In this scenario, a physical property in string theory called branes has the branes of several universes collide perhaps once every one trillion years or so. Their collision releases huge amounts of energy to create a new universe. This is what some scientists say is what brought about our Universe in contrast to the current Big Bang model of creation.

There are those who disavow the idea of other universe beyond our own. They correctly state that there is no scientifically empirical evidence for their existence, only theories and mathematical models. While these skeptics are correct in their reasoning, one also has to ask if they need to take another look at our perspectives on the Cosmos over the centuries. Not too many centuries ago, only a few people dared to speculate there were any worlds beyond our Earth or that the Sun was just a very close member of those myriads of twinkling stars in the night sky.

As late as 1920, astronomers were still debating whether the Milky Way galaxy was the ultimate cosmic structure or just one of many billions of stellar islands in the Universe. We now know the latter to be true, adding to our list of cosmic “demotions” from thinking we were the literal focus of existence to just being residents of a rather small world circling a typical star in a galaxy of hundreds of billions of suns, all of which is part of an immense and ancient Universe with at least one hundred billion galaxies if not more.

So are we part of a vast, singular Universe, or is our reality just one of an infinity of alternate existences on a scale far beyond what even our current knowledge can determine? Just as with the possibility of there being extraterrestrial life now that we know many billions of worlds exist in our Milky Way alone, or the historical precedent of Copernicus and others claiming that Earth is just one planet orbiting its sun and not the other way around, it is very tempting to conclude that even something as massive as the Universe might not be the only one in reality. However, we must temper our conclusions on this exciting possibility until the day science determines their existence – or lack thereof.

Two months ago, I mentioned I had made my first fiction pro-rate sale. The story was The Wind Harp, part of a far larger universe that I have been slowly bringing out in the world (Dry Rivers and Planetfall also belong to that universe). I read excerpts of Planetfall and The Wind Harp at this year’s Readercon.

The Wind Harp appeared in today’s Crossed Genres Deadlines issue. Because it was my first pro sale, they also feature an interview with me. For those who read the story I have a small gift: it had a brief coda, excised to meet length requirements. If you leave a comment about the story, either at the magazine site or here and I like the comment, I will send you the longer version of the story, accompanied by Heather D. Oliver’s stunning full-color depictions of its main characters. The image here shows Heather’s preliminary sketches of the story’s two pivots: Antóa Tásri of Ténli and Dor-Nys Teg-Rav of Gan-Tem.

Postscript: My friend Francesca Forrest read the story when I first wrote it and her comments on it made me very happy. Here is her incisive outline of The Wind Harp.

Part 1

Public Perceptions of ETI

Professional SETI researchers and other scientists tend to avoid the public perceptions about aliens, which they find to be full of undisciplined ideas and a tendency to buy into stories and reports about sightings of alien spaceships and their occupants. A fear of being lumped into the fringe realm of pseudoscience is among the top reasons why SETI has stuck with remote searches of distant star systems. However, there is a slowly opening acceptance that some ETI might send probes to our Sol system to observe us discreetly, perhaps in the Main Planetoid Belt or using nanotech devices or even smaller observing and data collecting technology scattered across Earth.

Several chapters of the book are devoted to polling the general public on the subject of alien life. Unrestrained by scientific parameters and paradigms, their theories and beliefs range from having aliens be the saviors of humanity to our destroyers. They also tend to be much more accepting of the idea that many ETI may already be here monitoring us.

In an ironic twist, the public often thinks of the physical appearance of alien beings as essentially humanoids with a large head and eyes, no visible ears, and slim bodies. On the other hand, scientists who focus on exobiology see life taking on many different forms on different worlds due to evolution. Nevertheless, because we know so little about life beyond Earth, a wide variety of viewpoints can be a welcome thing, as there are times when a different perspective on such a subject could be the key to discovery.

Among the most interesting papers in this collection were the ones where different human cultures interact with each other in space and time. In “Encountering Alternative Intelligences: Cognitive Archaeology and SETI”, Paul K. Wason looks at one of the fifteen humanoid species which have shared this planet with us, namely the Neanderthals. Although they existed in Europe around the same time with modern humans and even interbred with each other, their branch of the family tree died out roughly thirty thousand years ago. Clues from the archaeological record indicate that Neanderthals were quite different in many fundamental ways from current humanity despite being hominids which evolved on Earth. Even though their brains were a bit larger than ours, Neanderthal was not as sophisticated in many ways if we go by the evidence that has survived the ages. Regarding how scientists have learned as much as they do know about Neanderthals, Wason said: “Could it be also that one of the best ways of preparing for interstellar communication with other intelligences would be to engage in more study of how human intelligence works?”

Several centuries ago, there were two genetically related but otherwise very different human cultures which did interact with each other and for which we have extensive records of those encounters. In “The Inscrutable Names of God: The Jesuit Missions of New France as a Model for SETI-Related Spiritual Questions,” Jason T. Kuznicki, a research fellow at the Cato Institute, describes what happened when a group of Roman Catholic Jesuits sailed to North America starting in the Seventeenth Century to convert the native tribes living around the Canadian side of the Great Lakes region.

Armed with the tools of their religion, which included the presumptions of French philosopher Rene Descartes and Saint Thomas Aquinas that reason would inevitably bring everyone to the conclusion that the Christian God and souls exist, the Jesuit missionaries soon discovered that the Native Americans they met did not share these views or come to any of the same conclusions as the Jesuits thought would happen in matters of deities and the afterlife.

Here were fellow humans separated by a few thousand miles of ocean and yet the two cultures not only had wildly different views on many things, they also lacked the words of their languages to clearly get across their ideas on spiritual and religious matters. Now imagine what might take place between two entirely different species from separate worlds light years apart. Would an alien species even have a religion?

One aspect of Kuznicki’s paper which was not touched upon were the underlying motives for the Jesuits being in North America and attempting to convert the natives there: The French wanted to secure the New World for themselves from the competing British and Spanish powers. Having the Native Americans as allies would certainly help their cause, either through assimilation or coercion. Should an ETI contact us via interstellar transmissions or arrive in person at our world, this is one aspect of such an encounter that requires the study of historical precedents from our species. The scientists would assume the alien visitors are just explorers, but the historian might think otherwise. Even an ETI that came here with the purpose of doing what it thinks is good for us might have unexpected consequences for humanity.

The Question of Artificial Intelligence

Civilizations Beyond Earth does have its limitations. The focus is mainly on biological entities, which makes sense considering the authors. However, to not offer at least a few papers by some computer experts on artificial intellects, or Artilects as coined by Hugo de Garis, is hardly advancing our knowledge base of all scientific aspects of ETI. In this respect it is no better than focusing on radio as a means of interstellar detection and communication while ignoring Optical SETI and searching for Dyson Shells and alien probes in our Sol system.

Granted, there is a paper by William Sims Bainbridge titled “Direct Contact with Extraterrestrials via Computer Emulation”, which proposes the idea that a person could have themselves downloaded into a computer simulation as an avatar, or at least a psychological reproduction of themselves. Bainbridge envisions the avatars being beamed into space via radio waves to do the exploring and contacting with ETI.

Presumably this would have to be an enhanced version of the humans who choose to go this route, otherwise we encounter the limits of understanding an alien mind that would be little different than if we tried to comprehend an ETI with our own selves. Other chapters do deal with the complexities and difficulties in trying to communicate even basic concepts to an alien species, especially if we have few frames of reference. Would an Artilect with its faster computing speeds and much larger data storage do this better? Would sentience be required for this task or just a highly sophisticated simulation resembling awareness? Perhaps a revised edition of this book will add papers devoted to these questions concerning Artilects.

As Seth Shostak says in his article “Are We Alone?” regarding the Drake Equation, but which could also mirror what is missing and incomplete from this book:

“In other respects, [the Drake] equation might be too cautious. It assumes that all transmitting cultures are still located in the solar system of their birth. This ignores the possibility of colonization of other star systems (difficult, but not forbidden by physics), or the possible deployment of transmitting facilities far from home. In addition, it does not deal with the development of synthetic intelligence – thinking machines that would not be constrained to watery worlds orbiting long-lasting stars. In short, it makes the assumption that “they” are much like “us.”

For those who might argue that we may be unable to deduce the thought processes and motives of artificial minds far larger and faster than our own, the same could be said for any kind of biological alien species: Such beings could take on many forms and be just as inscrutable as an Artilect, yet that has not stopped many humans of all stripes on this planet from offering their views on organic ETI. One advantage with Artilects is that we can work towards actually creating or simulating them and thus have direct access to another intelligent mind.

Unfortunately, many people fear that Artilects could use their superior intellects to dominate or destroy humanity, just as they also expect advanced ETI to arrive in starships with similar goals. Whether that may ultimately happen or not, this general fear combined with a limited education on and cultural ridicule about the subjects relevant to SETI/METI have made their “contributions” to the reality that over half a century after the first serious SETI program, traditional searches continue in a largely sporadic fashion with limited funds, seldom expand beyond the radio and optical realms, and remain dominated by astronomers and engineers.

Human Expansion into the Galaxy

These views and paradigms also extrapolate to interstellar efforts such as Worldships, self-contained vessels carrying thousands of people on multigenerational journeys to other star systems. The goal of these Worldships is to colonize suitable planets and moons in the target system or at least collect resources from them before moving on to other galactic destinations.

How those who will remain onboard for perhaps many centuries will survive and adapt has been studied far more in the pages of science fiction than anywhere else, for obvious reasons. Will those who arrive at their intended worlds be radically different from their ancestors back on Earth? Will their interaction with any ETI they encounter diverge from the initial intentions of those who sent them off into the galaxy? As said earlier regarding Artilects, perhaps a revised edition of this work or a new book altogether devoted to very long term exploration and its consequences on those who make the voyage both aboard the Worldship and upon the places they settle will make inroads to answering these questions.

There is a strong desire or perhaps even a natural reaction to colonize any Earthlike exoworlds as part of some cosmic manifest destiny. Unless we terraform some barren rock, a planet similar to our own will be so not only in terms of size and environment, but also due to having life upon it. Even if none of the organisms on this alien world are sentient (and how exactly will we define that?), do we have the right to introduce terrestrial species there? If the situation was reversed and an ETI arrived at Earth to set up a new home, even if they desired a peaceful coexistence, imagine the reaction from humanity.

Even a robotic mission could cause unforeseen issues in the future. Already at this early stage in our expansion into space we have five probes and most of their final rocket stages heading beyond the boundaries of the Sol system into the wider Milky Way galaxy. Although none of them will be functioning by the time they could ever reach another star system, their very existence drifting and tumbling uncontrolled and aimless through deep space might one day become a problem for beings of which we are completely unaware at present.

We can declare that the galaxy is much too vast and these probes far too small to ever gain notice by any intelligences out there. We can say that any beings who could find these emissaries from Earth would have to be quite sophisticated and savvy with the ways of the interstellar realm and thus capable of dealing with a comparatively primitive, ancient, and inactive derelict from a species such as us.

In the end, however, the truth is that we do not yet know who or what is occupying the galaxy with humanity. We cannot say with certainty how an alien species might react and respond to an unexpected visitor from another world – though we can make some pretty good guesses as to how our civilization would behave in a similar scenario.

As we have already discussed with regards to SETI and METI, again the astronomical scientists and space engineering and technical fields often differ in their views on these matters compared to the anthropologists, sociologists, biologists, and historians. At least some of the gaps between the disciplines were bridged by the incorporation of messages and information packages on the Pioneer, Voyager, and New Horizons space probes. Whether these “gifts” will be recognized and understood by the recipients is yet another unknown factor, but they are a step in the right direction.

The issue of our physical intrusion into the Milky Way will become even more prominent and serious as we develop and launch probes – operated by Artilects most likely – designed to reach and explore other solar systems. In this case, humanity may receive responses from other intelligent beings in a matter of years or decades as opposed to millennia. What may happen and how our descendants might handle an ETI reaction will depend on how far our culture has come in terms of being more wide ranging and inclusive in our understanding of the Cosmos.

Civilizations Beyond Earth may be a slim book, but it is a good introduction to fields that need to be vital parts of any serious discussion of the scientific activities regarding extraterrestrial intelligences. If SETI and METI remain lopsided in their thinking, methods, and executions, the stars will likely continue to remain silent for the human species for a long time to come.

Not to know if we are either alone or one of many living beings in the Universe when we finally have the awareness and ability to answer this very important question would be a tragic shame, an affront to the very reason we have science and a civilized society in the first place. Let us not answer the L portion of the Drake Equation too soon from a lack of wonder, education, and funds.

by Larry Klaes, space exploration enthusiast, science journalist, SF aficionado.  The article first appeared at Centauri Dreams.

SETI, the Search for Extraterrestrial Intelligence, has traditionally operated on the premise that there may be beings in the Milky Way galaxy and beyond who are smart, aware, and interested enough to deliberately attempt to contact other similarly advanced societies in the Universe.

The primary purpose for such an effort would be to alert any potential celestial neighbors to their presence for the exchange of information and ideas about themselves, their home world, and their take on existence. Their methods of transmission would include certain forms of electromagnetic radiation which the various parties should have in common, such as radio and light waves. This Messaging to Extraterrestrial Intelligences, or METI, is considered to be not only less complex and faster than sending a robotic or crewed vessel from one star system to another – barring the discovery of a way to move faster than light (FTL) – but also far less expensive and much safer for both sides.

The alien version of METI is presumed to be conducted by scientists using not their native language but rather some form of basic mathematics for the initial efforts at getting our attention and conducting basic conversations. This remedial arithmetic would serve as the assumed common key to eventually allow both species to use their own conventional languages to exchange more detailed information.

This thinking is strongly reflected in the 1985 novel Contact (and the 1997 film version), the only major work of science fiction produced by astronomer, science popularizer, and SETI/METI pioneer Carl Sagan. In his story, Sagan envisioned a highly advanced, vast, and ancient alien technological civilization which transmits an initial message via radio waves to species they deem potentially worthy of dealing with. One day humanity receives this opening greeting from them in the form of the first one hundred prime numbers, which are digits divisible only by themselves and one. Prime numbers are a pattern produced by no known natural phenomenon.

On SETI Assumptions

If the bipedal residents of the planet Earth can detect and recognize the artificial nature of the primes being sent (“mathematics [is] the only truly universal language” declares the main character Ellie Arroway at one point in response to a visiting senator who wanted to know why the aliens didn’t just speak English) along with the subsequently more complex information which then follows, then one day we might be able join an entire galactic community of civilizations. This society would be similar to the United Nations, only on a celestial scale and with members of many different species from a diversity of alien worlds across space and time, yet somehow all managing to work together for the common cosmic good.

These assumptions, while not implausible, do reflect a particular scientific take regarding SETI, METI, and the nature and behavior of technological alien beings. The question is, does the fact that we have yet to confirm a recognizably artificial signal of extraterrestrial origin after six decades of modern SETI (and a handful of METI) activities mean that our scientific assumptions about intelligent aliens need to be revised, or have we just not been searching long and hard enough? Or perhaps both?

Since astronomer Frank Drake performed the first modern extraterrestrial hunt program in 1960 with a radio telescope search he called Ozma, SETI has traditionally been dominated by radio (and later optical) astronomers, as they are the ones who have conducted the majority of the searches for alien signals to the present era. Their parameters were and are still dictated by the contemporary limitations of what humanity can accomplish when it comes to interstellar distances and the paradigms of their fields and views on intelligent life elsewhere.

As for relevant disciplines outside of astronomy involved in SETI, there have been token representatives present going back to the first modern era SETI conferences, thanks in large part to Sagan. But usually the conferences and the projects were dominated by astronomers, who focused heavily on radio SETI and the technical details of such interstellar communications. Often they would use the famous Drake Equation (N = R* x f_p x n_e x f_l x f_i x f_c x L) as their template but tend to gloss over the parts of that linear equation which were hard to quantify, which included most of it. This was especially done with f_c and L, the fraction of civilizations that develop the means to let others in the galaxy know they exist and the overall lifetime of such technological societies, respectively.

Like most scientists, they felt comfortable with numbers, tangible facts, and mechanics. Why would an alien signal us? Well, because they could, so they would. They wanted to exchange knowledge because the operators had to be fellow scientists, which meant that even though they were alien, they had to think similarly to us, otherwise they would not be conducting METI/SETI. We were looking for versions of us, very specific versions if truth be told.

The accuracy of the statements is attested by Mark A. Sheriden’s excellent and insightful work titled SETI: A Critical History. From Chapter 10, Sheriden gives this quote from Dr. Jill C. Tarter, the recently retired director of the Center for SETI Research at the SETI Institute in Mountain View, California:

Not long after the [1979 NASA Life in the Universe] conference Jill Tarter, a key member of SETI’s second-generation leadership team, acknowledged that SETI was, indeed, “tuned” to find humanoids. “Those forms that we do find in this manner [i.e., a SETI-style search] will be more similar to life as we understand it than other forms that may exist. We put a filter on the problem.”

When asked what she would do differently if starting over again to study ETIs, Tarter responded with an echo of Shklovskii’s complaint prior to Byurakan-II, that the American SETI scientists failed to acknowledge the “complexity” of the problem they faced and, in particular, were ignoring the “humanities and biological aspects.” Tarter said, “I neglected biology, and civilizations, and paleontology.” In other words, she would have paid more attention to the “nature” aspects of the opportunity SETI represented.

Puzzling Out Alien Motivations

Why would an alien intelligence want to contact the stars? The possible motivations for such actions – or lack thereof – are just as important for the success of SETI and METI as figuring out how beings from another world (assuming the majority live on a planet or moon in the first place; another paradigm, perhaps?) might go about sending out signals into the galaxy.

Anthropologists, sociologists, biologists, and historians might have a clue in this area. At present they may have the native dwellers of only one planet to base their research and ideas upon, but at least it is a world with a very wide variety of life and an ancestry dating back at least 3.8 billion years.

These fields and their practitioners are given their due in the book Civilizations Beyond Earth: Extraterrestrial Life and Society, edited by Douglas A. Vakoch and Albert A. Harrison and published by Berghahn Books (New York, 2011). Vakoch, who also edited the book Communication with Extraterrestrial Intelligence (SUNY Press, New York, 2011) is the Director of Interstellar Message Composition at the SETI Institute and Professor of Clinical Psychology at the California Institute of Integral Studies. Harrison is Professor Emeritus in the Department of Psychology at the University of California, Davis.

Reading through the collected papers in Civilizations Beyond Earth reminded me of one of the first works I came across that was directly critical of the parameters modern SETI had laid down in its milestone years of 1959 and 1960, The Inner Limits of Outer Space by Dartmouth professor John C. Baird (Hanover, New Hampshire: University Press of New England, 1987). The author of the first major book on SETI by a professional psychologist, Baird was also part of Project Oasis, a NASA plan in 1979 to help design the multi-channel spectrum analyzer to be used in the space agency’s own burgeoning SETI project.

Baird pointed out how those involved in searching for extraterrestrial intelligences were spending a great deal of their time and resources in designing and building the instruments they planned to use, but not nearly as much in turn when it came to really thinking about what kind of beings might be out there and why they might want to conduct METI at all. Baird’s words and thoughts throughout The Inner Limits of Outer Space mirror what one finds twenty-four years later in Civilizations Beyond Earth. Neither work wants to do away with SETI so much as redefine it to improve the chances for success based on a more realistic or at least more open approach to alien life. The similarities also include the conclusion that even though current SETI is problematical in terms of detecting an actual extraterrestrial signal, it cannot hurt to keep trying for, to quote the current advertising motto of the New York State Lottery: “You never know.”

Among the highlights of Civilizations Beyond Earth which take it beyond the usual examinations of SETI and its related fields is the focus on what the general public, or laypersons, think and say about extraterrestrial life, in particular the intelligent kind.
