Near, Far

Posted on 08:22 by Unknown
Fiction about the near future, as many people have noted, is most often like a funhouse mirror of the present. It distorts and exaggerates our current fears and preoccupations; it takes current trends and pushes them as far as they'll go without breaking down into incoherence.  It's science fiction in its most purely satirical mode.  Like costume drama films, it contains the fingerprints of the time in which it was composed.  It doesn't go out of date; it loses context.  It's also becoming more and more difficult to do, as the present increasingly becomes its own self-engulfing parody.

Fiction about the far future, on the other hand, digs deep into the past.  Given all the problems of attempting to predict the near-future - black swans, non-linear dynamics, the law of unintended consequences - it certainly makes no sense in consciously trying to project any part of the present on to the far future.  Instead, writers suggest that archetypal human narratives and historical principles will survive every kind of technological change, and reappear in different forms.  James Blish's Cities in Flight series, for instance, is underpinned by the theories of Otto Spengler.  Isaac Asimov's Foundation series was inspired by Gibbons' The History of the Decline and Fall of the Roman Empire.  Frank Herbert's Dune and Gene Wolfe's The Book of the New Sun are different takes on Messianic figures.  Old-school space opera, with its palaces and empires, its sword-wielding heroes and princesses, echo Hollywood's romance with medieval history.  And so on, and so forth.  Like fantasy, the narratives of far-future science fiction are shaped by patterns of Story.  Unless you believe, like those who champion the technological Singularity (aka Rise of the Machines, or the Rapture of the Nerds), that the far future lies on the other side of an intellectual event horizon. That the far future will not only be impossible to predict, but also impossible to comprehend.  That it is an end to Story and the heat death of science fiction, and we cannot utter a single syllable about what follows.  But where's the fun in that?

Size Matters

Posted on 04:27 by Unknown


This brilliantly simple graphic by Adam Grossman neatly illustrates how the scale of human achievement is dwarfed by the size of the galaxy.  We've been emitting radio transmissions for about a century now, and since they travel at the speed of light, the very first transmissions have reached a theoretical distance of one hundred light years from the Sun.  (As Emily Lakdawalla points out in the Planetary Society blogpost where I first found the graphic, the inverse square law means that those transmissions would be so incredibly attenuated as to be undetectable except by the magic of advanced alien technology.)  This means that all of the transmissions to date are contained within a sphere of two hundred light years' diameter.  The graphic shows just how small that is, compared to the size of the Galaxy - if you click to embiggen the image, you'll see that a little blue dot in the centre of the enlarged square: that's us, that's as far as we've reached out.

Space opera's central conceit is to imagine that human influence can extent across the entire breadth of the Galaxy.  Across billions of stars, and about 120,000 light years.  And cosmology operas imagine that humanity can influence the billions of galaxies beyond our own, the fate of the observable universe, and even multiverses beyond that.  Which is why, of course, breaking or getting around the Einsteinian lightspeed barrier is such a common trope, in space opera.  While some writers - Alastair Reynolds springs to mind - have cleverly incorporated the long spans of time required to traverse interstellar distances at sublight speeds into their plots, they usually (as far as I'm aware), limit themselves to so-called near-space.  Conventionally, that isn't much bigger than the volume of the little blue dot.  That image really brings home why it's so necessary to break the speed limit if you're going to have any kind of comprehensible galaxy-spanning plot, and introduce human dramas to the galaxy's vast stage.

Symbiosis

Posted on 07:47 by Unknown
Way back in the 1990s, when I had a day job, I used to do research into plant/animal symbioses, and taught, amongst others things, an advanced course in symbiosis.  All eukyarotic organisms are the products of at least one symbiotic event.  The cells of animals, plants and fungi contain mitochondria, organelles that are, amongst other things, the source of most cellular chemical energy.  Mitochondria were once independent organisms, probably related to Proteobacteria, which entered into an endosymbiosis with the ancestor of eukaryotes - one of the defining steps in the evolution of life on Earth.

In addition to mitochondria, cells of algae and green plants also contain plastids, the organelles responsible for photosynthesis.  These, too, were once independent organisms, and now researchers believe they have identified the host and symbiont that are the ancestors of all species of algae and plants.  It's a hugely exciting piece of work, with equally huge implications.  DNA sequencing shows that the plastid of a species of glaucophyte, a small group of obscure, microscopic blue-green algae, retains genes associated with early cyanobacteria, the photosynthetic bacteria from which plastids are believed to have evolved.  Comparison with the gene maps of a variety of plastids suggests not only that all algae and plants evolved from a single symbiotic event, but also that another organism was involved: 'the DNA includes genes similar to those from ancient bacteria similar to the Chlamydiae bacteria.'  If the hypothesis is correct, the bacteria (which were probably some kind of parasite) have all but vanished, leaving only a few of their genes in plastids, a little like words from the languages of long-vanished civilisations that live on in English and other modern languages.  It isn't a unique phenomenon - one of the more unexpected results of the human genome project was the discovery that genes from retroviruses make up something like 8 per cent of the human genome.  We are the expression of texts from many sources.

Days Of Future Past

Posted on 09:42 by Unknown
I'm digging deeper and deeper into the third draft of Evening's Empires, so apologies in advance if posting here gets a bit sparse. Like a variation of Zeno's paradox, the closer a novel gets to completion, the more of my time and brain it consumes.

I didn't stop writing when I went away last week for my first SFX Weekender, a huge gathering of fans of science-fiction TV series and films, and science-fiction in print.  This was at Prestatyn, a small resort town in the north-west corner of Wales; specifically, at the Pontins holiday camp.  It wasn't for the faint-hearted.  There were at least 4000 fans in attendance, stretching the fairly basic facilities to near but not quite breaking point, forming Soviet-style queues for autographs and food, filling the huge arena where the main, media-related events were held, providing a very good showing at the panels where authors did their stuff.  The median age seemed to be well below that at more traditional SF conventions, and the level of enthusiasm and energy was constantly high.  There were previews of films, and writers of all kinds did their best to sell their new stuff (and there were some serious queues to get autographed books), but what struck me was a large part of that enthusiasm and energy was aimed at the past.  At actors from TV shows long since ended, and films made before a good percentage of the attendees were born.  It's something that's also evident at more traditional conventions, too.  And inevitable, I suppose, given that most afficiendos are exposed at an early age, and are indelibly printed with the stuff they loved first.  Like everything else, the future is never what it once was.

What there wasn't, as someone else has pointed out, was some kind of chill-out space that might have provided a respite from the noise and crowds.  Like the other authors, my timetable wasn't exactly crowded with events, and I spent a lot of time talking with old and new friends.  It would have been nice to have had a space for conversation that wasn't a hundred-foot-long bar (there was a pub, but it was as crowded as everywhere else).  Actually, there was a good quiet space, but it was off-site, at the hotel where I was staying - I decided to opt out of the complete Pontins experience.  There was also a fantastically long and almost entirely deserted beach, butressed with impressive concrete fortifications to prevent erosion.  A good place to walk and think - so good I stayed on an extra day, and missed the inevitable queues for coaches that replaced the railway service on Sunday, after the whole thing ended.
