Stross: how I ended up as a science fiction writer

lifeCharles Stross is recounting the long journey to his current position has one of the stars of British science fiction, beginning with his first steps into education during the years of Thatcher:

I already knew (from an early age — 12 or so) that I wanted to be an SF writer. But there was a fly in the ointment — a fly called Margaret Thatcher. I turned 15 in 1979, the year the conservatives won an election and the Thatcherite revolution swung into action.

Unemployment soared from around one million to over three million in twelve months as the UK experienced the worst industrial recession since the end of the second world war (largely caused by Thatcher’s dramatic decision to cut most of the state-owned industries off at their knees, on the assumption that the workers would find new and more productive jobs sooner rather than later — a misplaced assumption, as it turned out).

I come from a middle-class background; I could expect to go to university, but not to rely indefinitely on parental hand-outs. “You’ll need some kind of way to earn a living while you’re trying to write,” the careers guidance teachers told me.

A familiar story, as this happy university dropout will affirm (except it was Blair instead of Thatcher and the economic collapse only really started after I left).

The first watery exoplanet?

An alien coastline?I’ll wager you’ve caught at least a hint of this story already: astronomers reckon they’ve located the first serious candidate for a water-bearing exoplanet:

… new calculations – made possible by the discovery of “[Gliese 581] e” – show that the larger planet is squarely within the so-called “habitable zone,” neither too far nor too close to the star around which it orbits to support life.

“Gliese 581 d is probably too massive to be made only of rocky material, but we can speculate that it is an icy planet that has migrated closer to its star,” said co-author Stephane Udry, a professor at Geneva University, in Switzerland.

“It could even be covered by a large and deep ocean – it is the first serious ‘waterworld’ candidate,” he said.

A waterworld, eh? As Gareth L Powell put it, maybe we should dispatch Kevin Costner immediately

More seriously, a wet Gliese 581 d is only a possibility as yet, but it’s a possibility that shifts the odds on there being life elsewhere in the universe. When (or perhaps I should say “if”) we manage to confirm the presence of liquid-phase water on other planets, we’ll have to concede that the likelihood of life evolving elsewhere is not as remote as was once thought… which will doubtless be immensely upsetting to some people, but makes me feel pretty good.

New-found native life in the stratosphere

skyWhile the needle-in-a-haystack search for life on other planets continues, we still consistently find new lifeforms on Earth when we look in the right places. Our oceans are still a source of biological mystery, but that’s not the only place that extremophile life can be found: the Indian Space Research Organisation recently announced the discovery of new bacterial species in the stratosphere:

Three bacterial colonies, namely, PVAS-1, B3 W22 and B8 W22 were, however, totally new species. All the three newly identified species had significantly higher UV resistance compared to their nearest phylogenetic neighbours.

“So what,” you may be thinking. Well:

The precautionary measures and controls operating in this experiment inspire confidence that these species were picked up in the stratosphere. While the present study does not conclusively establish the extra-terrestrial origin of microorganisms, it does provide positive encouragement to continue the work in our quest to explore the origin of life.

Does the Earth harbour a ‘shadow biosphere’?

alien desertDoes the Earth harbour forms of life unrelated to the carbon-based DNA-powered stuff we know about? “Impossible,” you might say, but as pointed out by astrophysicist Paul Davies, we wouldn’t know – because we’ve never looked for it.

“Our search for life [has been] based on our assumptions of life as we know it. Weird life and normal life could be intermingled, and filtering out the things we understand about life as we know it from the things we don’t understand is tricky.”

The tools and experiments researchers use to look for new forms of life – such as those on missions to Mars – would not detect biochemistries different from our own, making it easy for scientists to miss alien life, even if was under their noses.

Alternative biochemistry is inherently a speculative field, which is why it has made plenty of appearances in science fiction – Rudy Rucker has dealt with similar ideas before, for example, and Futurismic columnist Mac Tonnies has theorised about the potential of Earth being home to beings we are not able to recognise as such.

Finding examples of alien life here on Earth might add credence to theories like panspermia – but, more importantly, it would suggest that the likelihood of life developing elsewhere in the universe is closer to one than to zero. [via SlashDot; image by Haeroldus Laudeus]
