Communion Of Dreams

“Grrrr.”

“Easy, Alwyn.”

“Grrrrr! GRR!” His growls grew from a distant throaty rumble into a near bark, as we came around the corner across from the lawn with the sprinkler. Yeah, my dog was growling at a lawn sprinkler. This is not normal behaviour for him.

But in fairness, it was an odd lawn sprinkler. A big plastic dog lawn sprinkler. White, with black spots. Looked vaguely like a St. Bernard in size and shape, but a Dalmation in coloration. The hose attached to the tail, which fanned water all over while doing this odd jitterbug wag. Looked like some overgrown kid’s toy. Which it might well be. Since I don’t have kid, I don’t keep track of these things.

Anyway, it was clear that my dog thought that it was some kind of bizzaro-dog with a serious bladder problem. Perhaps an Alien Zombie Dog or something. So, he did the natural thing: he growled.

As I’ve noted before, I’m a big fan of the original series Star Trek and of Gene Roddenberry. But one of the things which has always bothered me about that series and most other SF television or movies is the fact that so often the Aliens are depicted as some variation of humanoid, albeit with a little makeup and prosthetics as the budget would allow. Though, in fairness to Roddenberry (and others in different series now and then), sometimes there was an attempt made to depict alien life as being just completely odd, unlike anything we’ve known or seen. This notion that extraterrestrial life might be difficult to even identify is a staple of good Science Fiction, of course, and one of the topics which I explore at some length in Communion of Dreams (and part of the reason why we never meet the aliens responsible for the creation of the artifact). It gets back to “Haldane’s Law“:

Now my own suspicion is that the Universe is not only queerer than we suppose, but queerer than we CAN suppose.

(Which is decidedly similar to Sir Arthur Eddington‘s attributed comment: “Not only is the universe stranger than we imagine, it is stranger than we can imagine.” But since I am talking more about life here than astrophysics, I thought I’d go with the evolutionary biologist…)

But now actual science has perhaps caught up with Science Fiction. From the New Journal of Physics comes a paper discussing what seems to be the discovery of inorganic life. The abstract:

Abstract. Complex plasmas may naturally self-organize themselves into stable interacting helical structures that exhibit features normally attributed to organic living matter. The self-organization is based on non-trivial physical mechanisms of plasma interactions involving over-screening of plasma polarization. As a result, each helical string composed of solid microparticles is topologically and dynamically controlled by plasma fluxes leading to particle charging and over-screening, the latter providing attraction even among helical strings of the same charge sign. These interacting complex structures exhibit thermodynamic and evolutionary features thought to be peculiar only to living matter such as bifurcations that serve as `memory marks’, self-duplication, metabolic rates in a thermodynamically open system, and non-Hamiltonian dynamics. We examine the salient features of this new complex `state of soft matter’ in light of the autonomy, evolution, progenity and autopoiesis principles used to define life. It is concluded that complex self-organized plasma structures exhibit all the necessary properties to qualify them as candidates for inorganic living matter that may exist in space provided certain conditions allow them to evolve naturally.

That’s a bit dense, so let’s go to the critical bit from the Press Release:

‘It might be life, Jim…’, physicists discover inorganic dust with lifelike qualities.

Until now, physicists assumed that there could be little organisation in such a cloud of particles. However, Tsytovich and his colleagues demonstrated, using a computer model of molecular dynamics, that particles in a plasma can undergo self-organization as electronic charges become separated and the plasma becomes polarized. This effect results in microscopic strands of solid particles that twist into corkscrew shapes, or helical structures. These helical strands are themselves electronically charged and are attracted to each other.

Quite bizarrely, not only do these helical strands interact in a counterintuitive way in which like can attract like, but they also undergo changes that are normally associated with biological molecules, such as DNA and proteins, say the researchers. They can, for instance, divide, or bifurcate, to form two copies of the original structure. These new structures can also interact to induce changes in their neighbours and they can even evolve into yet more structures as less stable ones break down, leaving behind only the fittest structures in the plasma.

So, could helical clusters formed from interstellar dust be somehow alive? “These complex, self-organized plasma structures exhibit all the necessary properties to qualify them as candidates for inorganic living matter,” says Tsytovich, “they are autonomous, they reproduce and they evolve”.

Obviously, there’s more to it, and it is worth reading at least the entire press release, or the full paper if you have a chance.

There’s another possibility, of course. This one can best be summed up as being that life is “a dream within a dream“. The latest popular version of this is “The Matrix“, wherein life is an artificial reality construct, designed to keep the human ‘power cells’ docile. But this too is an idea extensively exploited in Science Fiction, with many different variations on the theme. Of late, this idea has been more and more tied to the concept of a ‘Singularity’ , with speculation being that we are just some version of post-human research/recreation as a computer construct. And in a piece published yesterday in the NYT titled “Our Lives, Controlled From Some Guy’s Couch” this gets the mainstream religion treatment:

Until I talked to Nick Bostrom, a philosopher at Oxford University, it never occurred to me that our universe might be somebody else’s hobby. I hadn’t imagined that the omniscient, omnipotent creator of the heavens and earth could be an advanced version of a guy who spends his weekends building model railroads or overseeing video-game worlds like the Sims.

But now it seems quite possible. In fact, if you accept a pretty reasonable assumption of Dr. Bostrom’s, it is almost a mathematical certainty that we are living in someone else’s computer simulation.

. . .

David J. Chalmers, a philosopher at the Australian National University, says Dr. Bostrom’s simulation hypothesis isn’t a cause for skepticism, but simply a different metaphysical explanation of our world. Whatever you’re touching now — a sheet of paper, a keyboard, a coffee mug — is real to you even if it’s created on a computer circuit rather than fashioned out of wood, plastic or clay.

You still have the desire to live as long as you can in this virtual world — and in any simulated afterlife that the designer of this world might bestow on you. Maybe that means following traditional moral principles, if you think the posthuman designer shares those morals and would reward you for being a good person.

My own prediction is that unless we are extremely fortunate, and extremely open-minded, we’ll stumble badly in our first encounter with any real extra-terrestrial intelligence. Chances are, we’ll completely mistake it for something else, or try and see it through our limited perspective, not unlike how my dog mistook a lawn sprinkler for a wierdly-colored St. Bernard. If we’re lucky, we’ll survive that first contact, and then go on to see the universe with less prejudiced eyes.

If we’re *very* lucky.
