All those new planets

You may (or may not) be aware of the discovery of many new planets outside our solar system but it has become something of a hot topic.  Universe (that cool blog that recently moved over to ScienceBlogs) had an interesting take on the idea of scale which included the discovery, and  Samuel Arbesman posted an interesting article on what he calls mesofacts that also included the discovery.  He’s right that some things change at a rate that means we just don’t notice them, even things that are important to our continued survival. I blame evolution. We are primed to notice sudden changes —  like the panther that seems suddenly really, really interested in our presence in her and her kits’ personal space. Those kinds of changes make or break our chances for immediate survival and so have taken the lead in our bodies ranking system for what is going to cause a sudden behavioural modifcation (you know like the fight or flight thingy). Often the slow changes (like in climate) do not trigger the hormonal stimulants which jump start behavioural change. After all, a bad harvest or two? We are omnivores, the barley is low? Go eat millet, or the goat, or last year’s walnuts, they last for a long time, even if bitter, and then there’s dandelion greens, it would take a pretty major cataclysm to wipe those suckers out. It is hunger, another kind of hormonal trigger, that causes us to seek out alternate food sources. What it doesn’t do is make us stop acting like giant earth-predators and unbalancing the larger biosphere. That is reason’s role, but it is a newby and apparently not up to the job yet.

As Claire Evans (the writer behind Universe) said, it really is about scale.  She thinks that we are about to experience that wrench that comes with the realization that we are not, in fact, the scale against which the universe developed. And of course what the universe’s non-human scale means is that the things that are most critical to us, the things we think matter the most, almost certainly have no corollary in the vast reaches of all-that-is.

Things like language, mind, awareness, these are human things in that they are the consequence of the evolution of our bodies and the ensuing social change the evolution of our bodies and brains has stimulated (and of course of any other group of creatures that might evolve toward the same evolutionary “goal” of a proactive intelligence capable of rapid learning as a member of a deeply social species). There are so many philosophers that have talked of our capacity for awareness as if it is an attribute worthy of universal acclaim, as if, at bottom, awareness must be a fundamental principle of the universe like mass or the speed of light. This is the power of the meso-world on us. Call it middle earth or midgaard, it is a fantasy universe where things are in fact human-sized and human oriented. Unfortunately for us, but fortunately for the universe, we do not actually live in middle earth.

Now’s a good time to go watch a short video called The Evolution of Life in 60 Seconds.

And that’s just starting with the formation of the earth.  We barely register. In fact the only reason we do is because the creator of the video is human and probably thinks our existence matters. But to be fair I suppose we have made an impact as far as the earth is concerned. Well at least for this particular set of life forms that may well suffer extinction earlier than would have happened without our presence. But extinctions are a regular part of earth history so even this is nothing particularly out of the ordinary. Can you imagine a video “The Evolution of the Solar System in 60 Seconds“? Or “The Evolution of the Universe…”? We wouldn’t be a blip. I mean even the formation of the earth would barely register in the second imagined film.

I sometimes wonder what philosophy would be if we could get outside our middle-earth mindset. And teleology without a human orientation?  That would be fun.  Maybe the universe has been evolving all along toward the mechanisms that make a three toed sloth capable of enormous body temperature variation. Or maybe it is all about bioluminescence. Or the cephlapod ink sac. Or maybe life was just an accident on the way to limestone and the karst lands and their elemental denizens.

Wouldn’t that be fun? — to find out we do inhabit middle earth but that it was created in the image of a set of caves carved by the relationship between water, CaCO3 and CaMg(CO3)2.

Personally I’d rather find out there is no meaning than find out I was an extra in someone else’s drama. That way I can make my own meaning, decide for myself what it all means, and then change my mind depending on how I feel that day. Much more fun, and in keeping with my middle-earth mind.

I mean, really, meaning?  Another of those human qualities that say nothing about the universe, whether big or small. But what else can guide us if not our quest for meaning?

Facts you say? Posh. Tish.
