Why Search?

In an earlier post, I argued that the current SETI program is not a silly waste of time if we want to search for ET and answer the question of whether we are alone, and I stand by that.  At the time I wrote that post, I didn't think that anyone would be interested in the why question. Of course we want to search, the only question is how, isn't it?  Maybe not for everyone.

All you have to do is to look at people like Frank Drake, Jill Tarter and Seth Shostak, who have

SETI Pioneer Frank Drake

devoted most of the careers to this topic, and you will realize that is is emotionally involving at a personal level, and not just "scientifically interesting".  It isn't purely a matter of scientific curiosity, and certainly not of ambitious scientific careering. 

Well, of course, the small number of people who study a topic are interested in it, and probably find it fascinating in some way.  What about everyone else?

So here is a question to ask yourself: if it was announced tomorrow that science knew for certain that there was another intelligent civilization in this galaxy, what would change for you?  Most adults are highly accomplished at keeping their own little worlds unperturbed.  Would the announcement of a distant ET civilization affect any major decisions you might make about your own life - your job, relationships, where you live, how many children you have, or any religious beliefs you might have?  Probably not you, but the younger generation, yes, because adolescents have left behind the comforts of childhood, and have yet to build their little worlds.  They don't mind being perturbed, and will often volunteer do some perturbing.  With announcement that we know about ET, their worlds just got much, much bigger.

Now it's not just Earthlings alone in the vast, cold universe anymore.  There are the others, possibly many others.  The universe no longer belongs solely to the astronomers, but is now alive, and belongs to everyone.

Advanced Civilizations in Decline - part 1

If something can't go on forever, it won't.  Simple, right?  And yet, the notion that things will always continue to trend as they are is a common fallacy, and leads to real estate bubbles and the collapse of monetary systems.

Moore's Law

In our times, we tend to think of technological progress as something that only accelerates forward.  First we master materials, then energy (thanks to our improved materials), then information (thanks to cheap, abundant, widely distributed energy), and then, possibly something beyond information. We now casually toss around references to Moore's Law, which isn't a law at all, but simply an observation of how our technology continues to improve by some fairly simple metrics: the number of transistors on a chip, the cost of a gigabyte of data storage, and so on. We expect these trends to continue until we have reached a point beyond which no prediction is even theoretically possible.

However, this is a relatively recent trend, and we forget how many ancient civilizations had sophisticated capabilities that have been lost to us, or that we have had to recreate from scratch. They rose, they fell, they lost the recipe. Historians continue to analyze why the great civilizations declined, but once large, complex internal structures form, they begin to differentiate into interest groups that no longer have it as their principal goal to perform their greater function, but rather to maintain or grow their share of the resources flowing through the machinery. When a system fails this way, we call this "collapsing under its own weight."
