Forward's method (Drexler's light sails pushed with lasers) currently looks like the best way to travel. It seems to be limited to about .5 c from abrasion. So, 100,000 light years of travel (across the galaxy) takes about 200,000 years. But using (time) warp drive it can subjectively take as little or as long as you want if you (as any nanotech based life form should) have control over your perception of time. At warp 8, (10 exp 8 slower) edge to edge would take 200,000/100,000,000 = 1/500th years. Less than a day while watching 100 supernovas twinkle. >A good point.

Evolutionary psychology is the key to understanding why humans fight wars in the first place. Primitive humans, like every other animal, filled their ecological niche to the limit. The productivity of the environment was unstable, resulting in times (every few generations) of crisis--not to mention ice ages coming along. The evolved psychological response to privation is to make war on a neighboring tribe. Even if a tribe that did so was wiped out, it was normal for some of the young females to be incorporated into the winning tribe. War (from a gene's viewpoint) was better than starvation. 6 million years of this--at least, since chimps also make war on neighbors--has left us with near universal psychological traits (from surviving genes) leading to war and related social upheavals in times of declining wealth per capita. I.e., memes dehumanizing neighbors prior to killing them spread well in times of privation. It will require literally changing human nature to get rid of this "feature," and I am not certain it's a good idea. Growing wealth per capita seems to keep it turned off. The insight behind model is only a month old or so. It will be interesting to see if counter examples of a group of people starting a war in times of *rising* wealth per capita can be found. Evolutionary psychology is a powerful thinking tool. I discuss two other evolved psychological traits, capture-bonding and addictive attention rewards here: human-nature.com/nibbs/02/cults.html >(Actually I am optimistic that that will be the >case.)

Considering how little we understand the roots of the behavior of our own "civilization" that's a good conclusion for now. I suspect though that this trait is going to be a feature of any successful intelligent, top predator species. Keith Henson Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=21658
