Doug: thanks for the additional material. It exactly encapsulates my initial thoughts: there are so many possibilities in terms of time, space, number of galaxies and solar systems, that it just GOTTA be true!
But taking Page's Model Thinking class made me wonder, after hearing Hawking on TED, that I might be able to build a bit more of a model. So I looked into star types and their evolution and ages and was quite surprised that the number of generations of stars is a small number. Granted they overlap and possibly a Population II star could support life, .. but if we're betting on Population 1 stars, we may be seeing widespread life starting within a billion years or so of each other, not spread out over the 14BY of our universe. Nick: mainly that star formation and percentage of heavy elements would greatly change the probabilistic models of "intelligent" life. I was taken aback by the thought. And what INTERESTS me is that one can make scenarios that are a bit more concrete than my prior thought that there are so many worlds and time, that intelligent life is inevitable. My model is becoming more like within the era of formation of Population 1 stars is a reasonable boundary condition. Still a lot, and still intelligent life looks pretty probable. But less so than before. In general, I think other intelligent life forms are interesting to think about. I bet for example, they are pondering prime numbers as we do. I bet they have found that "chance" does not mean "no structure" .. i.e. random processes can create highly structured results. Evolution and Us for example. -- Owen On Sat, Mar 31, 2012 at 1:23 PM, Nicholas Thompson < [email protected]> wrote: > Dear Owen, **** > > ** ** > > I don’t know how to ask this question without sounding churlish.**** > > ** ** > > But why is this question INTERESTING?
