  2. Re:Umm...not quite by Repton · · Score: 1 · on Earthlife 2.7 Billion Years Old
    Isn't there some hypothesis that given the number of galaxies, and the number of stars, and the number of planets, there should still be 10^? planets with life on them?

    The Drake Equation gives an estimate for the number of planets that currently support intelligent life, in our own galaxy, given guesses about various quantities. There are a few pages around that will do the calculations for you (ok, it's not exactly difficult, but they do suggest "good" values too).

    Of course, that's only for this galaxy. So I guess you can multiply any number you get by a few billion ...
