Given infinity, everything has a probability approaching 1.
Given infinity, everything has a probability approaching 1.
Infinite doesn't mean all-encompassing. (There are infinitely many even integers, but the list also excludes infinitely many integers -- the odd ones.)
Even given an infinite universe, some things still might not happen. (Impossibilities, for example; the probability that 1=2 will remain zero.)
Scientific American had a specuial supplement that discussed parallel universes. What I described was a Type I based on the classification scheme given. Type II was based on quantum mechanics. When a quantum 'event' become manifest, all probability outcomes become real, but our universe only follows one path of outcomes. I can't remember the Type III but I think it was based on Brane theory.
