Assuming that the universe is spatially infinite, extending outwards in all directions without end, and is consistent with what we have thus far observed, and predict to find (and predict to be out beyond our reach), in the cosmos, then:
Does everything that is physically possible, happen? Just by merit of being physically possible in our universe, does 'it,' happen, somewhere out in the universe?
P.S. Doesn't everything that's possible happen an infinite number of times? The only practical difference being how often something occurs, which would be based upon its likelihood of happening, based upon physical laws.
