Such a process is unphysical. Therefore, a universe infinite in spatial extent cannot come into being, and is therefore uncreated. AG A more direct way of understanding my claim: If you don't believe the universe can instantaneously expand to infinity, it must be finite in spatial extent, since no progressive expansion, no matter how fast, or for how long, can be infinite in spatial extent. Therefore, given the premise, the universe must be finite in spatial extent and cannot be flat. QED. AG I sent the physicist/cosmologist at Case Western a short email reminding him that if he assumes the universe (presumably, the unobservable part) is infinite in spatial extent, it always was, since there is no transition or evolution from finite to infinite, or vis-versa, he was also implicitly assuming that the universe began with an *instantaneous* transition to infinite in spatial extent at T=0. No reply. No thank you. As expected. AG -- You received this message because you are subscribed to the Google Groups "Everything List" group.
