*It's not a matter of, or a case of being squeamish with infinite outcomes. I just don't see how cosmologists can claim the universe is flat -- which means infinite in spatial extent -- if it starts small and expands for a finite time. OTOH, one can claim, as Brent does, that it's infinite in spatial extent from the start. But this is a singularity at the creation time, the BB. A process which results in infinite spatial extent cannot take in place in finite time, or in the case of the BB, in zero time.
