You seem to be suggesting that my references to some theories in cosmology weren't entirely accurate. But wouldn't the infinity be the state of initial symmetry before it breaks down? Are you saying the initial state is only supposed to be theoretical?

Anyway, what's the problem with saying there might be actual infinities? Certainly they couldn't exist in nature, but now we're talking about the conditions that give rise to nature. The anthropcentric repudiation of infinities wouldn't be defensible, so you'd have to resort to pragmatism, which is indeed the scientific perspective: we assume there are no real infinities because it's more useful to try to make sense of things and we do so by analyzing them into their parts and by assuming everything is finite and thus intelligible. But that methodological naturalism doesn't rule out anything as metaphysically impossible.

I'm not really sure what your point is about the philosophical use of the quantum foam concept. That or the inflation that produces multiple universes would amount to divine creative powers.
