You also get the same Big World effect from the inflationary scenario in the Big Bang, which buds off multiple universes. And both spatial infinity and inflation are implied by the Standard Model of physics.

How exactly do you get spatial infinity from a big bang in finite time? The stories I hear about the big bang are that the universe was initially very, very small at the beginning of the big bang. If it was small then it was finite. How does an object (such as the universe) grow from finite size to infinite size in finite time?
