But this contradicts the assumption that it was at a super high temperature at or around the time of the BB. No it doesn't. I can be infinite and high temperature. What gave you idea it couldn't? The temperature behavior of gases at low volume, and the Cosmological Principle. AG IOW, if we run the clock backward, the universe seems to get incredibly small, If the universe is infinite, then it is only the Observable Universe that gets incredibly small. Brent and for *this reason* incredibly hot, roughly analogous to a highly compressed gas. Therefore, it cannot have a flat global geometry, since such a geometry is infinite in spatial extent. QED.
