Follow up to this question here: If the universe is flat, does that imply that the Big Bang produced an infinite amount of energy? As I understand Inflation theory, some time after the Big Bang, the universe was curved and closed. Then, some magical field started up at exactly the right time and made space expand until it was flat.
A flat universe must have a total amount of energy that's infinite (or zero, depending on who you ask). How did we go from the finite amount of energy in the closed universe of pre-Inflation, to an infinite (or zero) amount of energy? Seems like there's a fundamental problem with Thermodynamics.
