And that very very small part is our entire observable universe. And that very very very small part of the Universe is still in thermal equilibrium, or close to it. *> It makes more sense to me that the universe was already very close to > thermal equilibrium during inflation, * As I also explain in my previous post, there is no theoretical reason to expect the pre-inflationary universe to be anywhere even close to thermal equilibrium, and the less fine tuning of initial conditions that a theory needs to match current observations, that is to say the less often you have to say "that's just the way it is", the better.
