Based on the theory of quantum fields and thermodynamics in curved spacetime there is every reason to think the system was not in equilibrium. Also the initial state of the universe was very clearly extremely low entropic and so likely not in equilibrium. As these posts grow in numbers of responses I generally drop them. They become difficult to follow and after they reach 100 the list is partitioned in ways that make it even harder.
