It fits together if you take into account the fact that gravity makes the almost even, high-density plasma in the early universe extremely unlikely. Gravity wants to clump things, but for some reason they weren’t very clumped when the universe was young. That’s why the initial state had low entropy. Once it evolves forward in time, sure enough, the plasma begins to clump, forming stars and galaxies—because that’s likely to happen. This doesn’t happen in the batter, because the gravitational force isn’t strong enough for such a small amount of matter at comparably low density. It’s because of
