It doesn’t. Either the 2nd law is incomplete or the idea of bouncing universes starting from scratch with a clear state in entropy is impossible: https://arxiv.org/abs/1010.5513

I can see why it might look like that from the outside, but the set of mathematical results that led up to it actually come from the angle of, “let’s try to prove that traversable wormholes and the negative energy densities required to create them are impossible.” In trying to prove that, you learn a lot of interesting things along the way: 1. Negative energy densities are a universal prediction of all quantum field theories, and therefore are not as outrageous to think about as one might naively believe. [0] 2. The amount of negative energy density permitted by quantum field theory is NOT…
