One aspect of time’s arrow remains unsolved.
“There is nothing in these works to say why you
started at the gate,” Popescu said, referring to
the park analogy. “In other words, they don’t
explain why the initial state of the universe was
far from equilibrium.” He said this is a question
about the nature of the Big Bang.
Could it be that expansion, which proceeded much faster than light, therefore didn't allow entanglement to take place, delaying the heat death of the universe until everything is fully entangled?
If expansion had been slower, would entropy maybe have kept up with it, leaving us as just a single black hole instead of a dispersed, interesting, unentangled, things-are-still-happening universe 13 billion years later?
