One idea I have been hearing about recently is the Janus universe
https://physics.aps.org/featured-article-pdf/10.1103/PhysRevLett.113.181101
Im hoping someone might have a go at giving a layperson explanation of this paper. As I understand they are saying a system will eventually come to a point of low entropy naturally due to gravity and then bounce back at out so there is a reversal of the arrow of time at the bounce point. Is that right?
How is this different to Poincare recurrence?
