I’m a giant idiot so I’m curious if someone could explain something about the idea of a cyclical universe. One of the guys I’m listening to about now, Roger Penrose, seems to attach a lot of meaning to the end of the universe basically just being massless particles.

From that it seems like he asserts that there wouldn’t be any way to measure time and if you can’t measure time you can’t measure distance. From there it seems like he’s trying to say they just wouldn’t exist anymore??

How does that even work?? Just because there’s suddenly a lack of ways to do something doesn’t mean it ceases to exist.

Like I said I’m a giant idiot and am just diving into theories around a cyclic universe and just wondered if someone could explain it better.
