Hear me out, dude. Like...what if, like, the universe is just, like, one giant yo-yo?

"Could the universe be bouncing back and forth out there? Could it be recreating exact copies of itself over and over again, inevitably repeating the same process forever?" That sounds like an old television show repeatedly rebroadcast in reruns- the old narratives repeating themselves ad nauseum each day...

Interesting to point this out. If you had such a universe (finite particles and finite space), you're absolutely going to get every possible combination an infinite number of times (given an infinite duration, of course). You're going to get all those crappy remakes and reruns, along with legitimately interesting alternative versions that are way better than the originals (but you'd need to watch a billion billion duds to get one interesting detail).

I just finished this cool book on Penrose, which mentions cyclical universe(s). He is a very interesting character. I love that he uses old skool transparencies with an overhead projector in his talks (on YouTube!)

Penrose is one of my favorite thinkers to hang out with (mentally, I mean). I like Wheeler a lot too, and I bet you do as well.
