And would *that* mean that the totality of events up to that point would repeat in reverse… Not to mention, what happens when it all collapses into a single point and subsequently explodes in a new big bang. Is it all new, or will things repeat again…?

Quite mind-blowing for an 18-year old.

Come to think of it, it’s still fun to speculate at 58.
