Very smart physicists and mathematicians posit that even if the universe is very big and not even ‘infinite’, there may be multiple copies just like us out there right now.

I do think the Eternal Return is more probable than not. There can only be something rather than nothing. And ‘something’ repeats. Forever.

To counter those saying ‘Infinity need not overlap’. True. But universes are closed sets that operate via natural laws. They may vary universe-to-universe, but this fact means universes aren’t simply ‘random values’.

Yes, I’m certain it repeats. In fact, I’m hopeful to live this life over again. Or, perhaps on repeat, but with small variations.
