Wow I had been recently wondering about this, what a great coincidence - with the help of Youtube's algorithm of course. And I'm guessing he proposed that there is a 50/50 chance that there is a cosmological multiverse because it would depend on whether the universe is infinite or not. Cool 👍

What's his evidence in support of many-worlds? Isn't it literally impossible to prove and thus should NOT be treated as fact?
