No, Stephen Hawking's last paper didn't prove the existence of a multiverse

Re: As far as I can tell, you can prove

“as our Universe is infinite the bigger objection towards multiverses is where would you put them? ”

I don’t see this problem at all. Most multiverse theories see each universe existing in self contained branes. They speculate about phenomena we may see in this universe when these branes collide in some way thats clearly difficult to imagine without imagining a different type of spacetime like context outside of spacetime. This is of course the main problem with multiverse theories - no one has ever observed anything other than our single universe, or has any evidence for anything other than our single universe.

The multiverse is partly an attempt to explain the weirdness of quantum mechanics, but in cosmology its mainly a way of avoiding god. It allows you to push back the start of everything to a point where people don’t need to think about it, and it helps explain the high degree of tuning that seems to have occured at the start of the universe to make it possible for us to exist.
