Thanks for the answer! I wish someone would explain to me RQM in simple terms, then I could make an opinion about it.

I know this probably doesn't sound good, but I remember reading in Feynman's book how when he was talking to mathematicians about complex mathematical things, he tried to imagine a specific object, like a ball, and then apply what they said to that specific object; and if didn't make sense, he objected. I am essentially trying to do something similar, but with the concepts of physics. So I'd like to hear a story about what happens with the ball in the MWI multiverse, and what happens in the RQM multiverse. (I am not asking you specifically do to that, I just express my wish.)
