O'Dowd can explain Magnetism, but not Many Worlds

Matt O'Dowd has another nice PBS TV Physics video, on How Magnetism Shapes The Universe. I learned a few things. Then, at 15:00, he responds to some queries about a previous episode on Many-Worlds theory.

The questions have no good answers. He says that he will have to make some more videos to explain. Good luck with that. No one can tell how how many worlds there are, or how often they split, or how one can be more probable than any other, or any practical questions about how it all works.
