The MWI is a cop-out. The problem of nonlocality just gets handed off to whatever process forks the parallel universes - it has to ensure that every universe has consistent outcomes for both halves of a Bell experiment, for instance.
The probabilities in QM should be viewed as subjective, but physicists hate subjectivity, so they talk about hypothetical ensembles. It baffles me that Everett took those ensembles and decided they were real universes.

- akvadrako 6y agoThe MWI van violate Bell inequalities locally by using post-selection; that’s trivial to show. When the universe splits at two distant measurements it isn’t until those outcomes are brought into contact that the matching of worlds needs to happen.
- engineeringwoke 6y agoI know there's math that makes this seem real, but logical arguments make it sound silly. Does the universe split every time the wave function collapses in any form, for all measurements of all atoms in the universe? Isn't that essentially infinite? And how would you prove it if any of this was real?
