I was wondering if anyone knows whether there exist strictly local interpretations of quantum mechanics. I understand that Bell's theorem tells us that any hidden variable theory must be non-local if it is to give QM. But what about other interpretations such as many worlds? It is obvious that wave function collapse is non-local so any interpretation that views this as a real process must be non-local. This is why my guess is that MW could be local since there is no physical collapse. What about decoherent histories?
