In my opinion its best resolution is in the understanding that the wave function or quantum state is not a property of the system itself but of its relationship to an observer, and I think this view is a better reading of what Hugh Everett was describing in his \u201cRelative State\u201d interpretation of quantum mechanics [which was re-presented later (mostly by others) as a \u201cMany Worlds\u201d interpretation where observations (and other interactions) continually cause the creation of new \u201cbranches\u201d (in a way that Everett himself apparently once described as \u201cbullshit\u201d in a marginal note on someone else\u2019s elaboration of the MWI)].<\/p>\n
