1) That we each experience a slightly different reality is fairly well established.
2) I've always wondered "how different are these realities". It would seem that given the quantum probabilities, these variations would deviate very slightly from "most probably reality" (at our macroscopic level), which is what we perceive to jointly experience.
3) Do we all have a sort of "snapshot" reality, a partial little cross section of the ultimate reality (is our version of electron and other particles only this limited cross sectional snapshot?)
3) For there to be infinite wildly divergent realities, I suppose electrons and other particles would need to be vibrating strings spanning all these realities, with some weird gymnastics to account for causal violations?
