When Alice and Bob are separated, even from just one centimetre, then it makes no sense to claim that they are in the same world. Alice and Bob can a priori find non correlated results, but they will met only their corresponding Alices and Bobs. The “fully local explanation” is known by everybody: it is the Schroedinger equation. If you simulate the SWE of the system Bob+Alice + their particles, on a computer, and you interview the majority of Alice and Bob, who met after the experiments, they will agree on the correlation, and on the violation of Bell’s inequality, despite we know that everything was local, indeed simulated by a Babbage machine.
