> You can say that there is no such a thing "state of particle 2" there is just the "entangled state". But this, in turn, invites the discussions of "physicness", "realness", etc of "states" and "wavefunctions". Which seem to be sidestepped due to the overwhelming success of the theory. I mean, we could sidestep it, but it's a fundamental part of the formalism of quantum mechanics. It's even worse if we consider quantum gravity: is the spacetime also in a non-separable state? I'm not sure about local non-hidden variable theories though, to be honest > If not too bothersome, could you discuss possible (EDIT: possible consequences that impact) experimental results of this? There are none
