i've been reading Brian Greene's latest book and have enjoyed his excellent analogies and metaphors for understanding quantum mechanics (among other things). IANAP, but one thing that comes to mind as a theory is that the concept of particles that are non-local having an effect on each other is perhaps explainable if you expand the definition of spacetime to include a 4th spatial dimension. in other words, it appears, in the spacetime recognizesd, that there are two particles that are separated by "space". is it possible that they are only separate in the 3d spatial model we are familiar with, but that in a 4th spatial dimension they share a locality? if i am way off here, please accept my apologies.
