Of course it doesn't give the QM correlation,       > Bell's theorem is proven mathematics, after all!              I have in fact been thinking along such lines. I think one has to assume a       uniform, in some way eg on-a-sphere, distribution of hidden variables sent       from the source. Unless .... and this is anathema to all bona fide       physicists, but I am currently wondering if time for an antiparticle is       travelling backwards, as nominally shown in a Feynmann diagram. So a Bell       test starts at say Alice's measurement and ends at Bob's measurement. Or       vice versa. The only way that I can see this helping is by allowing a non-       random distribution of hidden variable values. So I am working on what the       distribution of hidden variables looks like after a measurement. There are       clues found in S-G results and I have been working on this. (Well I have had       a break from physics to work on arranging home deliveries of food to keep me       out of shops etc etc etc)                     >       > > I hope I never need to resort to a multiverse to bring chance into the       > > calculations.       >       > You are mistaken.

And there is no control over which multiverse       'reality' is chosen nor any listing of available multiverse 'realities'. I       am not ready to think about that kind of multiverse just yet. I have my own       version of a multiverse as IMO every particle has a universe within it,       beginning at a creation event and ending with a measurement event /       interaction. Similar to Penrose's CCC but applied to particles.              > [*] PS: Transmitting real numbers by sending only 2 bits is also very       > poorly described by 'collapse-based' QM pictures.
