I understand that this is a much debated issue, so I will try to be precise in order to narrow the question. Bell inequality violation rules out Local Realism. From this, I understand that by giving up just one of the two conditions (Locality or Realism) one could generate a viable model. My questions:
- Could we provide a local and non realistic model that reproduces the observed correlations? (in particular I do not see how a local theory can reproduce correlations outside of the light cone)
- Could we provide a non local and realistic model that reproduces the observed correlations?
- What about QM? I this (non) local and/or (non) realistic? Is this just a matter of interpretation?
Claims on these points in the literature are often unclear and (to me) confusing (see for example http://www.physics.drexel.edu/~bob/Entanglement/aspect_nature446.pdf) so I would like to see explicit model for my points 1. and 2.
