Long range correlations predicted by quantum theory for EPR type experiments and confirmed in spin polarization correlation experiments (SPCE) seem to “cry for explanation”. Different intuitive probabilistic models proposed in order to explain these correlations led to various inequalities which turned out to be violated by QT predictions and by the experimental data. The violation of these inequalities has been incorrectly interpreted as a mysterious non locality of Nature and paraphrased sometimes as: ”two perfectly random dices tossed in two far away locations produce perfectly correlated outcomes”. Of course photons are not dices, correlations are not perfect and the confusion came from imprecise terminology and from the lack of understanding of the true meaning of probabilistic models used in various proofs of these inequalities.
In this talk I will explain why the violation of Bell, CHSH and CH inequalities has nothing to do with non locality of Nature and that it may be explained by some probabilistic model respecting causality and local determinism on the microscopic level. We will also show how one can search for fine structures in various time-series of experimental data in order to check whether QT is predictably complete. A discovery of such unpredicted fine structures would be a major discovery.
