EPR paradox, 4

Entanglement is said to involve “correlations” of states, but the correlations are not the result of a transmission of information, electrodynamic fields, or other known ways of projecting energy across the space between two physical systems. Therefore, it is argued, no demonstrations of entanglement can involve causation as strictly defined. This argument is tautologically true, but it does not explain how entanglement can be explained.

One solution that has been attempted is to argue that the correlations are predetermined by some kind of hidden variables. But these arguments have been strongly questioned by the Bell inequalities test, and although loopholes have been urgently sought[,] the consensus so far has been that the test validly rules against hidden variables.
