Strange Posted September 4, 2017 Posted September 4, 2017 According to this article: https://phys.org/news/2017-09-entanglement-inevitable-feature-reality.html Quote "My future goals would be to see if Bell non-locality can likewise be derived from the existence of a classical limit," Richens said. "It would be interesting if all theories superseding classical theory must violate local realism. ..."

Theoretically, there could exist non-local hidden variables (Bohm outlined such a theory, for example). But regardless, the net effect of Bell's Theorem is profound. Reality is somehow dependent upon how we observe it. " Can anyone explain how Einstein being wrong gets out of the seemingly impossible scenario?

If c isn't the limit on information transfer, then faster (possibly instantaneous) communication isn't a problem.
