Strange Posted September 4, 2017 Share 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. ..." Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...
