Bell's Theorem: Implications and Misapprehensions

Abstract: Despite the fact that Bell’s Theorem tells us something profound about our universe, there are still many misapprehensions about exactly what it means, even among physicists. For example, it is often incorrectly characterized as disproving hidden variables, or proving action-at-a-distance. Even experts in quantum foundations are sometimes unaware of subtleties concerning the role of an “arrow of time” in Bell’s analysis and the possibilities of using retrocausation to model quantum entanglement in a locally-mediated, spacetime-based framework. This talk will attempt to clarify these and other issues, detailing an explicit retrocausal model which accounts for maximally entangled states.
