My apologies for the seemingly unrelated comment, but I do not understand why 'spooky action at a distance' has to be 'action at a distance' and not photons getting entangled when created.
I.e. why couldn't it be that a pair of photons are generated with their properties already in such state that, when measured, a correlation is present? the photons don't communicate, they are already in the appropriate state when measured.
- jostylr 8y agoThat is what Bell's work showed is not possible. The inequality he derived assumes the values already exist and then proves that a certain inequality for the predictions must be satisfied. This is without specifying the actual theory, just simply that the values already exist in the right correlations. Experiments has proven that the inequality is violated. Thus, the properties cannot be determined beforehand. So either there is a connection that is, essentially, faster than light, or the results of the experiments do not become finalized until compared (that is, the researchers first reading the results exist in a multi-state, allowing for various outcomes yet to be determined [this is what the many worlds view basically is] ). http://www.scholarpedia.org/article/Bell%27s_theorem#Bell.27s_inequality_theorem http://www.scholarpedia.org/article/Bell%27s_theorem#Bell.27...
