The discussion of photon entanglement in this article invokes the debatable premise that physical facts are not real unless they are observed. The article’s own glove metaphor provides a perfect counterexample. Suppose I receive a package of gloves (entangled particles) from a glove factory (particle generator), each glove wrapped individually. I keep one and send […]
