Since Newton used it, Edgar obivously thinks Newton was a moron.

If one throws out this (so far unproven) assumption, it become logically possible to explain violations of Bell's inequality while preserving realism and locality. It also fits in with the block universe cnocept, by the way. One of the reasons physicists are so wedded to the BU concept, by the way, is that no coherent alternative has ever been proposed (except for ones that require extra, unecessary, time dimensions). -- You received this message because you are subscribed to the Google Groups "Everything List" group.
