My statement is just that if it is proven within the context of an interpretation these two might have the greatest plausibility. But "We provide a derivation of the Born Rule in the context of the Everett (ManyWorlds) approach to quantum mechanics." https://arxiv.org/pdf/1405.7907.pdf So what is the issue? @philipthrift -- You received this message because you are subscribed to the Google Groups "Everything List" group.
