Well it would be, if it didn't save you from the ugliness of "collapse". It doesn't let you derive the Born rule, but its intention is not to explain the probabilities, which are not explained in standard Copenhagen QM either. Its intention is to provide a framework within which collapse and the associated measurement problem are eradicated. > Besides the fact that > there is zero experimental support for such an idea. > > Bruce > -- You received this message because you are subscribed to the Google Groups "Everything List" group.
