That clumsy poorly defined assumption was just tacked on by the Copenhagen people because they were frightened by the logical consequence of not doing so. That's why Many Worlds is barebone no-nonsense Quantum Mechanics that contains everything that is necessary and not one bit more. As Richard Feynman said “nature isn't classical, dammit".* *John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* ia6 -- You received this message because you are subscribed to the Google Groups "Everything List" group.
