That simple! The collapse hypothesis is just a bookkeeping device to get rid of it!True again, the collapse hypothesis was tacked on not because it explained observations better but because some people didn't like those many worlds, so they just said some mysterious process makes them disappear even though they can't clearly explain how this process does this or explain exactly what circumstances are needed for it to take effect. In Sean Carroll's new book, which I just started reading, he says Many Worlds could be called Austere Quantum Mechanics because it adds nothing to Schrödinger's Equation because nothing more is needed to explain observations.
You still need the Born rule, including its intepretation as a probability. Brent -- You received this message because you are subscribed to the Google Groups "Everything List" group.
