GRW modifies the Schrodinger equation so it's no longer completely deterministic (Einstein would not have liked that) and as a result on very rare random occasions, about once every hundred million years, the wave function of a particle spontaneously collapses for no reason at all. Despite claims, made by those who haven't read it, that Carroll's book doesn't talk about alternatives to Many Worlds he goes into much more detail about GRW than I have here, but please note that the bottom line fact is *there is absolutely no empirical evidence that GRW theory is true*. So is GRW also a danger to science? John K Clark -- You received this message because you are subscribed to the Google Groups "Everything List" group.
