Copenhagen would answer that you should stop trusting it at the exact point you make a measurement. Physics is the most precise of all the sciences so it would be reasonable to then ask for the exact meaning of this word "measurement", but when you do Niels Bohr and his friends will respond with bafflegab, which I can only interpret as "shut up and calculate". * *By the way, the integers are not physical objects and neither is the concept of "fast", does that mean that both are unreal? If so, how would things be different if both of those things WERE real? I believe that if the wave function didn't lead to conclusions that make some people, perhaps most people, uncomfortable, like there being many other versions of themselves in a multiverse, nobody would be insisting that the wave function is not real. Physicists whose primary focus is physics at its most fundamental level sure seem to behave as if they thought it's real because they spend about 95% of their time studying quantum field theory. * *> because then you run into problems with instantaneous action at a distance or FTL physical action.* *That's no problem in Many Worlds because you can say the split happens instantaneously or you can say the split propagates at the speed of light, it makes no difference because they both produce identical observable results. * *What observable results are you referring to? There are NONE. You are completely deluded and have no one to blame but yourself. AG * -- You received this message because you are subscribed to the Google Groups "Everything List" group.
