*So why don't you draw the obvious inference?

AG*but it is different in each branch of the wave function, so reversing this branch does nothing for the others, and does not restore the original superposition. Thus the process is irreversible in principle (nomologically irreversible -- to reverse violates the laws of physics).*But if those other worlds don't exist, it makes no sense whatever to rely on them to establish irreversible in principle in this world (as distinguished from statistically irreversible or irreversible FAPP). It seems you want to have it both ways; that many worlds really don't exist. but quantum measurements in this world are irreversible in principle due the existence of many worlds. AG*
You don't handle uncertainty well, do you. Brent -- You received this message because you are subscribed to the Google Groups "Everything List" group.
