The question asked of me was how could I explain a 90% chance of seeing Moscow and a 10% chance of seeing Helsinki and I have done so. If only one copy has been made then there would *NOT* be a 90% chance of seeing Moscow and a 10% chance of seeing Helsinki. > > *So I ask again, how do you accommodate a situation in which there is > a 90% chance of being on one branch and a 10% chance of being on the other > branch* And I would answer that question exactly precisely the same way I have already answered it so many times before and absolutely refused to do again until somebody points to an objection I haven't already answered a dozen times before. *> Changing the number of branches (or duplicates) is fine in a > general theory, but not in QM.
