Wikipedia: http://en.wikipedia.org/wiki/Rietdijk-Putnam_Argument Quote: "Two people pass each other on the street; and according to one of the two people, an Andromedean space fleet has already set off on its journey, while to the other, the decision as to whether or not the journey will actually take place has not yet been made. How can there still be some uncertainty as to the outcome of that decision? If to either person the decision has already been made, then surely there cannot be any uncertainty. The launching of the space fleet is an inevitability." If so, how is this compatible with free will of Andromeda citizens, random events or quantum mechanics? One observer seems to live in universe where the andromedans are predestined to launch the space fleet. Either the paradox is flawed, or there is something seriously wrong with the relativity of simultaneity.
