AG The facts are events in spacetime. There's an event F at which the front of the car is even with the exit of the garage and there's an event R at which the rear of the car is even with the entrance to the garage. If R is before F we say the car fitted in the garage. If R is after F we say the car did not fit. But if F and R are spacelike, then there is no fact of the matter about their time order. The time order will depend on the state of motion. Brent Since the car length can be assumed as arbitrarily small from the pov of the garage, why worry about fitting the car in garage perfectly, and then appealing to difference in spontaneity to prove no direct contradiction between the frames? It seems like a foolish effort to avoid a contradiction, when one clearly exists. AG -- You received this message because you are subscribed to the Google Groups "Everything List" group.
