Excuse me.... but even within SR an object that recedes with the double distance during an elapsed period of time must have the double velocity. that is not the case in your little mathematical journey into the unknown. Last time i checked it out 2v / (1 + v^2 / c^2) - v / (1 + v^2 / c^2) did not equal v / (1 + v^2 / c^2) |
