As you have been told before, a Lorentz factor of gamma = 2 corresponds to a relative speed of about c∕√(1 − 1∕2²) = 0.867 c. Speed is *relative*; it is measured in a particular frame of reference, and for the *same* body is *different* in different frames of reference unless the frames in question are comoving. > […] > How could both families of the Divine Emperors be rescued if the > station's machine guns destroyed the whole train and the train's > machine guns destroyed the whole station?
