Unfortunately I'm only educated only as far as the science writers explain special relativity. But I also know that the appearance of infinities indicate that the theories are incomplete as Feynman pointed out for quantum mechanics. So I certainly agree, infinite mass, no proof-David so when you wrote: >> Einstein imagined moving away from a clock at the speed of light. The hands never changed position. Time is stopped. Proven in satellites.-This is the same part of the Lorentz's equation but this time the transformation is found in the numerator. -So if we accept that when the transformation goes to zero shows the theory is incomplete, then it is difficult to say Time is stopped. Proven in satellites. as the theory is incomplete.
