It's a trivial inference. > Simple, I don't find that wording to be a good or intuitive description of the fact that the norm of the 4-velocity vector is always c, and most physicists would probably agree since I don't know of anyone aside from Epstein and Greene who describes it in those words (and Greene probably just adopted it from Epstein without thinking too much about the intuitions it'd tend to give people, since elsewhere Greene seems to argue for a block time view). Does your argument depend entirely on accepting that particular verbal description of a mathematical fact, or do you have an argument which depends only on the mathematical fact itself?
