Brian Greene: "If you're moving relative to somebody else, time for you slows down."

Brian Greene is lying of course (Einsteinians are pathological liars). Special relativity predicts the opposite: If you're moving relative to somebody else, time for you SPEEDS UP. You will discover this by checking clocks in the somebody else's system against your clocks. You pass by one of the somebody else's clocks, you check it against two of your clocks, and you find that the somebody else's clock is slow while your two clocks are FAST:

Banesh Hoffmann, Relativity and Its Roots, p. 105: "In one case your clock is checked against two of mine, while in the other case my clock is checked against two of yours, and this permits us each to find without contradiction that the other's clocks go more slowly than his own."

Actually this is reductio ad absurdum. The only reasonable conclusion is that time dilation does not exist (your clocks run just as fast as somebody else's clocks) and the underlying premise, Einstein's 1905 constant-speed-of-light postulate, is false.
