Brian Greene: The moving clock is slow, the stationary one is fast (ASYMMETRIC time dilation):

A blatant lie. Einstein's 1905 postulates entail SYMMETRIC time dilation: Either clock is slow as judged from the other clock's system (or either clock is fast as judged from its own system).

And since Einstein's constant-speed-of-light postulate is false (the speed of light is variable as per Newton), time dilation - symmetric or asymmetric - does not exist.
