Special Relativity tells us there is no preferred reference frame. Each of the two observers moving relative to each other considers himself at rest and the other as 'moving'. Hence reciprocity of time dilation and length contraction. For observer A the one meter stick of observer B is shorter than his own one meter stick. For observer B the one meter stick of observer A is shorter than his own one meter stick.

Relativity of Simultaneity means Block universe. I cannot see any other interpretation. Can you?
