Faster but later


All clocks in movement (relative, compared to us) are in retard, according to the formula
t’=t/ √[1-vL2/c2]
where t' is the time as we observe on the clock in movement and t on our (at rest) clock.

This is simply because in movement the light-ray reading the clock position has to go a longer, triangular way, like on the picture below. And the light travels always at a constant velocity.

The ray sent perpendicularily comes always back, independently if it is sent at rest or in movement
