11.3 The Mathematics of Slow Time
In the derivation of time dilation, you have the light’s speed at ccos(θ). How is that compatible with the speed of light being constant?
Does the moving clock “kick” the ball of light to move rightward?
Since there is a limit to how fast anything can travel—the speed of light—is there a limit to how much slower a moving clock will tick?
Is there a quick way to estimate the effect of motion on time when the motion involves ordinary, everyday speeds?
