I wonder why people use examples of light clocks to explain time dilation. But in reality it violates the speed of light.
My question is, if light speed in constant and absolute, why does a moving mirror velocity vector affect the velocity vector of light, making light to move diagonally? Light moving diagonally means that Speed of light just became speed of light + speed of mirror.
Wouldn't the light blip just miss to hit the opposite mirror after it's emitted?
