Motion is detected visually thru a light signal,Isnt Einstein time dilation really visual time delay?

Question

If light was intanteneous wouldnt we then be able to measure the velocity of the motion? so what happens in the proper frame is is seen the same way in the observer's frame?

Answer 1

yes and no you have kinda the right idea but what your referring to is just a delay of light to the eye, no light bending time it self.

Answer 2

Time dilation has nothing to do with visual delay; it is simply the delay of visual acquisition due to the time light takes to get from the moving object to the eye.

Delay = D/c
