What happens to TV signals at light-speed?
Einstein's theory of relativity describes how time seems to go slower at near light speed. But, if I were to be inside a train that goes at the speed of light (impossible, i know) and i had a TV screen to see my other 'twin' that is observing me from outside, would he see me like "heeeellllllooooooooo bbbbrrroooooottthhhhheeerrrrr" like really slow? and, if that is true, then would I see him really fast? If both are true, wouldn't the train no longer be travelling at the speed of light because it has to make everything slow, hence also travelling slower? Wouldn't this be a paradox?
