Re: Help with apparent paradox please?


because since the pulse of light going back is travelling at the speed
of light and the train is travelling near the speed of light then the
pulse of light would get there twice as fast and since the train is
going near the speed of light and the pulse of light directed at the
forward guardsman has to travel all the way up there while the train is
going near the speed of light.

They are all moving at the same speed and so are all in the same inertial
frame. Light reaches both guards at the same time because they are the same
distance away from the source. They break at the same time and the train
stops fine, the guy lives.
