Einstein's special relativity in motion" that nothing can go faster than the speed of light. So that light coming out of the front of the train no matter how fast that train is going, if it's going half the speed of light or if itâ??s going 200 kilometers an hour, that light is traveling at the same speed. I've got bit of a problem here, do you mean in this situation light travels at 10m/s?
