Lets say that I'm on a trian moving a velocity of 100 mph, and I release a ball with a velocity of 80 mph in the same direction the train is moving. The ball would appear to move at a velocity of 180 mph to someone on the ground right? Well what would happen if I shoot a beam of light. The light beam can't move at a speed of C + 100 mph, because nothing can go faster than C. To someone on the ground, the light beam would still move a constant speed C.
Why does this happen?
