A person A is observing a train traveling close to the speed of light. ... According to Micheleson and Moorly's experiment, this could not happen because the speed of light is the same to any moving object traveling at any speed in any direction. ... In classical theory, if a train is traveling half the speed of light relative to a lamp in a train station, and a person on top of the train is running at half the speed of light relative to the train, then the person on top of the train would catch up to the light coming from the train station. ... Therefore, scientists hypothesized that the...
