Stephen Hawking:
'If one carried out experiments with moving bodies on the train, all Newton's laws would still hold. For instance, playing ping-pong on the train, one would find that the ball obeyed Newton's laws, just like a ball on a table on a track. So there is no way to tell whether it is the train or the earth that is moving.'
