My friends had asked me a question which I thought was rather troubling and provoking. The problem is that is actually seems to violate the law that states that nothing travels faster than the speed of light. Their question was: Suppose two planets (planet A and planet B) which are one thousand light years apart to be connected with a strong cable. Then the living beings on planet A tugs at the end of the cable. Now the problem is: Would the life forms on planet B, which is the other side of the cable, feel the pull instantly even when the two planets are a thousand light years apart?
