You've joined the Physics baseball team and are playing against the Engineer's baseball team. You swing at the ball after a particularly challenging pitch, and hit the ball with your bat in such a way as to make the ball go straight up. It is caught by the catcher of the Engineering team two seconds later (followed by a snide remark). How high did your ball travel?

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.
