Now let’s determine when the universe “started its trip”. The distance is 800 Mpc, but first convert Mpc into km because the rate, or velocity, is in km/sec. 800 Mpc = _____________________km Use equation (E) to determine how many seconds ago the universe started: _____________________secs

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.
