Getting the Full Picture of Energy = (Time)(Power) and Time Travel

Energy is equal to Time multiplied by Power. Currently in physics "power" is said to be work divided by the elapsed time. Another way of saying it is power is the amount of work done per unit of time. 

Work is defined as force that acts to displace an object. Work is force multiplied by displacement. When we think about time travel we are thinking of universe design. 

In that way in order to truly travel in time we would need to displace every object in the universe, reverting them to the past, or creating the future.

Time is a measurement. Measurements in the universe give us relative locations. 

When you measure the difference between you and a different location in time, you are also measuring the amount of work that has been done since then.
