Time+Dilation

Time dilation is a phenomena that is shown to occur and explained within Einstein's research and his theory of relativity. The phenomena itself is explained in a supposed experiment wherein one man is placed more toward the center of a body of mass, (deeper in its "gravity well"), and another much farther away from the same body of mass, (in either the shallow ends or completely out of said "well"). If each man had with him a clock of similar construction, it would become apparent that the man closer to the body of mass' clock moves more slowly than the time that each clock may have been set to at starting point, while the opposite is true for the man's clock farther away from the body of mass, (the time of the clock passing much more quickly. This describes gravitational time dilation.
