In the Special Theory of Relativity, Time Dilation varies according to speed of movement through space. Looking down from the north pole, the Earth rotates counter-clockwise and orbits the sun counter-clockwise. The midnight side of the Earth is being rotated into the direction of travel and the noon side opposite. Therefore, people on the midnight side are moving through space faster than people on the noon side. Since there has been no measured difference in Time Dilation between the noon and midnight sides of the Earth, this is proof that the Earth is in fact the center of the universe.
