Then if God began to gradually slow the speed of light. The universe would continue to take on the appearance of expansion as the speed of light continued to slow. The entire theory of relativity and the energy contained in the universe is vastly changed if the speed of light changes.
Time also changes and the amount of energy in matter changes.
Time would slow to a near halt as the speed of light reached the near instantaneous mark. The amount of energy within the atoms of matter would become almost infinite. Time is relative to the speed of light so time would be appearing to speed up as the speed of light decreases. Thus these stars appear to coming towards us rather than away from us. If the speed of light were increased, the universe would take on the over-all appearance of being much smaller and the stars much closer than presently.
