Time at the Speed of Light
According to Einstein’s Theory of Relativity everything is moving. Furthermore, things are moving through spacetime at the speed of light. What that means is that there is relationship between space and time such that it totals the speed of light. Why don’t we (and most matter in the universe) feel the effect of moving very fast? Because most of the matter in the universe is moving so slow that practically all of the energy is used up for moving through time. This is why Einstein also says nothing can travel faster than light. If something were to travel as fast as light then there would be no energy left for moving through time and that object would cease to move through time. Remember the famous example of an object being pulled into a black hole where an outside observer would see that object hang at the event horizon – the point of no return – and seem not to move further. The spacetime theory explains why this would be.
