For something to travel at any speed it has to exist. Light does not exist as a physical entity. It is the stimulation of Primary Force. Light does not travel. Think of it this way. Suppose you had a steel bar of x feet. Hit the end with a hammer. Then ask how long does it take for the impact of that blow to move the other end? Instantaneous. No. What exactly is travelling from the point of impact to the other end? It is the movement at the other end of the steel bar that is a result of the blow from the hammer. If the steel bar were long enough there would be a difference in time from the blow to the movement at the other end. Mathematically the difference in time could be calculated and represented as speed. But what was actually moving? It was not the hammer. Light does the same thing to Primary Force as a blow to the steel bar. It forces a movement in the field that can be measured in terms of speed. There is no speed of light, only the time it's impact on Primary Force takes to get from A to B.
