One of the main items discussed in Einsteins "
General Theory of Relativity", is . . . relativity of motion. Speed is relative and is a measurement of one thing compared to another. A car on the highway may be traveling 65 MPH relative to the road, but not to much else. But, now take the speed of light - "C", is supposed to be a constant and not relative. Actually, Einstein referred to the movement as velocity, not speed, which is quite different. In the world of science, some felt that Einstiens "General Theory of Relativity" was in conflict with his statements about light travel, so he clarified this in his "Special Theory of Relativity", and later with his "Extended Theory of Relativity." He explained that the velocity of lightin a vacuum is a constant, not relative to a reference body.
I've never understood it, I have enough trouble fixing tractors. I just hope that if I ever had to ride in a spaceship on a dark night, at the speed of light - I hope the d*mn headlights work.
