A nice description of relativistic motion involving length, time and speed. Apparently there is only one speed: "c".
The speed-of-light is a maximum simply becuase it is THE ONLY SPEED. It just depends in which direction of four-dimensional space it is pointing! You are always travelling at the speed-of-light, just not always spatially.
