Actually the speed of light is just a constant that interconnects spatial and time coordinates.<p>In special relativity everything moves with c light speed in a 4-dimentional pseudo-Euclidian space. It means that the light speed constant c is just a measure unit that interconnects time and spatial coordinates. And the actual spatial velocity of a particle is just a projection on the spatial coordinates of it&#x27;s 4-dimentional velocity which always has length equal to c.<p>So the existence of light speed constant seems more like a boundary condition that limits class of possible solutions rather than something connected with the processor&#x27;s clock-speed.
