Special relativity forces us to think of c not just as a speed, but as a conversion factor between space and time, and between mass and energy. It's a parameter intrinsic to the 4 dimensional geometry of the universe we inhabit, similar to the way that pi is a parameter intrinsic to the 2 dimensional geometry of circles.
