Speed of light

The speed of light in vacuum, denoted by c, is an important physical constant, and has an important use in pilitron physics. It is defined as:


 * $$c = \frac{\ell_P}{T_P} \equiv 299792458 \mbox{m}/\mbox{s}$$

It is an exact value by definition of a meter. Since the Planck length is a quantum of space and the Planck time is a quantum of time in pilitron physics, then all motion must be at the speed of light. Nothing can ever move faster, and things that appear to move slower actually stop at certain points and go back to the speed of light after some time has passed.
