Velocity (d/t) such as the speed of light, is based on space-time, which is an integration between distance and time potential. Time and distance work together in their reference proportions.

It is also possible to dissociate space-time into separated time potential and distance potential. For example, a quantum jump is distance potential without time potential, since distance is transversed without time.

It is not appropriate to calculate velocity from only distance potential, since velocity assumes an integrated space-time. Any movement in space in zero time would be infinite velocity. But since this is only distance potential, it is not velocity per se and does not violate C. Yet it can do things that appear to be faster than C.

This are also examples in nature of time potential without distance potential. If we have a twin pair, they can synchronize in time over a distance, without any time delay due to the space between. Time and information flows without any constraint of distance. This is not velocity either, since technically it is not integrated space-time so the speed of C is not violated.

The idea of dissociated space-time into time and distance potential takes a little getting used to. The dissociation allow us to do things that inertia and energy can't, since energy is based on integrated time and distance potential (wavelength/frequency). If we dissociated energy into separated wavelength (distance potential) and frequency (time potential), we can sequence the impact of the energy differently.
