Speed, or the amount of displacement per unit time, is as much a human definition as its compound variables, the meter and the second.
And then there is the subjective notion of speed: not a pure quantity, but the disctinctive quality of your environment trying to push you towards more immediate causation of physical activity. This however is just a way to get you out of the vortex, as Abraham Hicks calls it.
The place of absolute calm which is also called the vortex, the zone, or any of its other names, is where the Grand Overall Design exerts its consipracy to get you the best of your desires come true.
