Exactly, but it's defined by Planck, which is the measure of light travelling in a vacuum, a distance, which is essentially based on theory

and it also uses "time" as that unit of measuring that light travel, which is conceptual as well.
I know exactly what you mean, I just like the discussion. ha
It is exactly that though, logical, which is what humans need in order to understand something.
New studies (I read on Google) explain time more as, "Time is an emergent phenomenon that is a side effect of quantum entanglement"
