The fundamental goal is maximizing degrees-of-freedom.
Question, does an object standing still, for all practical purposes, have greater degrees of freedom than an object in motion?
I am venturing into a realm I know extremely little of, if any. I am no phys·i·cist. But let me join the fun and say that my sense informs me that an object standing still, for all practical purposes, does have greater degrees of freedom than an object in motion.
The force to slow down an object in motion is symmetrical to the force needed to move an object standing still, keeping the degrees of freedom equal, supposedly.
I guess one way to look at it is, in a vacuum universe with one particle, relatively, how do we tell that one particle moving? Can we?
Arguing your way: Does an object moving at the speed of light not have a bit more inertia than an object at rest? Does motion in one direction not decrease the degrees of freedom of every other direction?
