classical mechanics - What makes a space a real space?


By "real space" I mean a space in which physical particles move.


Consider a color sphere and let a bunch of objects "move" on its surface. "Move" means "change colors". Let there be some rules governing the changes of color, maybe giving rise to something like inertness or collisions. .



Under which conditions will we be willing or forced to think of the movements as real movements in real space?
