I would modify the question a little for me:
“How many dimensions are necessary to characterize the universe?”
----------One will not get by without time:
Time presents itself successional attribute of motion, of rather successional attribute of the universe.
(Two directions of time are enough to describe the motion – to mark it out towards some relative instant, i.e. to differ two separate phases of motion:
past and a
future, i.e. one parameter, as past = -future)
----------And one will not get by without space:
The space presents itself localizational attribute of motion, or rather localizational attribute of the universe.
But space “spreads” from any of its point to all directions. So if we choose any of these directions as parameter, we’ll have infinite number of “spatial” parameters, but only any three (inter-perpendicular) of them (6 directions) are enough to characterize (describe) any exact, precise location.
I.e.:
The
3D-space presents itself conventional localizational attribute of motion, or rather attribute of the universe.
So it comes to
4D-conventional parameters of motion, or rather 4D-conventional parameters of universe.
