My 2 cents;
Is time the basis of motion, or an effect of it? Block time is that fourth dimension along which events exist. The alternative is that motion creates a series of configurations. The difference is that we appear to proceed along this fourth dimension from past events to future ones. If motion creates events, they go the other way, from being in the future, to being in the past. Does the earth travel the fourth dimension from yesterday to tomorrow, or does tomorrow become yesterday because the earth rotates.
Because we are mobile organisms, the prejudice is that we move from one event to the next. The alternative is that we are integral components of these events and all we really perceive is past events receding into memory.
If time is simply a consequence of motion, it is similar to temperature. In fact a dimensionless point in time would be impossible, since that would require the cessation of the motion which created it.
So then the question is; what is space? The assumption seems to be that it is only what is measured, thus in its most reductionist form, it is the three dimensional grid. Do dimensions create space, or simply define it? Dimensions are lines/projections. The three which describe our position on the planet, longitude, latitude and altitude, are not the basis of the planetary space and our position on it, but are, literally, a map of it. Much of cosmology is based on the assumption that motion of matter and energy creates space. That space is created and expands from the singularity. Thus inflation theory can say the initial expansion was much greater than the speed of light, without worrying about how it might affect the vacuum energies of pre-existing space.
But all that leaves open the enormous question of where the singularity came from in the first place.
Consider it on purely geometric terms. If you were to postulate a zero in geometry, would it be the center point of the three dimensional grid, or would it be the empty space of the blank sheet of paper? It seems logical that it is the empty space. It is nothing and nothing is what we say space is. The center point may be the zero point for purposes of reference to other points on the grid, but of itself, it is one, not zero. Zero may be nothing, but it possesses the potential to be anything. Any specific center point, or any number of points might exist in it. Even a universal singularity.
It cannot have limits, as they would be something and space is nothing. We can draw lines and say they are space, but that presupposes the blank sheet of paper on which to draw lines. Dimensions are a description and consequence of space, just as time is a description and consequence of motion.
Dimensions and time are the vectors of the vacuum and the fluctuation.
Time and dimensions have a semi-mystical reputation which the scalars of temperature and volume do not, because we are mobile organisms, living a serial reality.
