Space is a static lattice, and may be thought of as a succession of unchanging cubes, within which matter plays out its routine, while not affecting space itself, because after all, it's just... space.
There is no space. Space is illusion. The part of this particular space time continuum seemingly unoccupied by particles (which in essence are not particles but waves of energy; powers with potential and actual directions in which they transfer their energy; move their force) are in fact occupied by particles or "particles" eg. forces/energies undetectable by our censors; more notably, most of it is anyhow merely the potential spaces of quantum particles, eg. occupied while not occupied. Our space time continuum, our universe, is merely one big sea of energy (in lack of better ananoly), with dirrefing wave constructions, different waves with different resonance frequencies (constituting all matter, anti-matter, dark matter, energy and anti-energy).
