we say that going down to the smallest level we have definitive evidence for we have this the atom
and its said that the atom is mostly empty space with a nucleus and electrons which orbit it so we can consider the nucleus and electrons to be mass/matter and the empty space to be void so we end up somewhere along the spectrum between the extremes matter and void... there is a lot of empty space but its not entirely empty and this can be extrapolated out to the universe as a whole there is mostly empty space ( as far as we know now ) but within it there are galaxies comprised of mass obiting some kind of center point as above so below |
This shape similarity is due to matter sharing the same laws of physics.
