Yes but why is positive all we care about when it comes to the definition of space? If we fire neutrinos, basically 100% of the atom is 'empty space'. If we fire protons, 99% is empty. If we fire electrons, none is empty.
Why do we say it is mostly empty just because of 2/3 of these things don't interact? Disproving the plum-pudding model was significant but saying the atom is 99% empty space is misleading. We know there are billions of virtual particles appearing and disappearing all the time within the atom and space, they just cancel out.
