BTW...even though Space is a vacuum.
You are only counting matter...which still exist but in minute amounts reletive to the surrounding area.
(like a fly in a football stadium)
But when taken over a vast volume, there are vast quantity existing.

Also do not discount the energies flowing through it,
including all types of the electro-magnetic spectrum.
Nor the atomic & sub-atomic particles that you can actually see or maybe not even detect.
Sometimes these only exist for a micro-second.

The space is still made up of the dimensions that define it.
3 spacial, 1 time (so far) and these are all influenced by the Theory of General Relativity/Gravity amongst other things.
The warps created by large masses have enormous reaches.

So Space is NOT "nothing"
it is something.
