Space is just emptiness. It won't expand if you put something in it. Just think of it as an imaginary grid.

I know enough to know that this isn't even remotely true, which is what prompted my question to begin with.

Regardless, this also doesn't answer my question even if it was the case that it was just "emptiness". Since space is a dimension through which all things have relative positions/directions, does the distance across the cubic ft of area I outlined increase, or decrease, if we were to add a particle of matter to it?

If it's 1ft in distance across this space, does adding a particle also add a particles worth of distance to that space?

Nothing changes about the space in that area, since space literally is just nothingness, like the previous guy said.

This goes against every paper I can find on Google scholar about the subject. Do you have a source for this?

That’s just the definition of space, is it not?

No. "Nothingness" implies the lack of space. When people talk about the vast distances between objects they talk about "empty space" but not a lack of space itself. Space is separate and distinguishable from nothingness.
