Fromfiretolife,
What you said about the vacuum is very similar to one of the major philosophical problems that Aristotle was studying.
Zeno's paradoxes were also used to clearup the idea of a vacuum. So we can say that the problem of vacuum was a major preoccupation of all ancient philosophers even up to our modern time's thinkers.
I am also one of the people who study the vacuum. There are now many books on the subject directly or indirectly discussed by each author. One book came to mind is John D. Barrow's 'The Book of Nothing.' The main theme of this book is to relate vacuum to the origins of the universe.
For me, the vacuum contains an infinite amount of something. I cannot describe this 'something' by use of our current knowledge of math because to me our current math is deficient since math deals with numbers. The question that numbers can answer is 'how much and where?' answering the 'where?' needs the definition of an origin, a starting point. but to solve the problem of vacuum, we do need to answer 'when?'. This 'when?' question is related to the definition of the physical concept of time. This definition gives meaning to the word 'before' and 'after' and 'first', 'second', and 'third.' The natural numbers used for these words are the ordinal numbers. The
cardinal numbers are used for 'how much?' and 'where?' The mathematicians don't feel the need to make this distinction but as a physicist, I need the distinction to describe the physical concept of 'direction.'
The 'infinite something' in the vacuum cannot be static. They are constantly in some sort of local movements. One point moves here to there, another point replaces here from there. So the vacuum is full in this sense although the points are always moving here and there.
Associated with each movement is a 'direction.' Since there are infinite points, there are infinite 'directions.' Each point has its own direction and one point will never try to change to another 'direction' because all the other 'directions' already been taken by other points. So each point keeps its own 'direction' for all eternity. This is the principle of directional invariance.
When the points group together they formed two distinct objects which for now we call them the potential mass and the kinetic mass. By doing these distinction, it's unavoidable that two directions of time must exist. One for the potential mass and one for the kinetic mass.
This is simplification at the utmost. Reality is much more complicated. But by defining the physical concept of directional invariance we have a good start to finally answer the question of the vacuum.
