This is raw theory.
If math concepts are important,
Than the concept of nothing is critical.
Without the recognition of nothing, thing cannot be utilized at all.
Existence is like a coin,
with thing, as the face on one side, and no thing, as the face on the other side.
The thing exists in two locations, where it is (directly),
And where it isn't (as a reflection)
Thing, is an experience as well as a concept (without the concept, it is naked consciousness without physical properties as attributes),
No thing, is purely a concept, hosted by the concept and experience of ,thing.
Although the hosted concept of no thing, is located elsewhere than thing,
That's why the reflection of thing is projected into the location of no thing,
To enable this concept to exist.
It exists where it isn't through existing where it is.
If it wouldn't exist where it is (if no things existed), it couldn't not exist where it isn't (it wouldn't be no thing, it wouldn't even be no, if all there is, is no, than no, is meaningless).
Basically, all no, depends on a yes to exist, without a yes, there cannot be a no.
Like a bagel hole,
It can only exist in the presence of a bagel.
This is not to confuse with unmanifested energy, like the power source of our heart beat,
The source of consciousness.
Nothing can be explained about that, but it definitely does not require visibility or conscious recognition to be.
It definitely is,
And no one ever successfully analyzed and witnessed it.
Although unmanifested energy is out there,
it doesn't mean that every location of no thing is filled with it,
It might not need location at all.
And it might not have an issue with sharing a space with existing matter.
