That is one way of presenting the same I presented.

But Nothing is indeed an idea/word, and the brain is based on/makes use of ideas/words.

The point I made is how some words are flat and other words are shaped in more complex manners.

The word 'nothing' placed next to the word 'family' for instance, shows how one does not entail any complexities, whereas the other captures a complex state among certain people.

Still, there is one spot that makes it obvious that Nothing is actually not a singular 'item'. As soon as a family member dies, we have a missing person. This death often takes time to accept before we establish the new and current meaning of the word 'family'.

The spot of nothing can be enormously important.

This is also easy to show with zero, presented here with its two versions in 010.

In '010' we see two different kinds of zero.

The first zero can be put in front of 10 or be left out. Either way, the total is 10. Its use is voluntary and can be left out.

The second zero cannot be left out because 10 would then end up being 1; the total would not remain the same without the second zero. It adds nothing, but it occupies a position and that occupation is meaningful.

As such, we have the Nothing by itself as one way of seeing Nothing, while in the other way we can declare that the Nothing does have a structural function.

The universe, for instance, changes if we make the Nothing unimportant or important.

When the Nothing is unimportant, then the universe can be seen as a unit, if so desired. Everything is then connected on some level to everything.

When the Nothing is (at times) important, however, then the universe can be seen as a collective of material outcomes. The Milky Way is then not connected to any other galaxy (other than via happenstance). The universe can then not be seen as a unit, but is then rather a collective of parts.

A complete, total, and utter Nothing exists then, for instance, between us and the trillion upon trillion (and more) galaxies there are in the universe. Only those galaxies close to us have a tiny bit of connection with us (such as the Andromeda Galaxy which will collide/combine with our galaxy in about 4.6 billion years).

Because of our use of Nothing, we have two different outcomes. A united universe of some kind, a unit, or... the lack of a united universe, never a unit.

For the brain, Nothing is a vital aspect that sometimes is also totally unimportant.

Thank you for your reply. I appreciate it.
