What nothing is not

There is no nothing
nothing doesn't mean empty space
space is not nothing
vacuum is not nothing
nothing is nothing, and nothing is nowhere

Theory: There is no such thing as nothing. There was never a time when nothing existed, and never a place where nothing existed. Nothing is not possible and never will be.

Proof (semantic and literal): There is no time when nothing could have existed, or it would not have existed. There is no place where nothing exists--or it wouldn't exist.

Conclusion: There is no literal edge of the universe, where on this side it exists and on the other, nothing. It is not possible, semantically or literally.

The Universe is an infinite but closed system.
