Semantically,
Nothing has two connotations :
Nothing(L) (in logical terms) is the null set - represented by the symbol 'Ø'.
Nothing(A) (in the abstract) is 'that which does not exist'.
But, 'that which does not exist' doesn't exist. It isn't the empty set. It's not a set at all.
To consider
Nothing(A) would be
not to consider.
To perceive
Nothing(A) would be
not to perceive.
To understand
Nothing(A) would be
not to understand.
Nothing(A) neither has nor lacks attributes. It is neither present nor is it absent.

Imagine an inert, infinitesimal point in space - and then try to imagine that same point NOT in space. Logic requires definition.
Nothing - in the abstract context - is undefined. It doesn't exist. It is a fiction which has no physical manifestation in the Universe. Within the realm of logic
Nothing is not 'non-existence', it is the existence of the null set - the value of 'Ø'.
