Nothingness is Unreal

If nothingness indeed exists, how to deal with it as if it's real, as real as stuff you can sniff, touch or swallow, like clams on a half shell being an example?

With "real," you can extrapolate to science fiction tomfoolery,
but with nothingness, you can't do a thing.

The concept leaves you minus not even with a piece of chalk
to draw from it absent zeroes.

Nonetheless, "nothingness" remains a curious word,
better it than no verbal equivalent.
