Nothingness is defined as 1) the condition or quality of being nothing; nonexistence. 2) empty space; a void. The American Heritage College Dictionary (3d Ed. 1993). Notice that the definition includes the word "quality", i.e. property, and the phrase "empty space". Your denial that nothingness has properties and that empty space is not nothingness flies in the face of the definition of nothingness itself. Take note that there is nothing in the definition of nothingness that claims that nothingness cannot exist. You are making up your own definition of nothingness, I'm afraid.
