It doesn't make any sense to give something two meanings. True nothingness doesn't exist because if you find something that is more like nothing than you previously thought, then that would be the new definition of nothing and the older concept would be something else entirely. All it means is that our previous concept was incomplete. It is like trying to talk about a giraffe and a true giraffe. A giraffe is a true giraffe, anything isn't a giraffe at all.
If you are meaning that true nothingness is the actual, physical nothingness and nothingness is the conceptual interpretation of it, then all you are saying is that our concept of nothing is flawed since it can't truely explain what we intuitively know as nothing, and refining that concept is kind of the purpose of this thread. And let's face it, this whole "i know but I am not going to say" thing is childish, if anyone has anything of value to add you should put it out there and explain it in a way that others can comprehend or be prepared to explain it until it is understood.
