can nothingness exist? Has it ever?

Essentially no, even the void that is space is something.

Plus we really can't quite grasp the concept of nothingness. as to be nothing you probably cannot/could not name it as it would semantically become something then.

I believe death is nothingness until our soul finds it's way back in again. I don't believe anyone is new, just recycled, and our parents are the vehicles. Not to mean each of us isn't unique in this particular journey, or that no spiritual guidance exists, it exists in all of us.

I think it depends largely on how grand you'd like you nothingness to be. I beleive it exists within certain, parameters, yes. Out in space, if you were to look at some small sector devoid of everything (be it light or air or debris) that would certainly seem to define nothingness to me. I mean, there's absolutely nothing there except for nothing. In a larger sense though, no, I dont think you can find nothingness.

Good question... Relative answers.

Comet expert Fred Whipple once quipped, “Comet tails are the closest thing to nothing that is still something.”
