Nothingness

[Sal]

Question:
Atheist believes Universe pops out of nothing.

I don't, and I'm one atheist - but I don't speak for every atheist.

Is there any atheist in the world who can explain what exactly is “NOTHINGNESS or NIHILISM?”

Cheers

"nothingness" is an unintelligible definition that "nothing" is able to exist. Of course, "nothing" is used to define empty sets of something, zero amount of something, then "nothing" has its uses. It's the non-existence bit that is impossible to grasp when talking about "nothing".

Nihilism is the untenable position that, similar to radical skepticism, that there exists no meaning in existence. This is patently false, because if you say there is no meaning you have by uttering "there is no meaning" used a phrase that incurs a concept of its denial. Only way nihilism could be true, would be if nothing could be said and everything was unintelligible and chaotic. But there does exist some level of order and regularity in the Universe, so nihilism is false.
