What's it all made of? I think nothing is completely something. Nothing on its own is a useless, non reality. When there is something, like a universe, then nothing has everything.
Space is made of nothing. Lots and lots of waves of nothing. So many bands of empty space at different frequencies, coming from all directions, creating a fabric of nothingness. The absurd part is believing that empty space, however non existent, must build up in some way to create a something. I can't see any other alternative.
