Isn't it all waves? It's all waves, isn't it? I mean solidity is an illusion. Basically there's not a particle in the universe. You have the illusion of solidity because some particles are of lower frequencies than others. Basically what you have is a composite of an astounding range of frequencies, from below zero to beyond infinity, and thus all this different stuff, but all this vibrating, but no particles. Nobody's been able to find a particle yet. They keep digging, they keep digging, they think oh I've cornered it, there he is, there he is, and then they get in there and they find out it's just some kind of a coincidence of different frequencies, different vibrations happening, but there's no stuff, there's no particles, it's just a dance, some kind of vibration in space. Who knows?  Maybe we'll find a particle in the next two hundred years.
