Everything in the universe is vibrating on one level or another. Maybe space-time itself is nothing but a membrane through which a sort of "sound" passes, and all the subatomic particles in the universe are just like the sand on this vibrating plate. They jump up and organize themselves into forms in response to energy from who knows where? Maybe the universe is just a big iTunes visualizer for the eternal song of creation...
Yeah, maybe I'm full of crap, but I'd rather dance to a song no one else can hear, than pretend there's no music at all in the world.
