Just like a spider with a line of silk! Did you ever see them throw themselves out into space to weave? They're taking a chance, every single time. They got to do it or else they'd never create anything. But I bet it don't feel good, even to a spider.
I like relativity and quantum theories because I don't understand them and they make me feel as if space shifted about like a swan that can't settle, refusing to sit still and be measured; and as if the atom were an impulsive thing always changing its mind.
