" The thing is, these two tiny things are so tangled together, that if you separate them and put them millions or even billions of miles apart, they still know about each other. They still relate to each other.
If one of them changes, the other one changes - immediately, in the same millisecond. They each know what is happening to the other one, even though they might be light years apart. That's how intimate they are. That's how entwined their destinies are. "
