In the world you know, actions have causes and effects, objects exist as one thing or another, and everything is what it is whether you observe it or not. In the quantum world, those rules go out the window. Take quantum entanglement, for example. You can make two quantum particles interact, then put them at opposite ends of the universe, and measure one. Whatever measurement you get, the other particle takes on a corresponding quality instantaneously, no matter the distance. Well, forget distance — particles can even be entangled through time.
