Trap Doors in Time and Space: Teleportation, Time Travel, and Escape from Black Holes


http://www.pbs.org/wgbh/nova/physics...m-black-holes/

Luckily for you and me, these are good days for teleporting out of here, traveling through time, and escaping from black holes. Hard as it is to bend our minds about such non-standard forms of transportation, the laws of physics allow and even encourage them. The secret lies in a feature of quantum mechanics called entanglement. Two quantum systems are said to be entangled when they have more information about each other than they can have classically: they "know" more about each other than they have any right to know. Entangled systems possess a kind of quantum intimacy that goes beyond anything that is allowed by the classical laws of physics.
