Teleportation Yes, Time Travel No
Quantum entanglement if what I don't get. Basically, two particles can share the same quantum state, and if the state of one of the particles changes the state of the other particle also changes. The weird thing is if you send two entangled particles billions of miles apart from each other, the change of state in one of the particles will still affect the change in state of the other, as if they are communicating faster than the speed of light.
