Have you ever heard that astronauts and even air travellers age slower due to their speed?   (see http://en.wikipedia.org/wiki/Hafele?Keating_experiment ). Clocks move slower when you move faster. If your twin brother takes a 15 hour flight he is about 47ns younger than you when he lands.  
 
Instead of you and your brother,  they could entangle a pair of photons,  send one of them on a 15 hour flight.  When it lands,  that photon is now 47 nanoseconds in the past.  They could then do a quantum teleportation experiment (http://en.wikipedia.org/wiki/Quantum_teleportation ),  and if it works,  would be I guess,  time travel. |
