Quantum entanglement teleportation

Quantum entanglement may allow the eventual deployment of matter teleportation. With quantum entanglement two electrons created together will continue to interact even if separated by a great distance. This continued interaction could allow for long distance information transfer and reconstruction of the original.

Teleportation could allow a kind of time travel that provides a work around to the light speed limit on space travel. The late great Carl Sagan wrote of a method of time travel using wormholes. Wormholes are tunnels in space-time. Sagan noted that if you were able to accelerate one end of a wormhole to a speed approaching the speed of light, then time dilation would cause that end of the wormhole to fall into the past relative to the other end. There is no reason that connected teleportation terminal could not be used in place of wormholes in the same manner.

Star travel could be practical using this method. The closer one gets to the speed of light the slower time passes for the speedy traveler. However the rate of time does not change for outside observers. Therefore it would be possible for a space ship undergoing sufficient constant acceleration to travel to many stars and explore the galaxy. The problem is that the traveler could not return to those they left behind because millions of years would have passed on earth. That is why the return journey would have to include time travel using the teleportation terminals.

Simply leave one of the terminals at your starting point. Take the connecting terminal with you and use it to return home to your date of departure. Follow up trips to the same destination would be even easier once the connection is made.
