Quantum entanglement is a theory that dates back to Einstein, something he called "spooky action at a distance". Theoretical physicists believe that this "entanglement" could be a way of transporting objects across galaxies.

"According to the quantum theory, everything vibrates," theoretical physicist Michio Kaku tells NPR's Guy Raz. "When two electrons are placed close together, they vibrate in unison. When you separate them, that's when all the fireworks start."

"An invisible umbilical cord emerges connecting these two electrons. And you can separate them by as much as a galaxy if you want. Then, if you vibrate one of them, somehow on the other end of the galaxy the other electron knows that its partner is being jiggled."CONTINUE READING >>
