Einstein-Rosen Bridge

In 1935, Einstein and physicist Nathan Rosen used the theory of general relativity to elaborate on the idea, proposing the existence of “bridges” through space-time. These bridges connect two different points in space-time, theoretically creating a shortcut that could reduce travel time and distance. The shortcuts came to be called Einstein-Rosen bridges, or wormholes.

“The whole thing is very hypothetical at this point.  No one thinks we’re going to find a wormhole anytime soon.”
