Travel through wormholes is possible, but slow

The new theory was inspired when Jafferis began thinking about two black holes that were entangled on a quantum level, as formulated in the ER=EPR correspondence by Juan Maldacena from the Institute for Advanced Study and Lenny Susskind from Stanford. Although this means the direct connection between the black holes is shorter than the wormhole connection—and therefore the wormhole travel is not a shortcut—the theory gives new insights into quantum mechanics. “From the outside perspective, travel through the wormhole is equivalent to quantum teleportation using entangled black holes,” Jafferis said.
