Travel through wormholes is possible, but slow
Credit: CC0 Public DomainA Harvard physicist has shown that wormholes can exist: tunnels in curved space-time, connecting two distant places, through which travel is possible. "It takes longer to get through these wormholes than to go directly, so they are not very useful for space travel," Jafferis said. "From the outside perspective, travel through the wormhole is equivalent to quantum teleportation using entangled black holes," Jafferis said. To date, a major stumbling block in formulating traversable wormholes has been the need for negative energy, which seemed to be inconsistent with quantum gravity. Abstract: The presentation, "Traversable wormholes" will take place at 11:21 a.m. MT, Saturday, April 13, in room Plaza D of the Sheraton Denver Downtown Hotel.
