Traversable Wormholes Can Exist, But They Are Not Very Useful for Space Travel, Physicists Say | Physics – Sci

Jafferis and co-authors began thinking about two black holes that were entangled on a quantum level, as formulated in the ER=EPR conjecture by physicists from Princeton’s Institute for Advanced Study and Stanford University. 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,” Dr. 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. “I think it will teach us deep things about the gauge/gravity correspondence, quantum gravity, and even perhaps a new way to formulate quantum mechanics,” Dr.
