Einstein–Rosen bridges may reflect a two-directional structure of time that preserves information and hints at a pre–Big Bang universe.

The puzzle Einstein and Rosen were addressing was never about space travel, but about how quantum fields behave in curved spacetime. I ...

Wormholes have long served as science fiction’s favorite shortcut through the cosmos, but a growing body of theoretical physics research suggests they will never function as tunnels. That does not ...

An Einstein-Rosen bridge is a hypothetical, yet unproven, feature of spacetime. In theory, these so-called wormholes provide a shortcut through the Universe to connect two separate points in ...

Physicists are still debating wormholes as if it were 1935, with the ink barely dry, on a chilly, fluorescent morning in a university corridor—the kind with ...

In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a striking concept in a 1935 paper. In that work, they described an abstract ...
