What if wormholes were never cosmic tunnels at all? New research suggests Einstein and Rosen’s famous “bridge” may actually reveal something even stranger: time itself could flow in two directions at ...

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 ...

In a new study published in Classical and Quantum Gravity, researchers have revisited the concept of Einstein-Rosen bridges, the theoretical structures often associated with wormholes. This study, ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen. In 1935, ...

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 ...
