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 ...

In 1935, Albert Einstein and Nathan Rosen proposed a “bridge” connecting two symmetrical regions of spacetime to study matter and extreme gravitational forces, not space travel.
