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

The universe rarely fails to amaze. One of its latest surprises—nicknamed the “Einstein zig-zag”—reveals a stunning arrangement of galaxies and a distant quasar. Together, they produce a gravitational ...

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, ...

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, ...

The faster you move, the stranger time becomes. By imagining how light travels to two people moving at different speeds, Einstein showed that time isn’t absolute. His thought experiment revealed that ...

To understand gravity, Einstein had to rethink space and time as a single connected fabric. He showed that mass bends this fabric, guiding how everything moves. NOVA is available to stream on pbs.org ...
