Two ways of measuring how fast the universe is expanding disagree, a puzzle known as the Hubble tension. Tiny magnetic fields from the Big Bang may offer a solution.

New observations from the James Webb Space Telescope (JWST) suggest the cosmos may be much older than once believed. For decades, scientists have held that the universe is about 13.8 billion years old ...

An astrophysicist explains what wormholes are and how these theoretical space-time tunnels have popped up in the solutions to a set of decadesold equations.

A physicist proposes that the universe is not empty space, but is a viscous fluid, fueling the expansion and contraction we see.

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, ...
