The catalog of gravitational waves "heard" by LIGO, KAGRA and Virgo has doubled with detections of spacetime ripples.

Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

The Vera C. Rubin Observatory has started releasing its first discoveries: including supernovae, variable stars and asteroids ...

Cosmic voids are different. These vast expanses contain very little matter. In such places, the vacuum of space-time itself becomes the dominant component. If you were positioned at the center of a ...

A recent study which was published in arXiv has found a hug celestial body in space has been reversing its spin and essentially traveling backwards in time.

With the universe constantly expanding, scientists have a hard time finding where its center is. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

A new hypothesis known as the Quantum Memory Matrix (QMM) could help explain some of the biggest mysteries of the universe, including the Black Hole Information Paradox. The idea is that space-time ...

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.

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, ...
