For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational ...

The sharpest black hole collision ever detected just gave Einstein another win—and raised hopes that the next one might ...

A newly detected gravitational wave, GW250114, is giving scientists their clearest look yet at a black hole collision—and a powerful way to test Einstein’s theory of gravity. Its clarity allowed ...

Albert Einstein won the 1921 Nobel Prize in Physics, but not for relativity—the theory that made him famous. This article unpacks why the Nobel committee hesitated: Alfred Nobel’s rules, distrust of ...

LIGO's GW250114 signal tests Einstein's relativity, revealing black hole properties and confirming key theorems in ...

Planets orbiting dead stars known as white dwarfs might be able to remain habitable thanks to general relativity subtly altering their motion. When stars like our sun run out of fuel, they expand and ...

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. Quantum ...

Quantum Gravity and General Relativity represent two foundational yet traditionally disparate pillars of modern physics. General Relativity, Einstein’s seminal theory, elegantly encapsulates ...

For more than a century, Einstein’s relativity has set a hard speed limit for the universe, with light as the ultimate ...

Astronomers have long faced a strange contradiction: most stars are born in pairs, and ...
