Scientists hope to probe the nature of general relativity through a possible pulsar found in the center of the Milky Way, ...

General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...

At the center of the Milky Way, close to the pull of a supermassive black hole, astronomers have found a strange new radio signal that behaves like a slow, steady clock. This object is more than an ...

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

A century ago, Albert Einstein became famous. Sure, he was already well-known among physicists. But the world at large learned his name only after November 1919, when news broke that his theory of ...

According to Einstein's theory of general relativity, gravity results from how mass warps space and time. The greater an object's mass, the stronger its gravitational pull. Scientists have largely ...

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 ...

In the most comprehensive test of general relativity near the monstrous black hole at the center of our galaxy, researchers report that Einstein's theory of general relativity holds up, at least for ...
