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

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 ...

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 ...

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

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 ...

Since 1915 when Albert Einstein published his theory of general relativity, scientists have worked on testing its limits, and with the results of this 16-year test, it still holds up. Professor ...

A 54-page document handwritten in 1913-1914 by Albert Einstein and Swiss engineer Michele Besso, sold in Paris earlier today for €11.6 million (US$13.0 million). It’s not the most valuable document ...

A handwritten copy of Albert Einstein’s theory of relativity notes was sold for millions at Christie’s auction house in Paris, France, on Tuesday. The 54-page document by Einstein and his friend ...
