A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity ...

The loudest black hole collision ever recorded has just given Einstein’s theory of general relativity its hardest test so far. The event, dubbed GW250114, produced a record-smashing signal-to-noise ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

Ripples in space-time from a pair of merging black holes have been recorded in unprecedented detail, enabling physicists to test predictions of general relativity ...

Researchers believe they have found the signal of a pulsar, the ancient core of a rapidly spinning star, at the center of the Milky Way, near a supermassive black hole. This discov ...

The first image of a black hole, captured in 2019, has revealed more support for Albert Einstein's theory of general relativity. The new finding has suggested his theory is now 500 times harder to ...

Solar eclipses occasion lots of excitement and pique the public's interest in astronomical phenomena. Eclipses can also expand our understanding of the universe in profound ways. In fact, astronomical ...

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 ...

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 ...

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 ...
