Astronomers have identified a potential ultra-fast pulsar spinning every 8.19 milliseconds close to Sagittarius A*, the ...

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 ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

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 ...

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

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

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 ...

A prediction made by Albert Einstein in his theory of general relativity has come true as astrophysicists have detected light coming from behind a black hole. A team of scientists made the analysis ...

Einstein's theory of general relativity may be over 100 years old, but a 16-year-long investigation of extreme stars has shown that it is still the best description of gravity we have. An ...

PARIS, FRANCE - NOVEMBER 23: Specialist in the Books and Manuscript department at Christie's, Vincent Belloy poses with the Einstein-Besso manuscript written jointly by Albert Einstein and Michele ...

In another verification of the validity of Einstein's theory of general relativity scientists have used two finely tuned optical lattice clocks to make new ultra-precise measurements of the time ...
