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

Learn why only 14 out of over 6,000 exoplanets orbit two stars, and how Einstein’s general theory of relativity may be to blame.

One such mystery, described in a recent paper in The Astrophysical Journal Letters, concerns circumbinary exoplanets—or rather, the shortage thereof—in the now 6,000+ exoplanets confirmed to date.

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

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 ...

For over a century, Einstein's general theory of relativity has been key to understanding gravity. But new research suggests this theory "glitches" in the farthest reaches of space. That doesn't mean ...

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 could soon test Einstein's theory of general relativity by measuring the distortion of time. General relativity states that gravity is the result of mass warping the fabric of space and ...

An international team led by Japanese researchers has made a 3D map of 3000 galaxies 13 billion light years from Earth, and found that Einstein’s general theory of relativity is still valid. Since it ...

Albert Einstein had described the special theory of relativity in 1905. The result of Einstein's thinking about light, this theory introduced brand-new ideas to science. It opened up an entire field ...
