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

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 ...

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, quantum mechanics and Einstein’s general relativity have stood as the cornerstones of modern physics, yet ...

The sharpest black hole collision ever detected just gave Einstein another win—and raised hopes that the next one might ...

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 ...

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 ...

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 ...

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 ...

Research teams on both sides of the Atlantic have shown that precise modeling of the universe and its contents will change the detailed understanding of the evolution of the universe and the growth of ...

As the Moon’s shadow creeps across the Sun on April 8, physicist Aroh Barjatya will launch a trio of 60-foot-tall rockets into the highest layer of Earth’s atmosphere. The short, sudden darkness of a ...

Cornell professors Saul Teukolsky, astrophysics, and Larry Kidder, astronomy, played an instrumental role in the first detection of gravitational waves, a century after Albert Einstein predicted their ...
