A link between particle physics and gravity equations, called the double copy, applies to Hawking radiation, creating a new ...

General relativity stands as one of the bedrock theories in modern physics. Its strange view of relative time and space has been confirmed by countless experimental and observational tests, from ...

The science fiction film Project Hail Mary brilliantly uses authentic science to underscore the human drama and narrative tension of the story. Based on the novel by Andy Weir, the story revolves ...

ANACORTES — Later this month, Anacortes High School students will bring to life the seemingly unrelated stories of about a dozen people who have touched one women’s life in ways both invisible and ...

Time has an arrow: It only ever seems to move in one direction. The future is always unknown to us, while the past forever remains locked and inaccessible. And yet, the vast majority of the laws of ...

For decades, astronomers have used distant supernovae as cosmic lighthouses to test fundamental physics and to measure the universe. For Joseph Farah, a fifth-year graduate student at UC Santa Barbara ...

When black holes collide, the crash generates ripples in the fabric of spacetime—gravitational waves. These distortions travel far out into the universe, but by the time they reach Earth, they have ...

The loudest collision ever recorded between two black holes has allowed scientists to test Einstein’s theory of general relativity in unprecedented detail, showing that the physicist’s predictions ...

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 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 ...

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 ...
