On January 14, 2025, a pair of black holes with nearly identical masses crashed together roughly 1.2 billion light-years away, producing a gravitational wave signal so clean and powerful that it ...

NEW YORK & STOCKHOLM--(BUSINESS WIRE)--Scientists at Applied Physics, an independent group of scientists and engineers who advise companies and governments on science and technology for both ...

An international collaboration of astrophysicists that includes researchers from Yale has created and tested a detection system that uses gravitational waves to map out the locations of merging black ...

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

The universe has delivered the loudest gravitational wave ever recorded, and it appears to have given Einstein’s theory of general relativity one of i.

On Sept. 14, 2015 astronomers “heard” two black holes crashing into each other at close to the speed of light. This discovery was a watershed moment in physics and astrophysics, heralding an entirely ...

For the first time, researchers have simultaneously measured the gravitational waves and the light from two merging neutron stars. ‘Multi-messenger astronomy’, combining the observation of ...

Dark matter is one of the most puzzling mysteries of science, with a huge range of suspects being investigated. In a new study, astronomers have searched for clouds of hypothetical, ultralight ...

Due to come online later this year and packed with state-of-the-art optics, Advanced LIGO is aiming for a direct detection of gravitational waves that will open a new window on the universe, say Iain ...

Think of spacetime as a rubber sheet, which is stretched when there are large objects such as stars and black holes. Gravitational waves are the waves on this cloth, which are produced when the masses ...

Gravity feels reliable—stable and consistent enough to count on. But reality is far stranger than our intuition. In truth, the strength of gravity varies over Earth's surface. And it is weakest ...

The 2017 Nobel Prize in Physics was awarded Tuesday morning to three pioneers of the Laser Interferometer Gravitational-wave Observatory, which announced last year the world's first direct detection ...
