Physicists from the University of Pennsylvania, working with colleagues at Arizona State University, are examining the limitations of a framework that aims to unify the laws of physics throughout the ...

In physics, there are two great pillars of thought that don't quite fit together. The Standard Model of particle physics ...

The Laser Interferometer Gravitational-wave Observatory (LIGO) is no stranger to making history and breaking records. In 2015 ...

Two colossal black holes among the most massive ever seen collided in deep space, creating gravitational waves that rippled across the cosmos and shook the foundations of astrophysical theory.

The very concept of black holes seems improbable. Albert Einstein infamously refused to believe they could exist, even though ...

A new method to analyze gravitational-wave data could transform how we study some of the universe's most extreme events—black ...

Gravitational-wave detectors have captured their biggest spectacle yet: two gargantuan, rapidly spinning black holes likely ...

The powerful merger, designated GW231123, produced an extremely large black hole about 225 times the mass of our Sun.

Scientists develop a more accurate way to analyse gravitational waves, that could give us a clearer picture of the Universe’s most extreme collisions, led by the University of Portsmouth, England.

What occurs when two black holes, each greater than a hundred Suns, smash into each other in the shadows past our galaxy? In ...
