Uncertainty propagation in nonlinear dynamical systems is a field of study that explores how measurement inaccuracies, initial condition errors, and model approximations evolve within inherently ...

It sounds like the setup for a joke: If radio waves give you radar and sound gives you sonar, what do gravitational waves get you? The answer might be “GRADAR” — gravitational wave “radar” — a ...

To understand why scientists are excited about detecting a new background, just look to the history of studies of the CMB. There’s a new cosmological background in town. In June, researchers from the ...

A physicist has proposed a bold experiment that could allow gravitational waves to be manipulated using laser light. By transferring minute amounts of energy between light and gravity, the interaction ...

The results are included in a new paper from the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the VIRGO gravitational-wave detector, which presents analysis of 10 stellar-mass binary ...

A soaring cosmic symphony surrounds us; its notes emerge from massive celestial objects crashing together hundreds of millions or even billions of light-years away. But scientists have only tuned into ...

Gravitational-wave detectors have captured their biggest spectacle yet: two gargantuan, rapidly spinning black holes likely forged by earlier smash-ups fused into a 225-solar-mass titan, GW231123. The ...

Scientists first detected ripples in space known as gravitational waves from the merger of two black holes in September 2015. This discovery marked the culmination of a 100-year quest to prove one of ...

You may not feel it, but at every single moment you are being ever-so-slightly stretched and squeezed by ripples in space-time. These ripples, called gravitational waves, are caused by the movements ...

When the densest objects in the universe collide and merge, the violence sets off ripples, in the form of gravitational waves, that reverberate across space and time, over hundreds of millions and ...

In a groundbreaking discovery, the LIGO-Virgo-KAGRA collaboration detected the loudest gravitational wave ever observed, confirming Stephen Hawking’s area theorem on black holes. The event, GW250114, ...
