A record-setting collection of precisely measured gravitational waves reveals new information about how black holes behave and evolve
Astronomers have released the newest list of gravitational-wave detections, almost doubling the number of known signals from colliding black holes. The post Gravitational-Wave Det...
We are used to thinking of gravitational waves as messengers from catastrophes in space, the ringing of spacetime after black holes collide for example. But our own Galaxy hums wit...
Since gravitational waves were first detected in 2015, instruments including LIGO, Virgo and KAGRA have picked up a steady stream of signals from colliding black holes, building a...
Picture the Milky Way not as a silent pinwheel of stars but as something that quietly sings. Scattered through it are millions of pairs of dead stars, mostly white dwarfs, whirling...
A new detector-based method clarifies how gravitational waves should be measured in an evolving universe. Imagine trying to measure a ripple on the surface of a pond while the pond...
Researchers from the University of Glasgow's Institute for Gravitational Research are celebrating the publication of a vast new treasure trove of gravitational wave detections, hai...
Dark matter may alter the dynamics of colliding black holes and leave a signature in their gravitational-wave emission. The post Novel gravitational-wave model sheds light on dark...
The loudest crash of gravitational waves ever heard provides an intriguing way of studying event horizons, the boundaries at which nothing can escape the grip of these cosmic titan...
Black holes are some of the most mysterious objects in the universe, but they aren't always silent. When two black holes are close enough to each other, they spiral toward one anot...
In space, someone can hear you scream, in extreme enough circumstances: by using gravitational waves from the collision of two black holes, scientists have heard signals from close...
A new gravitational-wave catalogue reports 161 additional black hole mergers, bringing the total to 390 detections. Scientists at the University of Glasgow’s Institute for Gravitat...
The discovery of a completely new type of gravitational wave could reveal what happens near a black hole’s event horizon
If, in space, no one can hear you scream, it seems that you can actually hear the sound of a crash when two black holes collide. Using the loudest gravitational wave ever heard, tw...

When two black holes orbit each other, they eventually spiral inward and collide in one of the most violent phenomena in the universe. The event is so energetic that it significant...
До сих пор горизонт событий чёрной дыры рассматривался как математическая абстракция — некая граница невозврата, после прохождения которой ничто не могло покинуть чёрную дыру. Опре...
The question of how gravity interacts with the quantum world has long perplexed physicists, but a non-quantum theory of space-time could present an answer
Author(s): Michael SchirberA proposed gravitational-wave observatory on the Moon might gather more information than previously thought, thanks to geology.[Physics 19, s89] Publishe...
The LIGO–Virgo–KAGRA (LVK) detector network has a new trick up its sleeve to improve the instruments’ sensitivity to gravitational waves: it’s called Astrophysical Calibration and...
Black holes are often misunderstood to be just that: dark and mysterious voids that are somehow akin to Alice in Wonderland’s mind-bending rabbit hole. But rather than a tunnel of...
Insider Brief PRESS RELEASE — Everything around us, from atoms and molecules to planets and galaxies, is governed by two extraordinarily successful theories of physics: Quantum mec...
