Researchers report a significant advance in quantum squeezing, which allows them to measure undulations in space-time across the entire range of gravitational frequencies detected by LIGO. In 2015, ...

Researchers have built a small but powerful detector to find gravitational waves in a hidden frequency range. The discovery ...

Gravitational waves, tiny ripples in spacetime caused by cosmic collisions like merging black holes, are almost impossibly faint. Detecting them requires LIGO (Laser Interferometer Gravitational-Wave ...

A strange chirp detected by LIGO in 2019 has some scientists searching for answers beyond a simple black hole merger.

Gravitational wave facilities measure distortions in the fabric of spacetime down to 10 quadrillionths the width of a hair – small enough to hear interference from particles popping in and out of ...

After three years of downtime for crucial upgrades, the world’s gravitational-wave observatories were supposed to restart, more sensitive than ever to the tiniest deformations in spacetime. But ...

After a three-year hiatus, scientists in the U.S. have just turned on detectors capable of measuring gravitational waves—tiny ripples in space itself that travel through the universe. Unlike light ...

New mirror coatings will increase the volume of space LIGO can probe in its next run. Since LIGO's groundbreaking detection, in 2015, of gravitational waves produced by a pair of colliding black holes ...

When incredibly massive objects collide violently in space, they send out ripples in space-time that reverberate through the cosmos for billions of years. Long after the collisions happen, these ...
