The Einstein Telescope would also be a laser interferometer but with much longer arms. While LIGO has arms four km long, ...

The study authors propose that the Laser Interferometer Gravitational-Wave Observatory (LIGO) has the potential to detect ...

The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a huge installation measured in kilometers that is listening for wrinkles in space-time. Pulling this off is a true story of ...

This black hole merger animation was created using data collected by the LIGO and Virgo gravitational wave detectors, an ...

A team of researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO), in the U.S., has developed what they describe as a squeezed light system to improve detection sensitivity.

A pivotal week in Corey Gray's life began with a powwow in Alberta and culminated with a piece of history: The first-ever ...

But he was proved both right and wrong 100 years later, when an international team detected them for the first time using a pair of 4km-long L-shaped machines called Advanced LIGO. Pallab Ghosh ...

When black holes merge, what happens inside of them is anybody's guess. Black hole mergers are beautiful — and some of the most violent events in the cosmos. Here's how the process unfolds.

The best-fit models of LIGO's gravitational-wave signals are converted into sounds. The first sound is from modeled gravitational waves detected by LIGO on Dec. 26, 2015, when two black holes merged.

When Dawn Hauser asked the students gathered inside the Reynolds Elementary School’s gymnasium who liked adventure, every ...

Gravitational waves carry a lot of information, which we measure with detectors like LIGO and Virgo. Unfortunately, gravity is by far the weakest force, so the speed of gravity hasn’t yet been ...
