Glasgow University scientists have developed a new dance mimicking ripples of spacetime first theorised by Albert Enstein.

New research is shedding light on what researchers call "lite" intermediate-mass black holes, which are smaller, but still ...

This means LIGO would be able to detect gravitational waves even from merging neutron stars that are about 4 megaparsecs (roughly 13 million light-years) farther away than before.

That tiny time shift, arising from the fact that LIGO's (and Virgo's, and KAGRA's) arms compress by about 0.01% the width of a proton, is presently being used to find dozens of new merger events ...

LIGO-Virgo/Frank Elavsky, Aaron Geller/Northwestern. The LIGO Scientific Collaboration and Virgo Collaboration released a catalog of results from the first half of its third observing run (O3a). This ...

LIGO changed that. Last year, the collaboration announced that its twin detectors had picked up a passing distortion in late 2015 caused by two black holes crashing into each other.

LIGO is based on mirrors separated by kilometers reflecting laser beams back and forth multiple times. And those laser beams are composed of photons that obey the rules of quantum mechanics.

(LIGO was last booted up in November and ran through August.) After the new work is finished in 2018, he said, LIGO should have a 50% boost in range, allowing it to gaze another 500 million light ...

How does LIGO's detection of a second gravitational wave add to what we know about this phenomenon? This question was originally answered on Quora by Shern Ren Tee.

LIGO is called an observatory, but it isn’t like any astronomical observatory you might be imagining. Each site—there are two currently—is actually a big, L-shaped tube called an interferometer.

For 13 years LIGO heard, it seemed, every vibration but the one it was supposed to. But on September 14, 2015 it detected those black-hole-crashing swells as they washed over the planet.

LIGO detected gravitational waves created from the collision between two black holes. The detection was awesome, but let's look at the name of the detector for a second: Laser Interferometer ...
