LIGO has detected gravitational waves, or ripples in Einstein's spacetime. But can it go deeper, and probe the quantum nature of gravity itself?

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.

Forget telescopes. This observatory, built to feel rather than see, aims to find gravitational waves, possible clues to the universe's dark side.

LIGO's announcements earlier this year gave the scientific community a celebratory jolt, as the first and second gravitational wave events from merging black holes were unambiguously detected.

An international collaboration of scientists, the LIGO Scientific Collaboration, has announced the first detection of gravitational waves, ripples in the fabric of space and time that carry ...

Gravity wave telescopes will allow us to observe directly entirely new phenomena that have been inaccessible to us previously.” “We can now study black holes and other violent events in our universe — ...

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.

So the two LIGO facilities use a laser beam to try to deduce the passing of a gravitational wave. The beam is split in two, with each part bouncing off mirrors perched at the end of perpendicular ...

Patrick Brady, Professor of Physics at UW-Milwaukee, talks about LIGO, the Laser Interferometer Gravitational-Wave Observatory, which observed and measured the gravitational waves created by a ...
