The National Science Foundation’s LIGO (Laser Interferometer Gravitational-Wave Observatory) is set to resume its hunt for gravitational waves — ripples in space and time — on April 1, after receiving ...

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, ...

Gravitational-wave astronomy is growing up. These ripples in the fabric of space-time are created by accelerating masses, which then travel outward from their origin at the speed of light. While ...

LIGO, the Laser Interferometer Gravitational-wave Observatory, has been called the most precise ruler in the world for its ability to measure motions more than 10,000 times smaller than the width of a ...

PASADENA, Calif.– The search for gravitational waves has revealed new information about the core of one of the most famous objects in the sky: the Crab Pulsar in the Crab Nebula. An analysis by the ...

Could LIGO find alien spacecraft accelerating to near light speed? The gravitational wave detector LIGO has made hugely important discoveries. But what else might be hiding in the ripples’ of ...

After a whirlwind tour of press conferences, parties and awards following their Feb. 11 announcement of the world’s first direct detection of gravitational waves, the team of scientists at the Laser ...
