When two massive objects – like black holes or neutron stars – merge, they warp space and time. Mark Garlick/Science Photo Library via Getty Images After a three-year hiatus, scientists in the U.S.

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 ...

Scientists may have "heard" the first tantalizing evidence of primordial black holes formed directly from overly dense ...

Gravitational waves are caused by cosmic events like colliding black holes or neutron stars, explosive supernovas and even the birth of the universe. The waves travel across the universe at the speed ...

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 ...

On May 24, scientists at the Laser Interferometer Gravitational-Wave Observatory (LIGO) began an 18-month campaign to detect the most distant collisions between black holes and neutron stars ever ...

The LIGO project's gravitational-wave detector facility in Livingston, Louisiana. Seven years ago, researchers with the Laser Interferometer Gravitational-Wave Observatory (LIGO) reported the first ...

Earth is awash in gravitational waves. Over a six-month period, scientists captured a bounty of 39 sets of gravitational waves. The waves, which stretch and squeeze the fabric of spacetime, were ...

The 2017 Nobel Prize in Physics was awarded Tuesday morning to three pioneers of the Laser Interferometer Gravitational-wave Observatory, which announced last year the world's first direct detection ...

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 ...

Seven years ago, researchers with the Laser Interferometer Gravitational-Wave Observatory (LIGO) reported the first detection of gravitational waves. Now, the list of gravitational wave candidates ...
