For 13 years, the scientists of LIGO—the most ambitious, and expensive, project in the history of the National Science Foundation—had been waiting. LIGO, the Laser Interferometer Gravitational-Wave ...

A century after Albert Einstein rewrote our understanding of space and time, physicists have confirmed one of the most elusive predictions of his general theory of relativity. In another galaxy, a ...

Scientists on the lookout for subtle disturbances in the fabric of space-time have detected the signal from a cataclysmic collision between two black holes that lie some 3 billion light-years away, ...

The Laser Interferometer Gravitational-wave Observatory (LIGO) just detected gravitational waves, ripples in time and space, for the third time. Two black holes collided, forming a huge black hole 49 ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. When the Advanced Laser Interferometer Gravitational-Wave ...

Putting the squeeze on light improves gravitational wave observatories. An upgrade to one such observatory, LIGO, that comes from exploiting a quantum rule known as the Heisenberg uncertainty ...

Physicists have detected the biggest ever merger of colliding black holes. The discovery has major implications for researchers’ understanding of how such bodies grow in the Universe. “It’s super ...

Certain detection of gravitational waves requires at least two detectors located at widely separated sites. Regional phenomena such as micro-earthquakes, acoustic noise, and laser fluctuations can ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. On September 14th, 2015, less than 72 hours after it began operation at ...

On September 14, 2015, a signal arrived on Earth, carrying information about a pair of remote black holes that had spiraled together and merged. The signal had traveled about 1.3 billion years to ...

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 ...
