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 ...

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 ...

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 ...

Physicists with the LIGO/Virgo/KAGRA collaboration have detected the gravitational wave signal (dubbed GW231123) of the most massive merger between two black holes yet observed, resulting in a new ...

Scientists have used a gravitational wave detector to "hear" two black holes getting bigger as they merged into a single, gigantic entity. The detection, made by the Laser Interferometer Gravitational ...

Ten years after LIGO’s historical detection of gravitational waves, the project is cracking black hole mysteries at an astounding pace. reading time 4 minutes LIGO’s discovery of gravitational ...
