Whose experiment first detected gravitational waves from colliding black holes?
Quick Answer
The LIGO team announced the first direct detection in 2016. The waves came from a merger about 1.3 billion light-years away.
The Full Story
The Laser Interferometer Gravitational-Wave Observatory, or LIGO, reported the first direct detection of gravitational waves in 2016. The signal came from two colliding black holes about 1.3 billion light-years from Earth. This confirmed a major prediction of Einstein’s general relativity made a century earlier. The discovery opened a new era of gravitational-wave astronomy and won the 2017 Nobel Prize in Physics for key contributors.
