Summary

LIGO observed a transient waveform from a binary-black-hole merger in 2015, the first direct detection of gravitational waves and a strong-field test of general relativity.

Binary black-hole systemGW150914 gravitational-wave detection

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

GW150914 matched a binary-black-hole inspiral, merger, and ringdown waveform.

How to interpret this relation type

The source theory, law, entity, prediction, or structural claim is directly tested, supported, constrained, or established by the target experiment or observation. Experimental support is not final logical proof; the edge detail states exactly what was measured.

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

The signal’s inspiral, merger, and ringdown were consistent with numerical general-relativistic predictions.

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

LIGO measured the strain waveform from a binary-black-hole coalescence, directly detecting gravitational waves and matching a general-relativistic inspiral–merger–ringdown signal.
