The Binary Black Hole Grand Challenge Alliance (BBH Challenge Alliance) was a scientific collaboration of international physics institutes and research groups dedicated to simulating the sources and predicting the waveforms for
gravitational waves
Gravitational waves are oscillations of the gravitational field that travel through space at the speed of light; they are generated by the relative motion of gravitating masses. They were proposed by Oliver Heaviside in 1893 and then later by H ...
, in anticipation of gravitational radiation experiments such as
LIGO
The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a large-scale physics experiment and observatory designed to detect cosmic gravitational waves and to develop gravitational-wave observations as an astronomical tool. Prior to LIG ...

History
The BBH Challenge Alliance was established in 1993. This was an alliance of numerical relativity groups engaged in a friendly competition to tackle the grand challenge of simulating binary black hole collisions for the purpose of understanding gravitational wave signatures that would be detected by experiments such as LIGO.
