LIGO offers clues to black hole physics

About 900 million years ago, there was a collision between a black hole and another compact object which resulted in gravitational waves being spewed out into space. The LIGO and VIRGO collaborations which look for gravitational waves emanating from such events have picked up this signal. Astrophysicists are keenly analysing this signal, as it could signify new insights into black hole physics or hold promise for developing gravitational wave astronomy.
