Today the international collaboration of LIGO ,which deals with evidence of general relativity predicting gravitational waves, officially announced the completion of the merger of two black holes in 29 and 36 solar masses at a distance of 1.3 billion light years from Earth.

The LIGO detector managed to fix gravitational waves generated by their merger. Up to three solar masses were involved in the creation of these massive space objects.
