Black hole blast emits energy wave eight times bigger than the Sun

A “massive gravitational wave source” from two black holes merging produced a blast equal to the energy of eight suns and sent shockwaves through the universe, scientists have discovered.

Teams from the National Science Foundation’s Laser Interferometry Gravitational-wave Observatory (Ligo) in America, and the Virgo detector in Italy, have released a paper on the cosmic phenomena.
