Gravitational waves have been picked up from the biggest black hole merger yet detected.
Scientists say their laser labs sensed the ripples in space-time emanating from this gargantuan collision on 29 July 2017.
The event saw two holes, weighing more than 50 and 34 times the mass of our Sun, uniting to produce a single object over 80 times the mass of our star.
It happened at least five billion light-years from Earth.
=============================================
Fascinating development in astrophysics. I'm intrigued by their ability to detect gravitational waves from such a huge distance.
The existence of these waves was postulated by Einstein in 1916.

The detection method is called laser interferometry.
