Gravitational wave detectors capture their most massive black hole merger to date – BBC Focus Magazine
The collision was more of a ‘bang’ than a ‘chirp’.
An international team of astronomers working at the LIGO and Virgo gravitational wave detectors have made their biggest discovery yet: the collision of two black holes that merged together to create a black hole around 142 times the mass of the Sun the biggest ever detected using gravitational waves.
The merger has several unusual features and could lead to the discovery of new physics, they say.
The collision occurred 7 billion years ago when the two black holes began spiralling into one anot…
