This a process similar to auto-tune used in music production – where software can correct a singer’s pitch if it is off key to meet the right note.
The research was carried out by a team from the International Ligo, Virgo and Kagra (LVK) gravitational wave observatory collaboration – a network of scientists who co-ordinate and collaborate on the operation of the detectors and the scientific results.
They made their discovery while tracing signals produced by the collision of two black holes between 35 and 30 times the mass of our sun, about 600 million light-years from Earth.
The team have said that the gravitational-wave signals produced are among the loudest they’ve ever detected.
