Merging black holes Illustration of two black holes spiralling around each other in a nonaligned fashion along an orbital plane It is thought a system like this produced the gravitational waves of the GW signal detection of January The mergers of black holes cause gravitational waves a prediction of Einsteins theory of general relativity The effect is most pronounced where extremely massive objects black holes or neutrons stars are subject to extremely high acceleration In February gravitational waves were detected for the first time years after Einsteins prediction The waves were detected by the LIGO detectors in the USALigoCaltechMitSonoma State Aurore SimonnetScience Photo Library
