N. FISCHERH. PFEIFFERA. BUONANNO / AFP It was brief but rich in lessons. On May 21, 2019, three gravitational wave detectors (the two American Ligo and the European Virgo) recorded at the same time or almost a space-time tremor which lasted only a tenth of a second! It is the shortest “space earthquake” recorded to date, but also the one which corresponds to the most energetic event: two black holes of 85 and 66 solar masses have merged to form a new black hole of 142 solar masses, a record (the missing mass corresponds to the energy dissipated in the form of gravitational waves). It is almost twice the mass of the previous record. “We quickly realized that we were dealing with something different ”recalls Nelson Christensen, director of the Artemis laboratory at the Côte d’Azur Observatory. It is also the most distant fusion ever detected, and the signal took 7 billion years to reach us, just over half the age of the Universe. This article is for subscribers only.
