The third explosion has been reported as the loudest sound in history. [6] [7] [8]: 602 [4]: 79 The loudness of the blast heard 160 km (100 mi) from the volcano has been calculated to have been 180 dB. [9] Each explosion was accompanied by tsunamis estimated to have been over 30 metres (98 feet) high in places.
In June 2020, astronomers reported details of a compact binary merging, in the "mass gap" of cosmic collisions, of a first-ever 2.50–2.67 M ☉ "mystery object", either an extremely heavy neutron star (that was theorized not to exist) or a too-light black hole, with a 22.2–24.3 M ☉ black hole, that was detected as the gravitational wave GW190814.
Known gravitational wave events come from the merger of two black holes (BH), two neutron stars (NS), or a black hole and a neutron star (BHNS). [ 9 ] [ 10 ] Some objects are in the mass gap between the largest predicted neutron star masses ( Tolman–Oppenheimer–Volkoff limit ) and the smallest known black holes.
The post This is the loudest recorded sound in the history of Earth appeared first on BGR. To call sound an important part of human life would be an understatement. It’s so important, that MIT ...
The inferred fundamental properties, mass and spin, of the post-merger black hole were consistent with those of the two pre-merger black holes, following the predictions of general relativity. [ 7 ] [ 8 ] [ 9 ] This is the first test of general relativity in the very strong-field regime .

GW190521 is a significant discovery due to the masses of the resulting large black hole and of one or both of the smaller constituent black holes. Stellar evolution theory predicts that a star cannot collapse itself into a black hole of more than about 65 M ☉, leaving a black hole mass gap above 65 M ☉. The 85 +21 −14 M ☉ [note 3] and ...
