1+ week, 4+ day ago  (212+ words) Why are black holes heavier than 45 solar masses so rare? Project lead, Tong, explained that the team's analysis of gravitational wave signals " the ripples in the fabric of spacetime " detected by the LIGO-Virgo-KAGRA observatory afforded evidence of the existence of…...

14+ hour, 5+ min ago  (813+ words) The clearest evidence yet of a missing band of black-hole masses has emerged, with the gap beginning near 45 times the Sun's mass. The research sharpens a long-running mystery about how the biggest stellar black holes form and why some of…...
