Gravitational Waves Reveal Lightest Black Hole Ever Observed
sciencehabit shares a report from Science Magazine: Gravitational wave detectors have spotted a cosmic collision in which a giant black hole swallowed up a mystery object seemingly too heavy to be a neutron star, but too light to be a black hole. Weighing in at 2.6 times the mass of the Sun, the object falls into a hypothetical “mass gap,” a…
