Using luminosity measurements, he determined how much mass should be in the cluster and then, because mass and gravity are related, calculated how fast the galaxies should be moving. When he measured their actual velocities, however, he found that the galaxies were moving much, much faster than...
Black holeshave two fundamental properties: their mass (how much they weigh) and their spin (how quickly they rotate). Determining either of these two values tells scientists a great deal about any black hole and how it behaves. The Spin Measurement Technique ...
