On the passing of the test act in 1681 he refused to take the required oath except with a reservation.
Located in the Coma Cluster, about 300 million light years away from Earth, the orb is actually a distant view of the giant elliptical galaxy NGC 4889. At the center of that galaxy lies a sleeping giant: a supermassive black hole that is 21 billion times the mass of our sun. The size of a black hole can be estimated by its event horizon, or the distance from the center of the black hole at which nothing can escape its gravitational grasp.
Black holes pull matter and even energy into themselvesâbut no more so than other stars or cosmic objects of similar mass. That means that a black hole with the mass of our own sun would not suck objects into it any more than our own sun does with its own gravitational pull.Planets, light, and other matter must pass close to a black hole in order to be pulled into its grasp.xtremely large black holes may exist at the center of some galaxiesâincluding our own Milky Way. These massive features may have the mass of 10 to 100 billion suns. They are similar to smaller black holes but grow to enormous size because there is so much matter in the center of the galaxy for them to add.
