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 hole theory â how they tick. Black holes are incredibly massive, but cover only a small region. Because of the relationship between mass and gravity, this means they have an extremely powerful gravitational force. Virtually nothing can escape from them â under classical physics, even light is trapped by a black hole.
