Astrowiki/Supermassive Black Hole

From BluWiki

A supermassive Black Hole is a black hole that can be anywhere from 100,000 to 1,000,000,000 times the solar mass of our sun. Hypothetically, there is a supermassive black hole in the center of all spiral galaxies, and in many other types of galaxies as well. Supermassive Black Holes are formed hypothetically when a hypergiant star goes hypernova, causing the core to collapse into a massive black hole. Over billions of years, these hypernova black holes will consume objects around them, causing them to become larger and more massive. That is theoretically how supermassive black holes are formed. There are other theories as well, but this is the one that astrophysicists consider fact for now. There is a supermassive black hole in the center of the Milky Way galaxy, although it is not as active as other ones. The powerful pull of gravity from these giant monsters is enough to hold an entire galaxy around it, which must mean that these are truly monstrous beasts. Although rare, they are a spectacular way of demonstrating the incredible power that gravity can create.
