Black Hole

The space is amazingly mysterious and black holes are one among such mysteries. Interested to know about black holes? Visit our basic post on black holes here. Astronomers believe that the space has three different types of black holes. The differentiation is based on their mass.

The three types of black holes include Stellar Black Holes, Supermassive Black Holes, and Miniature Black Holes. It is also believed that these black holes would have formed due to different causes and in different ways. There is also another division of black holes where scientists classified them into those which spin and those which don’t.

Stellar Black Holes: When smaller stars burns out all its fuel, the new core of the star will be a neutron star. These smaller stars can be up to three times the size of our Sun in their mass. But when a larger star dies off, it develops an unstable situation. Its outer layers explode into a supernova while the inner part implodes. The collapse of such a larger star ultimately creates a stellar black hole. Astronomers believe that there are a few hundred million stellar black holes in the Milky Way.

Supermassive Black Holes: The origin of supermassive black holes may be due to the merging of hundreds and thousands of tiny black holes. The supermassive black holes’ origin could also be due to the collapse of a dense cluster of stars. The theory says that every galaxy has a supermassive black hole in its center. This is applicable to our Milky Way too.

It is now good to learn about the event horizon. It is an imaginary sphere around a black hole. The escape velocity at the event horizon is greater than the speed of light. This means, if anything crosses this sphere, it won’t be able to escape from it, even if it is light.

Miniature Black Holes: These black holes might have existed since the big Bang. They are much smaller than the Sun. During the early stages of our Universe, after the Big Bang, the rapid expansion of space might have squeezed some slower moving matter. This could have caused the formation of Miniature Black Holes.
