What is a black hole?
A black hole is a region in space where gravity is so strong that not even light is able to escape.
The gravity coming from a black hole is the result of matter being compressed into a tiny place.
Black holes are mainly divided into 3 types:
1. Firstly, Primordial black holes are the smallest type of black holes in the universe. Scientists believe this type of black hole is as small as a single atom but are as massive as a large mountain.
2. Secondly, Stellar black holes are the most common type of black holes in the universe. The mass of a stellar black hole can be up to 20 times greater than the mass of the sun and can fit inside a space of about 10 miles.
3. And finally, The largest type of black holes, Supermassive black holes are over a million times more massive than our sun and would fit inside a space about the size of the solar system. These supermassive black holes are found within large galaxies such as the Milky Way.
So, how do Black holes form?
Primordial black holes are thought to have formed in the early universe, soon after the big bang.
Stellar black holes form when the center of a very massive star collapses in upon itself. This collapse also causes a supernova that blasts part of the star into space.
Scientists think supermassive black holes formed at the same time as the galaxy they are in. The size of the supermassive black hole is related to the size and mass of the galaxy it is in.
Now, How do we know they exist?
The presence of a black hole can be inferred through its interaction with other matter and with electromagnetic radiation such as visible light. If there are other stars orbiting a black hole, their orbits can be used to determine the black hole's mass and location.
