This week I was interested in black holes and therefore I researched about this topic. Many people think that they know about black holes just because they know that it has a very strong pull and nothing can escape from it. However this doesn’t even graze the surface as it is a very, very brief definition.
Firstly, black holes come in three different types: stellar black holes, supermassive black holes and intermediate black holes. Stellar black holes are formed when a star burns through the last of its fuel. If this star is below approximately 3 times as big as our sun, which is relatively small for a star, then the core will just become a neutrino star or a white dwarf. However, if it is a larger star, then the star collapses in on itself and creates a black hole with its giant amount of gravitational force. They can grow in size by gathering dust and gas from the surrounding space.
The next type is a supermassive black hole, which is millions or even billions of times larger than the sun. These types of galaxies lie in the middle of almost every galaxy, including the Milky Way. The cause of this type of black hole is unknown to scientists as of now. At the centre of galaxies there is plenty of dust and gas available, which allows these black holes to grow colossal.
And finally there is an intermediate black hole. These black holes are medium in size compared to the small stellar black holes and the giant supermassive black holes. They are created when a star in a cluster collide in a chain reaction. Some scientists say that if a few of them form in the same area, then they may be able to collapse into one another and form a supermassive black hole.
I will continue further with black holes next week as I cannot fit it all in today. See you next week!
