There are many strange and fascinating object exist in outer space.Black hole is one of them which is the strangest and most fascinating object in outer space.A black hole is a place in space where gravity pulls so much strong that nothing ,not even light escape their if it comes near enough.A black hole is anything but empty space.Rather ,it is a great amount of matter packed into a very small area.
Albert Einstein First predicted the existence of black holes in 1916,with his general theory of relativity .The term”black hole” was coined(created) many years later in 1967 by american astronomer Jhon Wheller after decades of black holes being known only as theoretical objects,the 1st physical black hole even discovered was spotted in 1971.
Then, in 2019 in event horizon telescope(EHT) collaboration released the first image even recorded of a black hole.The EHT saw the black hole in the center of galaxy M87 while the telescope was examing the event horizon.The image maps sudden loss it photons.It also opens up a whole area of research in black holes ,now that astronomer know what a black hole look like.
Scientists think that black holes are created in places where matter gets extremely dense. This can happen in the centers of large galaxies or when a giant star collapses and shrinks during the final phases of its life. When matter gets so dense that light cannot escape from it, the region that it is in becomes a black hole.
Astronomers have long thought that black holes come just two kinds.one is the “stellar” and other is the “supermassive”.These kinds of black hole depend on the weight of the black hole, more specifically,its mass.
Stellar black hole:the mass of the stellar black hole is so so high than the mass of the sun.
supermassive black hole: the mass of these kind of black hole is almost same of the mass of a galaxy.
Except these,a number of such black holes exist in space.For example,Intermediate black hole,Miniature black hole,Primordial black hole.Stellar black holes are made when the center of a very big star falls in upon itself ,or collapse.When this happens,it causes a supernova.A supernova is an exploding star that blasts part of the star into space.scientists think supermassive black holes were made at the same time as the galaxy they are in.
