The concept of black hole has a recurring use in the field of Astronomy and is used to designate that region belonging to space, with finite characteristics and in which, inside, a high mass is concentrated, capable of generating a gravity field in which no particle material problems, including light, can escape from the the .
The gravitational field is a type of field in which the forces of gravity are represented. It should be noted that this region is capable of emitting radiation.
The aforementioned gravity generates a very particular issue known as the event horizon . The event horizon, also known as the event horizon, consists of a hyper-surface border of space and time in which the events that occur on one side of it can never affect an observer who is on the opposite side.
The British physicist and scientist Stephen William Hawking was one of those who has contributed most to the matter of the space-time singularity and was also the first to speak of the emission of radiation in the black hole. He has even written a book , which was published in 1988, History of Time: from the Big Bang to black holes , which precisely addresses the issue of the formation of black holes in detail . For example, whoever wants to know more in detail about this topic can resort to this text .
According to studies carried out by Hawking and other scientists, it is believed that in a large part of the galaxies, including the Milky Way , there are black holes.
Meanwhile, regarding its origin, it is considered that the black hole is the result of a gravitational collapse that begins after the death or exit of energy , of a red giant , as a star of enormous mass is designated. .
After millions of years of life, the gravitational force of this huge star will exert a lot of force on itself that will cause a very concentrated mass and will become a white dwarf , as the body that depletes its energy is called. Meanwhile, in this phase collapse is possible and this dwarf becomes the aforementioned black hole.
