Definition of black hole

The concept of black hole has a job recurrent in the field of Astronomy and is used to designate that region belonging to space, with finite characteristics and in which, inside it, a high mass is concentrated, capable of generating a field of gravity in which no particle of a material nature, including light, may escape from thethe.

The gravitational field It 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 that is known as event horizon. The event horizon, also known as the event horizon, consists of a hyper surface of border of space and time in which the events that take place on one side of it can never affect an observer who is on the other side.

The British physicist and scientist Stephen William Hawking He was one of those who has contributed the most to this issue of spacetime singularity and also he was the first to talk about 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 training of black holes. For example, anyone who 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 good part of the galaxies, including the Milky Way, there are black holes.

Meanwhile, as far as its origin, it is considered that the black hole is the result of a gravitational collapse that begins after the death or exit of the Energy, of a red giant, as designated a star of a huge mass.
After millions of years of life the force 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 exhausts its energy is called. Meanwhile, in this phase collapse is possible and this dwarf becomes the aforementioned black hole.
