matter how unfortunate it may sound, but today many completely wrong or at best a vague idea of what a black hole.And there are objects in the universe a lot.And they are so powerful and global, that our planet and our whole life, even in comparison with them - nothing.
scientific theories predicted the mass of the hypothetical objects that exist in the universe.And none of them does not make such a terrible impression, like a black hole.Speculation about their education, essence and existence in general have been made a long time ago.Before it published Einstein's relativity theory.
But only recently have been obtained fairly compelling evidence that black holes in the universe do exist.After all, according to the theory of relativity it is such formations are quite possible, but over the years refuted even the possibility of predicting the formation of such objects.
According to studies, the black holes are so characteristic of a great gravity, they absorb everything that gets in their limits.But there is a more specific definition of what is a black hole.At its core, it is an object that is not producing the light and bends space and time.
very interesting is the fact that even close to these structures, time flows more slowly.Ample study of these objects is, unfortunately, impossible.There are only a mass of assumptions and a number of practical developments.Therefore, all the objects that fit this description are called black holes, leaving a huge number of questions unresolved.
It should also be noted that any black hole has its own event horizon - the border, after crossing which will not be able to get out.Moreover, the object as it approaches the hole begins to move much more slowly.
Of particular interest is a discussion of how black holes are formed.Today, it is assumed that there are three basic ways of their formation:
- As a result of the formation of the universe.This type of black holes appeared immediately after the Big Bang.
- dying star.After the star loses its own energy - stop thermonuclear reactions, causing it to gradually shrink.From the extent of the compression depends on the object type: white dwarfs, neutron stars and black holes themselves.
- With experiment.For example, in the collider might create a kind of quantum black hole.
There is also a lot of theories about what a black hole is and what it is.So, many scientists are of the opinion that these facilities emit absorbed all of the matter in any other place.Following such approval, there should be operating on the opposite principle of "white" hole.
Simply put, if the black hole gets everything, but nothing is chosen, the white, on the contrary, it is impossible to get there.The main argument of scientists are fixed in space, powerful and sharp bursts of energy.
remains very popular and string theory, which advocates created its own model of a black hole in which the information is not destroyed.This makes it possible to answer several questions related to the singularity - a point in space, characterized by infinite density and pressure.
But many are skeptical that the fact that the singularity will provide an opportunity to examine exactly what the black hole physics as an infinite number of work can not.Therefore, even though the existence of such a point recognized directly in the object, but the property it describes very superficially.
should still pay tribute to such intriguing formation in the universe.After all, up until now a black hole - it is one of the most mysterious and interesting objects.Scientists have just found exactly what their emergence occurs as the result of a very strong contraction of a mass of Noah, after which increases the attraction is so powerful that it is not produced neither light nor any other radiation, no body, no signals.Therefore, yet to learn a lot of entertaining.
