The black holes are what God mentioned in his holy book, "I shall not swear by the arrogance of the priests." They are the space monsters devouring any energy or mass located in the field of their attractiveness. Is a very large block located in a space or a very small size, which represents the star of the mass of the largest 10 times the sun in the sphere of circular diameter of New York City. It produces a field of gravity so strong that the light itself can not escape it.
.
The black hole results from the death of the stars as the stars have a lifetime that glows after them cool or even explode under the influence of its enormous attractiveness, which occurs in the stars, which are three times larger than the sun or the result of the explosion of two stars and turn into dust and waves hovering in space and keep the heart.
Black holes and the black hole, which explained Einstein's existence of general relativity The black hole can not be observed by ordinary telescopes, which detect X-ray or light, but it is detected by the impact of any star nearby we can see it torn towards him in a circular motion and the faster the closer From the moment the star collides with the black hole, many of the radiation and waves that are detected on the ground and from the satellites are produced. It also produces gases that revolve around it and rise in temperature very much.
Recently discovered that the black holes while absorbing energy around them emit gamma rays with tremendous force pushing more stars nearby and also help to form new stars in other observatories.
Black holes are the centers of galaxies and these holes are very massive mass and equal mass of 4 million stars and our Milky Way galaxy, which contains our solar system has its central black hole also and was observed from the amount of radiation that spews from sucking around it and all absorbed by the black hole becomes part of it and help him To grow up
