The next Figure shows a black hole. Essentially,it is a region of space within which the subject dropped, and nothing can escape, inside a black hole gravity is so powerful that not even light can move out. The term "black" is highly appropriate, because if even light can emerge from within a black hole, it must be an entity entirely black, the term "hole" is also appropriate, since unlimited amounts of matter or energy can fall into it, and in this sense it is like a bottomless pit. (Adapted from NICOLSON , 1981, p. 129) Much of Physics Astronomy was born of a need put the great voyages. Were the observations of celestial bodies that led to the work of Galileo, Copernicus, Kepler, Tycho, Newton and others. But at the end of the last century, the path is reversed, and were advances in theoretical physics that allowed the development in the areas of astrophysics and cosmology. The theory of gravitation Einstein was able to predict the deviation of light from some stars passing near the Sun According to Einstein's theory, this deviation is not caused by the force of attraction, but as the space around the Sun is deformed the only ray of light follows the curvature exists. The experimental confirmation that the universe is curved only been possible in 1987. According Hallyday (1994), doing a retrospective on gravitation, the studies of Galileo, Newton's theory and Einstein which provides two possibilities for the future, the infinite expanse of the universe to a certain limit and then the contraction of the same to return to the initial state, the history of gravitation is far from ending. Remember our initial question? Will now you cananswer it? Apparently, when passing by a very strong gravitational field, the light has changed its trajectory. Exist a gravitational field strong enough to the point ofimprisoning her?

Sljedeća slika prikazuje crnu rupu. U osnovi,to je regija u prostoru u kojem je predmet pao, i ništa ne može pobjeći, unutar crne rupe gravitacije je toliko moćan da čak ni svjetlost može iseliti. Pojam "crno" je vrlo prikladno, jer ako ni svjetlo može izaći iz crna rupa, ona mora biti subjekt u potpunosti crna, pojam "rupa" je i primjereno, jer neograničene količine materije ili energije može u nju pada, au tom smislu je kao Bezdana. (preuzeto iz Nicolson , 1981, str. 129) Velik dio fizike astronomije rođen od potrebe staviti velike putovanjima. Jesu promatranja nebeskih tijela koja su dovela do rada Galileo, Kopernik, Kepler, Tycho, Newton i drugi. No, krajem prošlog stoljeća, put je obrnut, te su napredak u teorijskoj fizici koja je omogućila razvoj u područjima astrofizike i kozmologije. Teorija gravitacije Einstein je bio u stanju predvidjeti odstupanje svjetlosti od nekih zvijezda koje prolaze u blizini Sunca Prema Einsteinovoj teoriji, ova devijacija nije uzrokovana silom privlačnosti, nego kao prostor oko Sunca deformirana samo tračak svjetlosti slijedi zakrivljenost postoji. Eksperimentalna potvrda da je svemir zakrivljen bio moguć samo u 1987. Prema Hallyday (1994), radi retrospektivu o gravitaciji, studij Galileo, Newtonova teorija gravitacije i Einstein, koji nudi dvije mogućnosti za budućnost, beskrajna prostranstva svemira do određene granice, a zatim kontrakcija isti vratiti u početno stanje, povijest gravitacije je daleko od završetka. Zapamtite naše početno pitanje? Hoće li sada možeteodgovoriti na to? Navodno, kada je prolazio vrlo jakom gravitacijskom polju, svjetlost se promijenila putanju. Izlazna gravitacijsko polje dovoljno jak do točkeju zatvaranjem?
