The black hole (black hole or cavity black) is a region of spacetime that gravitational field prevents everything, including light also could not escape. [1] [2] the theory predicts a physical volume with sufficient mass in the range small enough will deform spacetime to become black holes. Around the black hole is a surface defined by a mathematical equation called the event horizon, at which material pass when it will not be able to escape the black hole. The black hole called "black" because it absorbs all the radiation and matter-through the event horizon, like a blackbody in thermodynamics; It also is not a kind of "hole" or "pit" which is not the time not to let something escape. [3] [4] quantum field theory in curved spacetime predicted at the event horizon of black holes have played out like the black body radiation has the given temperature emit thermal radiation. This temperature is inversely proportional to the mass of the black hole, making it very difficult to observe this radiation towards the black hole has a mass of stars or average.
