Hey guys we are here for knowing what is the black hole and facts, theory and definition. As be know NASA share with us what's they searching and what's they found. A black hole is anything but empty space. Scientists can't directly observe black with telescopes that detect x-rays, light, or other forms of electromagnetic radiation.
Black holes are some of the strangest and most fascinating objects found in outer space. They are objects of extreme density, with such strong gravitational attraction that even light cannot escape from their grasp if it comes near enough.
Albert Einstein first predicted black holes in 1916 with his general theory of relativity. The term "black hole" was coined in 1967 by American astronomer John Wheeler, and the first one was discovered in 1971. There are three types: stellar black holes, supermassive black holes and intermediate black holes.
