Researchers at the Swedish Royal Institute of Technology believe they have found a way to create a black hole on Earth. Black holes are bodies of very high mass density space and the gravitational field due to density is so large that light can not escape its attraction. Black holes can't be seen directly, but can detect them because of the perturbations they generate around them. Swedish researchers want to create a black hole in the lab to check if Hawkins' supposedly fugable radiation is real. But they do not want to form a real black hole, but an optical black hole, that is, a black hole that absorbs light and not matter. They want to make the light that moves very slowly into a whirlpool, as the light would fall into the black hole. For this purpose they will use the matter in state Bose-Einsten as means of transport of light. In Bose-Einstein state the matter is very cold and the light moves to 50 cm/s. If the speed drops to 1 cm/s, Swedish researchers could be in a position to make the aforementioned optical black hole
