A black hole is a region in space with a tremendous gravitational field. It is called black because even light cannot scape from it. In the 70s Professor Hawking predicted that there is black-body radiation emitted from the black hole. The detection of this kind of radiation was almost impossible due to two main factors: first of all the radiation is very delicate, which makes it difficult to observe. Secondly, it is so far away that the distance could probably debilitate the signal.
Of course to prove it in the lab was not feasible, until a group of scientist in Israel had the idea to use ultracold Helium. Some other ideas are also starting to flourish. Will Hawking Radiation be proven in the lab? Click on the image below to know more, and also HERE.
