Recently, we all should know that scientists estimate that Black Holes will end and will take much much much much much time than the life time of the Universe!!!!!!! Stephen Hawking theorized that Black Holes emit radiation known as "Hawking Radiation". Due to radiation, Black Holes will slowly evaporate. But there is a research going on the theory that on Earth, there is a black hole which absorbs sound. Applying the theory to this will lead to leak of sound having very low intensity. If it is true, then Black Holes should emit "Hawking Radiation".
