Black holes are often thought of as dark holes sucking matter in towards them by there massive amount of gravitational force. Interestingly enough, however, black holes are anything but black. Black holes might be dark, but they glow. It is well known that black holes decay until they don't have enough energy to sustain their mass, thereby not allowing them to exist any longer. But what does this loss of energy turn into? The slight glow in black holes. This slight glow is due to "Hawking Radiation". It is the slight decay of energy into radiation from black holes over the time of their existence. It is intriguing all the unknown facts about the universe and how much more is left to be discovered!
