Black holes give off radiation
Web1 day ago · In 1974, Stephen Hawking discovered that black holes emit radiation. This radiation is called Hawking radiation, and it is caused by the quantum fluctuations of the vacuum near the black hole. Hawking radiation is very weak, and it would take trillions of years for a black hole to evaporate completely. However, the Hawking radiation is a … WebFeb 3, 2024 · Black holes get the energy to radiate Hawking radiation from their rest mass energy. So if a black hole is not accreting mass from outside, it will lose mass by Hawking radiation, and will eventually evaporate. For astronomical black holes, the evaporation time is prodigiously long — about \(10^{61}\) times the age of the Universe

WebApr 12, 2024 · A black hole is a a place where gravity pulls so much in that even light can’t escape, making that area seem black. Since scientists can’t see them, they spot black holes by studying how gravity affects the stars and gas around the black hole. When specifically a black hole and a star are close together, a high-energy light is made.
