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.

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 … WebJul 9, 2024 · Instead, black holes are decaying, and losing mass over time, because the energy emitted by this Hawking radiation is slowly reducing the curvature of space in … gateway church king\u0027s lynn https://theeowencook.com
