Summary:

- Black holes are known to emit a faint glow of radiation, known as Hawking radiation, which causes them to gradually lose mass and eventually evaporate over an incredibly long time.
- The existence of Hawking radiation has been indirectly confirmed through various observations and experiments, providing strong evidence that black holes do indeed evaporate.
- Understanding the physics of black hole evaporation is an important area of research in quantum gravity, as it could help reconcile the apparent contradiction between the information loss paradox and the principles of quantum mechanics.
