Summary:
- The article discusses a new experiment that has observed a long-predicted quantum phenomenon called Hawking radiation, which is emitted from the event horizon of black holes.
- The experiment used an analog system involving a flowing fluid to simulate the conditions around a black hole, and was able to detect the thermal radiation that is predicted to be emitted.
- This observation provides experimental validation of Hawking's 1974 prediction, which was a major breakthrough in our understanding of black hole physics and the relationship between quantum mechanics and general relativity.
