Experimental confirmation and conceptual resolution of Hawking radiation

Demonstrate experimentally the existence of Hawking radiation from black holes and resolve the outstanding conceptual issues associated with black hole evaporation, including the consistency of the process with quantum mechanics and thermodynamics.

Background

Hawking’s prediction that black holes emit thermal radiation with temperature inversely proportional to their mass revolutionized theoretical physics by connecting general relativity, quantum mechanics, and thermodynamics. This radiation implies black hole evaporation on mass-dependent timescales.

The authors emphasize that, despite intense theoretical and experimental efforts, Hawking radiation has not yet been observed and key conceptual puzzles remain. Confirming the phenomenon and addressing its conceptual foundations (e.g., information flow, backreaction, and endpoint of evaporation) are central unresolved issues.
