However, no experiments can be performed that would distinguish these two descriptions. We explain how this could work in practice; a key ingredient is the suggested quantum-chaotic nature of black holes.7 pages, no figuresHigh Energy Physics - TheoryGeneral Relativity and Quantum CosmologyChaotic DynamicsQuantum Physicstext
