What if black holes are Rosetta stones?

摘要

A Quantum makeover means black holes can be described in the two disparate languages of physics - gravity and quantum mechanics. As well as paving the way for a much-sought-after theory of quantum gravity, the idea helps solve some mysteries surrounding these bizarre objects. Black holes are full of puzzles. Theory says they should evaporate and give off heat at a constant temperature, though no one knows why. For some reason, they also get hotter as they shrink.
