New research to illuminate the information encoding in quantum gravity
The discovery of gravitational waves emanating from merging black holes was a spectacular confirmation of Einstein’s general theory of relativity. However, physicists are still puzzled about the role of quantum mechanics as encapsulated by the black hole information paradox. When black holes radiate a small amount of heat (Hawking radiation), they lose mass in the process and ultimately evaporate. During evaporation, information must escape the black hole to avoid violating a central principle of quantum mechanics. The EU-funded HoloHair project aims to shed light on how black holes encode, store and emit information and whether information in quantum gravity in asymptotically flat spacetime is encoded via a holographic principle.
