What is the origin of black hole entropy? • Does black hole evaporation lose information? Does it violate quantum mechanics? Hawking argued for three decades ... Weighing in at hundreds to a billion times more massive than our Sun, these giant black holes grow at an alarming and seemingly impossible rate. In fact, the ... May 6, 2020 ... This artist's impression shows the orbits of the three objects in the HR 6819 triple system: an inner binary with one star (orbit in blue) and a ... Abstract. One of the attractive solutions to the information loss problem is that the event horizon does not appear in the process of gravitational collaps. Apr 1, 2023 ... A sketchy review of the "island" paradigm in black hole evaporation theory, which actually brings us back to the old idea that interior of black hole decouples ...
