Webradiation [9, 10]. Once he found that the radiation had a thermal spectrum, he realized that it did make Bekenstein’s idea consistent, of a finite black hole entropy proportional to area, though not Bekenstein’s conjectured value for η. In fact, Hawking found that the black hole temperature was T = κ/(2π), so ǫ = 1/(2π) and hence η ... Web21 lug 2024 · The review shows how the method for computing gravitational fine-grained entropy, developed over the past 15 years, can be extended to capture the entropy of Hawking radiation. This technique reveals large corrections needed for the entropy to be consistent with unitary black hole evaporation. 16 More Received 5 December 2024
