Hawking equation
WebOct 1, 2024 · With the help of radiation power expression, one can compute total energy emitted as Hawking radiation by multiplying the power with black hole evaporation time scale and this must be equal to the total mass of the black hole by virtue of energy conservation. This may provide an insight to the process of black hole evaporation. WebMay 2, 2024 · The new Hawking-Hertog assessment indicates that there can only be universes that have the same laws of physics as our own. That conjecture means that our Universe is typical and so observations...

http://scholarpedia.org/article/Bekenstein-Hawking_entropy WebThe black hole information paradox [1] is a puzzle that appears when the predictions of quantum mechanics and general relativity are combined. The theory of general relativity predicts the existence of black holes that are regions of spacetime from which nothing — not even light — can escape. In the 1970s, Stephen Hawking applied the rules ...
