The thermodynamic theory of black holes
WebSep 5, 2024 · Craig Callender, a philosopher of science at the University of California, San Diego, argues that the connection between black holes and thermodynamics is less ironclad than assumed. Peggy Peattie for Quanta Magazine. In the early 1970s, people studying general relativity, our modern theory of gravity, noticed rough similarities between the ... WebUnderstanding the ‘Area Law,’ in regards to the black hole entropy, based on an underlying fundamental theory has been one of the goals pursued by all models of quantum gravity. In black hole thermodynamics, black hole entropy is a measure of uncertainty or lack of information about the actual internal configuration of the system.
