Stephen Hawking's black hole laws just got a major upgrade
AI Summary: Researchers at Penn State have developed a new framework for understanding black hole thermodynamics that addresses limitations in Stephen Hawking's original model, which only applies to black holes in equilibrium. The proposed method introduces a new measure of black hole entropy that accounts for dynamic changes, such as formation, merging, and evaporation, by linking it more closely to a black hole's spin and energy. This advancement could enhance the understanding of dynamic astrophysical events involving black holes, as detailed in their publication in *Physical Review Letters*. The study aims to reconcile the behavior of black holes with the laws of thermodynamics in non-static conditions.
