摘要：

Hawking's black hole area theorem can be tested by monitoring the evolution of a single black hole over time. Using current imaging observations of two supermassive black holes M87* and Sgr A* from the Event Horizon Telescope (EHT), we find their horizon area variation fractions are consistent with the prediction of the black hole area law at the 1 sigma confidence level. We point out that whether the black hole area law is valid or not could be determined by future high-precision EHT observations of Sgr A*. Copyright (c) 2023 EPLA
