论文摘要
霍金的黑洞区域定理可以通过监测一个黑洞的演变来测试。使用事件范围望远镜（EHT）的两个超质量黑洞M87*和SGR A*的当前成像观测值，我们发现它们的地平线区域变化量与以$ 1 \σ$置信度的预测与黑洞区域定律的预测一致。我们指出，黑洞区域法律是否有效，可以通过SGR A*的未来高精度EHT观察结果来确定。
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 $1\,σ$ 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*.
