引力波观测支持黑洞面积定理

Gravitational wave observations support the black hole area theorem

黑洞面积定理表明黑洞顺时演化面积不会减小,这被证明与热力学第二定律相对应.注意到LIGO近来的4次引力波观测数据均来自双黑洞的融合过程,进而本文利用这些观测数据对面积定理进行验证.结果显示该4次观测结果均支持黑洞面积定理.此外,本文也从理论上给出了N个黑洞融合时面积定理的等价表述.

The black hole area theorem shows that the area of the black hole does not decrease,which corresponds to the second law of thermodynamics. We note that the four gravitational wave observations from LIGO come from the merging process of the double black hole,and thus we use these observed data to validate the area theorem. The four observations all support the black hole area theorem. In addition,we study the merge process of N black hole,and a equivalence representation of the area theorem is obtained in principle.
