论文摘要
插入物质可能会破坏黑洞并揭露裸露的奇异性。因此，彭罗斯（Penrose）提出了弱宇宙审查制度的猜想，以避免这种可能性。另一方面，如果从黑洞热力学的第二定律中，黑洞没有被插入物质破坏，则黑洞熵应增加，这是由于插入物质所携带的信息而增加。在这项工作中，我们通过在较高衍生性重力理论中扰动近超级黑洞的例子来证明，第二定律暗示着脆弱的宇宙审查制度。我们还根据黑洞热力学的第一定律将我们的提议与Sorce和Wald制定的提案进行比较，并表明在这种情况下，后者未能产生弱宇宙审查。最后，我们证明了我们对通用重力理论的提议。
Infalling matter may destroy a black hole and expose the naked singularity. Thus, Penrose proposed the weak cosmic censorship conjecture to avoid such a possibility. On the other hand, if the black hole is not destroyed by infalling matter, from the second law of black hole thermodynamics, the black hole entropy should increase due to the information carried by the infalling matter. In this work, we demonstrate by examples of perturbative near-extremal black holes in higher derivative gravity theories that the second law implies weak cosmic censorship. We also compare our proposal to the one developed by Sorce and Wald based on the first law of black hole thermodynamics and show that the latter fails to yield weak cosmic censorship in such cases. Finally, we give proof of our proposal for generic gravity theories.
