论文摘要
最近，Li和Bambi提出了一个假设，即常规黑洞的事件范围可能会被破坏，因为这些物体没有引力奇异性，因此不受弱宇宙审查猜想（WCCC）的保护。在本文中，为了检验他们的假设，我们执行了Sorce和Wald提出的Gedanken实验的新版本，以使近乎极端的静态静态静电电气定期黑洞过度充电。在引入时空的稳定性条件和物质场的无效条件之后，我们基于Iyer-Wald形式主义得出了扰动物质领域的一阶和二阶扰动不等式。结果，我们发现这些常规的黑洞在这两个扰动不等式之后，即使不受WCCC的保护，这些常规黑洞也不能在二阶近似情况下破坏。我们的结果表明，可能有更深层次的机制来保护黑洞的事件范围。
Recently, Li and Bambi proposed a hypothesis that the event horizon of a regular black hole can be destroyed because these objects have no gravitational singularity and therefore they are not protected by the weak cosmic censorship conjecture (WCCC). In this paper, to test their hypothesis, we perform the new version of the gedanken experiments proposed by Sorce and Wald to overcharge a near extremal static electrically regular black hole. After introducing the stability condition of the spacetime and the null energy condition of matter fields, we derive the first-order and second-order perturbation inequalities of the perturbation matter fields based on the Iyer-Wald formalism. As a result, we find that these regular black holes cannot be destroyed under the second-order approximation after these two perturbation inequalities are taken into account, even though they are not protected by the WCCC. Our results indicate that there might be some deeper mechanisms to protect the event horizon of the black holes.
