论文摘要
我们考虑了Minkowski，de Sitter或Anti-De保姆背景中最大扩展的Reissner-Nordström解决方案的稳定性。在广泛的情况下，先前的工作表明，无质量标量场的球形对称扰动会导致RN黑洞的内部地平线变得奇异而崩溃。即使是这种情况，观察者仍然有可能在完全崩溃之前穿过内部地平线，从而违反了强大的宇宙审查制度。在这项工作中，我们表明内部地平线的崩溃和沿着内部地平线的奇异性的发生足以防止观察者进入白洞区域和最大扩展RN时空的平行宇宙区域。因此，如果观察者穿过内在的地平线，他们将不可避免地击中中心奇异性。在本文中，我们使用c = g =4πε_0= 1的天然单元。
We consider the stability of the maximally-extended Reissner-Nordström solution in a Minkowski, de Sitter, or anti-de Sitter background. In a broad class of situations, prior work has shown that spherically symmetric perturbations from a massless scalar field cause the inner horizon of an RN black hole to become singular and collapse. Even if this is the case, it may still be possible for an observer to travel through the inner horizon before it fully collapses, thus violating strong cosmic censorship. In this work, we show that the collapse of the inner horizon and the occurrence of a singularity along the inner horizon are sufficient to prevent an observer from accessing the white hole regions and the parallel universe regions of the maximally extended RN space-time. Thus, if an observer passes through the inner horizon, they will inevitably hit the central singularity. Throughout this article, we use natural units where c = G = 4 π ε_0 = 1.
