论文摘要
霍金和彭罗斯的奇异定理告诉我们，奇异性在一般相对论中是普遍的位置。奇异性不仅发生在大爆炸的宇宙开头，而且还出现在完全的引力崩溃中，从而导致黑洞的形成。如果奇异性（大爆炸中的一个人）曾经成为“裸体”，即不被黑洞的视野所笼罩，那么预计问题会出现并呈现一般的相对性不确定。因此，彭罗斯（Penrose）提出了宇宙审查制度的猜想，该猜想指出，奇异行为绝不应该是赤裸裸的。此后已经发现了对猜想的各种反例，但仍不清楚在哪种物理过程中，人们可以期望违反猜想的行为。在这篇简短的评论中，我简要介绍了时空奇异性和宇宙审查制度的一些进展。特别是，我将讨论为什么我们仍然应该关心猜想，以及我们是否应该担心一些反例。这并不是一项全面的审查，而是要对该主题进行介绍，而该主题最近看到了兴趣的增加。
The singularity theorems of Hawking and Penrose tell us that singularities are common place in general relativity. Singularities not only occur at the beginning of the Universe at the Big Bang, but also in complete gravitational collapses that result in the formation of black holes. If singularities - except the one at the Big Bang - ever become "naked", i.e., not shrouded by black hole horizons, then it is expected that problems would arise and render general relativity indeterministic. For this reason, Penrose proposed the cosmic censorship conjecture, which states that singularities should never be naked. Various counterexamples to the conjecture have since been discovered, but it is still not clear under which kind of physical processes one can expect violation of the conjecture. In this short review, I briefly examine some progresses in spacetime singularities and cosmic censorship conjecture. In particular, I shall discuss why we should still care about the conjecture, and whether we should be worried about some of the counterexamples. This is not meant to be a comprehensive review, but rather to give an introduction to the subject, which has recently seen an increase of interest.
