Wald测试粒子近似方法在弱的宇宙监督假设中的应用

Application of Wald Test Particle Approximation Method in the Weak Cosmic Censorship Conjecture

裸时空奇异点会使所有物理定律在该点失效,彭罗斯提出了宇宙监督假设猜想来避免宇宙中出现裸露的奇点。Wald于1974年提出一个思想实验来考察宇宙监督假设在特定背景下是否成立。本文回顾了Wald当年提出的思想实验,并介绍了一些近些年来基于该思想实验来证明/证伪该猜想的研究成果。

The naked singularities will break down all the laws of physics. Roger Penrose conceived the Cosmic Censorship Conjecture (CCC) to avoid the naked singularities. A gedanken experiment was given by Wald in 1974 to investigate the CCC. We reviewed the Wald’s gedanken experiment and introduced the research progress in recent years.
