如果一个黑洞可以吸积一个其自旋或电荷会使黑洞参数超过极值极限的物体,那么一个裸奇点可能会形成,这违反了宇宙审查猜想。我们回顾了以前的一些结果测试宇宙审查以这种方式使用测试体近似,主要集中在中性黑洞的情况下。在某些条件下,黑洞确实可以在这种近似下过度旋转或过度充电,因此必须考虑辐射和自作用力效应以进一步测试宇宙审查。
If a black hole can accrete a body whose spin or charge would send the black hole parameters over the extremal limit, then a naked singularity would presumably form, in violation of the cosmic censorship conjecture. We review some previous results on testing cosmic censorship in this way using the test body approximation, focusing mostly on the case of neutral black holes. Under certain conditions a black hole can indeed be over-spun or over-charged in this approximation, hence radiative and self-force effects must be taken into account to further test cosmic censorship.
