论文摘要
在本文中，我们通过吸收颗粒来研究几乎极端Kerr黑洞中弱宇宙审查的猜想。在先前的工作中，他们忽略了黑洞吸收颗粒的过程。他们假设整个粒子可以被吸收，并且发生过度构成。但是，是否可以吸收整个粒子是值得怀疑的。因此，我们将在本文中进行调查。我们考虑具有有限尺寸的粒子的吸收过程。在此吸收过程中，黑洞的参数将会改变。这种变化将阻止粒子的其余部分进入黑洞。我们显示进入黑洞的部分不能超越一个极端的Kerr黑洞。与Sorce和Wald不同，我们解决了Kerr Black Hole的过度问题，而没有辐射效果或自力效应。此外，我们将此过程用于一般的黑洞。在三个假设下，我们表明弱宇宙审查制度是否通过吸收粒子对极端黑洞有效，它对相应的几乎极端黑洞有效。在许多情况下，极端黑洞满足了弱宇宙审查制度的猜想，而相应的几乎极端黑洞不满足。因此，如果这些黑洞满足三个假设，则可以通过吸收过程来解决这些违规。
In this paper, we investigate the Weak Cosmic Censorship Conjecture in nearly extremal Kerr black hole by absorbing particles . In previous work, they ignore the process of black hole absorbing particles. They assume the whole particle can be absorbed and the overspinning occurs. However, it is questionable whether the whole particle can be absorbed. Therefore, we will investigate it in this paper. We consider the absorption process of a particle with finite size. During this absorption process, the black hole's parameters will change. This change will prevent the rest part of particle enter black hole. We show the part entering black hole can not overspin a nearly extremal Kerr black hole. Different from Sorce and Wald, we solve the overspinning problem for Kerr black hole without radiation effect or self-force effect. Further, we use this process to a general black hole. Under three assumptions, we show if Weak Cosmic Censorship Conjecture is valid for an extremal black hole by absorbing a particle, it will be valid for the corresponding nearly extremal black hole. In many situation, the extremal black holes satisfy Weak Cosmic Censorship Conjecture and the corresponding nearly extremal black holes don't satisfy it. Therefore, if those black holes satisfy three assumptions, these violations may be solved by absorption process.
