Cosmic Censorship and Self Force Effects Around the Black Holes

Abstract

Gravitational singularities exists when the gravitational forces becomes very strong in some region, leading to the break down of laws of physics. Penrose formulated a conjecture which relates the information between inside and outside the black hole and named it cosmic censorship conjecture. This conjecture has mainly two parts, weak and strong cosmic censorship conjecture. According to the weak cos mic censorship there won’t be naked singularities while the future evolution of system corresponds to the strong cosmic censorship conjecture. There are sev eral studies to these conjectures but still it is mystery that exactly under which physical process we can find the validity/violation of these conjectures. We give a comprehensive review and study the weak cosmic censorship by overcharging the Reissner Nordstorm black hole with global monopole charge. We also study the overcharging of the charged BTZ black hole. We have find the conditions on particle energy required to overcharge the black hole. We study the overspinning of Kerr Newman Kasuya black hole and find the conditions on particle angular momentum required to overspin the black hole. Also we study the self-force effects of a particle moving around a charged BTZ black hole.
