Abstract:
We investigate the laws of thermodynamics and the validity of the cosmic censorship conjecture in the Kerr–Newman–de Sitter black hole under charged particle absorption. Here, the black hole undergoes infinitesimal changes because of the momenta carried by the particle entering it. The cosmic censorship conjecture is tested by whether the black hole can be overcharged beyond the extremal condition under absorption. The changes in the black hole violate the second law of thermodynamics. Furthermore, this is related to the cosmic censorship conjecture. To resolve this violation, we impose a reference energy of the particle at the asymptotic region based on the first law of thermodynamics. Under imposition of the reference energy, the absorption satisfies the laws of thermodynamics, and the extremal black hole cannot be overcharged. Thus, the cosmic censorship conjecture is valid under the absorption.

Abstract:
According to the singularity theorem, a curvature singularity can be formed in a gravitational collapse under the null energy condition. Eventually, the singularity possesses sufficient mass density for the horizon to appear, and the compact object thereby evolves into a black hole. Hence, on the basis of general relativity, the singularity must be located at the center of the black hole. Our curiosity begins here: can we see the singularity? To answer this question, the cosmic censorship conjecture comes into play. That conjecture, which was originally proposed by Penrose, has two versions. The weak version states that a static observer located outside the black hole cannot see the singularity. Furthermore, the strong version states that no observers can see the singularity. Studies regarding the cosmic censorship conjecture are still ongoing, and evidently, its validation requires a deep understanding of the theory of gravity, including general relativity. Herein, we review the progress of studies associated with the weak and the strong cosmic censorship conjectures. Furthermore, we briefly describe the Penrose process for extracting energy from a black hole.

Abstract:
We investigate weak cosmic censorship conjecture in charged torus-like black hole by the complex scalar field scattering. Using the relation between the conserved quantities of a black hole and the scalar field, we can calculate the change of the energy and charge within the infinitesimal time. The change of the enthalpy is connected to the change of energy, then we use those results to test whether the first law, the second law as well as the weak cosmic censorship conjecture are valid. In the normal phase–space, the first law of thermodynamics and the weak cosmic censorship conjecture are valid, and the second law of thermodynamics is not violated. For the specific black hole under scalar field scattering we consider, in the extended phase–space, the first law of thermodynamics and the weak cosmic censorship conjecture are valid. However, the second law of thermodynamics is violated when the black hole’s initial charge reaches a certain value.

Abstract:
In this paper, we investigate the minimal length effects on the thermodynamics and weak cosmic censorship conjecture in a RN-AdS black hole via charged particle absorption. We first use the generalized uncertainty principle (GUP) to investigate the minimal length effect on the Hamilton-Jacobi equation. After the deformed Hamilton-Jacobi equation is derived, we use it to study the variations of the thermodynamic quantities of a RN-Ads black hole via absorbing a charged particle. Furthermore, we check the second law of thermodynamics and the weak cosmic censorship conjecture in two phase spaces. In the normal phase space, the second law of thermodynamics and the weak cosmic censorship conjecture are satisfied in the usual and GUP-deformed cases, and the minimal length effect makes the increase of entropy faster than the usual case. After the charge particle absorption, the extremal RN-AdS black hole becomes nonextremal. In the extended phase space, the black hole entropy can either increase or decrease. When T>2Pr+, the second law is satisfied. When T<2Pr+, the second law of thermodynamics is violated for the extremal or near-extremal black hole. Finally, we find that the weak cosmic censorship conjecture is legal for extremal and near-extremal RN-Ads black holes in the GUP-deformed case.

Abstract:
The weak cosmic censorship conjecture is a central open problem in classical general relativity. Under the assumption of spherical symmetry, Christodoulou has investigated the conjecture for two different matter models; a scalar field and dust. He has shown that the conjecture holds true for a scalar field but that it is violated in the case of dust. The outcome of the conjecture is thus sensitive to which model is chosen to describe matter. Neither a scalar field nor dust are realistic matter models. Collisionless matter, or Vlasov matter, is a simple matter model but can be considered to be realistic in the sense that it is used by astrophysicists. The present status on the weak cosmic censorship conjecture for the Einstein–Vlasov system is reviewed here.

Abstract:
The Penrose strong cosmic censorship conjecture asserts that Cauchy horizons inside dynamically formed black holes are unstable to remnant matter fields that fall into the black holes. The physical importance of this conjecture stems from the fact that it provides a necessary condition for general relativity to be a truly deterministic theory of gravity. Determining the fate of the Penrose conjecture in nonasymptotically flat black hole spacetimes has been the focus of intense research efforts in recent years. In this paper, we provide a remarkably compact proof, which is based on Bekenstein’s generalized second law of thermodynamics, for the validity of the intriguing Penrose conjecture in physically realistic (dynamically formed) curved black hole spacetimes.

Abstract:
End state of gravitational collapse and the related cosmic censorship conjecture continue to be amongst the most important open problems in gravitation physics today. My purpose here is to bring out several aspects related to gravitational collapse and censorship, which may help towards a better understanding of the issues involved. Possible physical constraints on gravitational collapse scenarios are considered. It is concluded that the best hope for censorship lies in analyzing the genericity and stability properties of the currently known classes of collapse models which lead to the formation of naked singularities, rather than black holes, as the final state of collapse and which develop from a regular initial data.

Abstract:
It has been shown previously that an extremal Reissner–Nordström or an extremal Kerr black hole cannot be overcharged or overspun by a test particle, if radiative and self-force effects are neglected. In this paper, we consider extremal charged and rotating black holes with cosmological constants. By studying the motion of test particles, we find the following results: An extremal Reissner–Nordström anti-de Sitter (RN–AdS) black hole can be overcharged by a test particle but an extremal Reissner–Nordström de Sitter (RN–dS) black hole cannot be overcharged. We also show that both extremal Kerr–de Sitter (Kerr–dS) and Kerr–anti-de Sitter (Kerr–AdS) black holes can be overspun by a test particle, implying a possible breakdown of the cosmic censorship conjecture. For the Kerr–AdS case, the overspinning requires that the energy of the particle be negative, a reminiscent of the Penrose process. In contrast to the extremal RN and Kerr black holes, in which cases the cosmic censorship is upheld, our results suggest some subtle relations between the cosmological constants and the cosmic censorship. We also discuss the effect of radiation reaction for the Kerr–dS case and find that the magnitude of energy loss due to gravitational radiation may not be enough to prevent the violation of the cosmic censorship.

Resumo: O objetivo deste trabalho é testar a validade da Conjectura Fraca da Censura Cósmica em espaços-tempo com buracos negros. Essa conjectura foi proposta por Roger Penrose em 1969, e diz que singularidades resultantes de colapso gravitacional de matéria fisicamente razoável estão sempre envolvidas por um horizonte de eventos, ou seja, escondidas de um observador externo. Apesar de muitas evidências a favor dessa conjectura, ela nunca foi provada. Nossa meta é analisar se essa conjectura pode ser violada classicamente sob especificas circunstâncias. Começaremos com uma introdução ao assunto, apresentando os conceitos que nos serão úteis ao longo de nosso trabalho. Depois investigaremos os trabalhos anteriores na área, que visaram destruir o horizonte de eventos de um buraco negro, criando assim uma singularidade nua (visível), e consequentemente violando a conjectura. Por fim, apresentaremos nossos resultados, que podem ser divididos em duas partes: (i) generalização dos casos clássicos obtidos anteriormente, e demonstração, sob dadas condições, da violação da conjectura para um buraco negro de Kerr-Newman e (ii) análise da validade da conjectura para um buraco negro com cinco dimensões em um espaço-tempo assintoticamente AdS, dando assim uma contribuição para a correspondência AdS/CFT
Abstract: The aim of this work is to test the Weak Cosmic Censorship Conjecture in black holes. This conjecture was proposed by Roger Penrose in 1969, and it states that singularities arising from the gravitational collapse of physically reasonable matter are always involved by an event horizon, i.e., they are hidden from an external observer. Despite so much evidence in favor of this conjecture, it has never been proven. Our aim is to analyze if this conjecture can be violated classically under specific circumstances. We will start with an introduction to the subject, presenting the concepts that will be useful throughout the work. After that, we will investigate the previous studies in the field that tried to destroy the event horizon of a black hole, creating a naked (visible) singularity, and hence violating the conjecture. Lastly, we will present our results, which may be divided in two parts: (i) generalization of the classic cases previously obtained, and demonstration, under specific conditions, of the violation of the conjecture in a spacetime with a Kerr-Newman black hole and (ii) study of the validity of this conjecture with a five-dimensional rotating black hole in a asymptotically AdS spacetime, making a contribution to the AdS/CFT correspondence

We explore the cosmic censorship in the Einstein-Maxwell-dilaton theory following Wald’s thought experiment to destroy a black hole by throwing in a test particle. We discover that at probe limit the extremal charged dilaton black hole could be destroyed by a test particle with specific energy. Nevertheless the censorship is well protected if backreaction or self-force is included. At the end, we discuss an interesting connection between Hoop Conjecture and Weak Gravity Conjecture.
