Strong cosmic censorship in light of weak gravity conjecture for charged black holes

نویسندگان

چکیده

In this paper, we investigate the strong cosmic censorship conjecture (SCC) for charged black holes in de Sitter space by considering weak gravity (WGC). Using analytical methods, find that SCC is preserved dS-charged with respect to some restriction $qQ\gg1$ and $r_+\geq Q$ help of WGC condition viz $\frac{q}{m}\geq 1$ scalar fields. Where q, m are charge mass field, $r_+$, Q determine radius outer event horizon hole, respectively. case, when (WGC) valid, will definitely be satisfied holes. On other hand, violated not satisfied. Also, examined RN-dS hole extremality state found can $\Lambda r_+^2=1$.

Charged black holes in Hǒrava gravity

We explore static spherically symmetric black hole solutions allowing a bulk U(1) vector field in the khronometric formulation of Hořava gravity by way of EinsteinÆther. We examine analytic solutions and study numerical results in the limit that the khronon does not backreact on the metric.

End Point of Black Ring Instabilities and the Weak Cosmic Censorship Conjecture.

We produce the first concrete evidence that violation of the weak cosmic censorship conjecture can occur in asymptotically flat spaces of five dimensions by numerically evolving perturbed black rings. For certain thin rings, we identify a new, elastic-type instability dominating the evolution, causing the system to settle to a spherical black hole. However, for sufficiently thin rings the Grego...

Cosmic Censorship in Quantum Gravity

We study cosmic censorship in the Reissner-Nordstrom charged black hole by means of quantum gravity holding near the apparent horizons. We consider a gedanken experiment whether or not a black hole with the electric charge Q less than the mass M (Q < M) could increase its charge to go beyond the extremal limit Q = M by absorbing the external charged matters. If the black hole charge could excee...

Perturbative metric of charged black holes in quadratic gravity.

We consider perturbative solutions to the classical field equations coming from a quadratic gravitational lagrangian in four dimensions. We study the charged, spherically symmetric black hole and explicitly give corrections up to third order (in the coupling constant β multiplying the RμνR μν term) to the Reissner–Nordström hole metric. We consider the thermodynamics of such black holes, in par...

Bulk / Boundary Thermodynamic Equivalence , and the Bekenstein and Cosmic - Censorship Bounds for Rotating Charged AdS Black Holes

We show that one may pass from bulk to boundary thermodynamic quantities for rotating AdS black holes in arbitrary dimensions so that if the bulk quantities satisfy the first law of thermodynamics then so do the boundary CFT quantities. This corrects recent claims that boundary CFT quantities satisfying the first law may only be obtained using bulk quantities measured with respect to a certain ...
