Wormhole cosmic strings.
We construct regular multi-wormhole solutions to a gravitating σ model in three space-time dimensions, and extend these solutions to cylindrical traversable wormholes in four and five dimensions. We then discuss the possibility of identifying wormhole mouths in pairs to give rise to Wheeler wormholes. Such an identification is consistent with the original field equations only in the absence of ...
متن کاملCosmic censorship and the dilaton.
We investigate extremal electrically charged black holes in Einstein-Maxwell-dilaton theory with a cosmological constant inspired by string theory. These solutions are not static, and a timelike singularity eventually appears which is not surrounded by an event horizon. This suggests that cosmic censorship may be violated in this theory.
متن کاملGravitational Collapse and Cosmic Censorship
This article gives an elementary overview of the end-state of gravitational collapse according to classical general relativity. The focus of discussion is the formation of black holes and naked singularities in various physically reasonable models of gravitational collapse. Possible implications for the cosmic censorship hypothesis are outlined. based on a talk given at the XVIIIth meeting of t...
متن کاملGravitational Collapse and Cosmic Censorship
We review the status of the weak cosmic censorship conjecture, which asserts, in essence, that all singularities of gravitational collapse are hidden within black holes. Although little progress has been made toward a general proof (or disproof) of this conjecture, there has been some notable recent progress in the study of some examples and special cases related to the conjecture. These result...
متن کاملCosmic 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...
