Cosmic Censorship in Two - Dimensional Gravity ⋆ Jorge

چکیده
A weak version of the cosmic censorship hypothesis is implemented as a set of boundary conditions on exact semi-classical solutions of two-dimensional dilaton gravity. These boundary conditions reflect low-energy matter from the strong coupling region and they also serve to stabilize the vacuum of the theory against decay into negative energy states. Information about low-energy incoming matter can be recovered in the final state but at high energy black holes are formed and inevitably lead to information loss at the semi-classical level. ⋆ Work supported in part by NSF grants PHY89-17438, PHY 9009850 and R.

Cosmic censorship in 2-dimensional dilaton gravity
Abstract. The global structure of 2-dimensional dilaton gravity is studied, attending in particular to black holes and singularities. A gravitational energy is defined and shown to be positive at spatial singularities and negative at temporal singularities. Trapped points are defined, and it is shown that spatial singularities are trapped and temporal singularities are not. Thus a local form of...
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...
متن کاملCosmic Censorship: The Role of Quantum Gravity
The cosmic censorship hypothesis introduced by Penrose thirty years ago is still one of the most important open questions in classical general relativity. In this essay we put forward the idea that cosmic censorship is intrinsically a quantum gravity phenomena. To that end we construct a gedanken experiment in which cosmic censorship is violated within the purely classical framework of general ...
متن کاملGeneric cosmic-censorship violation in anti-de Sitter space.
We consider (four-dimensional) gravity coupled to a scalar field with potential V(phi). The potential satisfies the positive energy theorem for solutions that asymptotically tend to a negative local minimum. We show that for a large class of such potentials, there is an open set of smooth initial data that evolve to naked singularities. Hence cosmic censorship does not hold for certain reasonab...
متن کاملFinal fate of spherically symmetric gravitational collapse of a dust cloud in Einstein-Gauss-Bonnet gravity
We give a model of the higher-dimensional spherically symmetric gravitational collapse of a dust cloud including the perturbative effects of quantum gravity. The n(≥ 5)-dimensional action with the Gauss-Bonnet term for gravity is considered and a simple formulation of the basic equations is given for the spacetime M ≈ M × K with a perfect fluid and a cosmological constant. This is a generalizat...
