Instabilities of naked singularities and black hole interiors in General Relativity
Gustavo Dotti, Reinaldo J. Gleiser, Jorge Pullin +2
Metrics representing black holes in General Relativity may exhibit naked singularities for certain values of their parameters. This is the case for super-extremal () Ker…
Conditional probabilities with Dirac observables and the problem of time in quantum gravity
Rodolfo Gambini, Rafael Porto, Sebastian Torterolo +1
We combine the "evolving constants" approach to the construction of observables in canonical quantum gravity with the Page--Wootters formulation of quantum mechanics with a relatio…
Diffeomorphism invariance in spherically symmetric loop quantum gravity
Rodolfo Gambini, Jorge Pullin
We study the issue of the recovery of diffeomorphism invariance in the recently introduced loop quantum gravity treatment of the exterior Schwarzschild space-time. Although the loo…
Emergent diffeomorphism invariance in a discrete loop quantum gravity model
Rodolfo Gambini, Jorge Pullin
Several approaches to the dynamics of loop quantum gravity involve discretizing the equations of motion. The resulting discrete theories are known to be problematic since the first…
Black holes in loop quantum gravity: the complete space-time
Rodolfo Gambini, Jorge Pullin
We consider the quantization of the complete extension of the Schwarzschild space-time using spherically symmetric loop quantum gravity. We find an exact solution corresponding to…
Modern space-time and undecidability
Rodolfo Gambini, Jorge Pullin
The picture of space-time that Minkowski created in 1907 has been followed by two important developments in physics not contained in the original picture: general relativity and qu…
