Numerical Approaches to Spacetime Singularities [PDF]

open access: yesLiving Reviews in Relativity, 1998
This review updates a previous review article. Numerical explorationof the properties of singularities could, in principle, yield detailed understanding of their nature in physically realistic cases.

Numerical Approaches to Spacetime Singularities [PDF]

open access: yesLiving Reviews in Relativity, 2002
This Living Review updates a previous version which is itself an update of a review article. Numerical exploration of the properties of singularities could, in principle, yield detailed understanding of their nature in physically realistic cases ...

Quantum Probes of Spacetime Singularities [PDF]

open access: yesPhysical Review D, 1995
It is shown that there are static spacetimes with timelike curvature singularities which appear completely nonsingular when probed with quantum test particles. Examples include extreme dilatonic black holes and the fundamental string solution.

Resolving Spacetime Singularities within Asymptotic Safety [PDF]

open access: yesPhysical Review Letters, 2019
A key incentive of quantum gravity is the removal of spacetime singularities plaguing the classical theory. We compute the non-perturbative momentum-dependence of a specific structure function within the gravitational asymptotic safety program which ...

Spacetime singularities and invariance [PDF]

open access: yesBelgrade Philosophical Annual, 2016
This paper explains why spacetime singularities do not constitute a breakdown of physical laws, and points out that the difference between the metrics at singularities and those outside of singularities is factual, rather than nomological.

Spacetime Singularities [PDF]

open access: yes, 2013
We present here an overview of our basic understanding and recent developments on spacetime singularities in the Einstein theory of gravity. Several issues related to physical significance and implications of singularities are discussed.

A $$1+5$$ 1 + 5 -dimensional gravitational-wave solution: curvature singularity and spacetime singularity

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
We solve a $$1+5$$ 1 + 5 -dimensional cylindrical gravitational-wave solution of the Einstein equation, in which there are two curvature singularities. Then we show that one of the curvature singularities can be removed by an extension of the spacetime ...

The nature of spacetime singularities [PDF]

open access: yes, 2005
Present knowledge about the nature of spacetime singularities in the context of classical general relativity is surveyed. The status of the BKL picture of cosmological singularities and its relevance to the cosmic censorship hypothesis are discussed.

Trans-Planckian Censorship and Spacetime Singularities

open access: yesMathematics, 2023
We study the effects of trans-Planckian censorship conjecture (TCC) bounds on geodesic completeness of spacetime and the associated existence for an infinite proper time.

Dynamics of critical collapse

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
Critical collapse of a massless scalar field in spherical symmetry is systematically studied. We combine numerical simulations and asymptotic analysis, and synthesize critical collapse, spacetime singularities, and complex science.
