Gravitational Singularities

Index Academic
Gravitational singularities in general relativity are spacetime locations where the gravitational field becomes infinite. Scalar invariant curves of spacetime include a measure of matter density. Some physicists and philosophers believe that because the density of matter tends to become infinite in singularity, spacetime laws are no longer valid there.

f Gravity and gravitational singularities

Nature, 1974
TRAUTMAN has postulated1 that the usual space−time singularity occurring in classical cosmological models and in the gravitational collapse of massive objects could be averted if intrinsic spin effects are incorporated into general relativity by adding torsion terms to the usual Einstein field equations, that is through the Einstein−Cartan theory ...

Gravitational lensing by naked singularities

Physical Review D, 2002
We model massive dark objects in galactic nuclei as spherically symmetric static naked singularities in the Einstein massless scalar field theory and study the resulting gravitational lensing in detail. Based on whether or not a naked singularity is covered within a photon sphere we classify naked singularities into two kinds: weakly naked (those ...

The Singularity Problem of Gravitation

Fortschritte der Physik/Progress of Physics, 1988
We review the present status of the singularity problem in gravitation theory. First we repeat the known results for Einstein's theory. After this, different other gravitation theories are considered under the following aspect: Which of the presumptions leading to singularities in Einstein's theory are not fulfilled, and can this prevent the ...

Naked singularities in self-similar gravitational collapse

Physical Review D, 1990
We formulate precise geometric criteria for the development of naked strong-curvature singularities in self-similar spacetimes.

Collision Singularities in Gravitational Problems

1973
The rotating-pulsating coordinate system commonly used in the elliptic restricted problem of three bodies is modified to be useful also in the limit of rectilinear motion of the primaries. In these coordinates the homographic solutions of the problem of n bodies are equilibrium solutions, and so are, in particular, the homothetic solutions leading to a

Gravitational Collapse and Spacetime Singularities

2007
Physical phenomena in astrophysics and cosmology involve gravitational collapse in a fundamental way. The final fate of a massive star when it collapses under its own gravity at the end of its life cycle is one of the most important questions in gravitation theory and relativistic astrophysics, and is the foundation of black hole physics.
