Instability of Spacelike and Null Orbifold Singularities
arXiv:hep-th/0206228 · doi:10.1103/PhysRevD.66.103512
Abstract
Time dependent orbifolds with spacelike or null singularities have recently been studied as simple models of cosmological singularities. We show that their apparent simplicity is an illusion: the introduction of a single particle causes the spacetime to collapse to a strong curvature singularity (a Big Crunch), even in regions arbitrarily far from the particle.
