Bohmian Mechanics at Space-time Singularities. Ii. Spacelike Singularities
We develop an extension of Bohmian mechanics by defining Bohm-like tra-jectories for quantum particles in a curved background space-time containing a spacelike singularity. As an example of such a metric we use the Schwarzschild metric, which contains two spacelike singularities, one in the past and one in the future. Since the particle world lines are everywhere timelike or lightlike, particle...
متن کاملBohmian Mechanics at Space-time Singularities. I. Timelike Singularities
We develop an extension of Bohmian mechanics by defining Bohm-like tra-jectories for (one or more) quantum particles in a curved background space-time containing a singularity. Part one, the present paper, focuses on timelike singu-larities, part two will be devoted to spacelike singularities. We use the timelike singularity of the (super-critical) Reissner–Nordström geometry as an example. Whi...
متن کاملSpacelike Singularities and String Theory
An interpretation of spacelike singularities in string theory uses target space duality to relate the collapsing Schwarzschild geometry near the singularity to an inflationary cosmology in dual variables. An appealing picture thus results whereby gravitational collapse seeds the formation of a new universe. PACS numbers: 04.70.-s, 11.25.-w String theory is strongly believed to solve the short-d...
متن کاملDimensional Mutation and Spacelike Singularities
I argue that string theory compactified on a Riemann surface crosses over at small volume to a higher dimensional background of supercritical string theory. Several concrete measures of the count of degrees of freedom of the theory yield the consistent result that at finite volume, the effective dimensionality is increased by an amount of order 2h/V for a surface of genus h and volume V in stri...
متن کاملLimits and Spacetime Singularities
We give a covariant characterisation of the Penrose plane wave limit: the plane wave profile matrix A(u) is the restriction of the null geodesic deviation matrix (curvature tensor) of the original spacetime metric to the null geodesic, evaluated in a comoving frame. We also consider the Penrose limits of spacetime singularities and show that for a large class of black hole, cosmological and nul...
