ALMOST CLASSICAL CREATION OF A UNIVERSE

We study the problem of a 1 + 1 cord with a dynamical massless scalar field living in it, which separates a false vacuum and a conical region in a 2 + 1 space. A stable "particle-like" configuration

Can a man-made Universe be created by quantum tunneling without an initial singularity?

Essentially all modern particle theories suggest the possible existence of a false vacuum state – a metastable state with an energy density that cannot be lowered except by means of a very slow phase

M theory observables for cosmological space-times

We discuss the construction of the analog of an S-matrix for space-times that begin with a Big-Bang and asymptote to an FRW universe with nonnegative cosmological constant. When the cosmological

Vacuum bubble in an inhomogeneous cosmology

We study the propagation of bubbles of new vacuum in a radially inhomogeneous Lemaitre-Tolman-Bondi background that includes a cosmological constant. This exemplifies the classical evolution of a

Consistent Cosmic Bubble Embeddings

The Raychaudhuri equation for null rays is a powerful tool for finding consistent embeddings of cosmological bubbles into a background spacetime in a way that is largely independent of the matter

Is it possible to create a universe out of a monopole in the laboratory

To explore the possibility that an inflationary universe can be created out of a stable particle in the laboratory, we consider the classical and quantum dynamics of a magnetic monopole in the

Observers in an accelerated universe

If the current acceleration of our Universe is due to a cosmological constant, then a Coleman–De Luccia bubble will nucleate in our Universe. In this work, we consider that our observations could be

Evolution of perturbations in an inflationary universe

We analyze the evolution of inhomogeneous density perturbations in a model of the very early universe that is dominated for a time by a constant energy density of a false quantum-mechanical vacuum,

Gravitational collapse and spacetime singularities

accompanied by a violent release of energy, possible in the form of gravitational radiation. The detailed mathematical discussion of such situations is difficult since the full complexity of general

Compactness Criterion for the Formation of Averaged Trapped Surfaces in Gravitational Collapse

S>An average trapped surface is defined as a closed two-surface with the property that the area of the wave fronts forined by light rays emitted in the orthogonal inward and outward directions are

Singular hypersurfaces and thin shells in general relativity

SummaryAn approach to shock waves, boundary surfaces and thin shells in general relativity is developed in which their histories are characterized in a purely geometrical way by the extrinsic
