Populating the landscape in an inhomogeneous universe

چکیده
The primordial Universe might be highly inhomogeneous. We perform the 3+1D Numerical Relativity simulation for evolution of scalar field in an initial inhomogeneous expanding Universe, and investigate how it populates landscape with both de Sitter (dS) AdS vacua. results show that eventually either different region separates into vacua, so dS or bubbles (the bubble wall is but spacetime inside contracting) come being clear bounderies, overall a few smaller (which collapsed black holes) inhomogeneously collapsing.

Populating the whole landscape.
Every de Sitter vacuum can transition to every other de Sitter vacuum despite any obstacle, despite intervening anti-de Sitter sinks, despite not being connected by an instanton. Eternal inflation populates the whole landscape.
متن کاملObstacle to populating the string theory landscape
We construct domain walls and instantons in a class of models with coupled scalar fields, determining, in agreement with previous studies, that many such solutions contain naked timelike singularities. Vacuum bubble solutions of this type do not contain a region of true vacuum, obstructing the ability of eternal inflation to populate other vacua. We determine a criterion that potentials must sa...
متن کاملPopulating the Landscape: A Top Down Approach
We put forward a framework for cosmology that combines the string landscape with no boundary initial conditions. In this framework, amplitudes for alternative histories for the universe are calculated with final boundary conditions only. This leads to a top down approach to cosmology, in which the histories of the universe depend on the precise question asked. We study the observational consequ...
متن کاملQuantum creation of an Inhomogeneous universe
In this paper we study a class of inhomogeneous cosmological models which is a modified version of what is usually called the Lemâitre-Tolman model. We assume that we have a space with 2-dimensional locally homogeneous spacelike surfaces. In addition we assume they are compact. Classically we investigate both homogeneous and inhomogeneous spacetimes which this model describe. For instance one i...
متن کاملCosmological Magnetic Fields Limits in an Inhomogeneous Universe
We study the effect of inhomogeneities in the matter distribution of the universe on the Faraday rotation of light from distant QSOs and derive new limits on the cosmological magnetic field. The matter distribution in the Universe is far from being homogeneous and, for the redshifts of interest to rotation measures (RM), it is well described by the observed Ly-α forest. We use a log-normal dist...
