The Possibility of Cosmic Acceleration via Spatial Averaging in Lemâitre-Tolman-Bondi Models

چکیده
We investigate the possible occurrence of a positive cosmic acceleration in a spatially averaged, expanding, unbound Lemâitre-Tolman-Bondi cosmology. By studying an approximation in which the contribution of three-curvature dominates over the matter density, we construct numerical models which exhibit acceleration.

متن کاملAveraging in spherically symmetric cosmology
The averaging problem in cosmology is of fundamental importance. When applied to study cosmological evolution, the theory of macroscopic gravity (MG) can be regarded as a long-distance modification of general relativity. In the MG approach to the averaging problem in cosmology, the Einstein field equations on cosmological scales are modified by appropriate gravitational correlation terms. We st...
متن کاملInhomogeneity-Induced Cosmic Acceleration in a Dust Universe
Abstract It is the common consensus that the expansion of a universe always slows down if the gravity provided by the energy sources therein is attractive. To examine this point we find counter-examples for a spherically symmetric dust fluid described by the Lemaitre-Tolman-Bondi solution. Thus, the validity of this naive consensus is indeed doubtful and the effects of inhomogeneities should be...
متن کاملThe motion of galaxy clusters in inhomogeneous cosmologies
Lemâıtre-Tolman-Bondi inhomogeneous spacetimes can be used as a cosmological model to account for the type Ia supernova data. However, such models also give rise to large velocities of galaxy clusters with respect to the cosmic microwave background. These velocities can be measured using the kinematic Sunyaev-Zeldovich effect. This paper presents a calculation of galaxy cluster velocities as a ...

Recently, there has been suggestions that the apparent accelerated expansion of the universe is due not to a cosmological constant, but rather to inhomogeneities in the distribution of matter. In this work, we investigate a specific class of inhomogeneous models that can be solved analytically, namely the dust-dominated Lemâitre-Tolman-Bondi universe models. We show that they do not permit acce...
