Anisotropy in Born-Infeld brane cosmology

TL;DR

This paper explores a brane-world cosmology model with Born-Infeld matter, demonstrating that the universe evolves from anisotropy to isotropy and transitions into accelerated expansion, aligning with observations.

Contribution

It introduces a novel brane-world model with Born-Infeld matter showing the universe's evolution from anisotropy to isotropy with accelerated expansion.

Findings

Universe evolves from anisotropic to isotropic

Model predicts transition to accelerated expansion

Supports Born-Infeld matter in cosmological evolution

Abstract

The accelerated expansion of the universe together with its present day isotropy has posed an interesting challenge to the numerous model theories presented over the years to describe them. In this paper, we address the above questions in the context of a brane-world model where the universe is filled with a Born-Infeld matter. We show that in such a model, the universe evolves from a highly anisotropic state to its present isotropic form which has entered an accelerated expanding phase.
