Study of Early Universe in an M Theoretic Model

TL;DR

This paper explores the early universe within M theory, focusing on intersecting branes and their role in the anisotropic expansion and stabilization of spatial dimensions.

Contribution

It introduces a model of the early universe based on BPS intersecting branes in M theory, explaining the stabilization of extra dimensions.

Findings

Three spatial directions expand indefinitely.

Remaining directions stabilize at finite values.

Provides a physical mechanism for stabilization.

Abstract

In this thesis we study early universe in the frame work of M theory. In particular We assume that the early universe is homogeneous, anisotropic, and is dominated by the mutually BPS 22'55' intersecting branes of M theory. We find that, asymptotically, three spatial directions expand to infinity and the remaining spatial directions reach stabilised values. We give a physical description of the stabilisation mechanism.
