The Dimension of Decompactified Spacetime from String Theory

TL;DR

This paper explores how string theory can explain the emergence of a four-dimensional spacetime through a computer model simulating early universe expansion influenced by string winding modes, highlighting the role of initial conditions.

Contribution

It introduces a computer simulation model that links string winding modes to spacetime decompactification, providing a new perspective on the dimensionality of the universe.

Findings

Decompactified four-dimensional spacetime can result from specific initial conditions.

String winding modes influence inflationary dynamics in the early universe.

The model supports string theory's explanation for the observed spacetime dimensions.

Abstract

The implications of string theory for understanding the dimension of decompactified spacetime are discussed. Results from a computer model designed to simulate expansion of the early universe during the string dominated phase are presented. This model focuses on the effects of string winding modes on inflation and is based on the theory of random walks. We demonstrate that our decompactified four-dimensional spacetime can be explained by the proper choice of initial conditions.
