The Dimension of Decompactified Spacetime from String Theory

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.
