Fundamental Strings and Cosmology

TL;DR

This paper demonstrates that the velocity-dependent interactions between parallel fundamental strings can lead to an expanding universe in lower-dimensional spacetime.

Contribution

It introduces a novel connection between string interactions and cosmological expansion in a higher-dimensional framework.

Findings

Velocity-dependent forces induce expansion

Parallel strings influence cosmological dynamics

Higher-dimensional string interactions relate to universe expansion

Abstract

We show that the velocity-dependent forces between parallel fundamental strings moving apart in a D-dimensional spacetime imply an expanding universe in (D-1)-dimensional spacetime.
