Seeking String Theory in the Cosmos

TL;DR

This paper reviews the theoretical basis, formation, observational detection methods, and current constraints of cosmic strings within string theory, highlighting their significance in understanding the universe.

Contribution

It provides a comprehensive overview of cosmic strings in string theory, including formation mechanisms, observational techniques, and current observational constraints.

Findings

Cosmic strings are theoretically predicted in string theory.

Current observations place significant constraints on cosmic string models.

Multiple observational techniques are actively used to detect cosmic strings.

Abstract

We review the existence, formation and properties of cosmic strings in string theory, the wide variety of observational techniques that are being employed to detect them, and the constraints that current observations impose on string theory models.
