Cosmic strings reborn?

TL;DR

This paper reviews the renewed interest in cosmic strings driven by string theory models and tentative observational evidence, discussing their current scientific status.

Contribution

It provides a comprehensive overview of the latest developments and potential implications of cosmic strings in light of recent theoretical and observational findings.

Findings

String theory models suggest the possible existence of cosmic strings.

Tentative observational evidence hints at their effects.

Current status of cosmic strings is actively being reassessed.

Abstract

There are two main reasons for the recent renewal of interest in cosmic strings: Fundamental string-theory models suggest their existence; and there are at least two tentative observations of their possible effects. In this talk, I review their current status in the light of these two factors.
