Quantum Gravity, Cosmology, (Liouville) Strings and Lorentz Invariance

TL;DR

This paper reviews non-critical string theory's potential to unify quantum gravity and cosmology, emphasizing Lorentz invariance violation and the role of Liouville strings in this context.

Contribution

It introduces non-critical string frameworks as a unified approach to quantum gravity and cosmology, highlighting their capacity to incorporate Lorentz invariance violation.

Findings

Non-critical strings may serve as a unifying framework for quantum gravity and cosmology.

Liouville strings provide a mechanism for Lorentz invariance violation.

The approach offers new insights into the interplay between string theory and cosmological phenomena.

Abstract

I review some aspects of non-critical strings in connection with Lorentz-Invariance violating approaches to quantum gravity. I also argue how non-critical strings may provide a unifying framework where string Cosmology and quantum gravity may be tackled together.
