# CDT and Cosmology

## TL;DR

This paper explores how Causal Dynamical Triangulations (CDT) can model quantum gravity and its potential to naturally produce a de Sitter universe, linking quantum gravity approaches with cosmological observations.

## Contribution

It analyzes the cosmological implications of CDT, especially its ability to generate a de Sitter universe, highlighting its relevance for quantum gravity and cosmology.

## Key findings

- CDT can produce a de Sitter universe in its scaling limit.
- The approach emphasizes the importance of causal structure in quantum gravity.
- Potential connections between CDT and observable cosmological phenomena.

## Abstract

In the approach of Causal Dynamical Triangulations (CDT), quantum gravity is obtained as a scaling limit of a non-perturbative path integral over space-times whose causal structure plays a crucial role in the construction. After some general considerations about the relation between quantum gravity and cosmology, we examine which aspects of CDT are potentially interesting from a cosmological point of view, focussing on the emergence of a de Sitter universe in CDT quantum gravity.
