## TL;DR

This paper introduces the group field theory condensate approach to quantum cosmology, highlighting its potential to recover continuum spacetime, model accelerated expansion, and control anisotropies and inhomogeneities.

## Contribution

It summarizes the main assumptions of group field theory condensate cosmology and recent advances in modeling cosmological phenomena within this framework.

## Key findings

- Isotropic solutions show accelerated expansion
- Bounce scenarios with controlled anisotropies
- Inhomogeneities exhibit scale-invariant power spectrum

## Abstract

This contribution is an appetizer to the relatively young and fast evolving approach to quantum cosmology based on group field theory condensate states. We summarize the main assumptions and pillars of this approach which has revealed new perspectives on the long-standing question of how to recover the continuum from discrete geometric building blocks. Among others, we give a snapshot of recent work on isotropic cosmological solutions exhibiting an accelerated expansion, a bounce where anisotropies are shown to be under control and inhomogeneities with an approximately scale-invariant power spectrum. Finally, we point to open issues in the condensate cosmology approach.
