Zusammenfassung:
This is an introduction to the approach to the extraction of cosmological
dynamics from full quantum gravity based on group field theory condensates. We
outline its general perspective, which sees cosmology as the hydrodynamics of
the fundamental quantum gravity degrees of freedom, as well as its concrete
implementation within the group field theory formalism. We summarise recent
work showing the emergence of a bouncing cosmological dynamics from a
fundamental group field theory model, and provide a brief but complete survey
of other results in the literature. Finally, we discuss open issues and
directions for further research.
