Abstract: We show how a cosmological dynamics with a late-time cosmic acceleration and an asymptotic deSitter regime can be obtained from hydrodynamics on minisuperspace, a framework generalising quantum cosmology with non-linear terms. We also show how this hydrodynamics framework can be derived from fundamental quantum gravity models within the tensorial group field theory formalism, an approach closely related to lattice quantum gravity and loop quantum gravity. If time allows, we discuss other results within the same framework, concerning emergent cosmological physics, as well as other research directions leading to it.
