Seminarium Teorii Względności i Grawitacji

I will discuss the impact of quantum gravity effects for cosmology, considering the emergent spacetime scenario based on the group field theory framework. Considering some simple models, I will show that there are significant departures from the standard picture for the history of our Universe, both at early and late times. In particular, I will show how it is possible to achieve a bounce and an early epoch of accelerated expansion in this approach. (based on Phys.Lett. B764 (2017) 49-53 and Phys.Rev. D94 (2016) no.6, 064051).
