## Abstract

General relativity taught us that space time is dynamical and quantum theory posits that dynamical objects are quantum. Hence the Newtonian notion of space time as a passive stage where physics takes place needs to be replaced by a notion of quantum space time which is interacting with all other quantum matter fields.

I will present recent developments that aim at constructing quantum space time. In particular I will explain how topological quantum field theories give rise to new quantum geometry realizations and how these serve as starting points for the construction of a dynamics of quantum gravity, which is consistent over all scales. Such a dynamics will then determine the properties of quantum space time.
