  The asymptotic safety program strives for a consistent description of gravity
as a non-perturbatively renormalizable quantum field theory. In this framework
the gravitational interactions are encoded in a renormalization group flow
connecting the quantum gravity regime at trans-Planckian scales to observable
low-energy physics. Our proceedings reviews the key elements underlying the
predictive power of the construction and summarizes the state-of-the-art in
determining its free parameters. The explicit construction of a realistic
renormalization group trajectory describing our world shows that the flow
dynamically generates two scales: the Planck scale where Newton's coupling
becomes constant and a terrestrial scale where the cosmological constant
freezes out. We also review the perspectives of determining the free parameters
of the theory through cosmological observations.
