Description

Asymptotic Safety provides a possible mechanism for a consistent and
predictive high-energy completion of gravity and gravity-matter theories.
The key ingredient in the construction is an interacting renormalization
group fixed point which controls physics at trans-Planckian scales.
Relevant couplings have the task of identifying a given asymptotically
safe theory within the unstable manifold of this fixed point. In this talk
I will summarize the basic ideas underlying the construction and discuss
the cosmological constant problem and hierarchy problem based on this
fundamental perspective.
