Query: Asymptotically safe gravity   This is an introduction to asymptotically safe quantum gravity, explaining
the main idea of asymptotic safety and how it could solve the problem of
predictivity in quantum gravity. In the first part, the concept of an
asymptotically safe fixed point is discussed within the functional
Renormalization Group framework for gravity, which is also briefly reviewed. A
concise overview of key results on asymptotically safe gravity is followed by a
short discussion of important open questions. The second part highlights how
the interplay with matter provides observational consistency tests for all
quantum-gravity models, followed by an overview of the state of results on
asymptotic safety and its implications in gravity-matter models. Finally,
effective asymptotic safety is briefly discussed as a scenario in which
asymptotically safe gravity could be connected to other approaches to quantum
gravity.
