The search for universality in quantum gravity


The asymptotic safety scenario in quantum gravity hypothesizes that the quantum laws of spacetime geometry approach a scale-invariant regime when examined at smaller and smaller length scales. I will discuss the role of random geometry, critical phenomena and universality in the search for concrete models of scale-invariant quantum geometry that could feature in this scenario. Along the way I will highlight ongoing research in my group related to the theme.
