Explore the theoretical framework where asymptotic safety offers a non-perturbative path to quantum gravity, leading to the fundamental emergence of a minimal length scale, often associated with the Planck scale, that limits spacetime resolution.
Explore the profound implications of Planck scale physics within the vast realms of astrophysics and cosmology. This crucial intersection delves into how the most fundamental quantum gravitational phenomena might manifest in observable cosmic events, from the earliest moments of the universe to the extreme environments of black holes. Understand the theoretical frameworks and potential observational signatures shaping our understanding of the cosmos at its most fundamental level.
