Quantum gravity seeks to reconcile general relativity with quantum field theory, providing a consistent description of spacetime at all energy scales. This workshop aims to explore the interplay between different approaches of quantum gravity at the Planck scale, such as for instance canonical and covariant loop quantum gravity, group field theory and asymptotically safe gravity, and their corresponding low-energy effective descriptions. We aim to discuss how characteristic properties at the Planck scale might leave an imprint in the effective description of gravitational phenomena at macroscopic scales. Main topics include the application in cosmology and the gravitational collapse, modified gravity and the role of physical (quantum) reference frames in the effective description. By bringing together experts from different areas of quantum gravity, one of the main focuses of the workshop is on comparing different methods for accessing the low-energy sector and analysing possible physical implications of quantum gravity across different scales.
