Quantum Gravity in Practice
Abstract: I present a recent concrete calculation in Spinfoam Cosmology -the application of the covariant LQG techniques to the cosmos- as an example to discuss a number of conceptual issues that are at the core of quantum gravity and cosmology. These include: What are the observables when localization does not rely on background space and time? What are the degrees of freedom? What is the role of quantum fluctuations of spacetime? What’s the interplay between the Planck scale and the cosmological scale? How should we think about time in this picture?
Part of our ongoing Cosmology Beyond Spacetime online seminar series. See the full list of talks here.
Talks in this series will be held in Zoom webinar format and pre-registration is required.
