Renate Loll (Radbound University, Nijmegen): 'Questions on Quantum Gravity'
My talk will give a broad-brush account of the field of quantum gravity, with an emphasis on structural issues. I will sketch motivations, ambitions and challenges of quantum gravity, how we got to where we are, and discuss promising current and future directions, focusing on nonperturbative quantum field-theoretic approaches. I will describe available tools, why it has taken a long time to put gravity on the lattice correctly (`a la CDT), and highlight two prominent nonperturbative results, dimensional reduction at the Planck scale and spacetime emergence. My presentation will be based loosely on "Quantum Gravity in 30 Questions”, arXiv:2206.06762.
With speaker’s consent, talks will be recorded and published on YouTube. Our channel is:
