PIRSA:20040088  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Covariant Loop Quantum Gravity, the State of the Art
Speaker(s): Carlo Rovelli
Abstract: The covariant (spinfoam) formulation of loop gravity is a tentative physical quantum theory of gravity with well defined transition amplitudes.  I give my current understanding of the state of the art in this research direction, the issues that are open and need to be explored, and the curr... read more

PIRSA:16070003  ( MP4 Medium Res , MP3 , PDF ) Which Format?
A possible quantum gravity observation. Cosmic rays from Planck stars: black holes decay via tunneling.
Speaker(s): Carlo Rovelli
Abstract: The possibility of observing quantum gravitational phenomena, viewed as remote until not long ago, is increasingly considered to be plausible.  A potentially observable phenomenon is the decay of black holes via a quantum gravitational tunneling akin to standard nuclear decay.  Loo... read more

PIRSA:15060006  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Black hole decay and Fast Radio Bursts
Speaker(s): Carlo Rovelli
Abstract: Quantum effects render black holes unstable.  Besides Hawking radiation there is another, genuinely quantum gravitational, source of instability: the Hajicek-Kiefer explosion via tunnelling to a white hole.  A recent result in classical general relativity makes this decay channel p... read more

Promising Paths: What Have We Learned So Far About Quantum Gravity?
Abstract: In LQG we work in the spirit of Antonio Machado: "Traveler, there is no path; Paths are made by walking." I will present a bird's eye view of some of the paths that have emerged since Loops 11 and offer a few suggestions.I try to make the point about what we know and what we do not yet know about th... read more

Transition Amplitudes in Quantum Gravity
Speaker(s): Carlo Rovelli
Abstract: The covariant formulation of loop quantum gravity has developed strongly during the last few years.  I summarize the current definition of the theory and the results that have been proven. I discuss what is missing towards of the goal of defining a consistent quantum theory whose classical ... read more
