As I recall over 90 people are registered as participating. Time has been set aside for informal discussion. All I have listed here are the scheduled talks.

THURSDAY'S TALK "Lionel Mason: Twistors and Feynman amplitudes" puzzled me. I looked at the list of papers of this author, and didn't find anything related to LQG:

I seem to notice a buildup of papers like this: Detecting single gravitons with quantum sensing. (OK, old one.) Toward graviton detection via photon-graviton quantum state conversion Is this akin to “we’re soon gonna put string theory to the test”, or are these legit? Mind, I’m not expecting anyone to read the papers and explain them to me, but if one of you educated people already have an opinion I’d like to hear it. If not please ignore me. EDIT: I strongly suspect it’s bunk but...
