Peter Woit ("Not Even Wrong" blog) reported today on two recent talks by Edward Witten which are available video online.

Here is the link to Woit's blog, which gives an brief overview of what the talks are about.

Thread 'LQG Legend Writes Paper Claiming GR Explains Dark Matter Phenomena'

A new group of investigators are attempting something similar to Deur's work, which seeks to explain dark matter phenomena with general relativity corrections to Newtonian gravity is systems like galaxies. Deur's most similar publication to this one along these lines was: One thing that makes this new paper notable is that the corresponding author is Giorgio Immirzi, the person after whom the somewhat mysterious Immirzi parameter of Loop Quantum Gravity is named. I will be reviewing the...

Thread 'Detecting Gravitons?'

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...
