Sabine Hossenfelder on Physics Funding in Academia

See Loop Quantum Gravity which sounds to me a bit like Twistor Theory but trying to make the Twistors the actual fabric of the Universe, rather than a way of describing what we observe when we make experiments. Sabine and I are caught up in something horribly big:
Even Roger Penrose is up against it, and he got to lecture at Cambridge, once back in 1999 and last week, but he said he got a very cool reception. See Curt Jaimungal Talking With Roger Penrose.
34:37 Cool to see a diagram of first cohomology.
1:05:22 About not thinking that Twistor Theory had anything to do with General Relativity, because it was based on conformally flat space-time. See Sabine Hossenfelder and Steve Mould on Gravitation, in particular to the paper Lasenby, Doran & Gull (1998[2004]) Gravity, Gauge Theories and Geometric Algebra:
A new gauge theory of gravity is presented. The theory is constructed in a flat background spacetime and employs gauge fields to ensure that all relations between physical quantities are independent of the positions and orientations of the matter fields. In this manner all properties of the background spacetime are removed from physics, and what remains are a set of `intrinsic' relations between physical fields.

Here's his talk at IAI after he got the Nobel Prize:
There are Googly problems everywhere! Neil Turok solved one with a see-saw mechanism. It's childs-play, what's the problem here? See Neil Turok on Lambda CDM and Peter Voit and Edward Frenkel on Unification in Physics and Mathematics.

Long dark night, ... actually it's 1:40 AM and I'm going to bed. Goodnight.
