Spacetime is Doomed - and Quantum Mechanics too

Recently I again beat my head on the brick wall of my incomprehension of physics in a comment to @por500bolos, who has some competence in the field. Rather than pointing out how dumb I am, he kindly refrained, yet I was bitten once again by the frustration of my failure to resolve relativity and quantum mechanics. I guess I'm not alone. No one I am aware of claims to have resolved them credibly. Hunting for more information, I was alerted to the title of a talk by Nima Arkani-Hamed at PSW Science, 'The Doom of Spacetime'.

I am deeply gratified now to be even more out of my depth, as his attempt at resolution seems beyond my ken, and I can make little of the geometric structures he claims underlie both spacetime and quantum mechanics, that emerge from the relationships of the faces, spaces, and vertices of his diagrams.

Just so I won't be the only one on Hive completely baffled, I have endeavored to share the talk here, on Hive. It's a couple hours, complete with the Q&A afterwards, which I quite enjoy and am glad was left in. I hope folks with a passing interest in physics that grasp the problem with resolving classical and quantum physics enjoy the reduction of both to an emergence from Nima's novel geometry.

If you are fascinated by bright, shiny objects like I am, PSW provides an application for membership and a very strong program of talks that range across the sciences. I'm like an addict that has been trapped in a crack house time loop on their site. You just might enjoy it too.
