I only skimmed the transcript but I will say, Andrew Strominger is behind some very interesting theoretical work on quantum black holes, holographic principle in flat space, and so-called "soft theorems" (symmetries of very low-energy radiation), that altogether look like an important piece of the quantum gravity puzzle. Sabrina Pasterski is another physicist involved in this research, whose name a handful of people might recognize.,(reply>), @Autism-101 Right, celestial holography, that's the "holographic principle in flat space" that I mentioned, and it absolutely looks like a step forward. They've tied it to the hot topic of scattering amplitudes (mapping some of the hidden symmetries of scattering amplitudes into the dual celestial theory), it also connects with the twistor work of Kevin Costello... I believe Hawking's interest was the idea that the quantum information apparently lost in black hole evaporation, is actually contained in the quantum numbers of the soft radiation, an application of the memory effect that Pasterski writes about... There's a lot of connections still to be figured out and assembled into a single big picture.,(reply>), I follow Sabrina and Andrew's work on Celestial Holography. Sabrina worked with Andrew when she was a graduate student at Harvard. They have even written papers together. And Stephen Hawking actually referenced one of Sabrina's solo papers in one of his.,(reply>), ☝️☝️☝️<br>Tell Max i referred you to him for a business investment that will change your financial life.
