We reunite in person after nearly 2 years. Chetan begins this episode with a discussion about Witten's recent work on the deep connection between gauge-gravity amplitudes and geometry in twistor space, and how this suggests a more fundamental language underlying gauge theories and gravity; with many sacred principles of QFTs coming out as emergent. Amartya then elaborates upon signatures of violations of these sacred principles, the IR-UV correspondences used to constrain physics beyond the standard model, extra dimensions, swampland conjectures and the S-matrix bootstrap. Santhosh then rambles about an array of related topics in condensed matter, from density functional theory, percolation theory, equilibrium, thermalization and Anderson Localization, to stochastic thermodynamics and non-hermitian hamiltonians. We discuss how Supersymmetry seems to be the common conceptual bridge between these topics. We close with an array of questions to be discussed subsequently and ramble about how nice it is to be back.
