 :

Modern cosmology rests upon the Cosmological Principle or FLRW paradigm, namely the assumption that the Universe is isotropic and homogeneous at large scales. Working within these assumptions, we are witnessing a potential 5 sigma discrepancy in the Hubble constant H0 between early and late Universe determinations. I will explain how this discrepancy may be an artifact of a breakdown of FLRW at large scales. If true, we're looking at paradigm shift in cosmology.

    Abstract: Quantum field theories and string theories often lead to perturbative series which encode geometric information. In this lecture I will argue that, in the case of complex Chern-Simons theory, perturbative series secretly encode integer invariants, related in some cases to BPS counting. The framework which makes this relation possible is the theory of resurgence, where perturbative ser...
