Explore key cosmological tensions and their implications in this physics seminar from Boston University's Martin Schmaltz at the Institute for Advanced Study. Delve into recent developments surrounding the Hubble tension, growth of structure tension (including S8, growth rate, and Lyman Alpha), and Big Bang Nucleosynthesis challenges related to Lithium and Deuterium. Examine compelling evidence suggesting dark matter may exist within a broader dark sector, potentially interacting with dark radiation, offering new perspectives on these cosmological anomalies.
