Dr. Adam Riess, Physics Nobel Prize laureate, discusses the Hubble Tension and the discrepancies in measuring the expansion of the Universe. They explore the significance of Cepheid variables, advancements in instruments like the James Webb Space Telescope, and the impact of dark energy. They also delve into measuring the cosmological constant and the challenges of finding supernovae. The concept of time dilation and the use of quasars as distance measuring tools are highlighted.
