Did JWST Just Solve the Biggest Crisis in Cosmology? Wendy Freedman [Ep. 461]

Discrepancies between different measurements of the Hubble constant have caused a major crisis in cosmology.  Our guest today, the incredible Wendy Freedman, is at the forefront of efforts to resolve this tension. Known for her pioneering work on the Hubble Key Project and her important contributions to the measurement of the Hubble constant, Wendy is now using the James Webb Space Telescope to bring clarity to this debate.  With decades of experience and a deep understanding of the complexity of cosmic measurements, there is no one better to shed light on this issue. So, can the James Webb Space Telescope help solve one of the biggest puzzles in cosmology?
