[Interview] A Clever Hack to Solve The Hubble Tension Aug 26, 2023

Show notes

There is a disagreement in measurements of the Hubble constant often referred to as The Crisis in Cosmology. One way to solve it is to observe redshift drift. However, it requires lengthy observations. But my guest, Dr Geraint Lewis, has a hack up his sleeve — gravitational lensing.
