[Interview] A Clever Hack to Solve The Hubble Tension
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.👉 Redshift Drift story on Universe Today:https://www.universetoday.com/162845/a-new-way-to-measure-the-expansion-rate-of-the-universe-redshift-drift/👉 The Redshift Difference in Gravitational Lensed Systems: A Novel Probe of Cosmology:https://arxiv.org/abs/2308.07529👉 Dr Geraint Lewis' website…
