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.

Classical space telescopes have their limit. You can't simply build bigger mirrors all the time. Instead, you can build more mirrors and combine them into a telescope array. That's the concept behind the Nautilus Array which we discuss with Prof. Daniel Apai from The University of Arizona.
