There's a crisis in cosmology when it comes to understanding a little thing like the acceleration of our universe, aka The Hubble Tension. And in this episode, Izzie Clarke and Dr Becky Smethurst are digging into what this is and (trying to) explain the science behind it.

A huge thank you to our guests, (Nobel Prize winning-) Professor Adam Riess from John Hopkins University and Professor Silvia Galli from Institut d'Astrophysique de Paris.
