The Hubble Constant: “A Crisis in Cosmology”
Most of us know that since the Big Bang, our universe has been gradually expanding. “The Hubble Constant” is a unit of measurement used to calculate this rate of expansion. Being dubbed a “crisis in cosmology” by astrophysicists, the different techniques for working out The Hubble Constant has resulted in different figures. How do these different figures impact our understanding of the universe? To find out, we were joined by Tamara Davis, a Professor at The University of Queensland, School of Mathematics and Physics.
