How do we know light is constant throughout the universe? What new technology or theory would we need to further develop our understanding of the beginnings of the universe? How do you know that the galaxies are made of certain elements?

This podcast followed his lecture ‘First Light: Revealing the Early Universe’ which was given on 29th May 2024.
