Episode description
Released: 21 January 2018
Duration: 19 minutes
A hundred years ago cosmologists were struggling to understand the nature and structure of the universe, and at the heart of this struggle was the island universe hypothesis.
Today we find ourselves confronted with a similar question posed at a far greater scale. As we confront these great questions of cosmology, whether a hundred years ago or today, we find ourselves faced with as many philosophical questions as scientific questions when we challenge the boundaries of our understanding. In Part I we focus on the original problems of constructing the cosmological distance ladder.
