Geraint F. Lewis is Professor of Astrophysics at the Sydney
Institute for Astronomy in the University of Sydney’s School of
Physics. While the focus of his research is on dark matter and
energy, Geraint has written about and worked on many topics in
cosmology and astrophysics more generally. In this episode,
Robinson and Geraint discuss the question of fine-tuning: Our
universe seems extremely well-suited for life, and with just the
slightest variations in physics life as we know it would not
exist. In what ways does the universe appear finely tuned, and
how should we account for this?
