152 - Geraint F. Lewis: Is The Universe Fine-Tuned For Life?

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?
