Atoms, Aliens and the Meaning of Everything: Paul Ewart vs Simon Walker-Samuel hosted by Sam McKee

Premier Unbelievable guest-hosted by Dr. Sam McKee heads to John Colet School in Wendover, UK for a lively debate on science, religion and reality with Oxford atomic & laser physicist Prof Paul Ewart (Christian; former Faraday Institute director, ex-president of Christians in Science) and UCL biophysics & imaging expert Prof Simon Walker-Samuel (trustee, Humanists UK). Together they explore whether science and faith conflict or complement each other. From fine-tuning and emergence to AI, digital twins in cancer care, consciousness and what it means to be human, our guests test big ideas with sharp student questions. Is “God of the gaps” a fair critique? Can love and morality be reduced to atoms—or do they point beyond materialism?
