A bestselling French engineer argues that modern cosmology points to a Creator — but a leading physicist says science explains it all without God. Unbelievable? podcast John Nelson hosts cosmologist Dr Niayesh Afshordi and entrepreneur, co-author of God and the Big Bang and engineer Michel-Yves Bolloré for a lively clash on cosmic origins. Afshordi outlines ideas that our universe may have emerged from a black hole and surveys competing models of the Big Bang. Bolloré, co-author of God: The Science, The Evidence, argues that twentieth-century discoveries - from thermodynamics and entropy to expansion and fine-tuning—stack up as evidence for a Creator. They test “beginning versus eternity,” debate whether fine-tuning signals design or selection effects, and ask what constitutes prediction, falsifiability, and proof. Is the “God hypothesis” scientific, metaphysical, or both? Can science ever answer “why there is something rather than nothing”? Thoughtful, spirited, and friendly, this episode brings faith and physics into constructive dialogue.
