Many of history's greatest scientists considered their work to be a religious endeavor, a direct search for God. Pioneers like Newton, Copernicus, and Galileo believed that their discoveries told humanity more about God's nature than had been known. Beginning in the early 18th century, science and religion came to be at odds — the gap widening most famously with the publication of Darwin's On the Origin of Species. In recent years, a new dialogue has begun, driven by leading scientists across the world. Host Krista Tippett explores with three scientists, each of whom is working in a field that's rapidly advancing our understanding of what it means to be human. From very different perspectives, they suggest that our most sophisticated 21st-century discoveries may be driving us back to questions of faith.
