What if an advanced civilization existed on Earth millions of years before us—and we’d never know? Astrobiologist Adam Frank and NASA scientist Gavin Schmidt explore the “Silurian hypothesis,” imagining how past civilizations might have left chemical traces in the geological record, much like our own carbon emissions and plastic pollution. They ask: could we detect such a footprint today, and what would it look like? While tectonic shifts and erosion make ancient evidence hard to find, modern pollutants may offer clearer markers. This thought experiment challenges us to consider our own impact—and how fragile our legacy might be. Listen in comfort: Get a discount on a Soli Pillow: http://solipillow.com/discount/dnn.
