There's nothing beneath our feet besides thousands of miles of rock, soil, and molten metal, right? Maybe a handful of wriggling sightless creatures who pose no threat to the likes of us. But what if there is so much more? Rivers, vegetation, even a small star... all of the necessary ingredients for life, and perhaps thriving, advanced civilization. On this episode of The Age of Enfrightenment, your hosts take you on a journey to the center of the Earth,\ and the center of a storied tradition in scientific thought, that seems to be ripped directly from the pages of science fiction.
