What lies at the center of the Earth? Is it a massive ball of molten rock? Is the gate to Hell down there? Is it hollow? This week we discuss Hollow Earth Theory and its various explanations. We also talk about early science that led to the hollow theory, as well as some of the more...questionable sources behind the theory. We also talk about lost civilizations that could be dwelling inside Earth, hollow Earth theorists turned fugitives, and brand new Dyson™ Brand Globular Dyson Sphere™.
