The history of beliefs regarding lost cities and civilizations beneath the Earth's surface is as vast and winding as the caverns of Agartha itself. In this episode we welcome Edward Guimont back to the cabin for a chat about some of the most interesting characters who have contributed to Hollow Earth thinking. Beginning with an apocryphal  tale of American pilot Admiral Byrd encountering a super-civilization of Nordic Masters inside the Hollow Earth, we cycle back to John Cleeve Symmes and his manifest destiny-style plans to conquer the Hollow Earth for the USA. Meet Raymond Bernard, the health food utopian who placed flying saucers within the Hollow Earth, Willy Ley, who wrote on occult Nazi beliefs, and Gerard Kuiper, respected astronomer who lended legitimacy to the idea that Nazis studied the sky in order to spot the movements of allied vessels on the far side of the concave Hollow Earth.  NOTES: Buy Me A Coffee https://buymeacoffee.com/wideatlantic Dr Edward Guimont on Twitter https://twitter.com/edward_guimont Dr Edward Guimont’s Website https://edwardguimont.com/ Impossible Archive Podcast https://podcasts.apple.com/us/podcast/the-impossible-archive/id1571034015 Full text of the supposed Admiral Byrd secret diary http://www.v-j-enterprises.com/byrdiar.html Pseudoscience in Naziland, Willy Ley http://www.alpenfestung.com/ley_pseudoscience.htm German Astronomy During The War, Gerard Kuiper http://adsabs.harvard.edu/full/1946PA.....54..263K
