Stuff To Blow Your Mind
本期节目探讨了真实存在和虚构的失落岛屿和大陆。节目主持人首先讨论了亚特兰蒂斯，指出大多数专家认为它是柏拉图用来阐述观点的虚构设定，而非真实存在的地方。接着，他们详细介绍了多格尔兰，一个在末次冰期后被淹没的广阔平原，它曾是欧洲中石器时代人口最稠密、资源最丰富的地区之一。节目还探讨了太平洋地区一些传说中消失的岛屿，例如特奥尼马努岛，并分析了这些传说背后的可能性。
节目重点介绍了白令陆桥（Beringia），一个在末次冰期时连接亚洲和北美洲的陆地，后因海平面上升被淹没。节目主持人讨论了白令陆桥作为人类迁徙到美洲的重要通道，以及关于其具体迁徙路线和时间仍存在争议。他们还介绍了“白令陆桥停滞假说”，该假说认为，人类在白令陆桥定居数千年后才迁徙到美洲。节目还探讨了环礁的形成，介绍了达尔文的沉降理论和先存岩溶理论，并指出环礁的形成机制可能多种多样。
