In this episode, Angus interviews Colin Sellers, a land surveyor and expert in catastrophism. They explore the concept of catastrophism, which posits that Earth's history is marked by significant, rapid changes due to catastrophic events, contrasting it with the gradualism of conventional scientific views. The discussion delves into historical evidence, the work of Randall Carlson, and the implications of catastrophism for understanding climate change and geological history. The conversation emphasizes the importance of considering all evidence, including ancient myths and modern scientific findings, in understanding our planet's past and preparing for future events. We delve further into various themes surrounding earth curvature, the implications of catastrophism, and the exploration of geological phenomena such as Bonneville Lake and the Yellowstone caldera. The discussion highlights the importance of personal inquiry in understanding scientific concepts, the evidence of catastrophic events in geological history, and the merging of education with adventure through the concept of 'adventurology.'
