In this episode of pplpod, we explore the remarkable life of Alfred Wegener, the meteorologist and polar explorer whose theory of continental drift was mocked for decades before becoming one of the foundations of modern Earth science. The episode follows Wegener from his early work in astronomy and meteorology to his dangerous balloon flights with his brother Kurt, where he developed a way of thinking in planetary systems rather than isolated pieces. That outsider perspective helped him see what many trained geologists rejected: the continents were not fixed in place. By comparing continental shelves, matching rock layers, fossil plants, and geological structures across oceans, Wegener argued that today’s continents had once been joined in a single ancient landmass, what we now call Pangaea.

The episode also examines why Wegener’s theory wa ...
