In this episode we speak with Frank White, a space philosopher. Frank has coined the term ‘The Overview effect’ which describes the awe-inspiring experience of viewing the Earth from space. He has found that with great consistency, this experience profoundly affects space travellers’ perceptions of themselves, our world, and our future. He talks to us about the magnitude of overview effect experiences, sustainable space migration, and why all his narratives aim to create a sustainable future on earth. Frank also suggests we need an 18th UN Sustainability Development Goal: Space.
