Nothing Really Matters - Hugh Dennis, Ria Lina, Harry Cliff and Yvette Fuentes

The Infinite Monkey Cage

Available for over a year

Jessica Fostekew and Adam Rutherford tackle one of the biggest and strangest questions in science: what is nothing? Starting with the earliest philosophers and journeying through to today's cutting-edge experiments, they ask whether true nothingness can ever exist. Joining them to explore one of science's most perplexing and important questions are physicists Harry Cliff and Yvette Fuentes, alongside comedians Hugh Dennis and Ria Lina. Together, they uncover why vacuums are far from empty, how the concept of nothing transformed science, and what the nature of absence can tell us about the origins and fate of the universe. Along the way, they delve into philosophical debates about the void, discover how scientists measure and define "nothing", and explore why the empty spaces between stars may be more active than they appear. They also role-play as positrons, deliberate over badgers, and learn that geckos harness quantum effects in unexpected ways. Our panel reveal that there is, perhaps surprisingly, rather a lot to say about nothing at all. Producer: Mel Brown A BBC Studios Production
