Wormholes

Wormholes

Author: BBC Radio 4 October 24, 2024 Duration: 1:00:56

Melvyn Bragg and guests discuss the tantalising idea that there are shortcuts between distant galaxies, somewhere out there in the universe. The idea emerged in the context of Einstein's theories and the challenge has been not so much to prove their unlikely existence as to show why they ought to be impossible. The universe would have to folded back on itself in places, and there would have to be something to make the wormholes and then to keep them open. But is there anywhere in the vast universe like that? Could there be holes that we or more advanced civilisations might travel through, from one galaxy to another and, if not, why not?

In Our Time is a BBC Studios Audio Production


For anyone with a restless mind, the weekly In Our Time podcast from BBC Radio 4 offers a deep and engaging conversation across the vast terrain of human thought and experience. Host Misha Glenny guides a panel of distinguished academics, not in lecture format, but through a lively, accessible discussion where ideas genuinely collide and unfold. You might find yourself immersed in the complex legacy of a figure like Napoleon one week, and the next be untangling the scientific principles of photosynthesis or the philosophical arguments of the Enlightenment. The scope is deliberately broad, covering history, religion, culture, science, and philosophy, because understanding one often requires context from another. What you hear is the genuine process of exploration-the questions, the debates, and the connections made in real time by leading experts. It’s the kind of podcast that doesn’t just recount the Sack of Rome or the intricacies of Russian court politics, but examines why these moments mattered and how their echoes are still felt. The result is a consistently stimulating hour that treats listeners as curious equals, offering the intellectual satisfaction of following a great conversation to its illuminating conclusion.
