We are a physics podcast. But not just that - interviews with scientists, scholars, authors and reflections on the history and future of science and technology are all in the wheelhouse. Over the years, for over 200 episodes, we've had shows on the astrophysics of stars, a comprehensive history of nuclear fusion, thermodynamics, particle physics, climate change, economics, philosophy, the psychology of conspiracy theories, and even the lives of Louisiana Senator Huey Long, or scientists under Stalin in the Soviet Union. 

We are an independent show: everything you hear is created by one person out of passion and love. My aim in producing this show is never to talk down to people, but instead to discuss fascinating and vital subjects with scientific rigour, compassion, and an eye for narrative: to educate, inform, and entertain. I hope that you, the listener, will find something you like here. 

You can read about us here, which includes a comprehensive episode guide for new listeners covering all of the shows that we've done, as well as links to transcripts of many of the episodes.  

You can contact us here - everything goes through to my email and I try to answer each one. Your comments and questions help me to improve the show and also motivate me to carry on, so I highly appreciate reading anything you feel like sending. 

If you like what we do and want to help us keep doing it, you can donate here. I am extremely grateful for those of you who have done so. 

You can also subscribe to the Physical Attraction: Extra! Feed over at Patreon: www.patreon.com/PhysicalAttraction - where for a small fee per bonus episode, you can help to support the show, and get some juicy bonus content too. The Patreon includes unique bonus episodes that stand alone, or alongside our existing series. But you will also get episodes as soon as I finish producing them, which is often months in advance: so, if you can't wait for your fix, that's where to go. 

We had a sister podcast, Autocracy Now, which deals with the lives of famous historical dictators. You can find some of their episodes on our feed, or the show itself at www.autocracynow.libsyn.com

Lord Martin Rees on Catastrophe, Cosmology, and the Future

Jan 1, 2021

Sometimes in this game you get to do an interview where you genuinely can say: "the person I'm about to interview needs no introduction." This is one of those occasions. But if I were to do that, it would wreck the fun of getting to introduce the interview, and why would I deprive myself of that?

So, this episode, we are interviewing Lord Martin Rees. Martin Rees is one of the foremost cosmologists and astrophysicists of our time. He was made the Astronomer Royal in 1995, has been Master of Trinity College Cambridge, and President of the Royal Society. He has written more than 500 research papers across various areas of astrophysics and cosmology, including contributions to the origin of the cosmic microwave background radiation, the final proofs of the Big Bang theory, quasars, and gamma ray bursts.

In the latter part of his career, he has been an immensely influential populariser of science, writing books on Cosmology such as Just Six Numbers and Our Cosmic Habitat. And he has also devoted himself to considering grand problems of the future of humanity and the existential risks that we face: his book, Our Final Century, helped to kick off the field of existential risk studies, and he co-founded the Centre for the Study of Existential Risks at the University of Cambridge in 2012.

It is no exaggeration to say that a great many of the ideas that we've discussed on this show - and my own personal inspiration to study physics in the first place - owes to the work of Lord Rees, both in discovering much of the science in the first place and then again in popularising and explaining the ideas so wonderfully.

I was extremely grateful that he was willing to be so generous with his time and respond to such a large range of my questions. Our interview touches on existential risks, the current pandemic, extraterrestrial life, cosmology in general, and the nature of fundamental physics.
