Today’s episode is a little different from normal as we’re going to begin a short series sharing a recent conversation John had with Lord Martin Rees, the astronomer royal. As well as a highly distinguished cosmologist and astrophysicist, Martin is also an author whose recent books have explored some themes familiar to Matters of Life and Death listeners, including the rise of artificial intelligence and the future of humanity.


Their chat was first broadcast as part of the Big Conversation podcast, hosted by Justin Brierley, which is also part of the Premier Unbelievable network -
