He is also the host of Sean Carroll’s Mindscape, a podcast about science, society, philosophy, culture, arts, and ideas. This is Sean’s fourth appearance on the show. He appeared with David Albert of Columbia University on episode 106, which covers the Many-Worlds theory of quantum mechanics, Boltzmann Brains, and the fine-tuned universe. He was also on episode 118 with Slavoj Žižek on quantum physics, the multiverse, time travel, and a whole lot more, and then episode 200 with Daniel Dennett and Steven Pinker on AI, parapsychology, and consciousness. This episode is coming out in advance of Sean’s next book, Quanta and Fields: The Biggest Ideas in the Universe (Penguin, 2024), which will be released on May 14, 2024. Sean and Robinson discuss many of the topics and themes of Quanta and Fields, including the books’ namesake subjects, as well as more decides, like scientific realism, free will, the simulation hypothesis, and the end of physics.
