Tim Maudlin is Professor of Philosophy at NYU and Founder and Director of the John Bell Institute for the Foundations of Physics. This is Tim’s eighth appearance on the show. His second to last appeared on episode 246 for a masterclass on Albert Einstein’s theory of general relativity, explaining it from the ground up and elucidating some common misconceptions. In this episode Tim returns for a discussion of the philosophy of time. More particularly, Tim and Robinson discuss black holes, fundamentality, simultaneity, time’s flow, rate, and limits, connections to physics, time travel, and more. If you’re interested in the foundations of physics, then please check out the JBI, which is devoted to providing a home for research and education in this important area. Any donations are immensely helpful at this early stage in the institute’s life.
