#1032 Craig Callender: The Physics of Time

Dec 13, 2024

Craig Callender, Tata Chancellor's Professor of Philosophy at UC San Diego, dives deep into the nature of time. He challenges the conventional view of time as a flowing entity, discussing the spacetime continuum and the complexities of how we perceive time. Callender examines the interplay between physics and metaphysics, addressing big questions raised by quantum mechanics. Additionally, he explores the evolution of time perception across species, emphasizing how sensory processing influences our understanding of reality.

Dr. Craig Callender is Tata Chancellor's Professor of Philosophy and a Founding Faculty and Co-Director of the Institute for Practical Ethics at the University of California, San Diego. His main area of research and teaching is philosophy of science, ranging from the nature of time to various applied social and ethical issues.

In this episode, we explore the physics of time. We talk about our intuitive model of time, and how it compares to how time actually works. We discuss the spacetime continuum, whether time has a direction, and the tensed theory of time. We talk about how our model of time develops cognitively. We discuss the relationship between Physics and metaphysics. Finally, we talk about the biggest unanswered questions in Physics.
