S4 E21 Time Travel Part I: Tenet’s Unhinged Arrow of Time

In this ambitious three-part series, we want to talk about time travel through some of our favorites ---- Tenet, Loki, and Interstellar. As viewers, we experience movies frame by frame; as human beings, we experience time through the relentless one-way time arrow. Through subverting our familiar narrative structures and disrupting causality, time travel can raise important questions about the universe we live in and its physical rules.Time Code1:43 So what is “philosophy of physics”?4:35 Time travel as a genre, and our first category of time travel stories as represented in Tenet 7:19 The logic of "traveling through time" and "changing the past"12:23 The Closed Time Loop in Tenet16:47 "bUt wHat aBouT FReE WiLl"22:10 The symmetry of Protagonist’s journey and Time Reversal Symmetry ---- where did the Arrow of Time come from anyways? ?Our GuestShelly Shi - Ph.D. candidate in UCSD, with research interest in Philosophy of PhysicsEdited ByValerie ChenSupport UsPlease consider supporting us on Patreon (in USD, suitable for listeners who live in the U.S.): https://www.patreon.com/loudmurmurs. Please consider supporting us on Patreon (in RMB)：https://afdian.net/p/e0a54e82ebd111e9bd2d52540025c377Business collabPlease reach out to us at [email protected] for any business inquiries. Listen to LMMFind Loud Murmurs in the iTunes podcast store, Google Play, Spotify, and wherever you listen to podcasts (e.g. Pocket Casts, Overcast)!
