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

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 Code

  • 1:43 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 Tenet
  • 16:47 "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? ?
