Time Wars & Alternate Timelines

Isaac Arthur・36 minutes read

Time travel and alternate timelines are popular themes in science fiction, sparking curiosity about invading and conquering the past. Despite its prevalence in fiction, the feasibility of time travel remains doubtful, and philosophical debates on identity and free will arise when considering the implications of altering history irreversibly.

Insights

  • Time travel in science fiction explores various "What if" scenarios and the implications of altering timelines, sparking philosophical debates on free will and identity.
  • The concept of temporal inertia, discussed in relation to time travel, suggests a self-regulating mechanism to prevent paradoxes and maintain attractor states in history, potentially leading to catastrophic outcomes in time wars.

"Temporal Inertia in Time Loops"

  • Time loops must close back on a point to maintain the actor's initial state of mind or events.
  • The loop continues with minor changes until self-correction is achieved.
  • Electrical resistance analogy is used to explain loop behavior after a certain number of events.
  • Temporal inertia, as favored by Isaac Asimov, plays a role in self-correction.
  • Inertia ensures events tend to happen as they were meant to, with attractor states in history.
