MinutePhysics (which, if haven’t checked out already would be worth spending a little of your time on) and a fun whiteboard explainer on the different types of time-travel in various films and books. Specifically, the video synopses how time travel causally affects the perspective of charactersâ€™ timelines (Who has free will? Can you change things by going back to the past?).
I appreciate time travel stories that have a nice logic to them. I have to agree with Henry Reich when he says that, “Logical consistency is a thing that you may have noticed I think lays the foundation for good time travel stories.” Which explains why I didn’t like Star Trek: First Contact or the Original Superman.
