Some ideas are:

  • You branch off into another timeline and your actions make no difference to the previous timeline
  • You’ve already taken said actions but just didn’t know about it so nothing changes
  • Actions taken can have an effect (so you could suddenly erase yourself if you killed your parents)
  • Only “nexus” or fixed events really matter, the timeline will sort itself out for minor changes
  • something else entirely

    Imagine if someone just naturally traveled through time at like… 1.0005 seconds per second… What would that look like? Would we be able to tell? Would they be able to tell? Would their perception be different?

    This is a Relativity thing, isn’t it? Like the astronaut twins sort of…

      That’s exactly like being a bit closer to the bottom of a steep gravity well.

      Yes, we could tell if they took a precise clock with them. In fact, we have to account for an even smaller discrepancy in order for GPS to work: we here stuck further down in Earth’s gravity well travel through time and extra ten milliseconds or so per year vs. an orbiting satellite.
