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

    But my question was if it was possible. Not do you believe it’s possible.

      You’re right.

      It would have to be multiple timelines or single consistent history. Of the two, I think multiple timelines is a little more likely.
