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

      “An unidentified man in SS uniform reportedly tried to kill Hitler during a rally at the Berlin Sportpalast.” 1939

      This was definitely the time traveller.

      LOL. I knew there were a lot, never looked it up! The problem is, in the time travelling paradigm, those would fit in the self-mending timeline end of the theory. This version would simply have many dead hitler. Like schroedinger’s cat or photons or whatever.
