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

    I have a unified theory that includes bits of everything.

    • it’s possible to communicate in the same timeline between the future and past by using gravity (think something like Interstellar)
    • By using gravity as an nondestructive line of communication, it’s possible to change events in your current existence without a causal shift or split.
    • by sending actual matter into a timeline either ahead or behind where it’s supposed to exist it causes a causal shift or split in the timeline. this means you will never be able to see the future and can only contaminate the past enough to damage your present causing an inverted negative effect to your going back in time anyway.
    • nexus events can only exist when it has a high gravitational marker attached to it. eg: a star will always go supernova, when doesn’t matter as much as the fact that it’s unstoppable because the gravitational function it applies on a universal scale across all timelines, known and unknown. think of it like flashing a flashlight into a room filled with mirrors. each mirror is the physical plane of existence for the timeline (the beam of light). the beam will hit the first plane and then bounce off all the others in the order in which the photons scatter. if you could slow down and witness the photons, they wouldn’t all hit at the same time nor at the same strength.
    • It’s only possible to communicate across time using gravity and only if someone has picked up the “receiver” in the past. meaning if we’re not listening for the call “now”, we will never receive the call from “tomorrow”. I think this type of communication is completely within the reach of our technology today and quite possibly is being used today without world knowledge.
