    My theory is that, just as Einstein demonstrated that forward time causality can only happen at a rate of Distance/C, and that two event separated by that amount of distance/time would appear to be simultaneous to any observer.... I think there might also be a relativistic approach to resolving time travel paradoxes.

    My idea is that, when sending information back in time, there's a "one time interaction law" which states that you can never interact with the same event (where an event is defined as a four dimensional location) twice. Hence, if you grandfather conceived your father during a night of hot steamy sex with your grandmother, you're one interaction with that moment in history is already over, and you can't ever travel there again if your goal is to interact with it. (You could watch but.... I would advise against it...... if only for your own sanity sake.)

    However, if you want to go talk with a martian who lived on a far away world 10,000 years ago, you can feel free to do so. It's not your own history you are changing. It's someone else's history. (Maybe there are some alien cultures who interact with one another in the other's history, but from their own present..... just imagine how that would pan out..you could end up getting dominated by a culture that is younger than you are.)

    What "force" would prevent you interacting/interfering with them?

    I know that you mentioned that there is a law but how is it enforced when you are a human as well but from the near future? How could nature "know" you're the one and instrument ways to stop you?

    This is the question that has involved the most thought for me. Right now, I think of it as a quantum mechanics type of problem.

    If you pass a single photon through a double slit apparatus, and put a detector on the other side, that photon will somehow always manage to avoid striking locations on the detector where cancellation would have occurred if two photons had been sent simultaneously, instead of just one. It's like it knows in advance.

    Well, the firing of synapses in your brain involves a lot of photons. I know it seems silly to think of things that way, but photons are the only truly random thing known to exist in nature, and yet even they avoid certain contradictions.


    How could nature "know" you're the one and instrument ways to stop you?
    Because nature doesn't have a past present or future, just one big eternal "now". Your next decision is only in the future from your own perspective, or others who share your temporal perspective.

    From nature's perspective, your next action is just as much in the past as it is in the future.
