    Maybe this is pseudoscience. At least it takes the form of a hypothesis so I thought I'd post it here.

    My hypothesis is that maybe time machines are real and/or will be invented someday, so people with the right kind of personality can find loopholes in the space-time continuum that allow their future self to come back and help them out in some rare situations. Under that theory, the afterlife would be the result of a future generation deciding to visit the past and rescue us from death (in a way that doesn't change history - such as leaving our corpse and just saving our consciousness.... or something like that.)

    When a person's spirit "goes into the light", they move irreversibly into that future time frame and cannot return again, unless their role is limited to observation, or their actions would conform to the expectations of the people in the present (who mostly expect the dead to stay dead right now.) If they stay behind as a ghost, they are limited in the degree to which they can interact with their surroundings because their continued existence has been caused by a time traveler, and they must avoid contradicting the events that lead up to that time traveler's decision.

    Certain figures like Jesus Christ, or Moses may have such a force of personality that they could be totally assured of remembering and wanting to come back in time at a future date to bring miracles to completion. For example, maybe Jesus Christ's future self is going to come back in time to the wedding he was at where he turned the water into wine, and use a teleportation device to teleport the water out of the jars, and teleport wine into them instead. Because the decision was made prior to the result, there is no temporal contradiction. His future self's decision to come back and do this is not based on a memory of the event having transpired differently and wanting to change it. Nor is it the result of the event going right. It is being caused by the decision he made a moment before hand, when the jars were still full of water.

    That's the main limit of time travel: causes must be independent of results. A result cannot be its own cause.


    Some clocks are only right twice a day, but they are still right when they are right.

    I'm not sure if the grandfather paradox will prevent a theory like this. If you back in time and murder your grandfather then one of your parents will not be born, and neither will you. I prefer a sun paradox. Our middle aged sun will one day enter old age and become a red giant. Any humans still alive on Earth could temporarily escape to Mars, or maybe they could jump into a parallel world, or they could travel back in time to when the sun is less threatening. Even if they could back time travel they would have to meet the sun well before its death phase. So it is not just the case of travelling back on planet Earth.The only alternative I know is that right now someone in galaxy far away is reading this very post on the same Science Forum, and that person is YOU. Or so I'm led to believe in cosmology's darkest secret.

    Everyone always assumes that the two problems are mutually exclusive. What if both A) - Causality is Immutable and B) - Time travel is possible in reverse?

    A complex set of rules could exist wherein you both A) - Can travel back to a time prior to your father's conception, and B) - Cannot kill your grandfather while you are there.

    QM allows for some very interesting situations. Consider Schrodinger's Cat. You've got a dual state where the cat in the box is both alive and not alive, which is settled only when an observer actually looks in the box to see which is true. At that moment, a random decision is made as to whether the cat was dead all along, or was alive all along, but prior to that moment both states were equally likely (and therefore equally true in QM). Suppose you design a machine that is capable of influencing that decision in the direction of your choosing instead of leaving it to chance, and use this machine at the moment of observation. Effectively you would be deciding whether the radioactive isotope in the Geiger counter had decayed or not. However, there would be a zero chance of creating any temporal paradoxes.

    Schrödinger's cat - Wikipedia, the free encyclopedia

    Maybe time travel operates within those limits. You can only choose outcomes that are contained in systems that are isolated from the system that caused your own existence. Ie. you can only choose what will turn out to have happened inside the box.
