    Time Travel/ Results

    Ok, i took a philosophy class about a year ago and one of our topics was Time travel. Now, where this gets tricky, is the thought behind the results of time traveling.

    What happens if a person is to time travel, will his future change, or is it destined to remain the same? This might sound dumb, but when i watched DBZ and the Trunks saga came around, i started thinking sort of hard about this.

    In DBZ, when Trunks arrives from the future to foretell about the androids and goes back to his current time, i thought to my self shouldn't everything be completely different since he told them about the androids and traveled back to his own time period.

    But when he came back (Two Years later of the current time period) he was no different. The changes hadn't been made to his current time. He then learned that, changing the past only splits the future. Now he had created two alternate universes in which in one he foretells the coming of the androids to the DBZ crew and their future changes and his regular future where nothing has changed.

    So that's theory 1, how you can't change the future.

    Theory 2, i'll use the movie the Time Machine. In this movie, the main character tries to change the past, he wants to save his wife from dying. However even though he manages to save her, destiny always catches up to her and she'll die anyway. In this theory though, the universe doesn't split. However this theory means that what is destined to happen will happen regardless of anything interference.


    The last theory is probably the one which we're all most accustomed to due to "Back to the Future." In this theory, you can change the past and it will result in changes in the present or future.

    What really impressed me with the way they handled the time travel in Back to the future was that they took attention to detail. When Michael J. Fox's character was going on a date with is own mother, he could literally see the changes to his current time through the picture he had of his family. They went even further by even his limbs start to disappear real time due to him changing his future.

    Now, i started this thread because i'm reading this "manga" called Psyren. I don't want to ruin it, but i'm going to have to post spoilers due to the nature of this thread.

    The main characters of this series are thrown into the distant future which is a barren wasteland without knowing it. They're meant to accomplish goals in this future time to return to their present time.

    Now as the story goes on, They found out that the future is a barren wasteland due to events that will take place several months from their current time.

    What strikes me here is that the writer so far hasn't picked a theory to base this off of. Then again, the manga is only 53 chapters in. But once they go back to the present, their focused on finding the culprits who are responsible for the future events.

    What gets me here is that, every so often their thrown into the future again by a forced named Nemesis Q. However the future is exactly how it was when they were first thrown into it. It's still a barren wasteland.

    However our main characters have been getting stronger and are still on the hunt in the present time for the culprits who destroy the future. How come when they go back to the future, the future isn't different? Shouldn't their knowledge of the future and their quest to change the future, affected the future?

    Or is it that, their quest to change the future has resulted to the future's current state? It's very hard to say because at the moment the "manga" is still continuing and we haven't been revealed everything yet.

    Well, i guess i just wanted to rant a bit, but even though time travel isn't possible? Which of these theories is mostly likely possible if it were real?

    The real problem with time travel is that the Earth moves.

    Given the movement of the earth, assuming you stay in the same spot, there's only a .000822% chance that you end up on solid land after time traveling.

      Well assuming that your time machine would take that in account then that wouldn't be an issue and during development that would be a problem that would be taken care of before testing

        I'd go with Theory 2 as I think things are destined to happen no matter what.

            I got by the logic that since time travel other than constantly forwards doesn't exist, then it's not worth mulling over.

              At some point we will be able to "fast forward" so to speak by getting close to the speed of light. We will never be able to go backwards.

                It doesn't matter because only forward time traveling is possible. All you have to do is go the speed of light and you can travel far, far into the future. The problem is that light travels 299,792,458 meters per second. In comparison, the space shuttle goes something like 8,000 meters per second. The Apollo Missions achieved a speed of around 11,176 meters per second (25,000 MPH) and that is the fastest a human has ever traveled. So we're not even remotely close.

                  It's kind of like "Oedipus". He found out his fate and tried to change it but it was impossible since it was inevitable.

                    I've always thought that whatever a hypothetical future time traveller did in the past was what caused the future to be whatever it was.

                    If I went any bigger, it would not have properly fit with my equipment, so I had to optimize. I'm okay with it, but I also know what I'm missing with those five inches. :)

                        I'm not sure if I'm alone here, but I don't want to(not to mention I probably won't be anyway) around if/when they find out how to travel into the future.

                          They already know how to do it.

                          We just have to figure out how to go that fast.

                          We can actually speed up an atom up to .99999 percent of the speed of light.

                            I don't believe in Time Travel. This life is it.

                              You may not want to, but if someone traveled to any time in your lifetime, wouldn't you have to live that over again?
