The point of this article isn't so much to prove some theories incorrect or impossible. As time travel doesn't really exist we cannot say anything about it and say its a fact. Its about logic. If you are making a movie about time travel, than do it the way it makes sense. There are to many movies this days that employ some kind of time traveling mechanics which make no sense at all. Instead of using time travel as a good plot device, it is more and more used as a deus ex. Writers aren't able to think of better ways to resolve the plot. Don't you just hate it when that happens. Oh, no, the main character died, its all over, the ship is destroyed and the world has ended. But no, wait! What's that? Oh, its OK. We managed to go back in time and prevent the tragedy, and now we can all go on with our lives forgeting that we just found a way to travel through time. Now that i think about it, there is not a single movie including time traveling that hasn't got some kind of a plot hole. But that's ok, as you said, its a movie and it doesn't have to be all real. But it has to have some sense and meaning. Using time travel as a main plot device where it is not necessary or even sane, is a serious crime. The actual act of time traveling isn't that important, or the science behind it. There are many theories and no one can say one is the best. A far far more important aspect is how you handle the story and the world after the actual act. Its easy to think of a functional super cool futuristic time machine, but it is hard to think of what to do with it once it is actually there.
