If time travel existed...
How do you think it would work?
From what I noticed, most movies and shows have one of these two approaches to time travel;
Being able to change the present. Like in Looper, where if you went back and changed something, it would effect the current present. This concept kind of confuses me, I mean, it should make more sense because if you went back and done something differently, naturally you would expect your presented to be affected depending on your actions. However in Looper, they used time travel to send your older self back to be killed by your younger self, so when you done that, then got old once again, would your younger selves keep killing your older selves? Will there be never ending yous and keep living different lives each time?
Then there's the whatever you done while time traveling, had already happened, and you cannot change the present no matter what, approach. I think I like this one more, because while you're experiencing it for the first time, you weren't aware that you actually played a part in what happened in the past. Seems more interesting to me and less confusing, because it doesn't matter what you attempt to do while time traveling, whatever had happened, is inevitable.
So, if time travel were to exist or if it were to be invented, how do you think it will work? Like one of the two examples I listed, or something different altogether?

(cont.) But there are supports (even Einstein acknowledged that traveling into the past is possible---and not just "slowing down time at incredibly fast speeds" but legitimately going into the past and having the ability to alter the future (but, again only possibly). Who knows whether going back into time would have an effect on the future, some believe that going back into the past and altering events would lead to a separate universe and timeline (this happens in Dragon Ball Z, Future Trunks goes back and prevents Goku from dying and makes sure the androids don't rule the world---but his timeline where Goku and the other fighters are dead and where the androids did have a reign of tower is not destroyed, just merely a separate reality). Others believe that when you go back and alter the past, there is no separate continuity, and you directly affect the future. A physicist on "Universe" (a space show on History 2) was talking about time travel, and said--hypothetically--he could go back in time and prevent his grandparents from ever meeting, and that could effectively prevent his father or mother from being conceived, therefore wiping his existence off the face of the universe. [b]Or[/b] another possibility, according to him, was that he could try to alter the past as much as he wants, but the natural order of the universe would "adjust" his actions so the net effect would be the same. So each time the physicist I mentioned previously prevents his grandparents from meeting, the natural order of the universe will make it impossible for his grandparents not to meet and marry each other. The movie "The Time Machine" used the latter theory when, each time the protagonist tries to go back in time and prevent his fiance from getting killed, she inevitably dies one way or the other, no matter how many times he tries traveling in the past and tries to protect her. But yeah, the most feasible option most scientists think to "time travel" is to go at or near the speed of light or go around a massive black hole to experience the altered space time, which I guess, in a sense, is probably considered time traveling, but the old time machine and going into the past, no one really knows about that (for now).
