Time Travel?

Question

If time travel where possible would you be able to change history?
My theory is that you would not. Anything we know about what has happend, will have happend. It would then not be possible for it not to have happend.
Debate please.

Answer 1

I agree. Whatever past changes will not be noticeable to present tense since the past will always be the past.

Remember, all tasks to change the past will always fail. Let's say I want to go back in time and exile Hitler to Siberia before he causes any trouble. I know I fail before I even try because I have a motive to time travel, the event I want to change still exists. If I did go back and change it I would undo my going since I need the motive to go in the first place.

So in the end movies like Back to the Future are a load of crap. No fading photos and newspapers here folks. If you even manage to mess with the timestream you'll never know you did.

Answer 2

Time travel is part of the Space Time Continum and part of Einsteins theory of relativity. That makes Time Travel Actually possible. If you went say a million miles out into space and then looked back at the earth you may see events that took place several years ago.

Having said that, changing history would have odd consequences. If might result in you disappearing from existence especially if the history you changed was family history.

Answer 3

Time travel need not be in the physical sense to achieve the same goal.The future may have already changed or the present but you or others around you don't know the difference unless you were involved. See Remote Viewing and psychic spying. They can change the future and so can others just by their own common sense. There may be some natural events that will be harder to change what will effect the majority. Insight can come from knowing history and science.

Answer 4

I agree with you. I think if you went back in time, you couldn't kill your grandfather and prevent your own birth, because, well, you already didn't. Some people conclude from this that time travel is not possible and they may be right, but I think it also means we don't have free will. I think the future is just as unchangeable as the past, we just haven't found out yet what will happen.

Answer 5

Just out of curiosity how many of these answers are based on "Back to the Future" Well mine will be as well, except not the first one, I think the second. Yes you could change the past and cause an alternate future(present) As in the movie it would be different time lines - and no, you couldn't kill your father and cause yourself to never be born(like the first one) - nothing like the movie Frequency - think different time lines - not a straight line

Answer 6

It is possible that some time travelers have gone to the past to meddle with it, and we possibly have them among us now from the future, trying to change the course of the future.So the cycle goes on and history eventually takes its course.

Answer 7

“The Grandfather Paradox [where you go back in time and kill your grandfather] is not an issue,” said Mallett. “In a sense, time travel means that you’re traveling both in time and into other universes. If you go back into the past, you’ll go into another universe. As soon as you arrive at the past, you’re making a choice and there’ll be a split. Our universe will not be affected by what you do in your visit to the past.”

The Butterfly Effect Theory ( http://en.wikipedia.org/wiki/Butterfly_effect ) could mean that changes in the past could ripple into many timelines like a time tsunami.

Aledged time traveller John Titor ( http://johntitor.com/ ) told us of our future, but some things changed ... other predictions came to be true.

Answer 8

Hi. For a pretty good sense of how history is hard to change watch the movie "Frequency". One small change would lead to a cascade of small changes that would add up.

Answer 9

the closer you get to the speed of light the more time appears to slow down so logically if you pass that speed it will go backward?
if this is true i believe you can observe the past but not interact with it. much like the way see stars in the sky that are so far away that when the light gets to us we are watching what happened millions of years ago.

Answer 10

By definition you can't go back in time. Forward time travel is easy. Didn't you posted this tomorrow?
