A paradox is just an unanswered question. There's two views that I think are most probable relating to time travel, one being that you simply cannot change the past. You might go back in time with intent to change something, but the fact is, it never happened, so you didn't change it. This is of course, assuming that there is merely one timeline. The most widespread example of the time paradox is going back in time and killing yourself. Most people say, "Well, if you killed yourself, you can't go back in time to do it, so you're still alive, so you go back in time to kill yourself..."
This explanation is far too overcomplicated. If you're still alive to use the time machine, than you never kill yourself. Perhaps you go back in time, but you do not end up killing yourself, regardless of what happens. Maybe you change your mind, or something stops you, but you cannot change that which has already happened, even if you can go back to the point at which it happened.
My other opinion, and the one I favor of the two, is much like from the book Timeline. There's multiple timelines. If you go back or forward in time, you are no longer in the same dimensional parallel from whence you left, you are now in a new one, going either slower or faster than the one you left.
The way Timeline expresses it is that there is an infinite amount of paralell universes, each one different than the others no matter how small a difference it is. One is exactly the same as ours, but a second behind. Another is two seconds behind, another three seconds, et cetera, and I think this to be the most likely possibility. Therefore, if you go into a parallel universe behind ours and change something, you're not changing your present, you're changing their future, something quite different than your present.

Backwards time travel cannot be achieved from what I understand, but you can "travel" forward in time through some form of gravitational or velocity time dialation (where your frame of time would go slower than other parts of the universe,) although you wouldn't be able to return.
|
That assumes that there is only one timeline, and you are not travelling through dimensional parallels, though...
But anyway, think of it like this.
You're driving in a car on the highway, and lets assume that everyone is a law abiding citizen going at the same speed, and we'll say it's moderately fast. Maybe 30MPH. Now, if you and only you slow down, the other cars appear to be going faster than they were, even though they were going no faster than you were previously. The more you slow down, the faster they appear to go. Once you go so slow that you stop, you can even begin to go backwards, and they'll still appear to be getting faster and faster.
But, however, let's assume you're going forward again. You start driving, and eventually reach a speed so high that the other cars appear to be standing still. It's quite possible.
Because we have an infinite number system, we can argue that speed is infinite. You can always go a little bit faster. Not in a car, granted, all vehicles today have limits, but what I mean by that statement is that there is no maximum speed.
There is no speed where all vehicles stop accelleration, and thus it can be argued that you can go so fast as to reach the other end of the spectrum where the other cars appear to be going backwards.
Now I'm sure you've long known where I was going this, and can relate your car to a time machine, and the other cars to the rest of the world, so I doubt I need to do that for you.

We don't have destiny. Every instant in our everyday lives leads to an infinite amount of "paths" which we continue to live. It might be possible to go back in time, but if you change something there (which is inevitable) then that time takes another, completely new, path, which you can only experience by living that same time. In the time where you came from, everything is normal, and your actions in the past have changed nothing.
Here is something I drew with Paint....(lol)
http://www.n00bstories.com/image.view.php?id=1077728031
Every path will lead to infinite number of paths, which will again lead to infinite number of paths and so on. If you go back in time, you go back in that tree-like structure as in the image....but when you change something in the past you're in, it takes a new route from the spot you're in, but all the other routes remain the same.
Take the picture for example. If you go from spot 1 to spot 2, you just create another timeline, and ONLY that timeline has been modified by your presence. Note that also that timeline spreads, and your actions will affect all the timelines spreading from it, but you will not change the actual time you were originally in...
Phew, so complicated to explain, but that's my 20 cents.....
There's a hole in the sky through which things can fly.

No matter what the true outcome is, all theories of time travel say that modifying the past cannot affect your present, in order to avoid the time paradox.
So, the only thing we could use travelling into the past for is for information and entertainment, right?
Even so, it could create chaos. Just imagine...A good portion of the world believes in divine creation, and another good portion believes in evolution. If you could go back in time and prove one, one way or another, I highly doubt that the people who were wrong would just say, "Oh. Okay then." Not saying that they'd revolt, but there was a lot of hostility just when teachers began teaching evolution, it could be quite worse if it was proven right or wrong...

I was talking to my friend about this and I now believe there is no such thing as time travel. He simply said "there is no such thing because if there were people from the future would have traveled back into our time by now". That makes perfect sense and makes me believe there is no time travel. Unless your theory of multiple parallel universes is true, with the fact that we are the first of the multiple universes and there are no future universes at this time but that makes no sense.

If you cant change the past like your saying then it proves time travel is not possible. A person appearing in a time machine changes the past. If you cant change the past than that cant happen. So therefore you cant time travel.

1. If you can change the past: Time machines would not be open to the public. If you could change the past, time machines would have to be VERY strictly regulated, imagine what horrors could be done.
2. If you can't change the past: It's obvious, then, why we haven't seen tourists: because us seeing them would change the past.
|
1.Did you mean to say "Time machine" How would this be kept private? Sooner or later an "insider" would expose that it is possible.
2.What is stopping me from seeing these "travelers"?

Well, there's two possibilities for the effects of time travel (Either the past can be changed, or it can't), and each one has an explanation for why we have not seen travellers from the future.
If it CAN be changed:
1. If someone was intelligent enough to develop a method of time travel, and they tested it and proved the theory that allows for the past to be changed, then they would hopefully know enough to know what horrible things could be done. People could exploit it to a horrible extent, so either the person who created it would be smart enough to destroy it, or keep it under very, VERY tight security. It would be infinitely more powerful that the most destructive bomb we have, because it would be untraceable.
If it CAN'T be changed:
2. Well, obviously if the past can't be changed, then people of the future could not change their past by affecting our present. There's several reasons of how this would work:
1a. It's corny, unlikely and unprobable, but they're "hiding" from us. I don't think that's the correct reason, but it's possible.
1b. They can't reveal themselves because of Scythar's "tree" theory. We're progressing in a branch of the space-time continuum in which people from the future do not travel back in time, and if they do, that timeline branches off into a new branch of time.
As for what I meant by travelling into the past but not being able to change it, have any of you read the book or seen the movie Time Machine? If the theory of there being but one timeline is true, than you cannot change the past. Maybe you can travel back to it and live through it, but anything that you try to change will correct itself, through whatever means.

If you're assuming that you can't change the past, then you can't have a person in you're example change the past...

I love thinking about time travel(its good exercise for the brain  ) I don't think its possible, if time travel was some thing that could be done, why haven't we been bombarded w/ "tourists" from the future? And if time travel was possible(its not  ) you could NOT meet yourself, you can't be in two places at once.
|
I could give several reasons:
1. If you can change the past: Time machines would not be open to the public. If you could change the past, time machines would have to be VERY strictly regulated, imagine what horrors could be done.
2. If you can't change the past: It's obvious, then, why we haven't seen toursits: because us seeing them would change the past.

Thats true. I always said if time travel ever did exsist, we would have to set some boundries or some kind of time laws to make sure nothing affects the future.

I was talking to my friend about this and I now believe there is no such thing as time travel. He simply said "there is no such thing because if there were people from the future would have traveled back into our time by now". That makes perfect sense and makes me believe there is no time travel. Unless your theory of multiple parallel universes is true, with the fact that we are the first of the multiple universes and there are no future universes at this time but that makes no sense.

Hey I always say, ANYTHINg is possible. All it takes is time and patience.

It has been theorized that the reverse flow of time caused by achieving a negative velocity can also be attained by travelling at the hypervelocities of light. Therefore, theoretically, backwards time travel is possible.

Here's some more bait to nibble on. Wtach the movie "Time Cop" with Jean Claude Van Damm. It has an interesting reason as to if time travel is possible, why we haven't been visited from the future, and what will haven if we literally make contact with our former selfs.
|
I was thinking the same thing. Imagine if there is some Time organization that is used to stop time bandits or time criminals. Thats why I said, if we as human ever did create a way to travel back in ime, we would have to set some boundries or laws on what we can do. But thats IF time can be change by going to the past.

it would be funny if in some perelel universe that story is true. i thought time moving backwords on perelel universes was conciderd imposible.
