hahah i just said this in my faster than light topic. This is a topic that will drive you crazy trying to figure out.
Said person steps off the track, changes history, but then again if they went back in time it would have already happend anyway so it can change history as it would have happend before even going back in time essentially so therefore it was what was supposed to happen:)

Now this is a topic that will start me off in an instant.

It is possible to time travel. However, you'll have to consider these factors before you head of into your trip back in time.

[The Grandfather Paradox]

No, I do not mean by old father time. A good example of the grandfather paradox is this:

Imagine you hate your grandfather. You have the tendancy to kill, but the cops will find you. So, you hitch a ride back in time to kill him when he is young and not married.

If you killed him, then you will not be able to exist in the future. Therefore, you will not be around to go back in time to kill him.

Then your grandfather lives because you were not around to kill him. Then you are born in the future and you start hating him at some point.

The cycle will repeat until an outside force stops you. However, no one knows how this outside force would be like.

[another paradox]

Imagine again that you do kill your grandfather. However, you find out that you are still alive. How is this possible?

The answer.........You have accidentally traveled to another dimension.

There's a huge risk involved when it comes to this.

Traveling from one dimension to another is like throwing a dart at a spinning dartboard. You are the dart and the individual markings on the board are the destinations.

Not only that, you have absolutely NO control as to how fast the board could spin. Thus, resulting in the fact that you have no idea as to where the hell you would end up.

Now, about that fact that you still live after killing. Chances are, that your "Alter Ego" [other self] is on his way to kill HIS grandfather, but you did the job for him. Therefore, he can't exist anymore. AT ALL or NEVER because you are the outside force in your Alter Ego's dimension.

Now, let's say that you wish to be the only Alter Ego in the entire multiverse [multi-universe]. There, you would start planning on traveling to another dimension [all of them] so that you could kill your other Alter Ego.

But WATCH OUT!!!!!!! Chances are, your other self could be planning on doing the same damn thing to you. So, wear a bullet-proof vest.

Well, Jared.

Even if people did come back in time to us, they will NOT be willing to tell you that they are from the future. Instead, they will disguise themselves as regular, everyday people of our time. Remember what Pippin said? Anything you do in the past will effect the future.

Not only that, they are probably here as time-traveling tourists.

Here's a tip. Go to any place and see if you could talk to someone [anyone]. If that person refuses to even speak to you and you see that the person is not speaking to anyone or doesn't have a home, then there is a 25% chance [or less] that he/she is a time-traveling tourist.

I think time travel is impossible. Which is why you should ALWAYS think BEFORE you act.

Did you really?  Maybe you just think you did, but have actually travelled through a wormhole and have appeared before the program began.  You may watch it tomorrow, but only think you did tonight...

The grandfather paradox just delays time it does not actually go back in time.
