id change my past, the butterfly effect would still happen, but if you went back, for the sole purpose of changing something, wouldnt that thing you changed be for the better?

Like for example, say you built a time machine today, and went back in time to 10/9/01 (9/10/01 for you Americans) - would you not inform the police and army and do everything you could to stop the 9/11 terror attacks? Therefore making the world obvious to terrorism in general like it was pre 9/11? I know I sure as hell would.

Impossible.

You can't "travel" to the future... it hasn't happened yet. You could, theoretically, go into suspended

animation and wake up in the future... but then again, you do that every night.

As for the past, I'm of the thought that it can't be "changed". If YOU travelled to the past and changed

an event... say, killed Hitler... then as far as I would be concerned, Hitler died when you killed him.

As far as the rest of the world would be concerned, he died when you killed him. Therefore, nothing "changed"

as far as anyone is concerned. And you couldn't then travel back to your future because it no longer exists.

It has been theorized that "alternate realities" exist due to this. I live now. I know who won the last Superbowl.

If you went back and changed the outcome, I would not suddenly remember differently. My present would remain

constant. YOUR present, however, would be the one you just created. Me, in THIS present, is a completely different

person that the one you may encounter in your past (now your present).

It's a paradox no matter what you do. If you travel back in time, then your future self would have no desire to travel back in time, so you would never travel back in time to begin with. That's the way I see reverse time travel anyway...

But could time travel not shift the time traveller into a alternate timeline, rather than alter the future/present of the present time line?

My own theory ... if time travel became possible, it'd be made illegal striaghtaway, simply because some greedy

buggers would abuse it for their own personal gain, like going forward in time, and finding out next Saturday's

all the winning numbers on the National Lottery thus guaranteeing at least one big jackpot win.

One other reason why time travel would be made illegal ... going back in time, changing something about any

major historical event, which could have massive repercussions for the present time and possibly the future.

Supposing someone were to go back to 1939 Germany, and tells Hitler how to avoid being defeated?!?

Although time travel based sci-fi shows like Doctor Who are made to be completely fictional, The Doctor is

right that things that happened in history are fixed points in time, and they must always stay that way.

From a scientific standpoint, it's (theoretically) much easier to "travel" forward in time than backward. It's theoretically possible to bend space and time so that past events can be witnessed, but not altered. Travelling forward in time involves very fast space craft and extremely large amounts of gravity (eg. big stars, black holes, etc.).

Considering you said that it's possible to travel forwards and backwards, wouldn't it be logical that they could travel back to their time?
