There is a really good reason that when you try to explain time travel, it makes no sense. For example the going back and time and ending your own life as a baby senario, makes no sense whatsoever.
Time is not real. Time is simply a linear perception that humans use to help the world tick over, and to get things done. Time is an invented perception of the world we live in, and has no physical basis in the real world. As far as the world is concerned, it just exsists, period. No past or future like we see it.
Our minds are rather small and it's very hard to comprehend things in any other way then in linear time. That's okay though because the universe is ment to be that way. So just don't give it too much thaught;
I dont believe its possible however some astronomers have created theories believing that black holes sink through the fabric of time.
Have you seen the special halloween episode of The Simpsons where Homer rebuilds the toaster and goes back to when dinosaurs ruled? He killed one thing and that changed everything in the present.
Even if they find a way it wouldn't be moral to everyone and to religions. People would want it for themselves anyway to give you an idea of what would happen if such a thing was created I'd give you an example, if the Germans wanted a different outcome to all wars they were in what would happen to the present?
The past, probably not, but we shall wait and see.
Traveling into the future is a different matter. I don't know if you have heard the story of the two sisters and the rocket ship: There were two sisters on earth. One of them get onto a rocket and was sent into the cosmos for a considerable time. When she returned from space, the sister in the rocket ship was much younger than the sister on earth.
I don't remember that story exactly, if I watched this video I have, I could tell you, but I don't want to watch it now. Anyways, the sister on the rocket traveled into the future, by way of space time curve, or some jazz like that.
Anyways, I found this wierd article, you might want to READ

Your describing Stephen Hawkings theory of special relativity you can find the article on www.howstuffworks.com I read the article, and I almost fell asleep it was that in depth.
If your smart and ready for new concepts read it if not dont.
If time is not real and doesnt have a physical level , then what is it that continues to make our bodies and possesions degrade over periods of "time"...I don't get it, time is real....or is it? Your opinon,is cool..but I think that time is very real to all of us.

Time must be real, time started (with a possible big bang) and will (in theory) at some point, will end.
Maybe calling it 'time' is the part that is making this sound wrong, but there is no other name for it. No direct insult to you, but you've just complicated this matter even more. Saying that time doesn't exist, when it does (you wont stay your current age forever) - humans - like everything else NEED time to exist, else we would not exist.

This guy has a point, and i do also agree that your opinion is somewhat unique, just a little baffling.
As for Black Holes, they are suppose to slow time (although this is again some sort of theory, seeing as we have never encountered one, yet, if we did, besides knowing that it's hovering about our solar system, we wouldn't actually notice any difference, unless we were maybe on another planet and time from one planet and another being different - although, it would be anyway as that other planet would have a different sun, different days and different day times (a day elsewhere may last 31 hours) - in which case, would that be classed as a day or would everyone still go by the earth time?
personally, i dont think time travel is possible, or will ever be possible.............
plus, imaging if you screwed something up in teh past.......
i think that time travle will be possible because we manged to build boats when we learnt we built trains when we learnt to so ithing when we learn to we will be able to time travle
In fact you can travel forwards. One of the astronaughts who orbitted earth currently holds the record for most time travelled, travelling backwards is more or less impossible though. If you did travel back in time, you would be a duplicate copy of yourself. Confusing, but it is possible to travel forwards at the moment. It was on horizon a bit back.
Any thing is possible these days now. Like people already said in here we can fly and that was impossible 106 years ago. Computers and Cars people thought would never happened, same thing with the light bald and tv and radio. Going into space every one thought that would never happen at all and we did, we walked on our moon. Every thing is possible. So yes I do believe we would make something to take us back in time.

No, time does not exsist. I'm not saying that things don't change, they do, but they don't change as time goes on, the just change. Its humans that perceve the change as the future, past or present. Its all in your mind.
"In the past bill made a cake"
Bill still isn't making a cake, in the past. It's just a human perception that lets you refer to things that have happened. But its not still happening. There is no past and there is no future, and there is no present. Everything just is. Your just perceving it in a way you comprehend. your human.
