I don't know whether it is possible, and I don't much care. It shouldn't be done. What about paradoxes? The possibility of not just people being murdered, but never existing in the first place? Even travel to the future is unethical. No man should know what the future holds, and neither should they have the right to attempt to alter it as they see fit.
Time travel to the future is possible, as time is apparently affected by gravity. So if you flew around a black hole for 4 years, the rest of the universe would have moved on 12 years. This would of course mean you need not only a space ship but one that could resist the gravity of a black hole. That aside, it is possible.
Time travel into the past isn't. Theres a theory that if you build a time machine, it can only travel back to the point where it was turned on, but I doubt that will happen. Theres also the whole paradox problem, which Hawking believes the universe would self correct simply by stopping people from going into the past. As in, someone opens a wormhole to the past but it instantly closes again due to being unstable.

I believe time travel is possible, only by the means of exchanging minds with inhabitants of future or past places. The best example in a story where creatures do that is from H. P. Loveecraft's story "The Shadow Out of Time". The way it's described seems to make perfect sense of how it is possible.
I believe time travel is possible because of a gut feeling about science, if that makes any sense. We believed that the speed of sound was as fast as anythign could go, you couldn't break it, and when we did it, it created a shock wave. I believe that our current beleif that you cannot travel faster than light is equally as false as the belief that we couldn't travel faster than sound, and for no reason whatsoever other than a gut feeling, i believe that breaking this "light barriar" will result in a shockwave which could be manipulated to travel through time.
I take my opinion based from cracked.com
If ever the time travel backward will ever become possible it would give too much hassle to just try and do it
1) Calculating the exact position of the Earth and the place on it you want, it would require alot of calculation
2) You will be trapped in that time
3) It would become very hard for you to identify yourself, get money or you will get the attention of all the people around (just try and walk in a toxedo back then in 1920)
4) Traveling in time would not necessary mean that "YOU" will be there, only maybe a exact copy of yourself, like are souls transferable? Meaning that you would just "kill" your very own self but "creating" an exact clone in the past?
I think with all the question around it and the possibility of impossibility I come to conclusion I will never exist

I read somewhere that time travel was possible, but it would destroy the universe. Sounds a little extreme.
I think it's possible, but the consequences could probably be pretty bad, even if you only changed something small.

In theory time travel is certainly possible and would almost definetly require the use of a black hole or at least an immense gravitational force. However in practise its impossible we dont have the technology to attempt time travel, for one it'll will probably have something to do with reaching the speed of light or faster which is impossible because you can only travel at the speed of light if you have absolutly no mass. It's why they can only send particles at 99.9% the speed of light at the hadron collider.
also as a load of people have mentioned going forwards is alot easier then going backwards. e.g. to go forwards all you need to do is get close enough to a black hole that time is distorted, so 1 second to you is a day on earth.
where as going backwards...idk maybe if you went into a black hole faster than the speed of light so that you could reach its pinnacle center but coninue onto its counterpart side. taht way 1 of 3 things will happen. 1, youll die. 2, youll have travel a vast distance in space in a few short minutes (wormhole basically) 3, time travel, a different place and time.
what we do know is its all theorectical and is not going to be possible in our lifetime

Fursnake said:You don't have to accept that everything is pre-determined to believe in travelling to the future, for example, I just travelled one second into the future. If that doesn't qualify as time travel than how would you define it? Your point disproves a type of time travel where you would be instantly skipping several years. But that would take an infinite amount of energy so is impossible anyway. In a practical sense however you could, by travelling extremely fast, pass through time faster than everyone else. Is that not good enough for you?Rockchimp69 said:
And about what you said about everything being pre-determined, i'm sorry but that is simple not true. Everything happens for a reason, and if you knew all the reasons for something, you could accurately predict the future, does that not count as the future being "pre-determined"? I agree that different points in time probably aren't "stored" somewhere but I do believe that because of Causality the future is pre-determined. But that doesn't mean we can't make decisions about things, which I think most people don't understand. We are still mostly in charge of our own lives, the future being "pre-determined" just means that we can PREDICT what's going to happen.
Anyway sorry about this long reply I just got a bit carried away there
Sounds ridiculous, what the person probably meant was that it is possible in some limited form, but the energy released would devastate the universe as we know it. You can't "destroy" the universe because the universe is a concept of everythingWenseph said:
