Well, it depends on what you mean by time travel.
Time is relative after all. So it is possible to 'travel into the future' relative to a different location.
And it's very easy to look into the past; light does not travel infinitely fast after all.

The possibility to "go forwards in time" is not something i'm going to dispute (approaching the speed of light and all that), but i know that it is a question about relativity (did a short course in high school) and therefore it is disputable whether it's "real" time travel (it's definitely not like in the movies).
I believe "going back in time" is physically impossible, unless you regress reality backwards in time (like rewinding a tape). This would create an endless cycle where you regress time, stop, resume doing exactly what you were doing at the time (memory would be regressed as well, obviously) untill you reached the point where you regressed time. This would continue in an endless cycle, and no-one would ever know (scary thought!).
the closest thing i think we can come to it is what some ppl have mentioned here on the thread: Alternate realities. Realities that developed exactly like ours, except they are older or younger than ours. Skipping from our reality to another one that is 100 years older than ours would allow us to see the world 100 years older.
This would probably solve the whole: "If you meet yourself in the past/future the paradox would destroy the universe" problem, it would be someone born,raised, and having lived a live exactly like yours, but they would still be a separate organism. Weird (someone who looks and thinks exactly like you), but it wouldn't be a paradox.

Time travel is already possible. We are travelling through time right now.
Seriously though, Hawkwing (rather regretfully) postulated than time travel to the past is improbable due to paradox.
It is however completely possible to travel to the future. Just orbit a body of incredible gravity (let's say, a black hole), due that for 10 years, come back and BLAM! It's the future. Time on Earth will have passed faster relatively to you.

(Relating to traveling backwards) I really doubt it. Aside from reasons already stated by people, I don't think time is a force or whatever that can be interacted with. It seems to be a concept related to the movement of electrons.
(Relating to traveling forwards) Just go to sleep. Or stand there.

Since people don't really pay attention to what happens around them anyway, it would at least be possible to get away with a few empty decades, a bunch of misplaced wars, and anachronistic inventions - so why not? Wouldn't create a paradox - clearly the universe doesn't care about things like order and logic, and neither do people.
So given that it would be possible - no doubt it could take place around us all the time, and nothing would really be upset because of it. Basically, events would just fit in between each other like before.
I'm sure it's actually impossible physically, though. It defies logic to revisit time that has already passed, so I don't think it's possible to imagine a scientific method that would take us anywhere. Would be like jumping the gun and developing a method for something first, since the initial theory doesn't make sense.

No, I think we put too much belief in math and theory (coming from someone graduating with a BS in Math). These ideas were constructed by man, and it's easy to overlook their limitations. All math and theory is based on axioms and observations, and once we realize the error in these, the whole tower of knowledge becomes worthless. With that said, I believe that there are restrictions on time that human beings fail to observe. Do I have proof of this? No, it's just a gut feeling having lived 21 years in my natural environment. People wouldn't have thought planes or light would exist either. Still, time travel seems like a much more drastic concept than the other two.
I found an interesting theory I've never heard of before concerning anti-matter on "Irregular Webcomic" a few days back... [link] [http://www.irregularwebcomic.net/2874.html] Something for those with a basic understanding of anti-particles to dwell on.
Controlled time travel is possible, at least in the "forward" direction. It's a given from Lorentz transformation equations that you with a suitable device you can move forward in time at controllable speeds. Backwards, though, is the big issue. This sort of situation would require a negative Lorentz Factor, something that (as far as I can tell, it's been a year or two since I learned this, so I might be a bit rusty) isn't possible (in conventional mathematics, anyway, I'm sure if you start putting in stuff like divisions by 0 or imaginary numbers weirdness may occur, but that's all theoretical, you can't travel at "i" meters a second!).
As for time paradoxes... I don't believe they exist. As far as I can tell, almost all of them require for people to do monumentally stupid things, like kill their own parents. Which only causes a paradox in the human sense. At the end of it all, you're an assembly of particles, which isn't by itself paradoxical. There are more than enough "John Does" or "Jane Does" out there, how do we really know this hasn't been done before?

I'd say I'd have to agree with Kushan101 here. I believe time isn't a thing, but merely math. It's the measurment of events. In three seperate examples I'll try to explain my opinion.Kushan101 said:
1. Say you do make a time machine, and it takes you 30 secs to travel back in time to whenever; then you have added 30 secs to your relative time. Therefore you did not go back in time, but forward by 30 seconds. The events that occured may be the same as they were in the "time" you visited, but time did not go backwards.
2. You make a time machine that travels instantly. Similar to the first example, you did not subract any time. So time was not traveled.
3. You make a time machine that subracts time. You travel back 30 secs in time, which would mean you occupy a place in time before you subracted the 30 secs; so you did not subtract any time yet. Think of it as math where no matter what number you subract the answer always equals 0.
I do realize all of those examples are regarding traveling backwards, not forwards. If traveling forward in time is possible it would logically mean that every possible event that will ever happen in time can be predicted with 100% accuracy. We may not be capable of it, but it would be fact. Things will evolve on an absolute linear path, people will make a specific choice, and the world will end no matter what you do. We're all just puppets in some divine play titled destiny. I may be spiritual, but I refuse to submit to being a puppet. That's just my opinion though. Is moving through time at a faster velocity possible? I'd say closer to plausible, rather than possible. Seeing as you can't subtract time though, you would be stuck in what ever instance you traveled to. Quite the nasty paradox.
I recall watching a documentary saying it may be possible but at extreme temperatures and at extreme speeds. So I believe it is possible in a way, but for humans, not for a long time.
Just because you can't prove something doesn't make it true. I can say that the entire world is controlled by a bunny rabbit smoking a pipe, which you technically can't disprove, but that doesn't mean it's true.TheYellowCellPhone said:
Anyway, I don't think that it is possible. First of all, you would need a way to control WHERE you time traveled. Think about how fast the earth is rotating and moving around the sun. If you shifted in time for just one second, you would find yourself in outer space. The ability to both travel backwards and control exactly where you landed seems insanely hard.
Also, if it is possible, where are all of the time travelers?
I'd like to think it's possible, but I have a feeling it most likely wouldn't be.
I think forwards time travel would be possible, but I think backwards time travel is impossible.

It's an educated guess, but I don't think that travelling back in time is possible, simply because matter can't be created. Let me explain how I see this...Rockchimp69 said:As I explained in my last post, I understand that traveling forward at varying rates is possible, my question is whether direction can be changed.RUINER ACTUAL said:There is a definite answer- it is possible.Rockchimp69 said:As the subject says, post if you believe that time travel is/could be possible or not, and why.
A few rules for this thread:
Firstly your reason has to be either scientific, logical or a gut feeling. It can't be something retarded like "time travel is just in movies so it can't be real!!!"
And secondly, no insulting other people's views as there is no definate answer for now.
Personally I think that as time has been observed to warp or "dialate" in situations such as fast moving atomic clocks in orbit showing different times to those on earth, it may also be able to be affected in other ways, e.g. Bending it or folding it to send a body to a different time.
But that's just mewhat are you views?
The reason those atomic clocks are different in space than on Earth is gravity. If a human were to orbit a black hole for 10 years, when they came back, they would be 150 years in the future. The Cosmonaut that was on MIR for 18 months is 0.048 seconds in the future. Gravity warps time. Traveling backwards is not possible in our 11 dimension universe, only forwards.
Edit: Also are you sure its not the speed the object is travelling at? Or maybe a mixture of the two?
At any given moment in the universe, the amount of energy and matter is constant. Nothing is created, only transformed. Travelling "in the future" by increasing your speed still is possible, since you don't exactly disappear from a moment to reappear in another: you're always there at any given moment.
Travelling back in time, however, would mean subtracting yourself, with all your matter and energy, from a given moment, and adding all that energy and matter to another moment in the universe. Travelling back in time would basically create variations in the amount of energy in the universe, which is not possible according to the laws of thermodynamics.
But it's an educated guess. What do I know, I'm just a programmer!
I really hope not, imagine the stupidity if the United States (or other countries, but US seems more plausible) got their hands on it. There'd be rednecks going back to the civil war in attempts to assassinate Lincoln before the Emancipation Proclamation, or our government going back and detaining Assange before Wikileaks. What I'm saying is that whoever holds it is going to try and change history causing our world to be one big clusterfuck
i think no. something that happened....well,happened,no going back,and for the future, it didnt even happen yet,everything in the future is influenced by the present.
