I have seen the movies and read online about it... but I don't believe in it. I feel like humans will and have tried to create Time Travel Portals but it is just simply impossible. I think sometimes it would be cool but there is somethings in my life I wouldn't want to relive.

I myself believe in Time Travel. I am going to say it flat out here, you can't put religion in something like this, because they are two very different things.
There are so many scientific theory's of how the universe works, like the multiple worlds theory (Not sure if this is the actual name or not) which states that every action that has ever happen has had 2 or more reactions, and as such makes other universes, in which it played out differently each time. Now, let's say we time travel, we could wind up in any of those universes, and the possibility of it landing on our universe and proving time travel exist is incredibly small, it is almost impossible (Also known as improbable).
Time is in our heads, and as such, the older a person gets the faster time moves for them. In a sense, they are time traveling, as they are "going" through time faster than other people.
Now, let's say time is a "Cause to effect" thing, meaning that if we do something in the past, the future will be changed, no matter how small. There could be an entire timeline that happen extremely different, and there right now the world's dominate species is, let's say crickets. A time traveler could have changed one tiny thing, like moving a rock or something, and now Humans are the dominate species. We can not know of that, but it could have very well happened, just in a different timeline.
Now, let's say time is not a "Cause to effect" thing, meaning that a time traveler could go when you were born and killed you, but would not effect the future and/or present. With that, there could be time travelers everywhere, but we could not know.

There is so many things about time travel, that you cannot just say it is "impossible" because reasons like "Than why aren't we seeing time travelers everywhere?" or "Why hasn't history changed?" or even "A lot of people say it is not true, and I say it's impossible". It is not impossible, just improbable. Even if we do find a way to time travel, making it possible would be really hard, as we would need to find an energy source that has infinite power, which now that is impossible, and something that could break atom/molecules and put them back how they were without any changes.

maguc : I agreed with your last paragraph. Things like "time travel isn't possible because then we'd see time travelers" or "history would be different" entirely fail to encompass the problem. How would we know?

Did you ever read the Key to Rondo by Emily Rodda? Two children end up in a magic world contained within a music box, and the world freezes if the music is not playing. The boy, Leo, says, "I'm glad our world isn't like that!" and one of the music box denizens replies, "But if it was, how would you know?" 

If history was changed, we would have no awareness of it. If there were time travelers everywhere, we wouldn't recognize them as such.

Myself, I believe that it's possible to time travel, but not possible for us to achieve it. We would have to devote 100s of years to construct a machine to do so, and we still probably couldn't rupture time.

maguc : Says the guy with the Doctor Who post layout... Just joking, man.

TheFadedWarrior : That's my opinion too. Time travel IS possible. It's just not HUMANLY possible.

I think it would take infinite amounts of energy to go back in time or maybe shrinking machines such as those in Crichton's novel "Timeline". So as humans we won't physically know for a long time. 

However, theoretically, I believe time exists as a dimension (duration). That's because science has already shown that time moves at different rates depending on where you are. If you're on earth a year will be shorter than if you're in space.

I also believe time is like a tree, with infinite branches. If one were to go back in time and alter it in any way, then (s)he would go along a different branch than the one previously traveled.

EideticMemory : Well, "clock" time is different from "real" time. Clock time is relative; it's a different time no matter where you are, and "years" and "days" are based on a planet's rotation around the sun. But as clock time differs depending on where you are, real time always stays the same, unchanging. Real time is what the dimension of time really is, whether it's the fourth dimension or some other one.

Your theory about a tree is quite interesting; I haven't heard it before, but it's quite similar to the "infinite universes" theory- every choice has a million possible outcomes, and a million universes showing what would occur if that particular outcome had been chosen. Similarly, if you change an outcome, you change these universes as well and add even more to the never-ending web- though it is supposed to be an infinite web, so your change is already accounted for... It is a perplexing theory.

A user of this : I think I told you this earlier, but you're right. For all we know, the yesterday I remember isn't the yesterday that really happened. If someone came along and changed everything, time would be rewritten, and I wouldn't have a clue. This is a theory often in practice in Doctor Who, as I'm sure you know. If you've read "A Sound of Thunder" by Ray Bradbury, that is one of his two main theories brought up (the other is the Butterfly Effect). Only the time travelers knew what the previous world was like, and that was because they were the ones who had "created" it.

EDIT: This 'embed' thing keeps showing up in my post. Does anyone know how to get rid of it?

No, I do not believe in time travel. It is hard to explain why I do not believe in it, but to put it bluntly, it is because the idea seems a tad far-fetched. Kind of hard to believe itself, also, difficult to believe how it could be possible. Same thing as not believing in Santa XD!

I don't believe or disbelieve time travel because it's not a thing to have faith in for me. If it is conclusively proven, or has mountains of evidence all pointing towards it, then I will believe it can happen. If it is conclusively disproven, I will not believe that it can happen. The same goes for all my beliefs. If there is an overwhelming amount of evidence that all points towards it, or I have experienced it myself, I will believe it. If not, I won't.

Travelling through the dimension and fabric of space and time is probably not possible-and definitely not natural in any way. How can the Past...and the present...co exist? We do not know anything of the future now, so if we travelled forwards, it would cause a paradox if the present day had a time machine and the other times dis not.

If it did exist, it would cause a lot of problems in history. So probably no.

Time travel is very much possible. According to Albert Einstein, if you are going to or close to the speed of light (which is impossible as fare as we know, but may not be, who knows). When going the speed of light for you time will go slower but everywhere else will be going normal speed. Say you travel at the speed of light for what feels like 5 years for you, it would really be 5000 years back on Earth.

So yes time travel is possible but not for us to utilize now, but one day it could be a possibility.

Well, as a devout Whovian I'd like to think that at some point in time (haha get it?), time travel will be possible.

But I'm constantly reminded by just how unfeasible the idea is. I mean, if there was actually a way to transport an organism to the past or future, there's no way that It'd every be available for human use considering how easy it would be to drastically alter the future.

If I ever do go back in time though, at least I know to watch out for butterflies.

NVTaks : Ha ha! But if you really want to avoid changing the future, you'd have to hold your breath the whole time. That air you're breathing- it would've gone into another organism that would have processed things differently. The Butterfly Effect- ratcheted up a notch!

I dont believe in Time travel.This for me is fiction.Just an illusion

We are in the era of technology and science. Why not?

Dragonlord Stephi : yes but every time i think about it i think how this and that would happen and then i get really confused...

yep, It's completely possible, if people believe a deity could create the universe, why not time travel?
