Well... I don't believe in time itself, so I'm not exactly in a position to argue for it.

Time and space are linked hence the name space time. For example time is effected by gravity therefore clocks higher from the ground i.e. the earths gravity move slower.

Its true, the effect is very small but if you stand on top of a tall building time will be slower for you than those on the ground. Its absolutely tiny and would have little effect on how long you live but as we get further away from Earth the effect is greater hence why satalites have to be recalibrated or else they would not work.

Simiarly you could use worm holes (if they exist) to time travel. Instead of going the long way aroun you skip out the journey and arive before yourself.

Infact we are all time traverling now. Even at the speed of light it takes awhile for us to see things over great distances. Stars could have died years ago yet we still see them in the sky, There is a similar effect with the sun. What we are seeing is the sun 8 minutes ago so we are effectivly looking into the suns past.

There is also the well documented Phenomenon of Valve time as well :).

Very cool stuff.

Time is an abstract concept created by carbon based life-forms to monitor their ongoing decay. (brownie points to whoever knows that reference)

Any distortion of how much time passes on satelites and such is just a loss of energy to momentum, and fairies.

I don't think it will happen, and I don't think humans will ever figure out how to do it before we die out.
However I feel that it is possible.

I don't believe it is possible because if someone did go back in time and changed something like made it so that the Holocaust never happened then that would mean that you never went back in time to stop it so it was never stopped.

Let's see if I understood this correctly: time travel to the past is impossible due to causality, but time travel to the future is possible via special relativity. Soo...if you want to travel to the future "slower" than everybody else, move very fast. In other words, a second for you could in theory be equivalent to a century for everybody else.

Well from a logical standpoint traveling to the past is impossible, anything you do would result in a paradox, traveling to the future however might be possible, imagine a machine that uses gravitational time dilation to speed up time in the whole galaxy while you are protected from the effects of it, that would basically be time traveling to the future.

As I type this, I am travelling forward in time. As I think back to days past, I am traveling backwards in time. In that sense, time travel is very real. The ability to travel back in mind and body with the ability to manipulate events however, may not ever happen. If it does happen, than it has already in the future and is strictly regulated. If travel to the past is possible in the future, than we in the present are not aware of it because either travel into the past causes the creation of alternate time lines or, it could be impossible to manipulate anything at all (kind of like the Harry Potter time travel thing, where you see the past but are as substantial as a ghost)

Speaking of ghosts, I think they may figure in to the mystery of time travel. There are instances where we see apparitions of long dead individuals and yet, they seem completely oblivious that they are being noticed in our time. Maybe a distortion in space-time reveals them to us. It could be that a similar distortion does the same thing to us. Look around: it could be that someone from the future can see you. As to weather we can create a way to control this phenomena remains to be seen.

Not into the past, but man has already proven that time travel into the future is already possible. All we have to do is get on a spaceship and orbit one of the largest planets we know of for 50 years. Then when they got back, 100 years would have passed on earth.

I don't think that it's possible. Traveling through time and seeing my own self doesn't seem possible.

Now, it's cool to think that time can be changed. For example, someone with the power to change time can make it either go backward or forward for everyone. So, rather than one person going backward or forward in time, time changes for - and affects - everyone. It would also be cool if you could choose who remembers what time they were in before you changed it. I don't know; just something fun to think about. I don't even know if I'm really making any sense. But simply put: I don't believe that time travel is possible.
Essentially, I subscribe to this idea:
Namely, while yes, you can go back in time, you can't actually change anything relevant. So yes, Nazi Germany murders dem jews, you go back, but the only change you ever affect is some minor detail. Like calling it 'Cyclone-B' instead of Zyklo-B (Or whatever.

I also don't think FTL theory is correct. I don't imagine the universe has a 'speed limit', but rather light travels at that speed simply because of the energy that reaction gives it. So powering your space ship with antimatter will give it a faster, all-be-it more explody, way of getting around. But that's just some random thinking.

So could we travel back? The thrust of it, for me, is probably, but what people seem to forget ("Where are all the timetravelers then, dickhead?") is that we don't have a perfect system of records, so as a time traveler, I could easily jump into 2010 America, play some poker, have abit of sex and easily jump back again without anyone even batting an eyelid. Or, in more internet friendly jargon, only the trolls would appear in our history and seeing that there are thousands of trolls in our history, I would wager atleast one is a goddamn time travelling dickhead.

Also, if a time travelling dickhead is reading this response, the lottery numbers for the next three euromillions (UK lottery) please. Also the plans for the time machine. Dickhead.

If we assume that the technoligy will be invented some time soon, that is in a few thousand years, and that civilisation (including that knowladge) will not be destroyed until some thousands of years after that. Than shouldn't the "present" and "past" be abselutly crowded with time travelers? I mean humanity will probably keep on reproducing and multiplying for all that time so the people who have access to time travel will (on the whole) outnumber those that don't by quite a lot.

So unless the "future" of humanity is much shorter than it's "past" I really can't buy into the notion of timetravel.

I hope it isn't invented, think of all the problems it could cause. It would be irresponsible for any scientist to invent such a thing.

I think of it like this:
has the past ever changed? No? Then obviously time travel is either impossible or never discovered.
But if the past is changed that means it has never happened so we wouldn't know there was a change. For example if somebody went back and shot hitler before WW2 and it never happened we wouldn't know that it had happened in the first place because it never happened.

What I am saying is we wouldn't be having conversations like the following:
"Do you remember when there was a world war 2?"
"Yeah but then there wasn't"

There's also the whole "time is a human construct" thing.
No. It isn't.

For example, for any chemical reaction to go from point A to point B, it needs time.
A good idea to prove this:
Light a candle.
Leave the room.
If the candle has continued to burn after you have left the room, time isn't a human construct, its a physical law. Which it is.
