Time Travel , Is it Possible ?

Why or why not ? Over the history of mankind people have always thought certain were impossible and they were wrong. Has anyone or any group actually tried to research time travel ? I can only wonder what a team of the top scientists in the world with the budget of SkunkWorks could do. Personally, I see no reason why time travel cant be possible.

But I read about the research that spurgesmastur mentions, that light can exit a fiber optic even before it's transmitted from the source.
That was facinating stuff.
On another note, it was a danish scientist (woman at that) that led the team who slowed down the speed of light to about 40 miles per hour - when it should have been 186.400 miles per second.
So the opposite is also possible - as well as it was made possible to put the brakes on light too - catch it in a specially charged atmosphere, and release it at will.
It's a facinating thing really..
Timetravel?
I don't know.
I might be more interested in that StarWars "Beam me up".. kind of stuff.
If time travel were possible, that would indicate that everything is written in stone and pre-destined to happen, especially if you want to consider travel in the future. Everything would be linear, you'd just show up at the designated point along the timeline.
OTOH, I experience time travel every single day, as do most of you. The problem is that we can only move in the future, not in the past. I close my eyes at night, and when I wake up, it is morning.
While working for Mitre, I was introduced to a concept called "timeality". Basically this is the theory that as you approach the speed of light, time slows down. There is a strong argument that if we had the technology to reach distant planets (1000's of light years away) that you couldn't ever send a person because they'd be dead in the length of time it takes to get there - even at the speed of light, it would be 1000 years to get there. But using the timelity argument, in the pilots estimation, the trip only took weeks.
According to Einstein's theories, we cannot exceed the speed of light. This is why researchers are looking at wormholes (folded space) as a way to cross great distances. That is another very interesting topic!

LMAO [:D] He must have some good meds.
This has been proven to be fact. Someone launched an atomic clock into orbit on a fast moving satellite and compared its time with an atomic clock on earth. There was a difference in the clocks that could only be attributed to relativistic effects.
On the matter of time travel: it seems obvious that you cannot travel into the past. Otherwise we would be putting up with obnoxious time tourists from the future. It may be possible to travel into the future, but current thinking is that there is not one future but an infinite number of future paths which narrow down to one as soon as the future becomes the present.
So would science fiction, and it wins the Occams razor test.

On the contrary Select-fire, I would say they are not working at all![;)][}:)]
Time travel would require travel faster than light speed. Material objects cannot travel that fast, thus cannot time travel.
I'm not smart enough to understand Einstein (hell, I ain't smart enough to understand DancesWithSheep), but if I understand it correctly, one of Einstein's theories says if you can reach or exceed the speed of light, you can travel into the future, but once you get there, you can't come back. It's one way travel.
I can sit on my @$$ and accomplish the exact same thing. Think about it, you'll realize it is true.
We're all travelling into the future. We have no choice. We only stop travelling when we keel over and die.
there will be some amazing advances in knowledge and technology in the future.
OK Scotty, beam me up.
Relativity says that time is relative to the observer. Absolute time slows down as speed increases. So if someone left earth traveling at near the speed of light for one year, when he returned he would find that thousands of years had elapsed from the earth's perspective.

How do you know we're not? Perhaps they've always been here and we just don't realize it? Check out the movie "Millienium" with Cheryl Ladd.
It was all downhill for us Celts once the damn Romans invaded.
800 years ago the concept of live television would have been deemed impossible by most. how can someone in London see something going on in New York ?

Technically it isn't "live"; there is still a small delay between what you are seeing and what happens.
That delay is ALL the difference, actually.
There are relativistic ways to change the flow of time, but in terms of the HG Wells novel kind of time machine that can bring you forward or back at will, Einstein says such a thing is not possible.
And whether or not Einstein is right, it certainly can't be done with today's technology.
As a side thing, check out this vid of the Einstein robot. . .freaky!
Captain Kirk and crew already did it. More than once. All you have to do is slingshot around a sun, at maximum warp, or something like that. It must be true, I saw it on TV.
Because Einstein said so? Coming from a man who traveled BACK in time, from the future, to fill our heads with a bunch of scientific mumbo-jumbo. Do you really expect him to ADMIT to the fact that time travel exists?
"Captain! Here there be whales!"
You know (or should) that it also works when the need arises to go back in time, so that the Vulcans could discover the planet earth, when earth tested the first warp-powered starship. Couldn't let the Borg mess that up, or we would never become a member of the United Federation of Planets.
They also taught us, that it is possible to travel back in time, if the warp engines implode. You got an inside glimpse of the crew that time.
It was an accident, when they did a slingshot around a black hole, and ended up almost screwing up the 20th century. Good thing they got Captain John Christopher (and the rest) back to their rightful places in time, before there was a real temporal catastrophe.
If they had taken out Hitler (when they used the Guardian to go back in time) where would we be now? Of course if they hadn't set thing right, the "Time Cop" would have been ALL OVER them like stink on s**t.
The Time Machine
(Gary Burr)
He circled and stared
Nervous and scared
He knew both the thrill and the cost
But he didn't think twice
This amazing device
Was his last chance to see what he'd lost
If time is really a river
And upstream's where he needed to be
He set his sights on the past
Finished his glass
And went back in history
To the casual eye it's a bar stool
But it's really much more than it seems
A few drinks and then
She'll be with him again
As he sits on the time machine
Like all pioneers
He swallowed his fears
And watched the whole room fade to black
He's dying to go
But he's no fool, he knows
How hard it will be to come back
But tonight he's tired of the lonely
And tomorrow will not be the cure
So he'll just slip away
Find yesterday
And spend one more night with her
Now as far as these customers can tell
He's just one more fool who talks to himself
But every man in this place would line up
If they knew what that seat really was (but)
To the casual eye it's a bar stool
But it's really much more than it seems
A few drinks and then
She'll be with him again
As he sits on the time machine
Just a few drinks and then
She'll be with him again
As he sits on the time machine

Straight from NASA....gravity slows down time. Absence of gravity speeds up the time.
JUST in time.
I think Truman Capote was a time traveler from the future.
Imagine yourself sat inside your car in your garage, and on the wall facing you is a clock. Now imagine that no matter what happens you can always see that clock and keep in mind what you are actually seeing is light coming from the clock to your eyes.
Put the car in reverse and start accelerating. At first nothing seems to change, remember you can still see the clock, but as your speed increases the light from the clock has problems keeping up with you and the clock appears to slow down. In your garage the clock hasn't changed and in your car everything appears normal, this is the relative part of Einsteins theory. When you hit the speed of light you are travelling away from the clock at 186K miles per second and the light from the clock is travelling towards you at 186K per second, so from your point of reference the clock in the garage stands still. Now go even faster and the clock starts going backwards because your overtaking it's earlier light image, and your travelling backwards in time.
Untill they manage to travel faster than light, which Mr. Einstein say's would require infinate energy and is therefore improbable, it's all theory.
Hope that was as clear as mud for you.
