Now speaking from a sheer scientific point of view, do you think Time Travel is possible. I believe it is in someways, but only forwards. There have been instances were two clocks were sychronized, and one was flown on a supersonic jet. Upon its return, it was discovered that the one on the Jet was a few hundreths of a second behind the one on Earth. I believe that if we ever find a way to approach the speed of light, that we can travel to the Future. Now, I don't believe that you can go backwards. To thoretically do this, you would have to move slower than Zero. Plus there would be many paradoxs like Einsteins famous Grandfather one.

Heh. Traveling forward would be fun. The moment you leave, you could say

"When I get to the future, I want there to be a huge celebration on the behalf of the thresholds of mankind."

Then, you could get in the time machine or whatever, and when you got to the future, there'd be a celebration. Because in their time, the moment you leave would be in history books, so they'd be expecting you when you when you arrived. That would be fun.

However, if it ever were possible to go back in time, I think it's horrible idea. Think of how many things you could affect and change. Watch the movie Frequency to get an idea what I'm talking. It's not the same exactly, but he's changing stuff in the past.

No way it's not possible to travel back into time all those movies that haved come and went such as back to the future,the time machine and so on I don't belive you can make a machine and go back in time like that, it's totally impossible. Maybe in the future millions or thousands of years from now a intellegent person will find a way but it will be impossible but right now no way

As you get closer to the speed of light, time gets faster. Soooo... if you go fast enough, time passes more quickly for you than it does for other people. Hence a few minutes passes for you whilst on Earth it's a few weeks. It's not time travel in the strictest sense, just bending the rules a little, but there's little practical difference I guess.

Time travel may be possible, but right now it's just another sci-fi concept. If time travel were possible, you could only go forward in the space time continuim. As of right now, it's also impossible to go slower than zero, the proposed theory of going backwards.
Even if we could freely pass the time restraint, there would have to some rules. As in many of the movies, one little action could effect millions upon millions of things. Then there's the possibility of evil people changing the past and stuff. Generally it wouldn't be a good idea to go backward in time or in the future.
What's weird is that you can alter the future right now. If you think about it, you have more than one decision every time you want to do something. If you choose the wrong thing, you may regret it later. However, if you choose the right thing, you'll be happy later.

With that said, here is the real question.

Would it be a good idea to travel into or back into time? 8)

Not quite.

Time "flows" slower as your speed approaches lightspeed. But otherwise yes you would experience less time than a stationary person.

Btw this is not exactly debate room material.

I think time travel would be impossible. Why? Let's say you go to the past. As soon as you got their, unlimited versions of you would pop up, because in time you would keep on going back in time. This may not make any sense at first, but somepeople may understand what I'm trying to say. <img border="0" alt="[Freak]" title="" src="graemlins/freak.gif" />

^^ The moments it took you to get there, every moment would produce a duplicate of you?

If the Time travel thing was possible, it wouldn't work out too well.
Your standing around your friends and one spills coke on you, and you went foward in time a few seconds, you would be wet before the coke touched you, but in their eyes it hasn't touched you yet. It's hard to explain with verbal communication.

Time Travel would be neat,but it won't be for years until the invent something for it.Right now,we don't have the technology or brain power.If scientists made it,they would experiment with time,probably.Like, bring the Dodo birds back to life,learn hi dinasaurs became extinct,maybe go to the future and bring back technology.

EDIT: Shorten the sig or be punished.

I think that backwards travel is impossible, Period. How can you do it? You can't move slower than zero and let time "pass you bye", because moving at a speed slower than zero is impossible. Right now that is theoretically how many physicists think that it would be done. Plus as i said early, there are too many paradoxes.

Yavarice: This is Debate Room material, it is a scientific debate, not a theological one. It is just a change of tempo.

plus, if you travel at light speed, the theory says you would have infinite mass. then you'd be a big-*** fatso(lol)(what i tried to say is that lightspeed is impossible ) well... my point is that it's not technically time travel, but "living" faster.

(heh at last a non religious topic, plz read my closed topic to understand my point. i dunno why it got closed)

There is nothing to argue. Or if there is, rule number 4 prevents any of us from doing anything about it.

And movies are NOT a good source for information.

I believe you can travel in time, but backwards would be way harder than forwards. If it is possible, you could not affect anything to change the future since it already happened. It's like its destined to happen. You'll go back, but since it already happened, it will not affect it in any way. In fact, your being there was predetermined by the space-time continuom. The past is the past and will always be that way whether you go back and try and change it or not. I doubt you understand, but that's the way it is.

There is plenty to argue, you just have to know a little bit about science. Personally, I have read up on the subject, and while I may not be an expert, I have scientific grounds to root my claims in. Im sure others do to. I see your point though, basing your claims on a movie is not good. So how about one from a Harvard physicist:

His Theory is that there would be a magnetic force that would pull you apart if you attempted to go backwards or something to that effect. He believes that nature has a way of preventing us to go backwards in time. This is based on research that he had done concerning Magnetivity and speed.

Although we have no idea how it could be accomplished, I do think that backwards time travel could be possible. Very few situations could ever cause a paradox. The only events that could be altered to cause a paradox are those of which you already knew the outcome. Paradoxes come from using your knowledge of the outcome of events, and then changing the events so that the outcome you drew the conclusion from never happened, thus leaving no reason that the event would have been interfered with in the first place. If you didn't know the outcome of the event, your interference with an event would not be able to remove the reasons for you interfering. In effect, there would be no paradox. When you think about the vast number of events in history along with the limited number that each person knows of, it is very likely that almost any trip to the past would fail to cause a paradox.

I know of no way to travel back in time, but I am still yet to see any proof that it absolutely cannot be done, either. I just don't think that we understand time well enough to even see why time travel is or is not possible. It is generally accepted that time does exist as a linear quantity, and that objects can move forwards in time. Just because we haven't see something going the other direction doesn't mean it can't.

By the way, I do agree that most of the ideas proposed above do not qualify as time travel. In those examples, a person would still exist in the same timeline as everyone else at the same time. The only difference is that the person allegedly moving forward in time is effectively in stasis, and is thus oblivious to the time that does pass. However, the effect is very similar to moving forward in time (and Massy even pointed this out when he brought it up).

I'm certain that if it is possible to actually move through time, it would have nothing to do with approaching the speed of light. After all, you don't have to reach an extremely high speed in two dimensions in order to move in all three dimensions, why should it be any different when moving in the fourth dimension, time?

the 4th dimension is LINEAR time, which is what we live in. We only move fopward in time.

The fifth dimension would be time, squared, and basically this is how you travel sideways to different dimensions.

the 6th dimension would be hypertime, or 3-d time. you can move backward and foward in time in any dimension.

I know where you live....and you can't do anything
i believe that, in the dimenstion that we live in right now, it is only possible to travel forward in time. This is how (theoritically speaking)
you get in a spaceship and go really fast, away from the earth. u wander around for 4 years(with the clock u have brought)and u go back to earth. even thought ur trip only took 4 years according to your clock, on earth, about 30 years would have gone by. So basically, the faster you go, the slower the time flow is...

I don't think this helps Kirbitsu any, but Electromagnetism is the source of gravity. Or at least that's what wise ol' Discovery Channel told me.

Hey, it was a nice change of pace from the old "animals doing it" documentaries...

DK Dude's Resarch on Time Traveling to the Past

Okay, we all know what worm holes are correct? Its a hole in space that connects two non adjacent locations in space. Now in atoms there are worm holes. They open and close in a fraction of a second and it has to do with electron clouds and how electrons "teleport" around the atom and really really complicated stuff you can find <a href="http://www.dromo.com/fusionanomaly/timetwister.html" target="_blank">here</a>.

Anyhoo, say if you were to keep both ends of the wormhole open and stabalize it to make it "portable" [it has to do with anti-matter and exotic matter and all this weird matter stuff, but theoretically possible]. So one end of the worm hole stays in the lab while a scientist or whoever takes the other end in some sort of "wormhole preserver chamber" [work with me here] and does the whole "fly-around-the-world-near-the-speed-of-light" [uh, see Ephemeral Kirbitsu's first post <img border="0" title="" alt="[Wink]" src="wink.gif" /> ] so the end at the lab is in the future and the end that was flown around the world is still in the "present".

So the scientist in the lab who is now much much older can go though his end and end up back in time [and also the past scientist can go though his end and go to the future]! Let's pretend that a president was asassinated[sp?] which started a war in the time span between the wormhole's openings. A person from the future could go to the past, stop the asassin and the president will live and no war would have ever happend in the future... theoretically... but of course there is the whole paradox: if there was no assanation, then the furture person would have never needed to send a guy in the past to stop the asassin, but then there would be an asassination <img border="0" alt="[Freak]" title="" src="graemlins/freak.gif" /> [see Gir's ramblings in the Invader Zim episode Bad Bad Rubber Piggy, downloadble on KaZaA <img border="0" title="" alt="[Wink]" src="wink.gif" /> ]

well that's my tid bit on Time Travel to the Past... it's theoretically possible, just don't mess with anything once you get there!

Yes it could be possible to travel time with the speed of light but I still dout it it's impossible unless a smart person a few thousands or millions of years from which we currently are would built a machine or something to travel into time but for right now it's notting but fiction not real made up we can only dream of going to the past or future for now.

well, stephen hawkings says time travel is impossible, for various arguments. so did einstein. i don't say they hold the ultimate truths (i wouldn't dare), but at least they have respectable theories.

heeeeeeeeeeh. yes they said it. plz don't make me search. anyway the main problem isn't building the machine itself, we don't even have a concept on how to execute the travel. (mere theories)

Time travel is scientifically and logically impossible. Think about it... what is time, really? It is merely a system that man has created to order priorities. There is no universal clock that says, "This is the correct time!" Plus, take into consideration many other things like Daylight-Savings-Time, international date lines, and time zones. Technically if you flew a jet the same dirction as the world turns, you will be able to rreach tomorrow before everyone else(international date line), but that does not account for the set amount of time it took you to fly that way.

Oops, I've gone cross-eyed again! <img border="0" alt="[Freak]" title="" src="graemlins/freak.gif" />

To all you people who say that time travel is impossible, "Eat my shorts!" Currently, a Swedish group of scientists are conducting time travel studies with light. They are looping a continuous stream of light around a neutron forcing it to spin at an accelerated rate bending time/space until it moves through time (they hope). In a few decades we may be able to do this to larger matter.

In other words, the studies are in progress, we just have to wait for the results...

What makes you guys think that a bunch of metal could travel back and forth in time... or light for that matter. Both these things are 3-demonsial. And 3d objects/humans percieve time in present. What makes you think a machine could go back in time or go into time further than it's present state? It's just insane talk, it won't/can't happen.

Someone said that you couldn't go back in time. If this was true I wouldn't want to go forward either. Think about it going forward with no way to return. I wouldn't want to leave behind my family and friends to go 100 years or more into the future and everyone you knew would be dead. I would maybe go 1 or 2 years ahead but no more than that.

It seems that many people have a genuine interest in this topic. <a href="http://www.time-travel.com/physics.htm" target="_blank">Here</a> is some information that I found about the actual science of Time Travel. Im going to read through it and see what I can find.

The author realised that the Great Pyramids were a time travel device during a vision he was having. I feel that this is all that need be said about that paticular website, although it was quite amusing for about five minutes.

Oh, wait, I've found some more obvious, verifiable truths. Go visit if you think I'm at all quoting out of context, or misrepresenting their views:

"I was introduced to such technology by a friend and personal guide of mine from the planet Chiron."

"I believe UFOs are man-made time machines, driven by human beings which have evolved into what we call aliens. They come from our distant future, and they use these vehicles to travel to their past."

Please, <a href="http://www.clarifyingchristianity.com" target="_blank">this</a> is the only site that's been posted here before now that's that stupid...

There is no paradox as is:

"if there was no assanation, then the furture person would have never needed to send a guy in the past to stop the asassin, but then there would be an asassination"

You see, when you go back in time, you are not affecting your own timeline, you are creating another dimension. Lets say there is only one dimension, dim A.

In Dim A, you go bakc in time to save a president from being assassinated. You are now in Dim B. In Dim B, you can stop the president from being assassinated, but the president will still be dead in Dim A. You will be missing from Dim A and never be able to return, because you can't hop between dimensions, only create new ones. Also, If two people time travel from the same dimension to the same point in time, they will not end up in the same dimension, they will have created 2 different dimensions.

Time travel is very stupid, even if it was is possible... in the sense of scientific study or alterting the past. Plus you wouldnt be able to tell if you can time travel, because you can't return to the original dimension, so for all you know, you could just be vaporizing people, not sending them to the past.

bah blah blah

Time travel, with the current knowlege that humans possess, seems possible. However, there are probably all sorts of unforseen complications that make it a practical impossibility. These people that think it's totally impossible ("why could a machhine or light travel in time? it doesnt make any sense") obviousl have no knowlege on the subject. And what the HECK with with that fool Smashbrother999? He's just a confused little boy who's wandered into the wrong topic.

As fas as what X was saying, that's just a bunch of nonsense. "Time travel" is moving through the 4th dimention, but you're talking about travelling through the 5th dimention. There's no reason why you'd automatically go through the 5th just because you went through the 4th.

Akkk! What's with this 'time' dealing with the +4 dimention?! I belive time is a dimention, but not to be added onto the spacial dimentons. I belive that the "4th" and is also space [along with all other +4th dimentions]. For example in 0D you have one point, in 1D a line, in 2D a squre, in 3D a cube, and in 4D the 'hyper-cube':

<a href="http://www.heimbuch.de/Privat/hypercube.html" target="_blank"> <img src="http://images.google.com/images?q=tbn:bl_w6FqSkyUC:www.heimbuch.de/Privat/Grafics/HYPERCUB.GIF" alt="" /></a>

trippy no?! go <a href="http://alem3d.obidos.org/en/intro4d/" target="_blank">here</a> for more fun info on the hyper-cube!! Enough about that. Here is another traveling to the past possiblity:

okay let's pretend people will be able to go faster than the speed of light someday [remember to pretend]! Anyhoo, say you are wearing shooes that enable you to go faster than the speed of light without becoming pure energy [e=mc^2, blah, blah, blah], and you run from once end of a soccer feild to the other. If you stop and turn around you'll see yourself running to meet you! But this won't be physical, it will be optical. You ran so fast that you "passed" the light bouncing off your body so when you stoped and turned around you saw the prjection/reflection of the light boucning offa your body. Sorta almost ike when you look at the stars at night you are seeing the stars in the past, or the sunlight we recive is "eight minuets old".

So if people were able to travel faster than the speed of light you could "observe the past" [but there would be no sound, cuz it travels slower]. Until we can come across the e=mc^2 problem this is just a dream.

ps: I hope all my physics was correct &gt;_&lt;!!

I beleive travelling forward in time is possible, and near discovery. I read somewhere that scientists where able to send a molecule or atom or something across a glass tube before it even left the other end. Don't ask me how, but I read it in a newspaper or something.
Travelling back in time is another matter. I don't think we can fully comprehend what it would be like and what concequences would follow. Also, someone on the first page said something about bringing technology from the future to the present. This is impossible, as it would create a paradox.
But if we did find a way to travel back and into time, I don't think that anyone should be allowed to mess with time. No one has the right to stop something that has already happened, or see something that will happen, and try to prevent it. For instance, if someone prevented the Holocaust by killing Hitler before it happened, the people who descended from the survivors would probably live somewhere else, because their ancestors wouldn't have immigrated. Also, the people who were killed, their descendants would now live.

Time travel is just one big confusing thing :confused: :confused: :confused:

Ok, if you do go back into time, will there be two yous? There can't. That goes against the law of conservation of matter that states matter is never created or destroyed. When you do back, There will be two of you, and since there wasnt two originally the law is violated. Thats another reason i disagree with backwards time travel.
