Time travel

[Explode]

While I was on the phone with one of my friends, the topic of time travel came up. She mentioned time travel to her boyfriend, and he believes that time travel is only possible in the future. She told me that he said he heared about a plane that went so fast that it went 2 seconds in the future, and first thing i thought of was "Yeah...no" But I put some thought into it. If a plane was traveling so fast that it went 2 seconds into the future, then it would dissaprear, and it wouldn't be able to travel back in time. So now imagine that you went 2 seconds in the future,after the plane did. Would the plane be there? No, because 2 seconds ago it went forward in time, therefore, it would still be in the future two seconds. So where is the plane?

I have three disagreements. 1. About the plane still being two seconds in the future, you have to ask yourself "relative to what". 2. More on relativity. The faster an object goes, the slower time becomes. It is a documented phenomenon that time dilates, noticeably as an object's speed approaches 70% of the speed of light. Clocks, synchronicity, you may have a blast looking into that. 3. Like Einstein, I believe that time does not exist; it is only an illusion. We can't time travel because there really is nowhere to travel. Now is the only time that exists. Our only option would be to travel from "now" to "now"...is that really traveling?

I believe in most of what you say. But time being am illusion? It can be measured. It may not be a constant as once thought but I did think it existed from our vantage point. I guess if existence in general can be considered illusory and time obviously being part of our existence, then it can be said it does not exist, in theory. To our minds or conscious, it may be one streaming string of events that cannot be paralleled to anything of itself. But time in the aspect of science is another matter isn't it?

I'll tell you how to travel back in time: 1. Create a Lorentzian wormhole. 2. Transport the wormhole through spacetime at a very fast speed (so that they effects are noticeable). 3. Step through it. That's it...you've traveled back in time... Of course we aren't even sure if Lorentzian wormholes exist, but they show up in General Relativity so often and so easily that scientists think that they could exist. Also, to keep open a Lorentzian wormhole long enough and large enough to let a person step through would require a TREMENDOUS amount of energy. Finally...Stephen Hawkings believes that quantum physics will prevent travel back in time (important...travel into the future is very easy). And remember, Star Trek and Deep Space 9 is not science. www.scirus.com if you don't understand the things I just mentioned.

I believe right now our dimension is in 1 time period and can only be in 1 time period no matter what. Multiple time periods are only obtainable in the fourth dimension, where time can be as thick as a log or as thin as a piece of paper. in our dimension, time is as thin as drawings are in the second dimension, it can not be any thicker. therefor if anythithing was in the future or in the past it would have to xeist in the fourth dimension or higher.

Keep in mind that I have not studied physics or anything related to the subject, so everything I say is from my subjective logic. First off, everyone talks about time "travel." It's interesting to look at that phrase linguistically and see what it implies, namely the movement of one person/object/idea from one location to another. Time may be measured, but can it be mapped out in the way we would normally consider a "map"? I was just thinking this today, so my ideas on the linguistics of "time travel" is a work in progress. Anyway, as for moving forward in time, you would have to find a way to keep yourself - in addition to any space that you wished to transport - in one place, unaffected by the movement of time. Although there are different factors you would have to consider, such as physical, mental, and possibly even spiritual aspects. That means that there would have to be some sort of barrier, but the problem lies therein. How could this barrier be affected by the movement of time? In addition, you'd have to consider the consequnces of arriving at a point in the future. I mean, how would your body react to an instant change in temperature, air quality, etc. What if, in the future, you arrived only to find that the earth had been blown up or was in some way inhospitable. Then there's the matter of going back in time. I think that this is, in actuality, mathematically impossible. Regardless how accurate our system of measurement is, time can be measured in a series of numbers. The series, however, has two qualities: 1. It runs forward; and 2. it is infinite. For example, imagine a stop-watch. When you start a stop-watch, it shows you the hours, minutes, seconds, 10s of seconds, and 100s of seconds, generally. However, imagine that the list of multiples of seconds continued on into infinity. It would make sense that if you are trying to go back in time, you would have to stop time first, but that would require stopping each and every division of time, and since it is infinite, it is impossible to stop time, let alone reverse it. Along with that, if there was some way to reverse time, you would have to consider this question: Where would the person/object that is going back in time exist? It makes sense that no two solid objects can occupy the exact same space at the same time. So not only would you have to figure out how to turn time back, but how to avoid the problem of this kind of duplucity. As for alternate dimensions, I've been putting a lot of thought into that, mainly for literary purposes (eg. writing a book). I might post that later. All in all, I like writing this stuff out. It often helps me to solidify my ideas, but also come up with new ones. As I said, it's a work in progress.

traveling into the future is very possible and happens all the time. i think its called the theory of relativity, when an object travels it goes into the future a little bit, even if its impossible to notice. the faster the object goes, the more time is warped. so next time you get pulled over for speeding, just tell the cop you were trying to go into the future

The one going at a large percentage of the speed of light (hypothetically) would feel as though time was normal, but time is much different with things at rest with say, earth. But I'm no authority much on it either... Here's a little analogy I read... Say you're on a bus and you throw a ball into the air. You see the ball go straight up and straight down. Someone standing at rest with the road will see the ball go in a big arc. You feel that the ball went a shorter distance, and the other person sees a longer distance. It's more perception than "traveling" into the future."

Lol, no that has nothing to do with the theory of relativity/time travel Wait... you say after flying for 2 hours and ,staying in the time zone, you arrive 2 and a half hours later? That's wrong sorry But time zones aren't the same thing as time travel lol...

Hrm... that depends on how fast you're moving. Check out this formula... t'=t X sqrt(1-v^2) This is out of a book I have... t prime is the time between two events measured in a reference frame where they occur at the same place. t is is the time between events measured in a reference frame where they occur at different places. V is the relative speed of the two reference frames, as a fraction of C. Now even if you're traveling at 1 million meters per second (2,236,936.29 miles per hour... which is about 5600 times faster than any commercial airplane), for say... 2 hours (as in your example)... well, you would only be going 1.11300*10^-5 of an hour into the future (this is 40.06800 milliseconds). Based on these equations... it seems pretty damn unlikely that the plane went 2 seconds into the future. There is a plane that had clocks on that went into the future... but that might have been two BILLIONTHS of a second into the future. And the two seconds forward in time is not actually the future, it's a perception. It's not as if the plane "dissapears." The going into space thing for an hour and spending 2 hours isn't true either. I dunno where you came up with that.

I think you have to be carful with your wording on this subject as time is a man made thing and so you can easily move onto the grounds of uncertinty, If a plan did go two seconds into the futur, I believe that the amount of time is so insignificant to notice that, even ifs flight was recoreded then it would just be seen a a quick fault, the plane probably wouldn't be their as it has in a way avoided times grasp and so the main question is to travel to the futur you arnt around for the time since you travel so where do you go, to get their as you arnt held by the laws of time on the earth

And I think you don't understand what the theory of relativity considers "time travel." You dont' disappear and suddenly reappear into the future. How old are you, by the way?

[Kyhaar]

I had a dream about going back in time... I was worried that I would alter time. I was lucid in that dream (lol- "When I wake up from this dream everything will eb back to normal")

[Kyhaar]

I saw this NOVA video one time. If you go slower than the speed of light, you are moving. But what happens if you go faster than the speed of light? Will you freeze? Will you go back in time?

[Howie]

I believe in short that if your were to reach the speed of light that time would stand still. That may have changed. Ofcoarse things change when the vantage point changes but the core argument would remain the same would it not? I know that a small time dilation occurs even it very fast aircraft from point A to point B. The faster you go the more evident it becomes. I read something in the order of Time sensitive muons and the ability to record the time differential when they were calculated form Mt Washington observatory. I read that a long time ago. It is vague. Don't quote me on that. Or anything for that matter!

Originally posted by Howetzer I know that a small time dilation occurs even it very fast aircraft from point A to point B. The faster you go the more evident it becomes. and if it were possible to travel fast enough, you would eventually be able to distort time so much that time on earth would fly by, while time aboard the aircraft wouldn't seem any different. its really hard to imagine, but you need a physics professional to explain it to you, because when i was taught it in highschool it made total sense or wikipedia http://en.wikipedia.org/wiki/Time_dilation

That is why it is hard for some to understand. By you in the aircraft slowing down you are in one sense going into the future. OR better yet you are putting the future on hold while on earth it would remain the same. That would suck. You are on a vessel for a week and come back to find the earth, well probably still at war. ha ha

People with the theory of relitivity it's rediculous just because something goes against it doesnt mean its incorrect or a stupid view, it doesnt even exist properly in the universe look at galaxys the further you move outwards and they still go at teh same speed so in other words it is not universally correct in everything

For one.. saying how fast they go is really ambiguous - relative to what? Relative to us, the farther out you go, the faster things are moving. So you're quite wrong.

[darklordofall]

Learn to read things, in galaxys speed is constant at any distance, you want to know where, well it was first found out, in the search for the elusive dark matter, it was also this fact that changed the searchs direction and so doing made the idea of dark energy come into play, moron.

[Howie]

Some big theories with little to back them up! It is hard to put into context these ideas without a bit more information. Elaborate your claims. They are too vague.

[existentialist]

Hi everyone im new here and 16 so have pity well i belive that time travel to the past is posible, but traveling to the future, is ambigous, to what future would you arrive to, ( that if free will does exist) for example, say that you traveled to the past, fine, but when you traveled to your present aagain you wouldnt be able to go back to the one you last left, if you cant hold this, just picture it as a zipper, the past is zipped, you know one past, the present is the zipper, but the future has, not two strands like a real zipper, but an infinity of strands, and as time goes by, those posible realities(strands) are "zipped up" becoming a real reality(one strand). but, i am only a child, so i would like you guys to help me out on my reasoning, thanks
