Time Travel

[Minh]

Sorry if there's a topic on this already, but ^-^

What are your thoughts on this? can a time machine be create? is time travel possible? to change the pass? etc.

I'll post some of my theory when I see some ^-^

[Nonexistinghero]

No, time is just something in peoples mind. Everything ages. Some things age faster than others, that's it.

It's just that people needed something to name it. The name of it, is time. Over the years people went crazy and started thinking about all kinds of crazy theories, in order to travel through time. But they forgot that time is just a word, just something fictional that people made up to keep track of what they did, and are going to do.

Still, if some people insist that time is something else other than just a word, answer me this: What can go back in time? Elements, no. People in fast cars? No, since it's just their brains that start working faster and make it seem like time goes slower.

There's lots of bullshit people made up a long time ago, but that people don't research right now or properly think about. Just think about 4 elements for example... Earth, wind, water and fire are the elements, they say. But just think about things that these elements don't create, can't create.

[Rurouni]

Do I think time travel is possible? No. What's done is done, and it's best to leave it at that. I don't believe in the possibility of being able to travel back or forward in time.

[meweiss182]

i was reading something about this that had to do with physics and the space time continuim(sp?) but wat it all comes down to basically is time is in the mind technically there is no time we just associate some way to run our lives safely and constructively so we invented something to keep us on the right track. so technically no it is impossible to go to something that technically doesnt exist :)

[AlphaKeny1]

The theory of time travel as perpetuated by the popular media is total BS. However, if we created a vessel that could travel faster than the speed of light and could also contain a human to the point where he is unharmed by the G's, then theoretically he could travel into the future. We will never know this, however, since it's not possible for a human to travel so quickly.

[composer of requiems]

It isn't really travelling into the future... it's more like cramming more years into the rest of the world while he's away so when he comes back, he's covered less time for himself...

[Drak]

As we all know time travel sucks. While going forward in time is generally accepted as safe and a fun pass-time (no pun intended) traveling into the past is ALWAYS a bad idea... i think. There is only one definite i have found and that is if time can be changed, the further you go back in time the larger the effect a action would have on the present. But that’s it... then comes the part that makes my ears bleed: If you go back in time to change a event, that event would already be changed and so you would have no reason to go back in time to change the event. That’s where the words "paradox" and "end of the universe" come into play...and nobody wants that.
But there are a lot of different theories like "the past cant be changed" and "the universe will correct itself" so I’m curious to see if anyone has any input on this.

[composer of requiems]

There's always the alternate universes theory... but I don't agree with going back or forth in time, since to me time isn't really a dimension but just a way of knowing what happened before and what happened after. So everything's just changing, and if nothing changes, there's no time.

[NinjaJedi007]

as appealing as time travel is, i believe no time machine should ever be created. if created it should be found and destroyed immediately. it would be really interesting to go through time but it seems like there are so many problems that it would bring... like catastrophic events.

[Dagda_Mor]

I just laugh at how people theorize that you could go back in time but any attempt to change the past would be stopped by fate; try to shoot Hitler and he'll move aside, or a tree will fall on you, or a car will speed in front of him at the last second. By going back in time you are automatically changing the past by your displacement of air molecules.
To me, time travel is a complete impossibility.

[Arisa Phoenixstar]

There are so many theories revolving around time travel. There is the theory presented in movies like Back to the Future, where he prevents his mom from falling in love with his dad and he starts to dissapear from a picture? There's also things like the butterfly effect (not specifically reffering to the movie). There's also people who go back trying to fix something, and wind up screwing things up. Also, you have the movie paycheck, where knowing the future causes those things to happen, like worrying about an epidemic and crowding the sick together and creating the problem. Time travel's a very difficult thing, probably not very good with mess with.

[santosj]

I think it is pretty acceptable theory that if you were to go back in time and cause a disturbance that a new alternate dimension that flow side by side. Lets say for example, you would go back in time and kill your grandfather or father. The paradox is that if you were to kill your grandfather, then you would never be born. If so, then you couldn't have gone back to kill your grandfather so you would still be alive.

So instead, the time line after you kill your grandfather would exist by the timeline where your grandfather is still alive. In reality, if you go by that timeline, Marty would still exist even if his parents didn't get together. The problem exists when trying to go back to the future (not the movie) and which dimension you would travel to. Since it was you that disrupted the future the timeline I would assume the person would travel to is the new one. The one that existed would still exist but the person would be trapped in a dimension of which he was never born. This would cause some interesting results because technically, he doesn't exist and if he doesn't exist then he can do whatever he wants.

This theory also gives proof to the reason why we don't feel anything that could have happened by someone going back in time and killing Hitler. If that was the case then the timeline would be split and we would still exist in the timeline where he was still alive. I suppose that the timeline next to us is better or worse off depending on what the person does.

[crabman]

Actually, it's been somewhat proven by math that you can travel in time. Except the exact time when the machine was made is the only time you'll be able to move around from. It's like a pivot point that the "new" beginning of time. So that means you can move forward and backwards in time as long as it was AFTER the time the machine was built. That or you could only move foward in time. Can never go back or soemthing like that. it's one or the other.

That means we can't screw up the past even if we wanted to. We can only mess with the present and future. Basically because it hasn't happened yet. So ya, time travel probrably won't be of much use except for a really good history lesson in the future. Or if it means you can move backwards and forwards in time, we'll have infinately better technology and easier living.

[santosj]

I was thinking about the Worm Hole time travel theory but then again, that is improbable since it is kind of impossible to create a wormhole and then make one that could go back in time. I believe that one could be possible in the far future but not now.

[Ninja48]

You can travel to the future.
I remember I saw on the discovery channel that they set 2 clocks, one on the ground and one on a very fast plane. When the plane landed and they compared the clocks, they saw that the one on the ground was like .000001 behind the one from the plane.

lol, And Steven Hawkings said "If a time machine was invented sometime in the future, why arn't there tourists from the future visiting us?" or something like that.

[Nonexistinghero]

I wrote this in a time travel thread in the philosofical part of the forum. I'm too lazy to retype it...

[Ninja48]

I think they've already proved that time is a thing. =\

[Nonexistinghero]

I think they've already proved that time is a thing. =\

Uh... no. And I read all. The theories are fun to read though.

[Ninja48]

Uh... no. And I read all. The theories are fun to read though.
I saw it on the discovery channel or something. Time is like a dimension...and uh...well they said alot of stuff. Like all this quantum physics and whatnot.

And yeah, theories are fun to read. I just read about the M Theory.

It's not even been proven other dimensions exist. The whole dimension thing is based on, "What if?" But the choice you made can't be changed. The things you've done can't be changed. Time is about the same (you can only look back on it), so that's why they're being put together. But if you were to look at dimension traveling and time traveling... Time traveling is on a whole different level. Even dimensions are inferior. Even god is inferior. No one can stop time from going further. One who controls time, controls all. That's one of the reasons that I think time is what I think it is. Just something in the mind. Something a human mind just can't comprehend because it's not actually there.

*read M-theory*

[Cinnabon]

Who need time travel? The universe is suspected to have well over ten hundred trillion planets, it is theorized that with a number so great there are probably well over 20 planets populated by humans at the same technological level! And possibly thousands of others at different levels. Elves do exist somewhere out there! Who the hell needs time travel?

wtf are you talking about? Elves and planets and WAT?!?!?!?!

U know, not all clocks are the same......... Alot of them are kinda off from each other. If you ddin't know already, you have to reset your car clock every now and again cuz it gets really really off.

[Cinnabon]

I'm saying it has been theorized that there is so many planets in even the known universe that there is a more then 90% chance there is probably elf like people out there, and even better things :)

[crabman]

so uh.... wats do elves have to do with time travel?

[Cinnabon]

I'm saying we don't need time travel

[Nonexistinghero]

You make a good point Cinnabon. If someone proclaims to have traveled through time, it can very well be someone who basically just teleported to this planet.

[santosj]

Teleportation is another theory for another time. I think we are getting ahead of ourselves but teleportation isn't really outside the scope of time travel. Well, actually it is.

Time

I once asked my physics teacher, if someone was floating out in space, would time go faster for them. What I mean is not orbiting the earth or the sun but outside the influences of gravity.

Figuring how fast the Earth is orbiting the sun and rotationing I'll say we are aging fairly slowly. The closer one gets to the speed of light the slower time gets. Doesn't mean time stops or gets slower, just our measurements of time gets slower.

[Sabator]

Don't forget, if you travelled back in time 100 years, to your exact location, the Earth would probably be far away. the Universe is constantly expanding at a fast rate. We're basially riding the aftermatch of an explosion.

[Sabaku no Ira]

According to Einstein's Theory of Relativity, it is possible to travel forward in time but not backwards. This is because time slows down when you're moving (simplified version: the truth is far more complicated than this).

[Arisa Phoenixstar]

Is that really traveling in time though? I mean, I guess it could be considered so, but if you hold to the theory of realativity, if you go really fast, at say the speed of light, time will pass slow, if you went a way from earth and then came back, what seemed to you like a year could really be like a thousand. I think that's more like being pulled out of time then travelling forward. But that might not be entirely correct, and I'm not saying that time travel is not possible, but from what I know about realitivity and what not that's just how it seems to me in that particular situation.

[santosj]

Yeah, it is actually traveling through time even if you are traveling to the future. The only problem is that you would never be able to go back to your own time afterwards.

[KK]

Merge0rzzz time.
Continue....

[Sentios]

According to Einstein's Theory of Relativity, it is possible to travel forward in time but not backwards. This is because time slows down when you're moving (simplified version: the truth is far more complicated than this).
This is hard to counter I must say. However if time is an illusion create by the mind or even if it is a real thing your bodies cells would divide and die at the same rate unless you were to do something increase the life span of the cells or the number of times they can divide before the DNA wears out (you'd have to be put in stasis). but if you can do that you have need to go through time because you have increased longevity.

So I think I'll put in my own theory now, the existance of alternate dimensions/existences. In my theory there are events that cause everything on a planet(animals, plants, the very planet itself) to replicate exact copies without any concious knowledge of it happening. Now even though this new copy planet existance on some undectable level doesn't mean that it has to follow the same course of events infact the people may behave differently even though they are "copies" of each other due to their free will.

And that means that these alternate existances can have different tech levels meaning they seem to be different points in time. So this then means that the alternate existance could be percieved as the past.

For instance in one alternate existance Hitler could have found longevity and then done as he pleased or it might not even be the same Hitler just an imitator that thinks and act like Hitler.

Yes there are a lot of variables but space is vast and so far it's limitless, as well as there is an unknown amount of alternate existances, meaning the possiblities lining up in the way I described could be true somewhere.

My theory can also be used to describe that no one has original ideas they mearly witness the events of another existence in their mind, hence it occurs the same way as an idea. So that means in this variation of my theory that there are alternate existances where each anime storyline (or any storyline even) take place.

[korican04]

I think you can only go into the future and not the past. So you can just live your life and you are time traveling, but there is still a possibility of you going "into" the future. Of course you need to go the speed of light and hope that your mass doesn't become infinite and you die.

[santosj]

You can't go the speed of light, that is the whole point. It would take too much energy to even get as fast we do. We have the technology to past the speed of speed of sound five or six times but that isn't close to the speed of light. There are particles that can go faster than the speed of light and I don't know how to spell the name but like you said we would need some pretty heavy shielding to keep our bodies intact as we get up near the range of the speed of light. Also who says we even need to go the speed of light. I think going half the speed of light is great. It may take four times as long to get to the destination but it would still put a lot of places in arm's length.

Again the only problem is by the time we get to the destination everyone we know would be dead because of the time that had past on Earth relative to the time it took to get to the star system is so great. That is the whole problem. What would be a year of travel time would be four to eight years on Earth.

If you think about it, there are some places that time is slower or faster than on the Earth.

[Neverfate]

We exist in four dimensions. We have length, width, and height, and we are moving along the fourth axis which is time. The counting of time is an arbitrary construction of mankind. The flow of time itself is resolute. Saying that all things move forward in time may be true, but as we know little of the nature of time we can only assume this is true. However, time IS relative. The passage of time is different in different situations. The idea that time is static is as ridiculous as Newtons idea that space is static. And just as space moves and has shape and stretches and circles, so does time. Time travel is definitely in the range of the believable, even if it is not possible for us now. Our research into gravitonics is helping us on this front.

For those of you nay sayers, what makes you think that time has not already been altered? Once history is changed, all history would change to match it right? So you wouldn't even know if it was changed in the first place. That is unless we start getting into quantum time, world streams, and the lightspeed/mass ratio. My point is that if time is not static, why couldn't we bend in back onto itself?

I don't know if elves exist LOL ... But I sure hope that Temari does...Damn she is sexy.


Time travel if it is to exist, it's gonna be in about 30 000 years. Maybe nonexistinghero will still exist but not me.

U know, not all clocks are the same......... Alot of them are kinda off from each other. If you ddin't know already, you have to reset your car clock every now and again cuz it gets really really off.
o_O It was a scientific expirement. They set VERY accurate clocks at the same time VERY accurately. They didn't just get off a plane and happened to notice their watch was off 5 minutes from the clocks they saw at the airport.

[santosj]

There are those who get it and those who will never understand. Which one am I? I'm probably in the latter.

If you want to believe in the big bang then you should know that dimensions existed in the ball of energy that was the universe. Time was said to be unstable during the first stage of the universe creation so it is their guess that you couldn't travel past that point in the past and you can't travel beyond the same point in the future.

when you were talking about particles that go faster than the speed of light do you mean Tachyons or Virtual Photons?

you're right for you to get the affect of future time traveling you just need to go really fast but not the speed of light. If everyone around you ages faster than you and new things have arrisen haven't you gone into the future? <--rhetorical question, i've studied i alot physics but it's not worth discussing here in the NARUTO FORUMS lol.

[martryn]

Well, I'm not going to sift through three pages of posts, so if I'm being redundant, just call me an idiot.

Several things need to be pointed out.

1) Time travel can't be possible, unless it is in a forward direction. The second law of thermodynamics says this.

2) Time is relative. You can time travel by allowing everything else go faster than you, but I don't see how that is possible. We exist inside a system, and with the speed the universe is expanding, and with us being on a planet that's both revolving and rotating, there is so much speed there that you would have to be off world to do it. And because the universe is practically expanding at a rate MUCH MUCH faster than the earth is rotating/revolving, ect. then you would have to proceed to travel to the center of the universe where the universe isn't expanding hardly at all. But to do that you have to go against the universe's expansion and to do so requires you to travel at the speed of light or faster.

See, when the Big Bang occured, the universe expanded at a rate faster than the speed of light, and light from that first moment hasn't reached the edge of the universe, and this was trillions of years ago. How far do you think the center of the universe is? So that in itself rules out traveling into the future.

3) In all the Sci Fi movies of time traveling, does no one stop and think about the Earth's rotation, revolution, the rotation of the solar system, the galaxy, and the ever-expanding universe. These people who travel through time aren't just traveling through time, they're also traveling through space, meaning that even Sci Fi time travel is impractical (did that sentence even come out of my mouth?)

[Nonexistinghero]

1) I agree

2) It's not proven the universe expands. I do have a bit of a theory though. At the ends of the universe, there is nothing. It does not seem to end either. You know those games where there are infinite hallways, and where you have to walk back the same amount of hallways to return? Space is probably the same thing like that. At least, that's what I think. Either way, none of those theories can be proven just yet.

And the Big Bang is just a theory. The universe was already there before it occured, i'm pretty sure of that.

3) It's not just Sci-Fi movies that defy logic. It's in A LOT of movies. It's just sloppy thinking of the writers most of the time. But that's why they're just movies. Those movies are there to entertain. Documentaries are supposed to make people smarter.

[falconmain]

some of these theories are alittle out there. we know that the faster you go the slower your time is relative someone not moving as fast. This has kinda been proven based on astronauts and satellites they run at a different time length. with satellites that have adjusted the clocks to run at a speed that takes into effect the slowing and thus matches up with earth time. I hate to say this but its all kinda relative to how you measure time.

personally I think that you live moment to moment you can effect how fast or slow that moment is relative to other peoples time but you can't go back and redo a moment you already lived.

[martryn]

Its true that it hasn't been proven that the universe is expanding, but most scientists do not deny all the evidence that supports an expanding universe. If it's not expanding, it is at least moving.

[Nonexistinghero]

Sometime in my lifetime... I will find out exactly what it is. And I won't tell people... because they should figure it out for themselves.

[kunoichi_doctor22]

i read in a couple of journals and newspapers a couple of years back that there was a german scientists late back in the 1950's whom had theories based on time machines and he was actually going to build it but i think the government didn't allow him..it was all a hush hush situation

[Nonexistinghero]

Just because he wanted to build a time machine, and could travel through time theoratically, doesn't mean it would work.

Because those theories are more than likely wrong or imperfect.

[kunoichi_doctor22]

yea i know...but it would be really fun if it did work

[Nonexistinghero]

If you would go forward into the future, it means leaving everything else behind. You won't be able to return. So... I don't see what would be fun about it. You'll end up in a world you didn't grow up with. Peoples mindset will be different too. In the worst case you'll end up becoming crazy.

[santosj]

Yeah, they may have used the atomic clocks that measure the life of a single atom that is said to last exactly one second. Every other clock is slowly set back as the measurements is offset by the margin of error inherit in the clock's timer.

[netorie]

Time travel could be possible...but not likely...

[Ddark]

It HAS been proven theoraticaly that time changes in relevance due to energy. As such, it seems to be a thing, rather than a not-thing, and more so - a thing probably connected with the rest of the things.

As for time travelm as far as I know its only possible to go forward in time, although it is possible to, using heavy distortions due to energy, make time go faster (This may be gravitational, or velicity, or whateveR).

[Zatoichi inactive]

Here is an illogical situation about time travel: Say that a person goes back in time and kills their parent. Then they would not exist, destroying their mind, body and whatever they will do. Thus, they would not have gone back in time. Their parent would then not die and they would not be destroyed. How would that work?

[falconmain]

actually its not to illogical if you consider that every moment could break off into its own existance. so when you travel back in time and change something you are now traveling along a different path in time.

[shinjuu]

If time travel were to exist then people from the future could be here right now.. but they arent or not showing themselves so time travel doesnt exist(im losing my own thoughts here lol)

Well if you wanna travel back in time just make a VR machine that allows you to live in the past. It wont hurt anybody and im sure in the future they can make such a machine that it really looks like you are in the past..

[ANBU87]

time machines can't be built. if it could, hitler would never have come to power. ww1 might not have even started.

[Solus]

possible? im not sure, but even if it is possible its my opinion that the past is best left alone. we get one chance to do everything that's how its supposed to work. if we screw we have to fix or mistakes and learn from it, if we could mold the past, present, and future to our every whim we would only be playing god, we would learn nothing, and we would all become soulless arrogant amoral bastards. even if it is possible to change the past, we shouldnt whether it leads to fortune or trouble, its not right.


ps: did anyone here about that MIT time travelers convention?

[kurisawa]

i've seen a video of hg wells claiming time travel was possible. correct me if im wrong, i heard he also had an 'experience' with it or something?

[dmby]

time machines can't be built. if it could, hitler would never have come to power. ww1 might not have even started.

No. Not at all. We have a hard time comprehending what would happen if you went back in time. But you cannot know the laws of something we (supposedly) have never witnessed. Oh well. It is a paradox, time travel is. But is is theoretically possible to travel forward in time...

[Haik]

Don't ever say: let's kill some time.
Time will answer: I already killed so many of you.

Timetravel? you kiddin me right??

[theoneandonly]

if we change the past it will not affect the present time but it will create another universe which that incident did or did not happen due to our alterations...

[Geron Kizan]

People think that time flows in a stream like a river, which it does not. See, we, mankind invented time. We made its units of measurement, we made its importance, everything. Anyway, we would need to interact not only with time but also the universe that surrounds time.

In order for humans to jump around in time, we would have to think not three dimensionally like all humans thing, but four dimensional, in which the fourth dimension is time.

So all in all, time travel seems impossible until we can achieve the fourth dimension and control it.

[Q]

Time travel will never happen because if someone actually does manage to create a time-travel machine, someone will go into the past and do something that keeps time travel from being invented.

Dilation of time is theoretically possible at high relativistic speeds, just as dilation of length. As a result, something traveling at a high relativistic speed would appear to move through more time from the reference point of Earth, and would therefore age less in relation to objects on Earth.

[Devonin]

Time travel is perfectly possible in theory. Time travel to the past is doable, and causes no paradox whatsoever. You actually -cannot- change the timeline if you go to the past, because you were already there and did everything you are going to do.

Say you decided to travel back in time to 1850. Seeing as we're now well past 1850, you aren't going to suddenly appear in 1850 and screw up the future by your actions. You were -already- there and the current present and all events between 1850 and now -are- the effects of what you did when you went back in time. There is only one 1850, and if you are in fact going to travel back in time in 20 years -to- 1850, the one 1850 which already happened -had- you in it.

Correct, there is no paradox ASSUMING that time is indeed the fourth dimension (which means you can move anywhere in the dimension of time given the right resources)

[Sublime]

It might be possible one day but I don't think we can change anything even if we're able to go backwards in time.

Going into the future is more likely to happen. I heard somewhere that if you go around in a circular motion like a merry-go-round, at the speed of light or close to it, time will seem to move at a superfast rate ( like you're fast forwarding a dvd movie ) and once you stop you'll be years ahead in time.

[Devonin]

I've been arguing that Time is a fourth spatial dimension for -years- (pun intended)

I've always been bothered by sci-fi that goes crazy over "OMG you'll change the timeline!" nonsense when they try to handle time travel. it's been done well a few times, primarily on Star Trek. "Hell Week" I and II from Voyager, and "Time's Arrow" I and II from T:NG come to mind as examples of an actual understanding of the mechanics of time travel and timeline modification with its consequences.

-vash: i see someone else knows einstein's theories

-vash again: correct, u cant just assume all the variables, there could been some weve never even thought of

-slice and dice: i think uve seen too many superfriends episodes

-devonin again: once again all those shows were merely assuming the physics involved there is no way to prove any theory as of yet. and wuts more theyre tv shows, pure works of fiction nothin more.

[CrazyMoronX]

Well the universal concept is, if time travel was possible, we would have already seen tourists from the future. However, time travel is possible in a sense. Cryogenic stasis will make one "travel" into the future in a manner of speaking. That person does not age, and thus to that person he or she is travelling to the future. Of course that isn' the classic sense of time travel.

I think it's possible to suspend your aging for a period of time and thus travel to the future by coming close to or exceding the speed of light, it's proven that time moves slower at near-light speeds. However, reverse time travel is NOT possible in any manner of speaking. In short any conventional time travel is a one-way ticket to the future.

Reverse time travel creates far too many problems to ever be realized, possible or impossible. Time paradoxes are the biggest ones, and changing the course of history would create an infinite string of unknown events. I'd say time is just a continual force forever moving onward, and never once going back. If you were able to reverse time, then wouldn't you reverse the creation of the machine itself, really only creating an infinite loop of creating the machine and reversing time?

[Geron Kizan]

-geron kizan: maybe, but i think uve been watchin too many sci-fi channel movies...

Wrong! I read too many books, legitimate ones too.

[Devonin]

-devonlin(sic): ur(sic) interpretation also makes sense, but once again i impose the question: how can u(sic) know for sure unless u(sic) experience it first had(sic)?

I'm quite positive you believe in the existence of all -sorts- of things you've never experienced first hand. The end result of my interpretation is that it allows time travel to be possible, and neatly solves all ofthe contradictions inherent in it. While that entire chain of logic is contingent on the eventual discovery of time travel, it doesn't change the fact that my arguement is sound as to how it -might- operate.

devonin again: once again all those shows were merely assuming the physics involved there is no way to prove any theory as of yet. and wuts more theyre tv shows, pure works of fiction nothin more.

See above, about how a) ANY statement -whatsoever- about time travel is by definition theoretical and b) All I was trying to do was propose a method that both makes sense to my understanding of how time operates, and is a philosophically sound line of logic with respect to paradoxical objections.

[omnislasher_VII]

I doubt it. I say when the day comes, the Universe as we know it will be destroyed.

[KageMane]

Someone said u can go back in time by traveling faster than light speed (c=300.000 Km/s). That is physically impossible. To reach c, u'd need an infinite amount of energy. What is possible is, for example, to travel at 90% of c and thus slow the time by 50%. Then if u spend a year travelling round the universe with 0.9c, ud be back to earth and two years would have passed.

The only way we can go back in time is trough "worm holes". But we know little about them

[Merlin]

Well the universal concept is, if time travel was possible, we would have already seen tourists from the future.

Negative, why would people from the future appear amongst us as people we can distinguish as futuristic? How do you know what is futuristic, this is just as theoretical that the future-tourists are distguised as us, so simply said its plausible to be either.

I dont think time travel is possible until we understand what time truly is, most importantly mastering the practical systems of design in theoretical plans to be set into practice. Example:

Scientist, day before experiment, notes that in three seconds(variable strectch) on his table a white rat should appear (it could be black, but this is reasonsed) if the rat appears, the experiment will of course succeed the other day. Then, in practice, one must succeed in the experiment or the time-flow will become unstable.

To master this takes a major degree in mathmatics and physics. The problems would be rather annoying though, there are two theories on time for this example:
1- Time is already designed, a constant, a leap to 1865 will be just as much a leap today as tommorow
2- Time will expand as an ellipse, the aforementioned leaps til 1865 will require more efficiency the following day.

So how would one be able to account for a time leap project when the values are variable? I think we are so lost in thinking ahead of our status that we wont be able to construct devices to master or understand time. Not yet that is

[akuma no omoigakenai saku]

there was too much physics babble, so I didn't read all of the posts.

1st - I agree with whoever said that you can't know something until you experience it. (I had a really dumb argument with a friend once when he said the he knew that Sid didn't kill Nancy on purpose, and I said the he believed it but couldn't actually know it. We fought for like half an hour and then proceded to drink).

2nd - the existence of time travel is possible, but not very likely.

3rd - the whole going back in time to kill hitler thing is moot, because the hypothetic people who will invent time travel might not be willing to change the past, as it could lead to a nuclear winter or something. Also, if hitler was killed, there would have been no war, so there would have been no reason to go back and kill him, so he wouldn't have been kill, so there would be a war, so they would go back and kill him, so there wouldn't be a war, so they wouldn't have had to............

4th - almost every time travel movie or show has glaring paradox.. (what the hell is the plural of paradox? paradoxes?). The terminator and T2 had a bunch because whatshisname couldn't have been alive to start the cycle of being John Connor's father, and because if it was the chip from the 1st one that taught people how to make the machines, how did the whole thing start? and if they stop the machines from being invented, thhere would be no time machine, so they couldn't go back to stop ...blah blah blah.

there was also one in the old X-men cartoon that pissed me off when I was a kid. A guy goes back to kill someone, and then goes forward and blows up the time machine 5 minutes before he got in it the 1st time, which wouldn't work because of another friggin' paradox. it ruined my whole childhood.

5th - you need a flux capacitor

[martryn]

Well, I'm not going to sift through three pages of posts, so if I'm being redundant, just call me an idiot.

Several things need to be pointed out.

1) Time travel can't be possible, unless it is in a forward direction. The second law of thermodynamics says this.

2) Time is relative. You can time travel by allowing everything else go faster than you, but I don't see how that is possible. We exist inside a system, and with the speed the universe is expanding, and with us being on a planet that's both revolving and rotating, there is so much speed there that you would have to be off world to do it. And because the universe is practically expanding at a rate MUCH MUCH faster than the earth is rotating/revolving, ect. then you would have to proceed to travel to the center of the universe where the universe isn't expanding hardly at all. But to do that you have to go against the universe's expansion and to do so requires you to travel at the speed of light or faster.

See, when the Big Bang occured, the universe expanded at a rate faster than the speed of light, and light from that first moment hasn't reached the edge of the universe, and this was trillions of years ago. How far do you think the center of the universe is? So that in itself rules out traveling into the future.

3) In all the Sci Fi movies of time traveling, does no one stop and think about the Earth's rotation, revolution, the rotation of the solar system, the galaxy, and the ever-expanding universe. These people who travel through time aren't just traveling through time, they're also traveling through space, meaning that even Sci Fi time travel is impractical (did that sentence even come out of my mouth?)

Damn, that was a great post even the second time. In case people weren't paying attention to events that occured three months ago.

[akuma no omoigakenai saku]

despite the length of my last post, there is something I forgot to say.

6th - the whole thing about time being only in the mind is foolishly somantic. The way I see it, the debate is like that aggravating tree falling in the forest one. If you define sould as the vibration of air molecules, the answer is probably yes. If you define sound as the ear's interpretation of those vibration, the answer is definitely no. The only sure answer is that it is impossible to know, since the whole process is dependent on the removal of any way to prove it one way or the other. maybe the mad hatter will pop ass first out of a woodchucks nostril and and disintegrate the tree with cheese. Not plausible...but...possible? you tell me.

anyhoo, time is change, and would exist without anyone to name it. clocks don't create time, they measure it. if there was no such thing as a gallon, it doesn't mean that liquid would not exist. I know that time is different because you can measure an inch and it's still there, and then you can measure a pound and it will still be there, but when you measure a minute it's gone, but that's PBS Kids stuff, so humbug.

the notion time might be a human invention, but the passage of time is just an observable phenomena. If we all dissappeared, it would still be out their phenomena-ing, it just wouldn't have us poking it periodically to ask what's up?

anyway. I'm an idiot and I don't understand science. pointless discussions about definitions of words and meanings that have no real answers because they aren't straight enough questions to deserve them, now that's where I shine.

[tootaa18]

time is something we have no control of

can you make the time go faster?????
can you make it go slower????

if you could do that maybe then you could travel back and forth in time ^^

[martryn]

can you make the time go faster?????
can you make it go slower????

See, this is part of the point. You can't make your time go faster or slower (unless you're Data and you turn off your internal clock while the water is attempting to boil), but you can make other people's times go faster and slower by moving in relation to them.

[tootaa18]

so you`re saying that if you move faster than the universe you will be able to travel to the future???because of the Earth rutation???

this is similar to a Film Reel

it contains of a large amount of pictures. and every time it rotates the pictures change and the movie continues, and you can move it faster if you wanna see the ending

but the universe isn`t a group of multiple pictures that you can fast forward or rewind any time you want. it just a single lonely picture ^^

[martryn]

No, I'm saying that if the Universe moves faster than you you can travel to the future.

Earth's rotation really doesn't factor in.

And I don't really understand your analogy.

Actually, I'd say a film reel is a much better metaphor (or simile, depending on how you phrase the sumbitch) for the universe. A picture is static and does not experience change. A film reel is dynamic, like the world, as the images in the reel are constantly changing.

Of course, that doesn't prove, or even suggest, that time travel must be possible. Just because something is moving, doesn't mean you can change the speed. If there is no way to change the speed, maybe one of those damn movie files that Media Player can't speed up or skip forward in would be a better analogy.

you could also say that if you could travel back in time, then you could probably make time faster/slower. I can't do either, but that doesn't mean it's impossible. I just lack the understanding to do it. Same goes for everyone else in the world (except, of course, Dr. Who).

It probably is impossible, but we can't really be sure.

[Devonin]

For everyone trying to point out that time travel can't possibly exist because we'd have tourists from the future wandering around, did it ever occur to you that we may actually just not be interesting enough for anyone to bother?

[Batman]

Time travel would be possible if other states of time have already been established, which I don't believe they have. There is only one time, the now, and slipping into someone else's now would require an invasion of conciousness.

[blacklusterseph004]

This discussion reminds me of the Hitchhikers guide mark 2. I think that time travel is indeed impossible, but it is possible to perceive time as a whole. You could thus influence events in the present to produce a possible future. (I know this is how life works anyway, but I'm suggesting more along the lines of highly accurate influencing of the future.) As for the past, that's done and gone, all we can do is learn from it.

[akuma no omoigakenai saku]

Some of these theories seem to be related to the laws of thermodynamics. Why are they the only "laws", when everything else is a "theory." I know that they are pretty straight forward and seem entirely reasonable, but that doesn't mean they are absolutes. They are just currently accepted theories about matter/energy. What if energy could be created/destroyed? Would the universe pop like an over inflated balloon?

[Q]

Note that Einstein's Theory of Relativity provides a boost for time-travel theories with the idea that time is a fourth dimension, in which changes in motion may be possible (given the right resources, of course), but does not actually provide a theory for time-travel. The idea is that speed is relative to some quantity other than time, and that an object's total speed in the four dimensions (length, width, depth, time) cannot exceed a set value (thought to be the speed of light since light would theoretically travel at the highest possible speed).

And actually, the 2nd Law of Thermodynamics does not prohibit time travel in a reverse direction; the loss of entropy could be countered by sufficient energy used to travel back in time (thus, a time-travel machine would consume a large amount of energy).

[Detri]

I find it funny that people rely on today's scientific "facts" to determine what is possible and what is not possible.

Anyways, even if time travel were possible, would you really want to do it? I think you are all watching way too much Futurama.

At least some of us are simply debating the theory of time travel. I do not want to travel through time, nor do I think it will ever happen. However, it is an interesting theory to debate.
And if we can't rely on modern physics theories for our debates, what the hell else are we supposed to rely on? Religion? *twitch*

There are many things the human mind cannot or has not yet been able to comprehend. That's the way it works, so to say something cannot happen is blasphemy.

There are plenty of other laws out there, just that these are the most famous and also the most applicable. And there is more to thermo than just these laws (says the physics major with not one, but two classes in thermo under his belt).

And the second law is, from certain stand points, not a law but a theorem that proves true over long periods of time or for a large relative area...

I'm trying to understand your argument here, you're just telling me "no" in an elaborate way.

As far as "God" goes, of course there is no proof, but you've got no facts against one existing. Not saying I believe in one or not, just saying that nothing is out of the realm of possibilities.

Think about it... everyone thought the world was flat at one point.

More accurately, I rebutted your argument by stating the problems with your logic and explaining how you could be incorrect.

That's a weak argument meant to persuade a simple-minded audience. You cannot state one event as proof that all events will follow the same model. Everyone thought molecules were made of atoms at one point, and by gosh, they were right!

Well obviously I have no facts against one existing... it's not possible to have facts against the presence of God if the religious repeat for eternity "we cannot comprehend his existence"... which is simply an out to prevent science from proving the absence of God.

Your #1 I can't comment on (don't know anything about such laws). Your #3 I agree with. #2 I have a problem with.

How do you know the universe is expanding, and how would you know how fast it is expanding? How would you know this light from the big bang hasn't yet reached the edge of the universe? How do you know there is an edge of the universe?

Obviously we cannot know whether or not these things are true, but you talk about them like they are facts... and there lies my problem.

[akuma no omoigakenai saku]

Good point Raspeh.

I'd like to ask about one part of that in a slightly different way.

How would you know this light from the big bang hasn't yet reached the edge of the universe?

Rather than "how would you know", I'd like to ask how anyone could possibly know. Wouldn't it be impossible to see light that is moving away from us. Couldn't we only observe light that had reflected off of some sort of boundary at the edge of the universe and come all the way back. That would double the travel time, and it was quite a trek to begin with. Also, if it was still expanding, any image returning from the edge of the universe would be out of date by the time it reached us.

Unless their is some theory that explains that all away. My ears are bleeding from trying to figure out all of the theories cited already.

[martryn]

Obviously we cannot know whether or not these things are true, but you talk about them like they are facts... and there lies my problem.

They are not facts, but are generally accepted by the scientific community as being true. All recent scientific evidence is in full support of my statements. The probability of them being true are much higher than it is for being false. Let me take you through a little bit of it:

How do you know the universe is expanding, and how would you know how fast it is expanding?

Because of the "red shift", the universe seems to be expanding. Galaxies are flying away from each other and all objects in space are slowly drifting away from all other objects. Simple as that.

Scientists have determined how fast the universe is expanding using.... things that I don't understand yet. I think its more of Edwin Hubble's work though. Red shift and what not.

How would you know this light from the big bang hasn't yet reached the edge of the universe?

Good. I can answer this one, sorta. We know how old the universe is (unless you are a proponent of Fred Hoyle and his "steady state" theory, which is based on Einstein's mathematical fudge factor that Hubble made obsolete). It is something like 14 billion years. We can measure the universe's age through finding the ages of chemical elements, star clusters, and white dwarf stars. And we also know how fast the speed of light is in a vacuum (unless you read Joao Magueijo), 186,000 miles per second, or about 5,869,713,600,000 miles per year. And somehow we know how far across the universe is, like its radius and what not. And apparently the universe is about 16,000,000,000 light years across, not 14,000,000,000. So if light can only travel a certain speed... and nothing can travel faster... but there is stuff 2,000,000,000 light years further than it should be able to be... well, you can draw your own conclusions.

How do you know there is an edge of the universe?

This is way too philisophical. They don't think there is an edge, but that it loops around on itself, so that if you can travel in one direction long enough you should be able to eventually reach the point of your origin again. So if you mean edge like that... There is a size to the universe. At one time (the moment of the Big Bang) the universe was smaller than the smallest atom.
======================

Course, we haven't gotten into super string theory or "inflation", but all the stuff I said is accepted as being generally true by the vast majority of the scientific community.

[I ARE 1031]

Time travel is fiction but time control is also fiction but much more desireable. The more I think about it the better it gets, day dreaming can get interesting.

[Q]

Because of the "red shift", the universe seems to be expanding. Galaxies are flying away from each other and all objects in space are slowly drifting away from all other objects. Simple as that.

Scientists have determined how fast the universe is expanding using.... things that I don't understand yet. I think its more of Edwin Hubble's work though. Red shift and what not.
First, I will correct your misstatement. Not "all" objects are drifting away from one another, although most are (especially the large ones... galaxies, for instance), and they appear to be moving away from a single point of origin. The problem with using this to measure the rate of expansion of the universe is that the universe is expanding at a rate proportional to three values: The linear speed of a given sufficienly massive object (a large galaxy), that object's distance from the point of origin (which must be calculated based on the velocities of all sufficiently massive objects), and the radius of the universe (distance from point of origin to any point on the universe's boundary). Since we do not know the location of the edge of the universe, we cannot calculate its rate of expansion (though we can calculate the percentage of volume increase it will undergo over a certain period of time).


This is way too philisophical. They don't think there is an edge, but that it loops around on itself, so that if you can travel in one direction long enough you should be able to eventually reach the point of your origin again.
For anyone who doesn't understand this, think of it as similar to the Earth... being round in four dimensions, it loops upon itself in all four (the Earth is round in three dimensions and thus loops upon itself in these three)... which would also imply that if you reach the edge of the universe, you also move to the other side in the dimension of time... time-travel, anyone?
Oh yeah, I'm so good, I managed to connect that all to time travel.

[martryn]

First, I will correct your misstatement. Not "all" objects are drifting away from one another, although most are (especially the large ones... galaxies, for instance), and they appear to be moving away from a single point of origin.

Yeah, I realize that, but it's all relative. Obviously I'm not moving away from my moniter right now, and the earth is actually drawing the moon closer to it, but for any large system (galaxies and what not) everything is moving further away from each other.

The problem with using this to measure the rate of expansion of the universe is that the universe is expanding at a rate proportional to three values: The linear speed of a given sufficienly massive object (a large galaxy), that object's distance from the point of origin (which must be calculated based on the velocities of all sufficiently massive objects), and the radius of the universe (distance from point of origin to any point on the universe's boundary). Since we do not know the location of the edge of the universe, we cannot calculate its rate of expansion (though we can calculate the percentage of volume increase it will undergo over a certain period of time).

Like I said, this is something I haven't really studied or looked into much. I'm not sure if scientists know the actual rate of expansion, but they can compare said rate to other quantities, such as the speed of light. But they do know that the universe is expanding and they can compare the rate of expansion to things, although they may not know what said rate is. I concede to your points, Vash.

which would also imply that if you reach the edge of the universe, you also move to the other side in the dimension of time... time-travel, anyone?

Ha ha ha. ....I don't think so. As you move in one direction you are not only moving farther from your point of origin, you are also approaching it from behind. There is no jump. And there are no "edges". Course, I take it you knew this and were just poking fun.

So I stand by my original point that time travel is not possible unless you somehow slow yourself down compared to everyone else around you. And you can't do this unless you allow "absolute space" to move faster than you, since absolute space is what all velocity moves relative to. And since the universe is expanding slower toward its center, then that's where you'd have to be to actually travel forward in time.

[Q]

Ha ha ha. ....I don't think so. As you move in one direction you are not only moving farther from your point of origin, you are also approaching it from behind. There is no jump. And there are no "edges". Course, I take it you knew this and were just poking fun.
Of course :amuse
I had to find something to tie it to time-travel so it was on topic :P

[Solus]

so for ur theory martryn u think that one would not actually travel in time, but would rather slow time down for themselves relatively and would need to be located at the ever expanding center of the universe making "time travel" all but useless as one would need a way to reach the center of the universe fighting the expansion of that universe (which most likely means faster than light travel) and then upon reaching the center manage to remain there fighting expansion once again for wutever desired time lapse takes place and then travel all the way back home before dieing. allthough ur theory is logical and from my knowledge theoretically sound it is relatively moot as such "time travel" would be pretty much useless would not allow one to travel backwards in time, and would not be time travel in the true sense of the word, but would rather be the opposite. it would be travelling through time as little as possible while allowing ur surroundings to continue to travel at normal speeds. it is certainly an interesting theory and a well thought out at that, but it does more to prove against the possibility/plausibility of time travel than it does for it.

i do have one question however, u said:

"And somehow we know how far across the universe is, like its radius and what not. And apparently the universe is about 16,000,000,000 light years across, not 14,000,000,000. So if light can only travel a certain speed... and nothing can travel faster... but there is stuff 2,000,000,000 light years further than it should be able to be... well, you can draw your own conclusions."

i have not seen such information on the supposed radius of the universe. how did u come by this information?

but anyway just to put my two cents in. it seems to me that discussing modern widely held theories about the universe is somewhat illogical because isnt the whole idea of time travel, especially backwards time travel, essentially going against everything we know about everything? wouldn't a "time machine" therefore be less like a travel device (such as a delorian) and more like a pottery wheel that could bend and mold physical properties to suit such a temporal excursion? wouldnt the ability to change the properties involved in physics render the discussion of those properties irrelevant?

it seems to me that that only way one could truly travle through time would be for one to change how time itself functions. and obviously if one could change how time functions one could theoretically control everything and would become in some sense a god. it is also possible that tampering w/ the physical structure of the universe could involve dire consequences. on top of that human beings as of yet dont even have the slightest clue of how one might go about bending time to their will, which means even this is just speculation, but wouldnt these relizations mean that that time travel is more trouble than its worth?

[Zhongda]

Note that (1) time travel does not necessarily involve going into the past, (2) people from the future would likely not be stupid enough to say "I'm from the future", and thus get put in an insane asylum or at the very least blow any sort of cover, (3) they would not necessarily be on any sort of mission; they might be here for observation, (4) they might not be able to affect our time, and (5) they might have already affected things and we just don't know it was people from the future.

*shrug* I'm fairly sure that is right. I read it somewhere. But my personal "library" here in my room consists of dozens of physics books from Sagan to Malone to Greene to Magueijo, ect ect. I'll see if I can't try and find it and either edit my post or post again (if I can avoid the dreaded DP).

[Narras]

This is just my opinion but, I think time travel is impossible. If you could time travel, wouldn't time still be going in your point of view? Ehh...this just goes over to my weird ideas of different dimensions and all that nonsense. =P

[Chintsuzai]

I think it could be possible.. but then again maybe not. It depends on how far technology gets in the future.. but personally I wouldn't want to know my future. ^^ I'd rather it just be a surprise.. XD

[Kakashi_Love]

Time travel is not possible because time does not exist. Time is just a concept created in our minds to record CHANGE.
Therefore, there is no way we could go backward or forward in time. Once a change happen whether physical or chemical...it happens. Even if you try to undo it, it will never be exactly like it was...but just the result of another change.

Now, the only way we could possibly interfere with this change is to travel to a parallel universe. The theory of parallel universes states that there are multiple or endless numbers of universes parallel to our own. Each universe would almost be the same, differing in only a few aspects. While some of these universe are ENDING, some other are just BEGINNING. Hence, in one of these universe, earth is still in 1958 and in another 3005. Now lets say we travel to an earth whose year is 2004. What will happen then? Well, you could meet an alternate you. Or if you are able to change things..will the changes really effect you and the things from your universe or will it only effect the parallel universe you are at??

Now how would we travel to a parallel universe or better yet, How CAN we travel to a parallel universe? Well...first you have to have enough energy to create a singularity or black hole...Which will never ever happen. And even if it did...we would all die from getting sucked into it.

[Redux-shika boo]

I say time travel is possible. Going by the conventional thoughts of what time travel is though is the first mistake. Since time is a relative for any one indvidual, to break a part of a constant continum is impossible. Time travel would have to evolved not just returning to an older set of past events but would include all things arund in the enitre universe being altered contrayer to the "natural order" which I think is for living things or all things in general to get older or age and eventually wither away.

Anyway the reason I say it's possible is if you abadon the conventional belief that exist surrounding time travel it can then be done. All that is necessary is the right constitution of chemical and techonology on a global scale.

if any one single person could creat some sort of machine that lets loose gases that were say to cause temporal amnesia. During that time the one single operator could implant or change time(clocks etc) to manipulate everyone existing belief of what time it currently is. When this has been accomplished the single uneffective culprit would then have to find an effective means of doing this himself. However, before hand there would have to be a message left by himself to himself that he has traveled in time.

Hence if you have no memeory of an event however there is a record that you did it nd that it was an event of the past that was supposed to have been unalterable you will be left along with others who undergo said type of plan a belief that you did in fact travel to an area of the time line. Thereby effectively acheving time travel.

[Heldensheld]

I would like to change history

[Jedi Mind Tricks]

I was watching something on the discovery channel a while back, they said time travel was possible but it would be nearly impossible to do, due to the dimensions of the device.

[siliconrex]

If u want to travel through time, go through a black hole. Sure, you'll be streched mad long, but u can enjoy the future for like 15 seconds in really fast fast foward b4 u die.

[Heldensheld]

Some sort of machine has been created. If you switch the machine on, the machine will start collecting data of the surroundings. If the machine is left on for a few days, the operate might be able to teleport back in time. But if he does, that will cause problems.

[The 21st Hokage]

If I could travel back and forward in time to any three Era's it would be the following.

The Feudal Era - This is an era in time that has always interested me quite a lot for obvious reasons plus I would change history so that I would be a shogun myself who would probally amass the greatest army ever.

The Present - A Couple Of Years. -I would have knowledge of the future and thus becoming a prophet who would have earned the trust and respect of the people around him thus making world domination a hop skip and a jump away.

The End Of Time - Just to see how far has human technology and human evolution has advanced to be honest plus since technically since it's the end of time I can re-create everything from absolutely nothing.

Thinking about all of that I think it's better off if time travel dosent exist too many people would use it for their own personal goals hell I know I would.

[Q]

Human evolution has stopped. Actually, it is currently moving in reverse... because unfavorable mutations, instead of being eliminated through natural selection, are being corrected by technology and thus allowed to spread through the population.

[Cholisose]

You know... let's say some day in the future I build a time machine, after years and years of intense study and work. Wouldn't I go back into the past and save me all the trouble of building it? LOL. Because of that, I know I'll never build a time machine, since if I do build one, I'd already have it made.

Multiple worlds is a theory formed from quantum mechanics. It doesn't explain anything really.

Human evolution has stopped. Actually, it is currently moving in reverse... because unfavorable mutations, instead of being eliminated through natural selection, are being corrected by technology and thus allowed to spread through the population.
That's still an evolution, even if artifical. Maybe we'll start engineering humans and that'd be evolution too. Evolution =/= natural selection.

@Sabaku no Ira
If you are talking about the tears in the fabric of the universe, then that goes with my parallel universe theory. The tear in the fabric of the universe can be associated with a black hole. Now we know that a black hole sucks everything into it, but we dont know where it leads. We can theorize that it leads to a parallel universe like our own...and therefore that leads back to earlier post where I stated that even if we did make a change in that universe, will it make an effect unto our own?

Or if you're talking about the wrinkle in the fabric of the universe, then the space-time continuuan you're referring to deals with the "speed of change." We would be able to travel faster and teleport within an instant but...to be able to travel faster than the speed of light and how that correlates with time travel is not a concept I'm too familiar with. So maybe you can explain and clarify your take on this possibility. I would love to hear your point of view.

Ok, a brief (and basic) explanation of relativity effect: when an object is moving, time slows down, its length decreases and its mass increases. This has been proven many times by experiments similar to this:
You have two identical atomic clocks, both of them initially synchronized so that they will start off with the same time. One you put down on the ground, while another you put inside a supersonic jet that is going to travel in a straight line at supersonic. After a trip, it has been found that the two clocks will end up showing different time, with the one that has been on the jet a couple microseconds slower than the one on the ground.

And hence this is why relativity forbids faster-than-light travel. When you accelerate to the speed of light, your mass becomes infinite, your length becomes zero, and your time stops, all of which are impossible results.

Hmm...so what is your point? I already told you that time travel is not possible. and you just confirm that by saying we can't travel faster than the speed of light.

What I'm saying is that time isn't an illusion perceived by the brain. It certainly does exist and it effects how matter interacts with each other.

According to the Einstein's Relativity, it IS possible to travel through time: but only to the future. Say you're on a spaceship and you launch. You travelled near the speed of light for a year or two. When you return to earth you found that 10 years has passed. Woohoo, congradulations, you've gone into the future. But you can't travel back....

[lekki]

You're right, there is no proof you can travel back in time but apparently if you go into space and travel really fast, when you come back, everyone will be biologically older than you.

But if I could time travel, I'd go back and get a whole bunch of dinosaurs and their eggs.
Then I'd breed them out in deserts and jungles and shit and then just release and not tell anyone about it.

Imagine being stuck in a traffic jam out in Florida and some dude cuts you off in his Porsche convertible, all of a sudden a freakin' T-rex runs up to the dude's car and pulls him out. It would be cool and scary at the same time.

[Kakashi_Love]

techinically, because of the speed one is travelling...the rate of change for one thing can be moving faster than the rate for another thing. hence I say, time is but a rate of change. :kukuku

[wolfman_120]

Time travel may never become real but I bet a hell of a lot of people (including me) wish it will be

[abz_]

traveling to the future is based around the theory of relativity. where if you slow time for yourself when you come back to normal time everything will be older than you. as time went slow for you relative to normal time. thus you will have "traveled to the future"

but to go back in time, that is different, can you exsist in the past? as the time machine was never made in the past therefore if you were to exit say in 1940 when the time machine was made in 2005, would you exist? because there was no time machine back then.

i don't want to say too much on time travel as i am not an expert on quantum theoretics, but the actually travel in time, we must first understand them. to travel back in time we must find new laws of physic that support the theorems

(sorry for any poor spelling)

I think Time Travel is extremely dangerous purely for the things we could discover.

We could go back to the jesus days and fidn otu he was just a crackpot with a lot of charisma, or that actually....he DIDNT rise from the dead, they just moved the body.

Things like that would cause chaos when they were announced in the 'present'

[The 21st Hokage]

You do realize that if you did that, I'd have to come and kick your ass?

You would seriously expect people to believe Jesus is crazy? And not only that, the rest of the world wouldnt believe it, since you're a stranger to them, with no proof other than you went back in time. Things like the world will freeze over in 50 years might be a little more believeable, since tv showed a program that says were in a warm period before an ice age.

[Saitenzoji]

If someone were to go back in time and discover that Jesus was crazy...then if they had built a time machine, then surely they'd have taken something with them to accurately record the events that they witness. (I.E. a tape recorder.) And besides, if people found out Jesus was just some crazy guy, then the future will most likely change; there will be no Christian religion, and everyone would probably end up killing each other because they have nothing to believe in.

Anyway, back to the actual subject of time travel...With some of the past posts that I read, I think that they state accurate reasons, using Einstein's theories, that suggest we can travel to the future, but not the past. That is quite a valid statement, but the question is, will we ever have the technology to do such a thing? And if we do travel at amazing speeds in space, will we be able to survive? Can our bodies handle the shear velocity...can the space ship handle it?
In any case, all we can do is wait, and see if we ever acquire any such technology that can allow us to do any sort of time traveling. While we're at it, we should also try to find a bridge into parallel dimensions. >_>

You know all of this time travel conversation is intriguing. But you do have to think while "Persay if someone made a time machine through persay lot's of money and human resources" and we all can travel to the future like Saitenzoji said using Einstein's theories and not to the past can someone explain this to me. How in the hell will you be able to return to the "Present" since technically that would be the "Past" to you because your in the "Future."

21st Hokage You just created a Time Paradox.

Oh yeah I written an hand theory on Dimensional Travel a while back but it's deemed "Unstable" Hence someone telling me that my theory could either forge a wormhole for universal travel or it would be the end of existence period thus causing a super nova the size of the big dippers ass. Anyways if you would like to see it I can always PM it to anyone.

[U_zu_ma_ki_Naruto]

possibly off topic, but there is the theory of the existence of a multiverse where every possiblility of a current action that a person does and whatever is turned into a reality in another universe within the multiverse... i'd really like to see that happen :D haha
Not sure if it's true or not...but knowledge is infinite :)

[Scorpio3.14]

Actually, using Einsteins theory of relativity and special relativity, it is possible to travel back in time. Einstein predicts that space and time can both be warped by extreme gravatational fields. If time space were to be warped to a point where it looped back on itself, it can be possible to travel backwards in time. The question is if a human can survive the journy lol

[Heldensheld]

As I type, time flies by and it can't be taken back.

[Smooth Jazz]

Under the theory of relativity I can see travelling into the future, but I also like the theory of the multiverse where there are an infinite number of universes. Like imagine there was a universe for every second since the beginning of time, and instead of a time machine you build a demension travelling machine and you go to a demension that is actually the same just a set number of years or days or decades in the past?

Thats just my own crazy thoughts...

[Majinkiller90]

i totally agree with you i think the only way to travle is if there
