Time travel... Is it possible?

[007vader]

Personally I don't think it's possible. I still think it's the funnest mind bending thing to talk about in the world though.

Also MY FIRST THREAD STARTED HERE WOO HOO. :dance::dance::dance::dance::shifty::dance::dance:

[Kitmitsu]

Well as Steven Hawking says, no one from the future traveling back in time to contact us pretty much proves that time travel is never invented, however it could be that they never visited our time. Some believe it's possible and some believe only the present exists. I don't know much about the subject so I'll post my real opinion after I do some reading :P.

[Rekhyt]

Time travel is possible. It's just that to do it and have a serious effect revolves around sitting next to or inside a black hole. So even if you were able to travel back in time you'd be dead so fast you wouldn't be able to use the knowledge. That and your trapped in a black hole so you'll see the universe flash past you from the perspective of the black hole. All you'd see was the void of space.

About the Stephen Hawking thing and visiting the past. It is possible that they have but we don't know because they changed an event which caused all of human history to change. That however is flawed by the fact that if they changed something, their time line would cease to exist and if they never existed they could never have made the change in the first place.

Basically it is possible but it's so damn confusing and intangible that it will probably never happen and if it did we wouldn't know that it did.

[Hitoshura]

No, there never will be time travel EVER!!!

Theres no point arguing this cause its stupid.

[XxFeaRLeSsxX]

Time travel? Maybe, but by the time it's invented, we're already dead....most likely :blink:

[Unknown Kaze]

time travel is like moving at the speed of light, theres a possibility of it happening, but at the moment, it very easy to disprove either theory...

[Devious]

Time travel is easily possible, traveling BACK in time is not.

What has already happened has already happened and it's impossible to change something that no longer exists (the past).

[Pixel]

I do not think Time travel will ever happen. If you do have to move at the speed of light to time travel. We are VERY far from being able to because you would have to create some material that could withstand the speed of light.

Plus, your body would most likely be ripped to tiny particles first like in a black hole so..........

It will never Happen.

Btw, I did not read up on this, this is just theories and my opinion, so if I am wrong about the black hole thing, oh well.

[Hitoshura]

Theres no certainty on what the future will be, so how can this be possible ?

[Devious]

Theres no certainty on what the future will be, so how can this be possible ?
It's only possible if you believe in destiny. Perhaps everything is already predetermined.

Besides, you can easily travel forward in time simply by moving very very fast for a long time.

[Pixel]

That made me think of something......Is time even real? The human race created it as a way to tells the beginning & end of a day. So........is Time really just a tool for the human race?:blink:

[007vader]

Time travel is easily possible, traveling BACK in time is not.

What has already happened has already happened and it's impossible to change something that no longer exists (the past).

Very true It would be possible to go into the future but getting back would be impossible.. maybe. One thing I do know is that going back in time to change something is either impossible or would be really stupid. Due to the fact that you would go back (say to stop an assassination) you would go back and stop the person from dying.
Then they didn't die, which mens that you never would have gone back to stop them from dying. Which means you WOULD go back to save the person then repeat repeat repeat on and on for all "time". Or that may create a time paradox so that time unravels then we're ALL really screwed.
So (important lesson) if you get the opportunity to go back in time, DON'T CHANGE ANYTHING!!! or else you may either get stuck in an infinite time loop or you'll destroy the universe. No pressure. ^_^

Then here's one. When is the present :shifty:? Are we in the present or are we really in the past, and if we are in the present what happens if someone goes in the past then are they actually in the present or are they in the past?:shifty: What defines the "present"?

Just venture a well thought out guess. Heheheee.

[Dream Machine]

I remember reading once that any time machine would be able to only go back in time and only to go back as far as when it was created. For example if I made a time machine in 2008, in 2010 I could go back to 2008, but no further back. Explains why theres no visitors from the future.

That's a very good theory. It makes a lot of sense, since time machines travelling back in time don't actualy move in terms of space. But still, how can there be a set time for when the machine was created? Like the moment the parts were put together, or when the machine itself started to function? Or maybe when the idea was actually conceived? It's impossible to say exactly when the machine was created. And technically, if that were true, then the moment the machine was conceived, another one would spontaneously appear from the future, in the EXACT SAME PLACE AS THE FIRST MACHINE and space would collapse, since there are two masses of matter existing at the same place on the same plane at the same time. And that would really suck. Unless, the universe, seeking to save itself, created a second plane and placed the machine there. So it's like on a plane we can't see, but it still exists.

[Dream Machine]

Hmm well I suppose the machine being able to physically exist in the same place at the same time depends on if you buy into the many-worlds theory. As in every possibility that could have and could happen did and does. If that were the case the machine could exist in one or more of our possible futures? Then it could exist as potential?

Wait how would that work? Do you mean like a teleporter that has to have a receiver to go to and in this case it would be the receiver?

[Dream Machine]

No I mean to use the time machine it has to exist in all time you want to travel to, you can't send it back. Only keep it in existence and use it in the times in which it exists. this is assuming the past isn't just potential and really exists.

[Slim__Cognito]

if a time machine was made ..having the power to rip the fabric of time as we know it anyone who first thought of being able time travel would instantly have the machine as they thought of building it . also wouldnt time travel be just infinite knowledge rather that a machine , if you knew all that would happen in the future i think you could be 'in' every time. saying though that are bodies are just looking glasses on the universe while our 'being' is omnipresent and we are just bound to the body in a certain time . but if we could sever the tie between our current body and take another from the future or past. maybe using the other unused percentage of our brains we could do that

Or, according to Stephen Kings, we could gain psionic powers.

But yeah, I didn't get most of that stuff, but I think that would only work if you were like, a spiritual kind of person. I'm not. =/

WOW:blink:.....

That last part's a new one.

This is why I like to talk to people about this stuff. I like to hear new opinions on it.

Ummm.... wait, you mean like the time machine becomes a bubble that takes you to any place it has existed. Or kind of like a place that is removed from or is separate from time as soon as it comes into existence?

[Wyvern]

Maybe I'll go back in time and actually turn out to be Jesus. People talk about "Nobody appears to have travelled back in time and changed history", but if time travel did exist we can assume very few people had access to it and only for a certain amount of time did it exist - and those few people went back in time to be religious leaders, generals, help out with wars and so on, not realising that it had already happened - but then, they were always going to do the time travelling if they were back in time, no matter what, so it makes little difference.

Anyway, I don't think time travel is possible. Even if we could travel faster than the speed of light, and many times faster, where would we go? Plus, if you went back a microsecond, you'd be in a slightly different position from yourself/your ship was at that time before, so you'd kind of explode and merge with the other space ship, and be inside eachother, which would mean that that space ship never could have reached the speed of light in the first place, meaning the already time travelled ship could not exist, ugh. So, possibly any time travel will create a time paradox like that?

[007vader]

So, possibly any time travel will create a time paradox like that?
Pretty much. A few exceptions but not many.

[Demon Eyes]

I think the problem here is... time doesn't exist!:blink:

[Halfmetal]

1)Change causes time.
2) Therefore, If change exists, then so does time.
3) Change exists.
4) Therefore, time exists.
:)

[Demon Eyes]

No change does'nt exist either, it's just how you describe something. Humans invented the concept of time, so it's only known to us.

[Halfmetal]

How can you doubt change? If there wasn't change then we would be at a complete stand still forever. How does the sun rise? Through change. We can't invent laws of nature. Did Newton invent gravity? No. He discovered it. Gravity occured and hit him on the head with an apple before he completey realised it.

[Demon Eyes]

Well the sun rises because we are spinning. I guess it doesn't actually rise, as in go up, it just appears that way. You need to sharpen your definition of exist. Change is a description. Time is a measurement, the same as an inch or a foot. An inch doesn't exist, it is merely a description. Time = a measurement OF existence, if you will.

[Rekhyt]

Time is a measurement, the same as an inch or a foot. An inch doesn't exist, it is merely a description. Time = a measurement OF existence, if you will.

It doesn’t matter that time is a measurement. The topic is on whether you can travel through time. You can travel a distance despite the fact that it’s a measurement so why should this stop you moving through time?

[Demon Eyes]

You can travel from one place to another and measure them with feet, because both your starting point and your ending point exist through all points in time. Past and Future do not exist.

[chuk bur]

ive always wondred if it was possible to break the laws of time. but the thing is if we did figure it out what be the consequences? some say itd rip a hole in time and space itself and all this other stuff. wondering what would happen is what we could really talk about. if we do get tht way back in time how would we deal with the consequences we talk about? are these consequences true?

[Mirrain]

Possible but will never happen during our lifetimes.

I didn't read through the entire topic but it has nothing to do with black holes, they are just the aftermath of stars imploding on themselves that become the same mass in a tiny area.

From what I understand (and can wrap my head around) even if you were to travel through a wormhole which is hypothetically possible, you would arrive at the destination across the galaxy at the same time as leaving, thus time stops where it would usually take you X amount of time to get there.

Regardless even IF it were possible, I doubt you'd ever see anyone being able to use it. Human beings are too reckless to use something like that without catastrophic consequences.

[Halfmetal]

You're pretty much repeating your point there, and I think there's been a bit of misunderstanding. By change I am talking about cause and effect.
Like I said if there was no change we would be at a complete standstill. Ice melting. That's change and we use theories such as laws of nature to describe it.

Just becuase it's used to describe something that doesn't mean it's not there. Time is not a measurement. We measure time. You can't measure time with time. There are many theories regarding time.
http://en.wikipedia.org/wiki/Time

By the way. Are you a sceptic?

[Demon Eyes]

Did you even read that link on time? It states time is a measurement at least 20 times. You have to understand that time DOESN'T EXIST. Show me proof that time is an actual thing.

http://www.dontdosocks.co.uk/images/Shocking%20Alarm%20Clock.jpg

I caught time - see it does exist! See see.

But seriously I agree with you, time is a measurement, I don't think you can travel in on or any other way/ In physics, time is described as a dimension much like length, width, and height. When you travel from your house to the grocery store, you’re traveling through a direction in space, making headway in all the spatial dimensions—length, width and height.

[Cloud Strife]

What is the point of time travelling anyway? Haven't you guys seen the movie Time Machine? Even though we travel through Future and Past we can't change anything. To put it an easy way it's like this. You fall into a puddle, and you go back in time to not to fall into the puddle, but your gonna fall in there anyway. I hope you guys get that. So Basically saying that Time Travelling isn't possible. Unless You are Hiro Nakamura. (The GUy From Heroes Who Can Time Travel)

[Terros]

Short answer: Is time travel possible?

Theoretically and scientifically yes, however at this current time we do not have anything that can produce the energy required to pull it off.

[Yurian]

No. Time travel is not possible. Time is still going on while traveling from one place to another.

Taking fate and predestiny out of the picture, Dimensional Travel beyond our current dimensions may be possible if other dimensions exist.

Think of a dot (a representation of a dimension) that represents a single moment in time. It is impossible to exactly state what time that dot exists; is October 1, 5:56 pm and 26 seconds October 1, 5:56 pm and 26.1 seconds, or 26.01 seconds, etc.?

Now imagine an infinite number of other dots that connect to this original dot. Those other dots are representations of other dimensions, while those connections to that original dot are pathways upon which events may occur. Of course, more dots exist upon those pathways; consequently, there is an infinite amount of possible actions occuring from just that one dot (and consequently from other dots).

As an example: After I get up from my computer, I can do my homework, go outside, close the curtains, draw, get some food, drive my car, etc. There are an infinite number of possible actions within a given time slot.

Dimensional travel, therefore, still includes the premise of time because time is always ongoing. However, imagine the possibility of traveling to another dot that seemingly ocurred in the past. Although it may seem like it's in the past, in fact it is just another dimension - a complete world that is different from ours. What if for every possible moment of time that goes on in our lives, an infinite number of dimensions are created?

I'm not even sure if I'm explaining this clearly enough to convey the idea.

[Demon Eyes]

Only forward in time though, not backwards. And it's not time travel as people imagine it, it's a time dilation. You will experience days or years in a matter of minutes. But of course you must be traveling near the speed of light.;)

Good explanation Yurian!:thumbsup:

[Halfmetal]

Eh? I see it says 'time itself is something that can be measured'. I don't know what you're talking about.

Just answer me this. If time is a measurement, what's it measuring?

[Cloud Strife]

No. Time travel is not possible. Time is still going on while traveling from one place to another.

See!!! Even Yurian says it for himself. It is not Possible.

[Demon Eyes]

Eh? I see it says 'time itself is something that can be measured'. I don't know what you're talking about.

Just answer me this. If time is a measurement, what's it measuring?

Existence.

[Halfmetal]

Er, what? What do you mean?

[Rophe]

No no no, time is like 'distance' it is measured in seconds and such. And im travelling time right now, at the amazing speed of one second per second! Time is just like distance except we can only move in one direction and at one speed, unless you got light speed where everything gets funky like Abe Lincoln on crack.

[Halfmetal]

Abe Lincholn on crack. That's an interesting image.

[Cloud Strife]

No shit it is measuring distance. What made you put in Existence?

[Demon Eyes]

How are you not seeing this?! Time measures existence. Every second that passes is one second of existence. Let's say if before the universe there was nothing, there was no time, as there would be nothing to measure. I think you guys are lookin at time as a 24 hour cycle. That's just a different way of using it. If you see time for what it is, it's never ending, it doesn't reset at midnight, it continues on forever.

[Cloud Strife]

If time goes on forever how can I measure existence?? All measures come up with an end.

[Demon Eyes]

If time goes on forever how can I measure existence?? All measures come up with an end.

Well I've been alive for 19 years and so many months and 1.. 2.. 3 seconds. I just measured my life with the amount of time I've been in existence. You see, here, I'll say it again. I exist, but time does not. There will be an end of time, once the universe collapses in on itself. Time is the measurement from the beginning of existence to the end. It's a simple concept to grasp, I'm done trying to explain it now though, either you get it, or you don't.

[Cloud Strife]

I do... I just don't understad the point of this topic.

[Rekhyt]

Ok getting back on topic then; if time is a "measurment of existance" (cough it makes absolutly no difference cough) why can't you move through time to another moement of existance.

[Demon Eyes]

BECAUSE YOU TRYING TO MOVE THROUGH TIME, WHICH DOES NOT EXIST! If a cookie doesn't exist you can't eat it.

[Cloud Strife]

Demon EYes is right. Time does not exist.

I think it's mostly the same as the fact I told you guys about that puddle. And there was this other guy who told some theory but I forgot who it was.

[Halfmetal]

Demon Eyes has a very interesting idea, but i think that (assuming time is a measurement) then time is measuring change. But honestly, I thibnk that time xists, and it's not a measurment because change causes time (and change is a verb by the way <_<)

BECAUSE YOU TRYING TO MOVE THROUGH TIME, WHICH DOES NOT EXIST! If a cookie doesn't exist you can't eat it.

I think he means moving through whatever time is measuring. Anyway, Steven Hawkins believes in time travel which just shows that opnions can differ on this subject. None of us here are scientists or anything so none of us can really say this is right and this is wrong.

[Demon Eyes]

Well I believe in time travel, but it's only forward in time. Does Steven Hawkings believe in traveling into the past, or the future only? There are scientific explanations to traveling forward in time. And the past doesn't exist either, so how could you travel into it?

[Halfmetal]

How the hell should I know? All I know is that he said it's possible on that crapy Richard & Judy show.

Here's video which should be enlightening:
http://www.youtube.com/watch?v=W3uOsZduP0Q

[Demon Eyes]

How the hell should I know?

You should know if your gonna bring it up.

[Cloud Strife]

uhhh.. Wait a minute.. Instead of being stuck arguing about measuring Existence... let's figure how we travel that fast.. I mean if we are teleporting through time.. That means we would have to go Faster than time which is almost close to Inifinite Speed. So.. Yeah I guess.

[Rophe]

It is hypothetically possible but we will never be able to do it.

[Halfmetal]

You should know if your gonna bring it up.

I showed you the bloody video. STOP COMPLAINING! :nag:

[Demon Eyes]

I showed you the bloody video. STOP COMPLAINING! :nag:

Are you serious...?

Einstein believed if you traveled faster than the speed of light, you would be in a timeless zone.

[Halfmetal]

A timeless zone? And how is that possible when time doesn't exist.

Look, I told you opinions can differ. Anyways, Steven Hawkins would pwn Einstein anyday.

[Demon Eyes]

I'm done trying to prove time travel is impossible, lets hear you believers try and prove it is possible.

[Halfmetal]

I don't think you have to prove it's possible to believe it. You just have to prove it's possible to get others to believe it. I for one don't believe it, but hey, I could be wrong. Who knows?!?!

[Demon Eyes]

I don't think you have to prove it's possible to believe it. You just have to prove it's possible to get others to believe it. I for one don't believe it, but hey, I could be wrong. Who knows?!?!

Well you sure sound like a Christian.

[Halfmetal]

Well you sure sound like a Christian.

:huh:

???

You know I'm a muslim, right?

[Yurian]

According to dictionary.com:

time: the system of those sequential relations that any event has to any other, as past, present, or future; indefinite and continuous duration regarded as that in which events succeed one another.

Basically, it means that time is the system of relations between actions/events. Therefore, if there are actions/events, then time must exist. If there is time, then actions/events must exist. It's proof of the difference between three dimensional existence of matter and the four dimensional movement of matter.

I don't know if that sounds clear.

[Sundance Kid]

Halfmetal: Coolio your'e a muslim?? Haven't met a muslim since my friend left *sad face*

Yurian: Yeah I think it makes sense, it's like movement of time is movement of life??? I understand what you mean I just have a weird way with words. lol

[Demon Eyes]

:huh:

???

You know I'm a muslim, right?


Man I hate having to point out when I make a joke...

Time is real, but it doesn't actually exist as in made up of matter.

[Halfmetal]

Sorry, I don't get jokes easily. What was the joke?

[Yurian]

DE was sarcastically pointing out that your comment sounded religiously fundamental. I don't really think it was a joke; in fact, I believe is was not really appropriate to say something like that on this forum, much less at all.

Please direct further posts concerning this "joke" in a pm. This topic concerns "Time Travel", not "Religion".

[Sundance Kid]

Okay so IF time travel is possible, how many ppl responding to this thread would try to change events in time???
And if we/you did change events would it make any difference in how ppl are today??

[Yurian]

I have to say three points in response:

1) If time travel to the past were possible, how would we know? Our memories and our purpose in changing something would have been rewound. Indeed, they wouldn't even be there.

2) If time travel to the future (excluding the immediate future) were possible, then is it really time travel anymore? That future would now be the immediate future, and so the situation upon which we had planned to do something has already changed.

3) To answer the question while taking out the reactions from the previous two points, I would still come upon two duplicities, one for the past and one for the future:

If I were to consider jumping to a later future - for example - two years later because I want to circumscribe the college applications, two uncertainties would come up: 1) I could do this because it would be easy 2) I would be missing everything in between; the two years I have lost are years where I could have learned something from doing applications.

If I were to consider jumping to the past - for (a highly exaggerated) example - to change the fact that I went to my current school, two uncertainties would come up: 1) I could do this because my best friend went to a different school 2) I would be losing my current relationships with my friends at my current school; they possibly wouldn't even know who I am.

---

To conclude the above points, I still have to say that time travel is impossible. One is thinking human-positive/centered when he concludes that he can retain his memories and his physical composition when traveling to the past. In the end, we're still a myriad of atoms and molecules working in a larger system. Every action causes a reaction; every existence interacts within the system that is the universe. Fate and 'predestiny' cannot be circumscribed.

On the other hand, as I've said before, 'dimensional' - in lack of a better word - travel might be possible. We could travel to an alternate dimension that is very similar to our pasts, allowing us to retain our memories while changing that dimension's (our very similar 'past's') situations.

[Demon Eyes]

Yurian, regarding going forward in time. From what I understand if you were in a vessel and you traveled say 100,000mps in outer space for 1 month according to your watch, turned around and came back to earth 1 more month. You would have only aged 2 months, but here on Earth, it may have been 2 or more years. So you wouldn't have necessarily lost 2 years.

[Yurian]

That would be an aspect of physics, though, not of actual time traveling as conveyed by what we previously inferred time traveling to be.

If you don't mind, however, could you please explain the mathematics behind your explanation? It's been over a year since I've taken Physics class, much less any Science class.

[Halfmetal]

I haven't taken a physics class in 2 years so it's wrong to ask my opinion. By the way, does anyone here actually study this topic in physics or something, or are we just having brave stabs in the dark?

[Demon Eyes]

I couldn't give you the mathematics, I never took physics, just been teaching myself what little bits I know. I read about this in Einsteins work on Special Relativity. It basically states that time and distance are not fixed times, they can vary between observers. Like if a 12" ruler was flying past your face it would appear to you to be maybe only 10", when in reality it is still 12". I don't know how to write it in math, but I agree with it because I've observed situations like this before. But ya it's physics, which is just another theory in life.

[Halfmetal]

Lol, so we are having brave stabs in the dark. Well let's hope we all don't kill each other.

[Yurian]

It's not brave stabs in the dark. Always, if a person says something, it's because it's being influenced by a previous experience.

In my case, I'm speaking on what I consider to be logical.
