Is time travel possible

[wii_fiend]

Do you think it is possible to go back and grove with george washington or do u think time is a "force" that can't or shouldn't be meddeled with?

[Edjarosu]

If time travel was ever going to be possible, then the history books would be filled with passages about how time travelers went back and spread technology out all over the ages.

So no. Time travel will never be possible, ever.

[FollowMeAround]

i'm with edjarosu. if time travel were possible we would have heard about it a loooong time ago.

[MalikHalo]

Good sirs, might I refer to a short story by Ray Bradbury entitled "A Sound of Thunder" to combat your argument?

[LordTyroxx]

I was talking about this topic with my friend and we were both debating our own theories. It lasted about all day. If we can only get him on here... His name is CGamer.

(WARNING: Ranting ahead)

We were discussing time travel and the flow of time. (if it was a straight line or curved) I then thought of something; what if time was ever-created and ever-destroyed? My time chart was simply this: There is no time but the present, but there are infinitely many presents in other dimensions. My Time chart is a circle but it doesn't flow around the circle. Every point in this circle of time is another parallel world to ours and black holes and such could possibly connect them. That is why we never hear about time travel. When a person is done traveling through the dimensions the world they go to could be similar to the one we live on now. Every point on this "Time Circle" was created at the same time and moves at the same speed, but they are of every individual's choices. (ex. In another parallel world, this rant might be smaller but still similar)

This theory would make time travel impossible but dimensional travel possible. Everything in our past has vanished and everything in our future is not yet written. But every future that is possible is going to be in another dimension, which makes infinitely many dimensions.

Sorry for complex crap. I might draw a diagram, but for now I am done ranting.

(oops...this is what happens when I get ideas all of a sudden)

Hmm...I just thought about a cluster instead of a circle. In this, you can time travel in 1000 year intervals. Why 1000 years?

At the end of the 1,000 years, Satan is loosed, defeated again, and cast into the lake of Fire (Revelation 20:7-10). Christ then judges all unbelievers (Revelation 20:10-15). Then a new heaven and new earth are created. This is referred to as the eternal state, where there will be no more sin, sorrow, or death. Also, the New Jerusalem comes down from heaven (Revelation 21:1-22).

D-0 is God.
Some time in the future, maybe even when D-4574859 is created, Satan will start to destroy D-1 and the saved will join Heaven. (the bluish-purple background?) the rest will go to the horrid green text.

This isn't meant to offend anyone so please don't take it that way. Just saying what I believe in.

[el_sean]

If Back to the Future taught us anything, it was that time travel really can screw up the past.

No, in all seriousness, time travel is impossible. If there was such a thing as time travel, then there would be no such thing as time. The past, the future, the present would be the same because the technology of the future would be in the present and past.

That might be a bit confusing, but I hope you get my point.

[Nintend()\/\/|\|312]

I'm not quite sure but I am pretty sure it is impossible. Even without getting into the physics, you could never go back in time to stop anything from happening because if you did you would end up eliminating the reason for you to travel back in time to change whatever you changed. Even if you took precautions things would still no doubt get really screwy. Actually, I'm not quite sure about that. An interesting case for time travel came up in the third Harry Potter movie. As long as you assume all of your actions as you trevel back in time are pre-determined, things might go quite well. I still don't know though. I think I came up for a reason why it still wouldn't work but I forget it.

[Bjorna]

If time travel was ever going to be possible, then the history books would be filled with passages about how time travelers went back and spread technology out all over the ages.

No you're wrong, let me give you an exmple.

If a guy, lets call him John, live in the year 2153, when timetravels are possible, suddenly decides to check up on his relatives from the past. The history books will tell him that his great great grandfather lived in the year 2007, and met his love of his life then. The books will tell him that he lived a happy life and got lots of children (one of them johns great grandfather). Now John decides to go back in time and kill his father. According to scientists one of the following things will happen.

1. He travels back and shoot his father in the head before he meet his upcoming wife. The father die and John will cease to exsist.

2. He travels back, shoot his father in the head, but something, a 'miracle' makes the father duck and then manages to live on and be Johns great great grandfather.

3. He travels back, kills his father, travels back to the future and live on, since he is allready born.

If nr 1 happpen the books which told John about the books will say that he died after getting shot in the head. but this will be an alternativ reality:

Code: Select all

-----------------------------------------------------------
      2007/\                                          2153/
             \
              \____________________________________________
                                   alternative future 2153/

the --- line is the normal timeperiod, if no one ever touched the past, changed it.
the ____ line is the alternative future

In the --future the books are written about what really happened.
In the __ future the books tell people about the death of Johns great great grandfather.

As you can see the reason why the books are not filled with people who have travelled through time, is that the time machines have not been invented yet, and we're still on the ---- time line.

If nr 2 happens. the time line will look like this:

Code: Select all

------------------------------------------------------------
2007/                                               2153/

Nothing special since the past wasn't changed

If nr 2 happens the time line will also look like this:

Code: Select all

------------------------------------------------------------
2007/                                               2153/

Nothing special here either.

Anyway if you think about it, nr 1 seems more logical. But if that's only if timetravels are possible. The question about if it is possible, is a question I can't answer. All I know is that they wont be able to do anything without the flux capacitor

[wii_fiend]

my personal opinion is it is possible because of the whole "traveling at the speed of light slows time and eventually stops it" this kinda makes me wonder if you could travel even faster could that make time start to go backwards. (which of course brings up the whole thing if traveling at the speed of light is even possible. Then if it is, is it possible to travel faster)
I kinda agree with the "theory" that if time travel is possible then we would already know about it, but then maybe we're in an alternate time line. Whoa this is confusing, i'm goin to play some majora's mask to clear some things up. LOL

[NintendoWiiForever]

yeah so if you traveld near the speed of light and shot a bullet would it time travel to teh past

[Bjorna]

No.

When you travel in near the speed of light, the time only goes slower, you can't travel backwards in time. Let me give you an example to proove my point:

If two people each have their own space ship. and one travels at the speed of light (1) , and the other does not (2).
For nr 1 time will go very slow, but for nr 2 the time will go as fast as usual. this means that when one minute have gone for the first person, perhaps an hour have have gone for the second person. so you will be able to "travel into the future" but not back again. a one way ticket if you like.

[NintendoWiiForever]

oh alright makes sense (as far as making sense of timetravel can go)

my theory is (like many others) that if timetravel did some time exist in the future we would know about it today because they would have come back and be in history books or come tell us them selves or something lik that. and if they were afraid that it might change the future then what is the point of using it?!

i guess i don't think time travel exists but i would like too.
but just because something seems impossible doesn't mean it is.

trying to fly seemed absolutely insane and impossible...but once we found out how it became easy...time travel may surprise us the same way...
"all we had to do was eat banana pudding while thinking of a different time ?!"

Well, Bjorna already put that one to rest. I hadn't thought of it the way he had.

And what's the point if we can't change stuff? Observing the past is an absolutely enchanting prospect to some people, myself included. Even if it's a past that we can't change.

[LordTyroxx]

Bjorna, for some reason that seems like you stole from Back to the Future.

[Bjorna]

Bjorna, for some reason that seems like you stole from Back to the Future.

Hah yeah it might seem like that :p I didn't think of that before. I just read this article in this science magazine (illustrert vitenskap, or Illustrated science in english) about time travelling, so that's where I got it from

i actually heard of some guy that went on a radio station claiming to be from the future. he made all these crazy (back then) predictions and all them so far came true the only one that didn't (yet) was that the us would have another civil war. I can't really prove this because i can't really remember where i seen it.

[Dark Evil Emu]

I don't really think that we can know if time travel is possible, but here are my two beliefs on time travel:

First off, I don't think that the fact that no one has visited us from the future is a valid argument against time travel at all. Time travel would no doubt be restricted in the future, whether people were not allowed to come back at all or only with certain precautions. Also, maybe the timeline would split as mentioned before. We just don't know the nature of timetravel so we can't judge it by our past.

Secondly, I think this question comes down to whether or not time exists. This is a pretty widely debated topic. Some say time exists as most people percieve it. However, others say that time is just an illusion, and there is nothing but the present, so to speak. I think that if time does exist, there's got to be a way to travel through it. Maybe it wouldn't be possible to humans, but there must be some way, somewhere in the universe that it would be possible. And obviously, if time doesn't exist then there would be no time to travel through.

That's my two cents.

Well, that is what I was trying to get at with my long post. I believe that there is no time but the present but many different parallel worlds to ours. I guess no one read my post because it was too long.

I wrote down my "Theory" in my notebook (more in depth than my post) and I have people that think it might be possible. (then they said I should start a cult- I put my notebook away...)

[dbroad]

Time for us is a spatial dimension that we travel through in time. As time increases so does the universe, imagine a balloon with the universe painted on it now blow it up, the air you are blowing in represents time coming into the universe nw then this causes expansion however it also means that between different points in time the universe stretches to handle it, now using rough logic for higher dimensional travel, if you managed to travel through time by releasing air out of the balloon or by further blowing it up the universe will shift and as you are outside of times effects you won't meaning you get dropped into the void the universe is filling (where the air is in the balloon or outside of it.) As we exist in a 3d universe we would have a higher chance of finding the universe but still run the risk of the void-space which is of such a high dimension would mean death. So time-travel now has a terminus point, but is it possible? mass bends the universe thus meaning you could create a bubble of time by existing at the center of a large mass then by applying energy to your bubble it should move through time but in what direction, depends on the angle of the energy-wave you put in. While we can create small bubble and slow time down in labs we haven't yet got the technologyfor humans.
Also any time traveller from the future hitting at any point before time travel will be dismissed as a supernatural encounter as the human mind adapts to save itself from what appears to be impossible by making it an actually impossible event any traces would dissappear along side their time bubble when it collapses due to the energy required for time traveling taking up energy needed for the bubbles existance.

[NintendoWiiForever]

if we are going with what you said dbroad then time travel will happen on it's own in the future.
the theory is(my new one) that since the big bang the universe has been expanded and eventually it will get so big that it will start to shrink ( either a really quick implosion or gradually until it is as small as a single atom and creates another big bang.) if im understanding you correctly and the universe will eventually implode on it's self then we should see (or experience...but i guess will will not experience it because memories don't work backwards )
a natural timetravel.

does this mean that there was once no time? or at least until the big bang...or maybe this explosion/implosion timetravel has happened forever and there never was a beginning (beginnings are a human made idea)

also maybe this expansion of the universe is always the same which causes all time to happen the same way all over again and again.

whatever...what do you guys say?

[LordTyroxx]

We all have experienced time travel...

Now the physics behind the time travel have been revealed to us. Or are you forgetting about the messageboard time machine of utter chaos?

Natural time travel...never thought of it that way before... I think the baloon will pop eventually and we will all die.

But technically, what is De-ja-vu? It could be time travel and we don't even know it yet.

[NintendoWiiForever]

dejavu could just be coincidence or maybe it has some hidden meaning that we are all ignoring...who is to say?


....lol and on a side note my sig does mention that our digital selves have experienced time travel ...so far digital timetravel is possible lol.

im have trouble understand all of Einsteins stuff ...can some one help me?
every place on the internet makes it impossible to understand...i need to hear his theories in idiot.

black holes are often associated with time travel and i think those types of things are the key to it all.
in regular black holes intense gravity sucks matter and light (and what ever else) in and creates a point of singularity where time cannot exist and all matter is compressed into a singularity which is only being held together with the pure force of gravity. some say it can even compact matter until it is destroyed altogether.
they say if the black hole is spinning it creates the same singularity but instead of a single tiny point it is a ring...a ring with no time and incredible density and compression and if you where to travel though the ring you would travel though time and space.

another possibility is spinning worm holes. when two black holes connect they create a worm hole. if these black holes connect though space it could be possible it travel into one and come out the other but 1000years or so in the past or future..even if it only seemed like 1 HR to you.

it is also said they can connect though time. if these rings in a spinning black hole can transport you though time then they themselves might be connected to each other though time/

i didn't make that up as my own theory by the way...im not that smart.
sorry if i worded it wrong so it didn't make sense

maybe time travel is a natural process and we are all just idiots who create fixed ideas on how time flows and that there is always a beginning and an end to everything.

[LordTyroxx]

The problem about wormholes... It is like your whole body trying to squeeze through a wedding ring at a thousand miles an hour... it just isn't possible. And that isn't including how your body will be affected with the black hole's g-forces.

If a human tried to go through a black hole, I would think they would pop from the pressure and bloody parts of them will fly to the black hole.

Has anyone here seen the movie Time Splitters? It was about a watch that sped up the molecules in the wearer's body so much that they felt like time was stopped.

I read your post actually. What you were saying reminded me of the multi-universe theory. Is that kind of what you were going for?

[NintendoWiiForever]

yeah time is another human made concept it may or may not exist and we have no way of telling ...just like beginnings and ends(im so redundant)
