Time Travel

[Benjaman]

My take on Time Travel:

If in the future, at any time, any place, they figure out time travel. They go back in time, and randomly end up at some time/place. What if, they came in a form of transportation, like the DeLorean from Back to the Future. Now, what if, since they are so far into the future or whatever, that they have some kind of circular flying disks for transportation.

UFO's?

That's my explanation if anyone ever asks me if I believe in aliens. It makes sense. Some time traveler happens to transport into the open and someone sees him. UFO sighting. Makes sense, doesn't it?

/conspiracy

Now, I invite you to rant about your crazy scientific Time Travel theories.

[Grim]

What if we traveled back in time and killed are past self? What would happen?

[hzac]

The DeLorean is real.

[eVIL BOB]

Dude back to the future is real

[some n00b]

What if we traveled back in time and killed are past self? What would happen?

we would exist in the future, but not have any record of it.

[Savaril]

No. Its a paradox, there's no real logical answer aside from saying that we'd just die, and we'd be dead in the future.

[suszterpatt]

Suppose you go back in time to watch when John Lennon writes Let It Be. However, you discover that John Lennon doesn't have any inspiration, so you sing him Let It Be, he proceeds to write it, you go back to the future and everything's fine.


Now the question is: who came up with the song Let It Be? It wasn't John Lennon, because he learned it from you, and it wasn't you, because you heard it from records when you were growing up.

I have thought like that to. Because People see a UFO then its gone. Maybe a time machine? Probably not though.

[eVIL BOB]

What would we call someone who was (one time i went back in time and impregnated my mother who was pregnant with twins but i took one embryo back to my greatgrans time and impregnated my mothers mothers mother. Thus creating two twins who would then be transported back into my time (well 5 years before my time) then due to acts of incest gave birth to jimmy who would now be 5.)


Cause i sure as hell wouldnt call him uncle.

[Beefynick]

It is possible to time travel. Time does not pass at the same rate everywhere. In some nebulas time passes slower than on Earth. If you were to go to the Crab Nebula and stay there for a year. When you got back to Earth 5 years would have passed, but your body would have only aged for that one year that you were in the nebula. Thus technically you have time traveled.

[shinanigans]

Ben, if your theory is correct, then alien sightings could very well be humans who have evolved even further. Dundundun, conspiracy+.

[hipeechic]

Why go back? It only makes life more difficult.

[meTalmessiah]

If I went back in time and made the decision to start playing guitar at age 3, would I be a god right now? I'd totally do that.

[Benjaman]

So, you find it easier to believe that people in the future figured out time travel than believing there are other life forms in the universe which might have been able to travel here?

And plus if they figured out how to travel back in time, why not stop by and have a quick chat with us?

That Sir, is BULLSHIT.

Traveling at enormous speeds causes time to slow down RELATIVE to earth. The theory of relativity anyone? Thus traveling to and from the crab nebula would be in fact be what caused the slow ageing process.

What you are implying is that your memory does not get erased when you time travel. Possible, but can't be found out until you actually try.

[DamnDude]

Evil bob, enormous gravity also "slows" down time.. according to the same theory, because you know, gravity bends time and space n' shit.

Alien Abductions? I don't know. Plus: You wouldn't want to effect the future, would you?

[BAN ME PLEASE]

We made up the concept of time. I mean, do you think animals kept track of time? No. (I'm assuming) so when man came to earth (by adam and eve) they needed to call what they were "in" something. So they called it time.

We can't travel something we made up.

Black Holes being the only thing that could do this. No dust cloud is dense enough.

We decided to record time. Not decide "Hey guys, I'm bored. OH I KNOW. Let us go start having things actually happen." When I talk about Time Travel, I talk about the action, not the word.

If people could go back in time, then we would have tourists from the future.

Read the first post. I said that I think UFOs are tourists from the future. If that was supposed to be some pathetic stab at a joke, I suggest you get the hell out of my thread, good sir.

[DamnDude]

Ohh, I get where you are going with this, Im pretty tired so I didnt connect the dots, nevermind, we were on the same page all along.

[Grim]

If people could go back in time, then we would have tourists from the future.

Maybe we do. Also I think that the theory that is in Donnie Darko could be true. And if it is, then time travel is possible.

[Mr. Crow]

I believe that the universe is cyclical. That is, it will eventually stop expanding and will come back together in a 'Big Crunch,' resulting in a new Big Bang, which will in turn eventually come back together and repeat again and again in a never-ending cycle that has always happened and always will happen.

Going back in time is impossible, but going forward in time might be possible through the use of wormholes or who-know-what. Then, theoretically, you could go forward far enough into the future until you reached a Big Bang cycle that would play out exactly like the current universe, and stop somewhere in the 'past.'

[SlowCheetah]

Alien Abductions? I don't know. Plus: You wouldn't want to effect the future, would you?

I think you mean past. AND, if they don't want to affect the past then they did a pretty shitty job because we saw the space crafts. I mean if this is x number of years in the future, and these people have found out a way to travel through time I'm sure they would beable to keep themselves from getting spotted.

[Benjaman]

I think you mean past.

I meant future. If you go back to the past, and the Abductors(Time Travelers) go down for a nice meeting in the past and run over somebody, then that would effect the future. Or something along those lines.

[Seriodor]

I think that Time Parodoxes are impossible, because of the fact that if you decided to go back in time and kill yourself, your future self already a.)decided to try, and b.)failed obviously because you still exist. So something had to have happened that stopped you from succeeding.

[Pingu]

Going back in time is impossible, but going forward in time might be possible through the use of wormholes or who-know-what.

The problem I see with wormholes is that the escape velocity that you would need to reach to exit one of these things is greater then the speed of light. An enormous amount of energy is required to reach the speed of light and even then that speed is not high enough to escape the gravitational pull of the worm hole.

Also, what exactly is time?

Watch Donnie Darko.

Also, what exactly is time?

According to Dictionary.com:
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.

[Matterialize]

I think of it as dimension # 4. (http://www.tenthdimension.com/medialinks.php)

Going back in time is impossible\

You failed to provide an explanation there, Mr. DZ Mod. How exactly is traveling back in time impossible?

[Godly]

My theory is that everyone's theory's are un-provable and thus useless to discuss.

Time travel would fucking rock though.

[The Muffin Man]

My theory is that everyone's theory's are un-provable and thus useless to discuss.

Time travel would fucking rock though.

So by your "theory" all theorys are un provable and therefore irrelevant. So your theory, being unproveable is also irrelevant. Way to cancel out yoour post there bud.

This is just like time travel paradoxes they cancel themselves out.

[Matterialize]

I don't see why traveling back in time is impossible. Changing history is impossible. Example:

- In our timeline, Lincoln is assassinated.
- We know that even with time travel technology we'd be unable to save his life, because according to history nobody ever went back in time and saved his life.
- If his life was saved, according to history, it's impossible that a time traveler could've done it on purpose (why would someone travel back in time to save the life of someone who, according to their own history, was never assassinated in the first place?)
- If his life was saved, according to history, it's possible that a time traveler could've done it unintentionally.

I hope that made sense.

[Crabstick]

Time is irrelevant to the actions of people. Technically every time you take an international flight and cross time boundaries you have traveled in time, because when you arrive the time is not fluent from when you left. Also it would mean we time traveled every time clocks are adjusted for daylight savings. But time itself doesn't and cannot change.

Time travel is thus impossible.

[Ozz]

I totally get it now, we travel time through the UFO's, land on Roswell for our holliday, get cut open, but since we're from the future we don't take crap from anyone and we kick the ass of those scientists, then we go back and report to our demonic overlord in the future which isn't the future to us, and we start a time-war the likes of which has been never seen until Mel Gibson runs out of inspiration, so sayeth the Master Chief, ruler of Ozztopia, which is the best place to live in because we have cookies, which the paupers can't touch because I like them too much and frankly, I rule because of those cookies.

E=MC²

[barnesy111]

If people could go back in time, then we would have tourists from the future.
They took our jeeeorbs!
But seriously, this could prove to be potentially problematic what with all the changing the past and all, unless you believe one of those the-future-is-already-determined theories. No way of knowing really.

[Axidos]

Well, I don't have an opinion on time travel, exactly, just paradoxes. People are always going on about "If I went back in time and cut my past self's head off, the space-time continuum would implode!"

Thing is, it stands to reason that if the space-time continuum was destroyed at any point in time, every other point in time would simply collapse and we wouldn't be here. However, the space-time continuum seems to me to be quite intact, which leads me to believe this: If somebody ever manages to create a paradox, the space-time continuum will reboot itself and restore itself and continue as normal, only this time around, it will address the cause of the glitch: whoever caused the paradox will cease to exist.

This universe has limitless possibilities (yesterday I worked out how you can eat your own head). I'm not about to say time travel will never be invented, because how would I know? Considering the rate of evolution of Earth's technology in only the last few centuries, and the fact we have millions of years ahead of us, I wouldn't consider the possibilities of the future anything less than infinite beyond our vaguest comprehensions of the word.

Technically every time you take an international flight and cross time boundaries you have traveled in time, because when you arrive the time is not fluent from when you left.

Time travel is thus impossible.
Where's the reasoning? All you said was if I change the time on my clock I won't jump through the timeline. I don't see why that makes time travel impossible.
Ever heard of E=MC^2? That formula was conceived by a guy immeasurably smarter than you, and it directly contradicts what you said, and it actually has reason to back it up.

[spaj]

I never give Time Travel too much thought as I thoroughly believe that theorists need to wait until physicists can prove something, like string theory, to unify physics as a whole. Then we can worry about time travel being a feasible hypothesis.

Like string theory, though, I'd say it's almost impossible to prove time travel without using some sort of arbitrary method.

[Urser]

Time travel isn't real. If you go faster than light, you explode. Bada-bing bada-boom.

Science makes my head hurt. Aye aye aye. :wail:

[Crabstick]

Nope, what's that?

You failed to provide an explanation there, Mr. DZ Mod. How exactly is traveling back in time impossible?

People like to think of time as a river, that you can just swim against the current and go back. But it's not like that. Time is not tangible, it is not another dimension (in my opinion). Time is an idea. If you're knocked unconscious, and wake up an 'hour' later, has any time passed from your perspective? No. The fact that time slows when you move at high speeds shows that it is only a matter of perspective, not some sort of intangible stream. You can't go back in time because there is nothing to go back into, there is no 'past' upstream the river.

But that's just my opinion. Some other scientists believe that, for other reasons, you can not go back in time:

http://science.monstersandcritics.com/news/article_1032749.php/New_theory_says_quantum_theory_makes_travel_to_the _past_impossible

[Urser]

Exactly my thought Mr.Crow. (I think)

Time is a concept thought up by man. Just like ermm... Heaven. Yeah. Just because we thought it up doesn't make it real. (I'M NOT STARTING A RELIGIOUS DEBATE HERE).

[BadAnkle]

I never thought I'd say this, but I think you people smoke entirely too much marijuana.

[El Mojado]

I know time travel is not possible even if it is 3007. If time travel is possible then we would have many catastrophic things happening. Russia would be nuking us while were on the shitter. Not to mention the mass energy we must have inorder to reach those speeds to commence time travel.

But can it be that we can slow down/stop time, while we have space travel? Instead of spending 5 years floating in space trying to get to Mars, we have a machine that bends time for the ship and crew. Instead of getting there in 5 years we get there in 5 weeks.

Can it be possible?

I also think the idea that our lives are predestined and our choices have already been made is bullshit. There is absolutely zero supporting evidence and it doesn't even make sense.

[Matterialize]

Guh.


Time travel and changing history are two different things, and you people seem to be confusing the two. I thought I'd explained why changing the history is impossible.

Think about it. El Mojado, I'll use your example. Say Russia, in the year 3000 or whatever, decides to travel back in time to 2000 and nuke the fuck out of the States. That situation is already impossible because the year 2000 has come and gone, without any mass nuclear bombings. It's happened. If in the year 3000 Russia does decide to bomb the USA of 2000, we'd already have a memory of it happening. seven years ago.

- However -

What if, in 2008, a massive nuclear strike is suddenly launched at the United States? It's possible that this attack was initiated by a future Russia. Think about any major events in history. What if they were caused by time travelers from the future? What if JFK's assassin was a time traveler from the future? Who knows? Time travel isn't impossible by that logic, but changing history is, because we'd already have a memory of the changed event in history, and NO memory of the original historic event.

That being said, if time travel becomes possible in the future, any and all time travel to any point in time in the past has already happened.

[Stokesie17]

When people were talking about time travel and then killing yourself, this simply couldn't happen. Theres a set amount of matter in the universe, and if you went back in time and saw yourself, you'd be seeing your own matter. Obviously matter can't be in 2 places at once.

What about alternate time lines? Maybe it's possible to change history, but when you do, you branch out into a new alternate universe. Maybe that's why no time travelers from the future have have ever come to the past, because when they time travel they split off into another universe from ours.

[drunkchuck]

Suppose you go back in time to watch when John Lennon writes Let It Be. However, you discover that John Lennon doesn't have any inspiration, so you sing him Let It Be, he proceeds to write it, you go back to the future and everything's fine.


Now the question is: who came up with the song Let It Be? It wasn't John Lennon, because he learned it from you, and it wasn't you, because you heard it from records when you were growing up.

?????

I've got the answer; it was Paul McCartney.

The problem is if thats the case, then there will be no way of ever proving time travel possible. Thus, making it a mute point.

You can't change the past by going back in time. From 4,000 years ago, to 4 seconds ago, it's not concievably possible if it didn't already happen. It's not like we're going to wake up sometime next week, and some rediculous event turns out happening on the 29th. We'll percieve it as real-time. It's not going to just be imbedded into our memory.

[Speedster]

Now the question is: who came up with the song Let It Be? It wasn't John Lennon, because he learned it from you, and it wasn't you, because you heard it from records when you were growing up.

?????

You're right, it isn't you and it isn't John Lennon. Paul McCartney wrote Let It Be.

But as for the time travel. I can't remember where I read this, but I read somewhere this theory that a time travel machine would only be able to go between the time it was invented and the time you were. I like this theory, because time is densely complex that short of uncalculable physics that would rip the fabric of space, the only way to time travel is to have some kind of gigantic database that stores all of the information about the world in some kind of gigantic database. Almost like the Matrix, where the world is all numbers, too complex for a human to read but viewable as a total immersion experience.


Think about it. El Mojado, I'll use your example. Say Russia, in the year 3000 or whatever, decides to travel back in time to 2000 and nuke the fuck out of the States.

If in the year 3000 Russia does decide to bomb the USA of 2000, we'd already have a memory of it happening. seven years ago.

And on that note, once that happened, the Russians who went back to do it would be destroyed because they wouldn't be sent back because the bombing had already happened and because the bombing had already happened the Russians wouldn't send anyone back and the bombing wouldn't happen.


[EDIT] I've got the answer; it was Paul McCartney.

Damnit, you win.

That's a possibility, yes. But by that logic wouldn't time travelers from other universes just be able to come into ours?

[BBsKey]

What the hell is time supposed to be ?
As far as I understand Time is just stuff moving.
If everything would stand still there is no time .
But stuff moves. So time passes .
But I do not think it is possible to get back in time.
Only if you are an godlike beast that could reverse every move that is made.
Sometimes I thing what if every thing would start to move a little bit faster . We would not notice a damn thing. I think its freaky.
But moving forward is possible I guess why not. Just freeze yourself or travel fast.

[El Mojado]

That being said, if time travel becomes possible in the future, any and all time travel to any point in time in the past has already happened.

So meaning that if I go back and assassinate Vladiamir Lenin, then Communism in Russia would never happend? And then there would be no nuclear arms race, NASA expedition, Vietnam War, the inventions of the M-16 (then leading towards the shitty M4), F-15, F-16, SR-71, Su-27, and so forth? I think this is leading towards the "Alternative Universe" thread always posted on the Debate Zone.

No, meaning that if you were going to do it then none of that stuff would have happened anyway. And then you wouldn't do it. So it would happen. It's the worst case of catch 22.

But what about small things? Like instead of getting a decaf coffee in Starbucks, I get a decaf coffee in a gasoline station? Would that lead to a major economic break down or it would make Starbucks loose .000002 points?

I mean small things like that would never lead up to a giant reaction like if I were to kill Lenin. But who knows?

Who cares? Was Vladimir Lenin ever assassinated, leading to all of that? Nope. If anyone ever were to go back and assassinate him, we'd already have a history that involves Vladimir Lenin being mysteriously assassinated.

Here's the other side of the coin. Let's say that, hypothetically, George Bush got assassinated in 2004.

http://i21.photobucket.com/albums/b259/Matterialize/timetravel.png

This works. It's a situation where time travelers haven't "changed" the past, but they've still gone back and helped the true course of history along its merry way.

My point is, if you were going to travel back in time from the future, then it would already have happened and it would just be part of our history, it's like your changing time is already a part of time.

Now I think about it, I was wrong before, because Lenin being dead means Lenin is dead, so there'd be no catch 22, but what would happen is that you'd have no memory of any of the things that were a result of Lenin. Hell, you probably wouldn't exist. No one would recall Lenin's effect on the world and everyone would be happy because as far as they knew nothing had changed because the act you commited becomes part of the history between when you do it and when people are born and are made aware, they'd never know anything different existed. However, I would, because I'd still be in this universe and Lenin wouldn't have died because of catch 22.

That awnsers alot.
He's my understanding : The time travler steer the flow of history to the correct direction, meaning that Bush was assassinated and it was suppose to happend in order for histroy to happen.

But then that makes another question. Would that work in reverse? If I go foward in time, nuke all of Earth, then go back to my time, would that still occur in time?

[Shagg]

Time travel isn't real. If you go faster than light, you explode. Bada-bing bada-boom.



Well, we can't even get close to Light Speed to even test that theory. The only KNOWN thing we know is that if we go fast enough.. we become energy. :ahe:

[EPIC]

I'm time traveling right now. I'm going forward! Just at the same rate as everybody else. If you think about, everybody is time traveling.

[Deadhotkiller]

I don't see why traveling back in time is impossible. Changing history is impossible. Example:

- In our timeline, Lincoln is assassinated.
- We know that even with time travel technology we'd be unable to save his life, because according to history nobody ever went back in time and saved his life.
- If his life was saved, according to history, it's impossible that a time traveler could've done it on purpose (why would someone travel back in time to save the life of someone who, according to their own history, was never assassinated in the first place?)
- If his life was saved, according to history, it's possible that a time traveler could've done it unintentionally.

I hope that made sense.

Maybe he wasnt saved untill the day you saved him, like, lets say that someone saves him tommarow, hes still dead today but tommaro he'll be alive because thats when he was saved even though someone went back in time to do it, so up untill tommarow everyone thinks hes dead but after that he isnt. that probably makes no sense

I really wish people would stop saying time doesn't exist and that we made it up. We didn't make it up. It's not profound to say time doesn't exist, it's stupid.

If I slapped you in the face five minutes ago, that doesn't mean I'm slapping you now. There's a gap between now and when I slapped you, another dimension of measurement. We call this measurement time, and we measure it with minutes and hours etc, and all this measurement we made up. But the concept of time is not made up, it exists quite solidly, or else everything that will ever happen or has ever happened would be happening right now and forever, in which case I'd be dead and wouldn't be typing this.

Okay, okay. I know time exists, but I don't know of any plausible way which would allow you to travel into the past/future.

I mean, okay, let's say some how you can go into the past. Fair enough. It's already happened, let's go back, have a vacation. But surely that would mean you can go into the future too!? RIGHT?!

Let's go forward in time right now. What decides what the future will be like? THE STUFF THAT HAPPENS IN BETWEEN NOW AND THE FUTURE! And how can the stuff between now and the future take place if we just skip it?

If I jump forward in time five minutes, the universe progresses without me for five minutes. I'm taken out of the equation, then slotted back in five minutes later, but the equation still continues.
If I take the entire universe with me when I jump forward five minutes, then the entire universe will disappear for about five minutes, then come back, and essentially nothing will have changed (only, god help whoever time-travels into that five-minute window of nonexistence).

I understand where you're coming from, but you're only looking at half the angles.

[Urser]

Oh, god. My head hurts.

Well... When you explain it that way, I guess it could work. But I'll only fully believe it when someone makes a machine that actually does it.

[El Mojado]

I'm time traveling right now. I'm going forward! Just at the same rate as everybody else. If you think about, everybody is time traveling.

Yeah but we want more than X.

(I'm using a graph for example)
This is my view on time travel, X is the rate of which time flows. For example X=1. Meaning that X stands for the flow of time. Y intercept would equal to a certain date and time. Instead of heading towards that Y with normal X we would use 1000X for example. Speeding up the process, and of course using less of your time. So if I wanted to go towards a year in the future from today (10-30-07) then the Y intercept would be (10-30-08) and instead of using the normal time flow (1X) we would multiply the time flow (100000000X). And if I wanted to go back I would use (-10000000X) and go back towards my time.

But time travel and the flow of time is completely diffrent.

My head hurts

This thread was here before the reset and somebody posted this link http://www.tenthdimension.com/medialinks.php
I watched it and it really made me think.

[AidanC]

Here's my thoughts. You could possibly go back in time, but you couldn't change anything, because if you changed something bad that happened, it wouldn't have happened to the past you, so when the past you gets to the time when he traveled back in time, he would have no need to. But I think the whole idea is wacky.

[rcz]

maybe Ufos are us from the future, and they have grown taller. Since our past humans were alot shorter.and do to global warming and the temperature and rays have bleached their skins. and staring at the sun too much would have swollen their eyes and become huge and black. Sure some natural selection has occured like loss of ears and a bigger brain,which will come in handy to builed those time traveling spaceships.and also the reason for abductions is to steal our eggs/sperm to regain lost genes

[jayce]

Time travel has always been confusing and intriguing to me, because I don't get the physics of it. So I went to wiki, and while that page was maybe 40% understandable, I came across the segment on 'presentism' (there are no future or past objects) and that got me thinking about the Stephen King story 'The Langoliers'.

Maybe the present is like a bubble moving along a time-chain continuum, and this bubble contains everything (all matter), everything that happens is inside the bubble. You can remember history because those things DID happen, but all the matter that was involved in the past has moved on, and is still moving with the bubble. Ie, grandpa was involved in the world war, but there is no 'past grandpa' in the 1940s like some separate entity, he is here in the present. But all the events that happened to him, the memories, battle scars, those things also happen, and there is a recollection of it.

But should you try to travel outside of the bubble, either into the past or the future, you will end up in a void.

[Riddlebox]

The future hasn't happened yet, relative to our dimension, and the past already happened, so it would be impossible to go back, since time only goes one way.

However, it is possible that in another dimension, the present (in relation to our universe) has not happened yet, so you could travel to that dimension, and change ITS events, but not ours.

Same applies to a dimension which is 'ahead' of ours.

That's how I see it anyway.

statement earlier:( if time travel was possible, someone would have gone back in time already)

Maybe someone has gone back in time. They proceeded to change the future (our present). We wouldn't notice any change, as it still happened in the past.

I am confusing the hell out of myself.

[Kass]

It is only possible to move forward faster or slower in time, not to reverse time. And that's only relative to the earth's (everybody else's) time. You would need to move at an infinite speed to stop time. You would need to move beyond infinite speed to reverse time.

Time travel isn't real. If you go faster than light, you explode. Bada-bing bada-boom.

Science makes my head hurt. Aye aye aye. :wail:

Actually, he said you can't accelerate to the speed of light.
(Fuck yeah K-PAX)

[rcz]

what if they went back in time only as far back as when the first time machine was invented,which hasn't occured yet

[RabidMonkey]

To go backwards in time you would need to move at an infinitely fast speed. Basically you're going faster than everything else, so it's going slower, and slower, and slower, until it is going so slow it is moving backwards.
To go forwards in time you would have to slow yourself down to an infinitely slow speed, everything around you would be a blur, everything would literally be happening at once, past, present and future. And then you'd be going forward in time.
There are slight problems though, if you go super slow, everything will be happening at once, and everything will have happened, right down to the death of the universe if we were to go that slow. Also, going so fast would probably tear if not just you apart, but the very fabric of the universe around you due to the huge amount of energy let off. I reckon that the closest we will ever get for going forward in time is slowing ourselves down so that one minute for you is 100 years for everything else, for example. And the going backwards will be impossible, because you would somehow need to get back to the year 2007 from the year 2107, which you just can't do without going faster than time, thus making everything go backwards. So you can forwards (to an extent) but you can't go backwards.

Grim, if you went back in time and killed yourself, you would create a time paradox. Because if you were dead, you wouldn't have been alive to go back in time and kill yourself, which would mean that you didn't kill yourself so you'd still be alive, which would mean that you would go back in time a kill yourself, which would mean that you weren't alive to go back in time and kill yourself, which would mean you would still be alive to back in time and kill yourself. You understand?

But then again, I don't believe it is possible to go back in time and alter something, like you know your mother dies in a car accident, so you go back in time to try and stop it, and it was actually you that caused it in the first place.

Think about one of the sagas from Dragonball Z. The one where future Trunks comes in his space ship and warns everyone about the androids and shit. The kid version of himself wasn't born yet.

Also, have you see the movie "Time Machine". (Not the one with Paul Walker, the better out of two -- it might actually be called Time Line, not sure). Anyway, the main character's wife was destined to be killed. The guy even went back in time multiple times to save her, but she eventually died again. He soon realized he had to let it be. So, what do you all think of that?

I honestly don't know what I'm getting at, its 4am and I'm tired.

Oh and Matterialize, I find what you put about the future of something comes back and does something which hasn't happened yet very interesting. It gave me an idea.

Bravo, Mr.Scientist.

[DamnDude]

What are ya people babbling about infinite speed in order to go back in time? You just have to go faster than the speed of light.. And the speed of light isnt infinite. What you need is infinite energy to move matter at the speed of light, so what do you do? You bend the space so you dont travel faster than the speed of light, but get to another location before the light even set it course!

It kinda works like having two dots on both ends of a paper, if you wanna go from point a to b, you'd most likely draw a line from a to b, but the most reasonable way to get point a to b is just to fold the paper so a and b actually touch each other.

And what bends space and time? Gravity, and black holes have plenty of that.

But making a worm hole with a black hole poses a problem, you get shredded to atoms, and reconstructing you at the other location is pretty impossible, so you travelling back in time is pretty hard, but sending information back in time aint "that" hard.

[Matterialize]

worm hole

Dude, taking a wormhole between A and B doesn't speed you up - it just lets you take a shortcut.

I honestly don't know what I'm getting at, its 4am and I'm tired.

No offense, but you're not getting at anything because those are just complete works of fiction. I could bring up TimeSplitters: Future Perfect, and how at the end you see the entire war-ravaged landscape change into a beautiful forest vista because Cortez has gone back in time and prevented the war from happening, but that defies logic.

Although, that bit with the guy failing to save his wife's life over and over again is sort of what I'm getting at, but is still flawed and doesn't make sense.

[JonC]

I never thought I'd say this, but I think you people smoke entirely too much marijuana.

It was 4am, disregard most of what I said. Especially about Dragonball Z. I think there was a point behind it, but I do not know what it was now. Oh and I never played Timesplitters btw.
