Timetravel
 

A Discussion in the following Thread: http://forums.filefront.com/starbase-42/216792-trek-time.html made me decide to open up this one to discuss the issue.

Seeing as the above thread is Star Trek related, i don't want the thread being closed down due to the topic being changed to something that doesn't relate to Star Trek.

Anyhow, do you think Timetravel is possible? - If so, explain why you think it is, and likewise, if you don't think it is, then again, explain your reasons for thinking so.

I have somewhat given my reasons in the other thread but for those of you that don't wish to go and have a look:
If you can work that out, good job, if not, well... sorry for the confusion.

Re: Timetravel
 

personally, i dont think time travel is possible, or will ever be possible.............

plus, imaging if you screwed something up in teh past.......

Re: Timetravel
 

Nah - I very much doubt it's possible.

If it was - then what would happen to people's memories? Could they be altered as well? Without the person realising?

Time is closely related to consciousness, right? Think about sleeping for example. I just don't see how you could travel time without it having to be a mind trick of some sort... :uhm:

Re: Timetravel
 

Is it possible? It's already happened!
Clearly you don't watch enough Superman :cort:


yeah, I do not think it's possible.

Re: Timetravel
 

Not possible.

What happened in the past is set in stone, if you were to somehow go back in time, the future would not be the same, no matter how careful you try to be. What happens, i thinkm is that if history is altered in any way, it creates another dimension with new possiblilites and histories.

Re: Timetravel
 

Not possible, you can not control time, what happend lays in the past and what yet has to come lays in the future. You can't time travel.

It just doesn't make sense: if you were to go back in time to prevent something from happening (or instead make simething happen) then it already would never have happend in "your starting time" to begin with.

If you would travel to the future there then every single action that happen between the moment you left ("now") and your destination time would affect the future. There is no way that the future knows what I did in the past, all these different actions could leed to an endless number of different futures.

Re: Timetravel
 

time travel isnt possible and it whouldnt matter if u went back in time beacuse that whould mean that time already passed when u went back and so nothing whould change unless you didnt go back its impossible to change the past but its possible to change the future

Re: Timetravel
 

Ever hear of the Philidelphia experiment?
I'll be the 1st one to argue that it may be possible.
I like to believe that it's possible, and prehaps it was already done. Maybe the computer is from the future and our present....
Maybe we won the war against the germans only because we once lost it in a another time demension..It may be possible, I would like this thread to go on..so I argue that it may be possible,

Re: Timetravel
 

I do believe its possible, only not yet... We've proven that we could fly too, and that was "impossible" a hundred years ago.

And as for changing time, you don't know the laws of time, so its only pure speculation.

Re: Timetravel
 

I doubt its actually possible, but if it is, I will be spending alot of time reaking havok here and there.

Re: Timetravel
 

There is a really good reason that when you try to explain time travel, it makes no sense. For example the going back and time and ending your own life as a baby senario, makes no sense whatsoever.

Time is not real. Time is simply a linear perception that humans use to help the world tick over, and to get things done. Time is an invented perception of the world we live in, and has no physical basis in the real world. As far as the world is concerned, it just exsists, period. No past or future like we see it.

Our minds are rather small and it's very hard to comprehend things in any other way then in linear time. That's okay though because the universe is ment to be that way. So just don't give it too much thaught;

Lession: time travel is impossible.

Re: Timetravel
 

I dont believe its possible however some astronomers have created theories believing that black holes sink through the fabric of time.

Have you seen the special halloween episode of The Simpsons where Homer rebuilds the toaster and goes back to when dinosaurs ruled? He killed one thing and that changed everything in the present.

Even if they find a way it wouldn't be moral to everyone and to religions. People would want it for themselves anyway to give you an idea of what would happen if such a thing was created I'd give you an example, if the Germans wanted a different outcome to all wars they were in what would happen to the present?

Re: Timetravel
 

The past, probably not, but we shall wait and see.

Traveling into the future is a different matter. I don't know if you have heard the story of the two sisters and the rocket ship: There were two sisters on earth. One of them get onto a rocket and was sent into the cosmos for a considerable time. When she returned from space, the sister in the rocket ship was much younger than the sister on earth.

I don't remember that story exactly, if I watched this video I have, I could tell you, but I don't want to watch it now. :p Anyways, the sister on the rocket traveled into the future, by way of space time curve, or some jazz like that.

Anyways, I found this wierd article, you might want to READ

Re: Timetravel
 

Your describing Stephen Hawkings theory of special relativity you can find the article on www.howstuffworks.com I read the article, and I almost fell asleep it was that in depth.

If your smart and ready for new concepts read it if not dont.

Re: Timetravel
 

If time is not real and doesnt have a physical level , then what is it that continues to make our bodies and possesions degrade over periods of "time"...I don't get it, time is real....or is it? Your opinon,is cool..but I think that time is very real to all of us.

Re: Timetravel
 

Time must be real, time started (with a possible big bang) and will (in theory) at some point, will end.

Maybe calling it 'time' is the part that is making this sound wrong, but there is no other name for it. No direct insult to you, but you've just complicated this matter even more. Saying that time doesn't exist, when it does (you wont stay your current age forever) - humans - like everything else NEED time to exist, else we would not exist.

This guy has a point, and i do also agree that your opinion is somewhat unique, just a little baffling.

As for Black Holes, they are suppose to slow time (although this is again some sort of theory, seeing as we have never encountered one, yet, if we did, besides knowing that it's hovering about our solar system, we wouldn't actually notice any difference, unless we were maybe on another planet and time from one planet and another being different - although, it would be anyway as that other planet would have a different sun, different days and different day times (a day elsewhere may last 31 hours) - in which case, would that be classed as a day or would everyone still go by the earth time?

I can see this getting really confusing!!!

Re: Timetravel
 

i think that time travle will be possible because we manged to build boats when we learnt we built trains when we learnt to so ithing when we learn to we will be able to time travle

Re: Timetravel
 

In fact you can travel forwards. One of the astronaughts who orbitted earth currently holds the record for most time travelled, travelling backwards is more or less impossible though. If you did travel back in time, you would be a duplicate copy of yourself. Confusing, but it is possible to travel forwards at the moment. It was on horizon a bit back.

http://www.bbc.co.uk/science/horizon...metripqa.shtml

That's the program.

Re: Timetravel
 

Any thing is possible these days now. Like people already said in here we can fly and that was impossible 106 years ago. Computers and Cars people thought would never happened, same thing with the light bald and tv and radio. Going into space every one thought that would never happen at all and we did, we walked on our moon. Every thing is possible. So yes I do believe we would make something to take us back in time.

Re: Timetravel
 

No, time does not exsist. I'm not saying that things don't change, they do, but they don't change as time goes on, the just change. Its humans that perceve the change as the future, past or present. Its all in your mind.

"In the past bill made a cake"

Bill still isn't making a cake, in the past. It's just a human perception that lets you refer to things that have happened. But its not still happening. There is no past and there is no future, and there is no present. Everything just is. Your just perceving it in a way you comprehend. your human.

Re: Timetravel
 

I think time is very much possible, in fact we are able to travel into the future right now, the faster you travel the more forward in time you jump, an example is there are two twin brothers and one of them is an astronaut, now the one that has gone in space because of traveling so fast is now about a second younger than his brother back on Earth, of course to travel any considerable distance forward in time, you would have be traveling much much faster than anything we are capable of now, something like close the speed of light. (Oh and these two brothers are real, Its not a story I made up as an example, one does work at NASA as an astronaut)

Now traveling back in time is a whole other thing, and would be much harder, as of our current knowleged is not quite possible yet. Thought there are many theories, and actually someone attempting it, thought only actually trying to send a particle of light back in time. And there are theories that say that if you did actually manage to travel back in time, you wouldn't actually travel back through time but instead you would enter a parallel dimention where events that occured in your dimention haven't occured yet, so in a sense you are in the past, though in relation to the dimention you came from in terms of events, and you would never be able to return to your own dimention, since if you tried you would only be going forward in time with all the changes that you made in the new dimention you entered, so you would be stuck there, never to return to your orriginal dimention.

Edit: Oh someone just posted about the astronaut right before me, thats what I get for typing for so long ;)

Re: Timetravel
 

I don't think time travel is possible. In fact, I pretty much agree with what FileTrekker posted last. The past has happened, then its been done, and that's the end of it.

The future hasn't happened yet, and isn't happening anywhere else, so it can't be visited.

I do believe thats its possible to recreate time, certainly the past could be recreated, and with enough technology/money/space you could in theory recreate characters and settings from the past, who think the same as their originals, then live in that past and play it out again.

Re: Timetravel
 

Not ageing by one seccond is not time travel. What you are suggesting would mean there is two of him at once, so there would have been two spaceships at once and so it would have been observeable. Your simply saying the guy did not age.

Sounds fancyful but really it has no basis whatsoever in logic or fact. :uhm:

Re: Timetravel
 

I think you could do the illusion of time travel because if you travelled faster than the speed of light, but if you slow down then you must combust or something. Or would you combust travelling at the speed of light anyway?

Re: Timetravel
 

well.. i dont know if timetravelling will ever be possible, cuz its so strange.. i mean, everything u would do in The Past, would make a whole difference to The Present. And the people living in The Present, would suddenly change? or sth? e.g., if you rescue some1 from being murded in The Past, would he, if you 'flashed' back to The Present, suddenly pop up cuz he is suddenly alive ? its just 2... strange..

i do think however, you can actually slow down time. I once heard something like; if u were in space, travelling w/ the speed of light (or faster), then, time slows down...
So, like (in the future), if we send an Astronaut up in space travelling at the speed of light for a few years, and he would return, like on earth 10 years would have passed; while he was only in space for a few years.. something like that ... it hasnt much use though.. lol..

timetravelling would be really cool though.. u could do everything...
it would also be really scary... for the same reason..

Re: Timetravel
 

It's impossible to really comprehend the implications of going back to the past. It isn't physically possible, even in theoretic physics it isn't unless we somehow muster half the power of the universe to "skip" time, but that ain't happening. I see travelling forwards as possible, but going back isn't.

Re: Timetravel
 

I don't see how going forward in time is really any more possible than going backwards in time. It may be possible (like that astronaut) to travel quicker through time than everyone else, but to travel forwards in time in the sense that you are actually physically moving to a different stage in life as its known, would be impossible.
Moving quicker through time would have no real advantages though, as all you'd be doing would be writing your own "present", not actually going forwards in time at all.

Re: Timetravel
 

:gpost: What I cannot comprehend is - if you've not done it yet, how can you look at it before it happens? What if you change your mind when you go back to the present? I believe it's just as impossible to travel forwards in time as it is backwards.

Re: Timetravel
 

Is'nt this somethign to do with parallel universes (like the string theory etc.) and that everything that could possible happen (infinite things) has already happened in one of the infinite parralel universes.

Now surely there has to be some way of connecting that to time travel into the fuure?

Also:

Is it true that mass cannot travel at the speed of sound? I heard it somewhere but don;t know if its true or not. If so then thats that theory out the window :\

Re: Timetravel
 

Well theoretically speaking, you could probably make a calculation to determine how many seconds/minutes ahead of your own time you want to be once you've finished "time travelling". It is much more possible than going back in time, because to going forwards has already been done, going back is impossible, because there really is no way to turn back time.
The time travelling that has been done, is really only skipping times. Like a minute only lasting 30 seconds. To pinpoint an exact time would be possible, but you'd have to be going very fast.

Parallel universes [if they do exist] would be in time with our own, that's why they're parallel. However things could be completely different.

Re: Timetravel
 

If you get ahead of everyone else by "time travelling", then you would only be ahead whilst you were moving at that greater speed. As soon as you slow down back to a more "normal" speed, you would lose the advantage in time that you had previously.

So it might be possible to move faster through time, and whilst you were doing so anything you did would be noticed by people moving at normal time, a little while after you did it.

But then when you begin to slow down, the difference in time would be reclaimed, until all is normal. Though you would have aged faster than others, you would stop doing your actions ahead of everyone else.


Travelling faster than the speed of light is impossible. If you went faster than it, then presumably you'd cease to exist, as you'd be moving faster than the image of your body.

Re: Timetravel
 

Practically you'd need to be in space to do it, because to accelerate at such great speeds would require a lot of space. You would essentially "speed time up", when you stopped you may be 2 minutes ahead of the time you left at, when it had only took you half that time.

Re: Timetravel
 

It wouldn't really be speeding time up. Time is a constant. In fact, trying to define what time actually is is quite hard. Measuring it is easy, as we have managed to do that, but trying to find the speed at which time actually moves, is a problem. If solved, then it would open up a lot of windows into the field of "time travelling"

I guess the way to find it's speed would be to measure the rate of the expansion of the universe over a certain distance. However, this would be hard, as the area would need to be large, very large. The problem with that is that finding somewhere big enough, which is totally devoid of gravity for the whole distance.
Another problem is that you can't get a set distance, because you can't look ahead of the universe and its path of expansion.

Re: Timetravel
 

It may be a constant, but to time travel you have to be faster than time, that creates a whole new set of problems really I suppose. It's all very theoretical stuff and we really still have no means or ways to measure time or any variables it may have.

Re: Timetravel
 

This to bound to get very confusing,time travel always is.

Re: Timetravel
 

Exactly it is just like Grimme says, the only thing we can really do is guess and discuss.

Re: Timetravel
 

time travel is rubbish. it's fantasy, existing in science fiction only.

Re: Timetravel
 

If we or you could be exactly the same for a second, you could time travel, but as long as you have the slightest change per a second, you cant....

Re: Timetravel
 

Lets just summarise a little.

Most people think timetravel is impossible, some think it will be in the future, and some don't think time exists.....

I was having a discussion with a friend earlier on today about this topic, and here is what we conclused: If timetravel is possible, then we would not know. - In theory it wouldn't matter.

Think of it this way, if you had a time machine, and were to travel to the past, you would be changing your own existance. Thus, you wouldn't actually arrive at the past, you would simply be erased from time.

Demo: You and a few friends build a fully working machine and plan to go back intime (say there are five people) - this machine can only hold three max, so three people get in, and decide to travel back in time say 500 years. Going back in time would corrupt the future as you know it, thus, you wouldn't actually arrive in the past, because (if you did) you would change the future. The three people that got in the machine would simply never be seen again, and the other two people that were left would simply believe that there friends were trapped in the past.

Either that, or the time machine (from protecting 'time' wouldn't actually work)! This being the case, you can't travel in time as you would simple change your life and end it.

As for going to the future, that would again be somewhat impossible, as if you went to the future, it doesn't yet exist, so how would you get there? thinking of it logically, if you leave your time to venture into the future, what could have happened if you didn't go would be the future, you going into the future would work as it doesn't exist

This theory works better for going back in time (makes more sense than the theory of going foward), but the general jest of it, is if you go back to a time before you were born, you wouldn't actually get there.

Edit: Also, the theory that FT said, we were also discussing that, and again, came to a conclusion, i understand what FT is saying, that being:

Earth has a gravatational pull on us (humans and what not), the sun has a gravatational pull on Earth, and in the center of this Galaxy there is a massive black hole - of which is having a gravitational pull on all the Suns. With this, there is more than likely something in the center of the actual 'universe' that has a gravitational pull on all the galaxies that are scattered about - this would be a good place to assue the big bang took place.

So, time does exist, it just so happens that it is different throughout different parts of the universe

Re: Timetravel
 

No you would have aged less than those moving slower than you, to you less time would have gone by than for those you left behind, so when you slowed down, you would see that more time has passed for them and everone would be much older then when you first started your journey, you wouldn't notice this until you slowed down and saw that to everyone else more time had gone by than what you experienced.

Re: Timetravel
 

It is possible to see into the past, but not to travel backwards or forwards through time, that's final, time in the future does not exist (yet), so you can't go there, time in the past has already happened, and unless you could somehow reverse the every single process that has happened (except your birth and bodily functions etc), it is impossible to travel backwards through time.

I say it is possible to see into the past, as light is what makes us see things, and thus if the light doesn't reach us till the event has past then we will be seeing the said event after it has happened.

Which brings up the point that things happen when they happen, not when you see them happen, so if you were to 'travel into the past' and be able to see everything as it was, you could not affect it because it has already happened. I'm confusing myself, so ignore that bit if you don't get it.

Re: Timetravel
 

If you ask me it may be possible but it also may not i dont know.
But if it is possible then i hope we will never discover how, because there will always happen something bad: a terrorist that goes back in time to use advanced technology to blow up all the nuclear powerplants and desroy the world, a nut that goes back in time and takes over the world, some nice guy that thinks he can save the world by killing hitler caosing some sort of chain reaction what makes a world war ,....
And thats just the tip of the iceberg, here are just way to many grazy people on this planet to make it a safe idea to timetravel, each thing you do in the past has a counter reaction, even if you kill a bug you might alter the whole past.
I know im overreacting but still it is way too dangerous to timetravel.

Re: Timetravel
 

There will never be a time machine. It is possible but only theoretically.

Re: Timetravel
 

Well that would be the only way to "go back in time' , one would habe to invent a machine that would be able to travel faster then the speed of light so you could take over the light that caused tens, hundres, thousands of years ago and then look back to see what this light shows.

Same with the stars, by lookign at those stars we look back in time, since between the point of the start emitting that specific bundle of light and our eye catching it is a very large amount of time. So we only eventually might be able to see what light reflected into the universe (no fancy abiltiy to "walk around in the past" ). It would be more like a topdown-view experience.

Re: Timetravel
 

Of course time travel is possible! Silly.

Re: Timetravel
 

Re: Timetravel
 

pfft! why do you think i want a delorean? to make it possible. everyone knows that the only suitable time travel machine is the 1982 DMC-12 DeLorean. hah, watch back to the future parts I, II, and III in a row, the genius of the interconnections between the three are amazing. and the quality at which they thought out the series is wonderful. i believe its entirely possible. not easy, not very soon either. but i think we would have to master teleportation first, then tweak around with it and thro w few more gizmos with long names into it, then we might be able to... i don't really expect to see it in my future though. i'd say i've got bout 12 years left before i get killed by doing something stupid.... these are all just my thoughts, i'm not a "truth-telling" textbook. believe what you like, i'll believe what i think

Re: Timetravel
 

Time also seems to be the result of the universe expanding
