just thought i'd toss it in the circle of talking.

do you think it's possible, and if so, what kind of impact on human society will it have?

Time paradox: If you travel to the past and kill your grandfather when he was a child for example. This is why I don't see time travelling as a posibility.

<div class='quotetop'>QUOTE(Tulac @ Mar 6 2007, 09:44 AM) [snapback]282059[/snapback]</div>Yes well, what happens next is the Space Time Continuum unravels and the universe implodes upon itself and all manner of strange and big and possibly painful things happens. It's like trying to divide 100 by 3 on a calculator, except instead of writing .333 etc to the end of the screen it comes up with a Syntax Error. Somethings gotta give, and the usual theory is the universe.
If time travel was ever invented, I reckon it would be a bad idea to go around killing grandfathers. The closest we'll ever get to time travel I reckon is like what happens when you fly around space at high speeds and you return to Earth a few years younger that what you whould have been, ie. had you not flown around space at high speeds.

Maybe you should make a promise that you will build a time machine in future and return to this day to meet you.

If you would promise to do it, would you appear next to you all of sudden?

Dear lord...

<div class='quotetop'>QUOTE(Tulac @ Mar 5 2007, 11:44 PM) [snapback]282059[/snapback]</div>dont you think that if you were realy able to travel in time, you d be do something like that? what if its "constant" that your grandfather ll survive and even if you travel back in time, it already happened before you was born, so even if you try, no matter how, something would happen and you grandfather d survive otherwise you wouldnt be able to get to the time mashine..or whatever.

OR what if each time you travel in time, you create paralel universe, like alternative, where you can do anything you want and you r just copy (actually cut) from your own universe.

You are mixing up two distinct things r.u.s.s., 1) time travel and 2) parallel universes; maybe they are connected in ways we can't even imagine. The true is, none of us know enough about this to be able to draw a decent conclusion, all we can do is speculate.

I don't believe in that time paradox thing and how it could make the universe collapse; if someone ever invents a time machine, that's probably being a part of what is supposed to happen; if that person travels to the past and does something there which even terminates his own existence, then maybe that was what was supposed to happen, and the line of time will adapt - maybe someone else in the new time line invents the same machine and travels back to do the same thing. Even the smallest change in the past could have catastrophic consequences in the present - just imagine a time traveller taking one of our "modern" diseases (like for example aids) and spreading it 200 years ago.

I don't believe in time :P
For me, I view it as a quantification of change and something inherent to our (mental) experience.
I find it an odd notion that the past would be thingey residing somewhere.

Yeah, you could play games. Try and reverse laws if you like, or recreate instances of potentiality, but there's no difference in the way one would experience that.

I believe if you went back in time and killed your own grandfather, several things would happen, only two of which I can suggest;

1. In killing your grandfather, you would cease to exist in this reality.

2. The universe would split, creating; One, a universe where your grandfather continues to exist, and you disappear the moment you made the killing blow. Two, A universe where although your grandfather has died, you continue to exist.

I also think that if anyone was approached by theirselves, it would disrupt the universe flow. Again I cannot be more articulate because they are simple beliefs I hold.

I'm with doubler here. Time doesn't exist, it's just a concept to clarify things up a bit. If you could ask a, lets say, slug, about time, it wouldn't understand. There is only to be or not to be, not past, present or future.

well apperantly even if you meet someone who look sincredibly like you it can cause deep psychological disturbance, because you actually never see yourself. mirros are only reflection (sides are changed)

If time travel is soemthing that's invented in the future would we not see time travelers today, taking a visit to our time? Let's say they have a "keep it low profile" codex, would not at least on of them make a mistake or something like that? And there would be millions of time travelers because more to the future you go, time traveling would probably be more widespread among common people.

The time travel could be useful in some ways. If you could travel trought time, you could check if any disasters would happen, then you can prevent them in the future.

Could time travelling also answer to the big question: Why?

Cats hate water.
Dogs usually swim.
Cats don't play fetch.
Dogs retrieve items such as bones or sticks from playing fetch.

Oh I get it! Do something in the past and something like that will happen.

WAKE UP CALL!

1. Time is something invented by swiss ppl so they have an excuse to sell us clocks and watches, before the swiss did this we had the sun and the moon to show us "the time"

2. With the invention of time came stress. that's right, STRESS :wallbash: the #1 reason for burnouts and such. things like "OMFG i'm late for work" and "WTF it's X past XX already?" (replace x with any given number) I.E. not the best invention ever.

3. The possibility that timetravel will be abused is ******* HUGE! Approx 70% of the survivors of the 2nd world war will attempt to go back in time to kill the bastard (hitler) himself. Bloodwrath is imminent, killing the murderer of your husband / child etc. total chaos will emerge and the world will slowly but surely crumble into nothingness.

4. Who in his right mind would go back in time to kill his/her own grandfather?!?!?

5. EVERYBODY will try to go back in time to "prevent this mistake from ever happening". Chaos is, once again, very imminent.

6. (the first positive thing) you can try and stop the swiss from "inventing" time, effectively changing Timetravel to Whatevertravel.

7. yes indeed, there will be numerous time clashes (Timecop, Cycles of dawn, Groundhog day, etc.) In the end, the fabric of time will not be able to coop and the universe will end.

I hereby rest my case. :ok:
Shoot me if you will.

<div class='quotetop'>QUOTE(Tulac @ Mar 7 2007, 09:45 AM) [snapback]282240[/snapback]</div>you r right. but maybe, it d be somethign controlled by some kind of big organisation which controlls everything, like "this second can have max 50 visitors from any future, no more" so there d be limited amount of people going back, or world could be destroyed of course and time mashine could only exist for few years

Without getting into quantum theories; We know that we can travel foreward in time. We do so all the time after all. Backwards though is trickier..

I believe also that if it is possible to go back in time, and someone does this, he would not change anything, because whatever he does would have already happened in whatever time he went back to. In other words, I think that it would be impossible to change the course of history, because if you did the butterfly effect would most probably make you never go back in time, or even get born if you went back before you were born.

Another possibility would be that if we change something, we create a whole new universe, where whatever change you have caused to the world would be what "always" had happened. You, being of the universe you came from, would not be affected by the fact that this new universe never produced "yourself".

I think its supposed to be a cat trying to be a duck and a dog, because of a Time Paradox that has been caused by time travel.

(EDIT: Please ignore this post, due to slow loading, I missed Duss. T's post)

Sure it's possible. Hiro Nakaruma can do that !!!

Time travel to the future is not an entirely rediculous item, one must simply slow down enough to allow time to pass him by, however, a machine that could travel to the past is only able to go back as far as the time at which the machine would have been created, if you attempt to return to a time before the machine existed...

It's perfectly possible in theory, but highly improbably in practice.

If Einstein was correct, then time is dependent on the speed you travel with. So if you'd be traveling faster then light, you could travel back in time.

If on the other hand you'd be slower then not moving you'd travel forward in time.

There's only slight catch to both...

Things with have any mass at all (and all existing things in our universe have mass) can not reach the speed of light (let alone go faster). While on the other hand to be slower then standing still would require to be all mass and no energy at all, but guess what, if an object wouldn't have any energy, there's be nothing to hold the atoms together and that object would in fact de-materialise.

So it's possible in theory, but doubt it can ever be done in practice.

We're travelling fowards through time now. Just not at a very fast rate.
And O SHI-- SEB IS BACK!

Oh, and to come back to two points that Tulac and russ mentioned...

If you could go back in time and change something, that would effect the things to come.

1) Lets say you would create a time machine today and go back in the past with it. You'd go back to let's say year 1925, find Adolf Hitler and kill him, so there'd be no Nazi movement in Germany.

Not counting the fact you'd be causing great differences in the political balance of the world (who knows what would happen between the Soviet Union and the Western world if there would be no WW2), you would also do something else.

You were born after WW2, so when the date of your birth took place (in the now changed time line) you - or the rest of the world would know nothing of Adolf Hitler, so even if you'd create the time machine again you wouldn't go back to the year 1925 to kill Hitler, so you wouldn't change the timeline and it would again return to the way it was before - where again you'd change it and so on. It would be a cycle that would loop up to the point where you went back in time and both timelines would most probably colapse at the end of it.

2) About something being constant...
Seeing how the time line did not colapse yet and we're living fairly normally inside it, there is also a possibility that you can't change nothing.

Imagine you'd go back to the WW1 and try to kill Hitler there (yeah, I guess I'm obsessed with killing a dead guy) and you'd find him on the frontline. You'd shoot, miss and kill another soldier who (if not killed) would have killed Hitler.

So if you wouldn't go back in the past Hitler would be dead. The fact he wasn't was because you tried to interfeare. By trying to change sometihng in the past you actually made things the way there were in the timeline you know, so you would breake the timeline if you wouldn't travel to the past. This would mean there is a constant and whatever you would do wouldn't effect anything, because it was suppose to happen that very same way. In that way it would be probably that you'd do more damage by not going into the past.


Can't you just tell I love such stuff. I really like "removing the dust" so to say off these different theories of mine.

<div class='quotetop'>QUOTE(Sebatianos @ Mar 12 2007, 11:25 AM) [snapback]283121[/snapback]</div>so maybe if now somebody build something like chamber which "materialises" ..shattered attoms in the chamber, people in future could maybe travel from future, when they step in to the chamber, being able to travel in timeline: <chamber built, future) and if they travel too much in to the past, they stay dematerialised among dinosaurs o_O ..or near hitler=)

btw it Would do more harm if you didnt travel back, but you are just not able not to do so (cause its constant). so if its constant, we can do whatever we want, everything is already "written"

<div class='quotetop'>QUOTE(_r.u.s.s. @ Mar 12 2007, 07:42 PM) [snapback]283244[/snapback]</div>That's the big question. Is everything already writen or is the future an open book?

Come to think of it...

If the future is already written then you can't change anything. But if it's not, can you then even travel into the future? I mean, is it already there?

Oooh, I'm in a time vortex right now! I feel like it is 2005 again ;)

Welcome back Sebastianos :D

Nice to see you 'round again...

IF time is constant, it must be "written".
but maybe there s just some kind of circle like our history still goes in loop, from big bang to collision of universe(another big bang). but we cant understand it now, like neanderthalers couldnt understand earth is big ball

But time is not constant. It is a construct that we (humans) use to help chart our "special" moments of existence. There are numerous examples of tribes of people that do not have words for "past" "present" and "future"...

Further proof that Einstien kicked behind (if any was ever needed ;) )

That said, if it was possible (which I believe that it is fundamentally not,) I would love to go play around in medieval times.... The early Chinese dynasties would be my second choice, or Rennaisance, Europe...

I believe it's a matter of perception :D

i'm alive. so all your theories... go to bed, people. :P
