Time travel

[corkft]

Infinate number of universes, infinate number of timelines. Everything that has happened, is happening and will happen, co-exist. The only trouble is finding the right door to get to where you want to be. And being at this point in our evolution, we only know the door to the present. :wacko:

[Matthew]

hagg3rty, please do not advertise other forums. Check out the rules here.

What is the present? Everything we see is in the past, light takes time to reach us.

[hagg3rty]

Im sorry I should have read the rules i apoligize

[corkft]

I would say the present is what we each experience at the moment. So, Matthew, are you saying time is nothing more than distance? Is time limited to the speed of light? I think not. Perhaps looking into a mirror I am seeing myself as I was a fraction of a nanosecond ago, however what I experience is the present me. I was just looking at the word present, take it apart, PRE SENT. Perhaps you are right after all.

Is time a quantity to be measure or a quality to be enjoyed? As per Einstein, guess it's which hot think you are involved with , the stove or the babe.

[Arramon]

time travel still seems like it may not be possible when you have a decay rate on everything.... losing composition & structure... matter and light included. Can we reverse the affects that the progression of Time places upon everything? To me, that seems like someone would need to halt the progression of the universe in order for this to happen. And we are farrrrrr from that... =P
Even if you travel so fast that you are going faster than light, and in essence you may arrive at a place before the light does, which may let you know what is coming, sort of foreshadowing your future... but how can we get to a place before its there when that place is in its own progressive state? Trees do make sounds when they fall if noone is there to hear it..
And to travel to the past... when its already past... how is that even conceivable? The past has already happened. Those lives are long gone and dead, along with anything that is behind us... How do we make ourselves recreate what once was as it once was? Everything that once was..... maybe in some sort of holo-room of the future... but I can't see our universe as a mirror of something else that is just a reflection of something that has happened or is going to happen....
We are living as a constant.. and moving upon a plane of existence that deals with placement of individual time-periods is more than we are capable of. o.O

hmmm...

We could create the past. If every piece of matter affects each other, (eg. gravity), then you could measure every piece of matter. The sheer amount of data for a project like this is inconsevable, but if you could measure every piece of matter (including anti-matter), you could recreate the universe. And rewind it. So you could come to a point where you could create a scene in a particular place/particular time. There are only two things preventing this from working; quantum unpredictability, and choice. But it is doubtful that the public would get such technology if it were ever invented. Imagine how easy it would be to spy! Just recreate a scene with someone talking, or someone writting instructions for an attack, you would know everything!

[rahuldandekar]

But what about the future?

P.S. I posted on page 4.

[Matthew]

Well in theory if we had measured every particle in the universe, we could, ignoring chioce (maybe we could include choice), create the future. Though this would be a possible future, for on a quantum level things are only governed by a structured chance. (I.e. Things must follow certain laws.).

But a computer that could do something like that would need to be able to go though more information than we currently store on the whole Earth I think.

[damienpaul]

A very disturbing mental image arose out the headache i got from reading all this imagine the critters from the langoliers chasing michael j. fox in that car on his way to kill his grandma....frightening, gotta stop eating pizza after midnight.

[Matthew]

Time travel is one of the hardest thing to get your head around.

[damienpaul]

i wholeheartedly concur! but it is one of the topics that cannot be let go!

[Kootenaistar]

Just a quick one here. Haven'tt seen any reference to time-space continuum. It has been explained to me some, but my old peabrain can't explain it to you. Does it not slip in here somewhere? :unsure: Seems to me it should, or is that just what has been being argued here?

[Arramon]

Say you could re-create everything... EVERYTHING. Planets, stars, black holes, nebulas, galaxies, more stars, more nebulas, more galaxies... blah blah, and all of the tiny, tiny, tiny miniscule events that happen every nano second... be able to rewind the progression of Time, as everything has happened so far (dont forget about Sue taking a coffee break at 4:15pm), all the way to the point that you might want to be...(nevermid the fact that a billionX1000 individual events were probably just erased, seeing as how we could never really know what happened in all places at all times...) and start the progression from that moment (How you kept yourself together & sane throughout this process is anyone's guess). That would be a fast & strong computer simulation, that no amount of processors we have today could accomplish, but it would still only be a simulation. How do you create stars? and blackholes? and galaxies?
"Stars form deep inside vast clouds of interstellar gas and dust called nebulae. In the cores of these intensely cold regions — only 10 degrees above absolute zero — the pressure from the heat of the gas is insufficient to support the weight of the surrounding cloud, which then begins to collapse on itself."
"There is evidence both in our own Milky Way galaxy and in other galaxies that large black holes occupy the centers. At the center of the Milky Way, for example, the presence of a massive black hole is the only reasonable explanation for the great velocities of stars orbiting the core."
"The visible matter in the universe that makes up the familiar structures of the galaxies are: Hydrogen: 72-75%, Helium: 23-26%, All Other Elements: < 2. While the process of nuclear fusion has very slightly increased the quantities of helium — and produced almost all of the other elements present — these figures are practically unchanged since the earliest years of our universe."
So how do you simulate & actually recreate that?
To me... thats to much for even my imaginary processes to conceive, let alone think that I could possibly alter any of it.
But, I&#39;m glad my imagination works anywayz =)
Its fun to think that we can... who knows? Maybe one of these galactic millenia we might...
Or else another species within a different part of the universe does before us, and tries to aletr things, and forgets, or doesn&#39;t know that we exist/existed at all, and restarts the progression of space/time without us in it. oi&#33;&#33;&#33;

[damienpaul]

The changes to history will have an indeed inexplicable and likely to be dangerous effect. Also, if the time loop theory is true then, changing the future could have a profound effect also.

[Planetwatcher]

Arramon, that is deeper then even I want to think about.

[Littlemews]

Past is only just a memory, and future is our imagination....
There is no time travel exist, if they do exist, ppls in the future they might travel back to this Era and change the history...too bad there is none. <_<

[Matthew]

A simulation would have to calculate every quantum function, with nothing more than a chance that something might happen, then there is choice. Could it simulate choice?

[damienpaul]

Could it simulate choice?

that would have to be a seriously powerful probability generator

[fortyseven]

You can&#39;t argue against time travel by saying we haven&#39;t met any time travelers. Ppl argue the same about aliens. You aren&#39;t disproving anything you&#39;re just narrowing the possibilities (i.e time travelers haven&#39;t visited-aliens haven&#39;t visited or can&#39;t)

Time travel is possible and I know how to do it. I&#39;ll explain more in my next post.

[Hydrok]

Well i cant believe that i&#39;m going to do this but....

Michael Chricton does extensive research on the topics he discuses in his books, look at the back 20 pages and you see book after book, source after source, that backs his claims. So i wouldent totaly slam Chricton to fast.

[apocalypse]

Well when you look at general science fiction,it makes time travel look stupid,every film out there is plain stupid in its unexplained state,you have to fill in the blanks for the failed physics inside the story.

Terminator being an example:

The terminator is sent back to kill sarah o conner,the mother of john o conner,the mission is to destroy the mother so that john is never born.

Now you have a slight problem here cos should the terminator succeed there will have been no reason for the terminator to have been sent back in the first place.

Your other problem is what revealed in the sequel where kyle reese the protector of sarah in the first movie is john o conners father&#33;

OH DEAR

Why does this make no sense to me you wonder,
well there must have been a time where kyle reese WAS NOT john o conners father RIGHT?

I mean before skynet interfered and sent the terminator back there HAS to be the time line in existence somewhere where there was no terminator or kyle reese,but there still has to be a john o conner.

The only way time travel really works in this or any other situation is to think of many histories/many universes,so theres not just one time line getting interferred with.

So you can go back and kill your grandfather so long as youre not affecting your existence,in the case of many histories/parallel universes you wont be cos theres universes where you dont exist anyway,theres universes where your grandfather dont exist,so long as this is the case there shouldnt be a problem with time travel,otherwise in a single universe/timeline i find it more than difficult to swallow.

[Nuradnan]

Let us say that Time Travel is possible. But, Mr. Time Traveller is moving "forward" in time when he do it. He just "arrives" at his "past-date", not his "past-time".

Okay, I must wake up now.

[jimmy]

To last post incorporate music to "Twilight Zone".

[Matthew]

Could it be that all time is interrealated. And what happens in the future affects our past, and present.

[damienpaul]

Like a time loop, matthew?

I have heard of time loop theories before, but not much and not recently, perhaps someone can elaborate on it for me.

[Faulkner]

Past is only just a memory, and future is our imagination....

That&#39;s quite profound, Littlemews. It implies that our concepts of time are completely illusionary, there is only "now"&#33;

I have often wondered if "time" is real or a fabrication we&#39;ve created in our heads...reinforced by our seeming OBSESSION with the ticking of artificial seconds in a mechanical clock...just look at how regulated society makes itself...everything on schedule, deadlines to meet, alarm clocks set to get up for work... This obsessive self-regulation, surely there&#39;s something pathological about it??

[Faulkner]

Maybe time travel is real? Check out this news story&#33; :blink:

Some time in the future an insane scientist goes back in time to kill his own grandmother, but how can he had existed to go back and kill his grandmother if she had already been killed?
Makes me wonder if time travel is even possible in theory or fact.

look, i am new one here...
i work in a special secret time travel department - i am the maneger of the expiriments to time travel.
if you know some stuff that can help me, please telll that to me.
my email is: dima2003k@yahoo.com

1. what you said now is a real paradox.
2. i think when someone travel in time the universe redoubeling it self
and this somone get to the present of the ather diamention.
the place he left stay as it was&#33;

thank you for reading this.

I all aprecciate your responses and quite amazed of the theories of some of you have come up with.
They have given me a new view on the whole issue, anyway heres is another interresting theori that I saw on a space/time travel program (discovery science).

This theori includes the possibilty of multiverses excisting in order for the theori to work.
You may travel back in time and change history, but as soon as you travel back in a timeline you will end up being trapped in a parallel universe where history is different and cannot return to your&#39;s since you are trapped in that one.
Which may mean that there are time travellers here but are trapped in this universe in the past or future timeline and can&#39;t return to their universe.
This leaved the fact that there are universes where parallel selves have been erased, but exist multiplically in one universe but scattered between timelines.

Interresting eh

[Hoore500]

What I don&#39;t understand about this whole theory of travelling back in time is that following my own insight you need information to reconstruct things of the past, and universe has no memory, so how can you go to the past? Unless maybe if you couple a time machine to a computer that has the information in it.
I suppose this is no very physical way of reasoning, but I&#39;m reading about the subject till I understand it. I study black holes and time theories, but till now I only understand you can travel to the future, nothing is as easy as that in fact: get into your bed and sleep for a hundred years and you awake as many years further in the future.
