:bugeye: I belive time travel is possible and the reason we dont see time travelers is because the future is not certain yet. anything can happen between now and 500 years from now. one day when it is possible people would more than likely not be able to go back and forth all willy nilly. when people did go through the only other people that would know about it would be the cranks an weirdos because the people of the future would want to see the reaction from other people towards them, I wouldnt want to tell someone important because they would simply have me instatutionalized at the slightest mention of it. feel free to dissagree with me. I would love to have your opinions
on the matter.:bugeye:
 
No the reason we dont see time travellers is

A)there using a wormhole so you cannot go back before the creation of the wormhole,as we have not made a wormhole portal through time yet,we can quiet safely say no one can come back to this time.

b)maybe they have but they disguise themselves,pretend to be ghosts,goblins,angels,demons etc or they are percieved as such

c)Quantum theory's suggest that when you go back in time youre not in the same universe your in a counterpart quantum system which is the same in every way except you are there,the other universe still exists but is now without you as youve gone in the quantum counterpart,this means you can kill your grandfather,no paradoxes,this is the most likely situation.

It means any time travellers who do come here are not from our universe.
 
i see.

:D thank you for your opinion i formed this idea last night around three while listening to stephen Hawkings talk about time travel.
 
Is there really anything useful in time travelling?

Relativity forbids (if i remember correctly) travelling back into time because of paradoxes and the issues of causality, but not the other way around.

The time traveller would want to return to his life after the "trip"...but relativity states that once you travel away from your origin planet you no longer are in the same reference frame as the origin planet and time can (and does) elapse at different speeds for you and the planet. So if you take a "trip" you would return back to your origin planet in the future and perhaps your civilization may be extinct by then.

Or something like that.

Oh relativity allows forward travel,without a doubt,your second paragraph is about right,you leave earth torwards the speed of light and youll only age (or time will pass for you slower relative to earth) maybe a year,youll get back and 20 years might have passed.


As for backwards travel im not sure special releativity forbids it,i think einstien fudged some equations.

Basically paradoxes would only be the case if you dont believe the many worlds interpretation of quantum physics,i think at a quantum level either way time travel shouldnt be an issue but in classical terms its a worry incase people go and kill there granfather before his grandpa had sex with grandma,bit of a key problem,although its NOT a physics problem with time travel,its a logical problem.

Theres not much in physics that says you cant go back in time its just very difficult,youll be using black holes,space craft and all sorts of things to make wormholes which might not be invented for....well NEVER probably,
thats not the point though,the point is to eventually prove its possible,not that we might one day be able to do it,it is taken serious,it is a serious area scientists study esp in theoretical physics.

People MUST understand that nobody can actually give a definate answer when you ask
Is time travel possible?

once you may have got a no, a yes/maybe,
now its just maybe! or "well i dont think so but i cant prove im right"

We just need a straight answer,and so far there has been none,so the purpose of studying it is to get that answer to understand more about the universe,i mean it seems silly we cant answer these questions but its just a fact of life,but in time we will know like we found out you could go to the moon,like the earth is round and orbits the sun and so on.

Have you read his book 'A Brief history of time'? It's quite good, up to a point.

Ive always hated his argument which suggests some force destroys your time machine when you want to go backwards,theres no call for you to reason that at all,also im uncomfortable of the GOD exists overtones,anyone who mildly believes in god is likely to fudge stuff to suit there personal bias,this is one of those examples.In his new book he depicts it as god who blows you up before going backwards,i think its part of his logical sense of humour but i cant be sure what hes implying,he says bolt of radiation but.....huummn

Overall i get the impression hawking mostly ignores the many worlds interpretation of quantum physics/mechanics,and throws in ideas how with a few calculations time travel backwards is impossible,i admit i have personal biases like he does but i dont write books to sell to the public.

Cosmic censorship is what made hawking famous in papers where it all blasted out TIME TRAVEL IMPOSSIBLE,i dont think he meant it that way,but its not as cut and dried as that.

But Doom, I'm sure in his book he says Time Travel is possible.

Nah,no one knows for certain,its all a maybe,and he forced more arguments against it than anyone else as far as theory goes.

I wouldnt worry too much about it,im fairly certain time travel is possible,but i doubt we'll see it in our lifetimes,its just one of those things that is way way way out of reach for centuries to come.

I believe it will be proved possible/impossible in our lifetime though.
 
I've heard that the laws of physics will only let us view the past in another dimension without them seeing us. Going into the future is pretty easy, all you need is a lot of speed.

Ive not heard that exactly,although i will say that i believe backwards time travel is impossible unless there is a multiverse,im pretty sure there is a multiverse instead of a single universe,theres quiet alot of evidence of this and nothing in the laws of physics would prevent time travel.It also would throw logic problems such as paradoxes away.

If everything is doing everything in all possible states then youre only changing one state of many states.
In a single universe youll be changing everything from there on meaning you came from knowhere.

I dont mind people believing in time travel,but when them same people think it would happen in a single universe ,i just shake my head,that would be ridiculous as soon as youd go back youll be changing things just being there,you might step on a wasp that was about to fly and sting an evil dictator who happened to be allergic to wasp stings who was originally going to die just from that small event,things are the way they are now because of the way they were,alter that and its like you came from knowhere.

So parallel universes/multiverse works cos we can safely say that there are universes where hitler won,elvis didnt die and so on,when you change something youre changing THERE not HERE.

Thats how i see it anyway.
 
studying time travel

that's a very good subject to bring up.
did you watch the movie btw?

try these:
• A Brief History of Time by Stephen Hawking
• Einstein's Law of Gravition by Bertrand Russell
• The Two Masses by Isaac Asimov

if they haven't already been recommended.

personally i would love to time travel but the only time traveling i'll be doing is when i'm dead and traveling as a ghostly spirit.

y'know you can travel out of your body.
Gaugin claimed to have done it. He painted one of his friendly visitors in one of his paintings. Of course he was taking some drugs. haha. no but really you can do it if you wanted, maybe not back in history but travel out of earth and see what is going on in other universes.

i'm doing some research on time traveling right now but i want to read more into it in experience than just texts and famous peoples own experience. We make our own don't we??

By the Light of the Silvery Moon.

Lost in Space-Time, the Reality of the Fourth Dimension, Time Travel is possible but only if you are a licensed, certified Space-Cadet.


:eek:
 
i dont pretend to be an authority on this matter but everyone gets caught up on trying to prove why it cant be true and then working aroudn these to make it possible again,
and the arguments but forward r very indepth and of high calibre but, has anyone thought of how to do it???
surely thats the first logical step, if we are to enter another universe how would u go about that, some event horizon loop?? :) going forward in time is obvious by speeding up your frame of reference but, can u do the opposite of that, to go back in time?? reversing your fram of reference?? we dont go into another universe when moving forward through time, thus when going back in time u could never return to your original universe?? every step back in time would mean a universe further away from the original no matter how far forward in time you went.... theories???

Time does not Travel, the only Time is, Now, this moment in
Space-Time.

Space-Time is a Singularity, these Two are the same Reality, are
of the same source, differing in name only as motion issues forth
as angular moment, as a singularity becomes Two, as Two
become One, continuous, the Reality of the Fourth Dimension.

In the fourth Dimension Time is continuous, constant, Reality as it
Exists at a Given moment in Space-Time, the Here and Now.

Now is the Time, the Reality of the Moment, the Singularity of
Space-Time, the Here and Now, the Reality of the Fourth Dimension.


:eek:
 
The Reality of the Fourth Dimension.

The next step, Dimension, in the Evolution of Time and Space
is the resolution of the Space-Time problem which is Temporal.

The Reality of the Fourth Dimension where all Reality has a physical quality where the Truth of Reality is Absolute.

The Reality of the Fourth Dimension is where the Two become One by adding a third Element, Dimension, between the Two; the Three, Dimensional, spatial coordinates of the Material World of Reality and the Temporal World of Reality causing the Space-Time to be a Continuum, One, a Singularity, as above so below.


:eek:
 
Any thoughts of time travel just seem to be from people finding loop-holes in the laws of physics - no doubt due to something we don't understand yet (in reference to wormholes specifically).
 
Surely the fourth dimenstion does not have to be time itself.....it could (though less likely) be another spatial dimention normal to our three dimensions.

I agree that we have not yet found something critical to answer this question, but perhap the reason we have not yet found the solution is because it does not exist.

And, I think backward time travel is a nonissue

1) too many paradoxes

2) If you are to eliminate the paradoxes the time travelerer cannot in any way interfere with the past and therefore the usefulness of the trip is not there.
a) Well maybe for high school history classes
 
The Fourth Dimension of Reality does exist within, right along beside, the three-dimensional World of Reality.

Space-Time is a Singularity, the Space Time problem is the
differentiation of Time, the Space-Time problem is Temporal, is of the Fourth Dimension, another spatial dimension, Zone, the Twilight Zone.

Paradoxes are a non issue if the many worlds interpretation of quantum mechanics is correct and theres good evidence to suggest thats the case,thats how things work,though not for certain yet.
In this way we can go back in time because backwards is like a hall of mirrors while forward is just one mirror if you catch my drift.
