(Yes, I'm sure there is more topics on this, but the older ones are poitnless, naturally)

So, who here believes that we will be able to time travel, and when?

Using the Flux Capaticator we can easily achie... ok, so Back To The Future isn't exactly accurate.

But, any ideas, on which if you had the resources, you think we could accomplish time travel?

Time travel is not possible because time is invariant. It does not flow in any direction. You cannot travel to the past because it is not an actual location. However, time travel may be possible on the quantum level. Or a form of space travel.

That, IMO, is "in the box" thinking. We cant be sure at all that it isnt an actual location. I will suspend making a decision on it either way.

^I was pretty "out the box" too

Time travel woudn't be possible, if you kill you father 10 years before you where born, will you fade from existacne? I believe that we mealy change demenshions, so that if yopu killed you father there you would not exist in that posisble out come.

and you need to travel faster than the speed of light, we'll know when we nearly have it when a order for 500 monkeys is put in by the government

Some particles can "move backward in time". So it's feasible (or not) if a quantum computer were created to transfer particles to another time. Also, if you go in a black hole, it's a possible form of time travel, depending on the singularity. You can either go into another universe, or another time and place within this universe.

I support Yelekiah this time. He's a bit right, you know. I voted never.

Or when reaching the quantum singularity you could be massed into a stream of atoms then turned into pure energy, (I rather not time travel)

plus the amount of gravity you would need to sheild your self from

and that the gases near the center are about 50000C

and that theres no way of enshureing the time upon where you exit

i think re directed wrom holes wold work

living tissure being seperated by atom isn't good

Now that you mention it, you might just get shredded going into a black hole. So good luck with that.
Physical time travel, in my opinion, is impossible based on the characteristics of time itself.

of course i know enough about them just check out my blog

I think I commented on it before you posted this lol. How weird.

I always hear about that, but is there even much evidence to support it?

No, it's purely hypothetical since we have yet to approach a black hole.

I voted a thousand yrs, because you never know?

When we are talking about black holes are'nt we talking about travelling to a different place in time. not to another time altogether.

Or a different universe (could be in the same time).

Yelekiah, you and I touched on the tip of this iceberg a little while ago. I think we both agree that "time" travel is a misnomer, that it's actually manipulating "time" by altering distance.
Given that we must find a way to get beyond being limited by the speed of light, I think it's a matter of "standing on the shoulders of giants" again and again until we reach the capability.

with all things possible, i believe that time travel can be achieved ~ either within, or in the use of technology developed specifically for it.. time is moving elusively in a singular motion, but i seldom ask myself why, nor do i delve into its function often...but if i start to think about it more, then i can preceive time & how motion gives hint to its existence......but if time exists, whose to say & claim that its flow is the only constant? if one can understand the other elements associated with time, then time becomes playable like a dvd ~ with possibility of traveling to any point..

lol, that was spontaneous.. this kinda reminds me of empire strikes back when luke was astonished to see yoda levitate his transport from the waters to land...luke tells yoda that he didn't believe it, & yoda returns ~ that, is why you fail.. forget doubt, if one truly desires to travel through time ~ just go & develop the means...only doubt holds us back from anything we dream to do.. ramble, rumble does creativity flow like a river's course to the open seas..

so i vote yes to then, now & to be......but not government related, of course..

Well actually sound, under certain circumstances, can travel faster than the speed of light. But so far, it's still a physical impossibility.

Say you traveled back in time to before the universe began. What would happen to you? I think it could be possible but the universe would have to be infinite and never have a beginning or end because how can you travel into time to a point where nothing existed?

truly, a valid point...if there was a beginning, surely there would have to be something before the beginning? perhaps the end of something else that once existed, or that led up to the beginning of what leads up to now.. if numbers are infinite, then i would like to think that perhaps something existed before what we perceive as the beginning.. otherwise, paradox should anyone actually succeed in traveling there..

I believe the idea is that is it possible to travel between two different 'times', one at each end of a black hole (or wormhole, in my case). Here's how it works:

Suppose you open a wormhole in space (if it is possible, which is dubious, since all the wormhole models require large amounts of negative mass-energy). You then stick one end of the wormhole on a spaceship traveling at nearly the speed of light. Since, relative to an outside observer, time is passing slower on the spacecraft than at the other end of the wormhole back on Earth, the spaceship is 'behind' in time. It's not exactly the most desired form of time machine, though.

Not the most desired since wormholes are extremely unstable.

I pointed that out. My time machine was based on the assumption that one is actually successful in creating a stable wormhole.

I think Yelekiah said it best when he mentioned that certain particles already travel backwards in time. Time is relative to the observer. I'm not sure if time travel in the sense that is being talked about here or in the movies is at all possible. Even if one were to get in a ship and go "Back" in time on it's universe's time arrow, they would still at least be going "Forward" to some degree on their own time arrow. Maybe the universe/God adjusts itself and realizes those people aren't supposed to exist at that moment and thus they die when they try to emerge! Perhaps that's why we never see any time travelers And going back before the creation of the universe to me seems like "swimming outside of the pool"... just isn't possible and doesn't even make sense. A person traveling back in time really just isn't plausible becuase their own arrow is still moving forward (they can't avoid death). People going forward in time is different, though. And nobody is going to last through a black hole.

As for faster than light travel... doesn't greater acceleration require greater energy consumption? For us to travel faster than the speed of light essentially requires the energy equivalent of the universe, I thought. Thus it's impossible. I can't remember... relativity is wacky.

Hello I just signed up to the site. I have reading alot of the info on here. Decided maybe I would start throwing some of my ideas out there. Well I dont think time travel exist matter a fact I dont even thing times real since it was created based on the movement of this galaxy the plants, the sun, the moon. So if something was different say we had another sun or moon. Then the whole consepte of time would been different. Like for example if we lived in another galaxy that had a different orbital movement would time still be how it is now. When you think about this think back when they first made up time it wouldnt be the same. In my opinion time is just like relgion made up to keep the masses in check. I dont know came up with this whole theory one night when I couldnt sleep. I also think as soon as we get around this we can really figure out more about the universe. Im just going to stop ranting now. I dont mean to upset anybody about my comments.

Why isn't there an Unsure, or I don't know, option? That'd be my answer.

But for the sake of argument, I am leaning towards the Never choice, as we'd have people traveling back in time today if this were the case. SO that's what I voted.

Regards, PA

*sigh* Not again. The very fact that something was moving proves that time exists!

How does that prove time exist, if it does exist how do we know we got it right. If I remeber right wasnt like every civilizations calender different in some small way.

Exactly, time was envented by humans, and it was envented diferantly acording to the people. The Pegans used a calender based on the moon, and had 12 Moonths, yet it only equalled 354 and 1/2 days. Egyptions used s calender with 12 months of 30 days each with 5 days part of no month, finally the Chineise calculated the length of the year to be 365 and 1/4 days. the Greeks barowed this and made the calender we know today. So as you see, time can be anything, aliens could have a googlefarcle and have it last 2.48213 seconds, time is relavent and will always be.

This is from Wikipedia.

Time travel is the concept of moving forward and backward to different points in time, much as we do through space. It also includes traveling sideways in time between parallel realities or universes.

A few years ago, my BF & I went on holiday to Florida, this took almost 8 hours of travel time, we had taken off on Friday morning around 11am (GMT) and arrived in Orlando early that morning on the same day (hope I am not confusing anyone lol)

Florida is 5-6 hours behind us here in Ireland (depending on the time of year) and shortly after we had landed, my BF laughed when I said, it's time for breakfast on this bright Friday afternoon (it was 2pm)
for a laugh I added - "We have just travelled back in time"!! he just laughed at me again, as he was tired from such a long flight as he had never taken one that lasted so long before, he thought it was at least 7pm that same evening. When I had pointed a few things out (after a few black coffees ) he looked at me and said - "Wow it is only after 2pm here, to think that we left home at 11am and its taken us 8 hours of travel and its only gone past 2pm"!!
The whole thing seemed as though we had travelled back in time, when we had just entered a different time zone, which was a pain in the arse when we went to call home and our family complained as to why we where calling so late, we kept forgetting they where 5 hours or so ahead of us.

As for being able to travel back and forth in time, to different weeks, months & years, that I am afraid is impossible and will never happen IMO!

Don’t take this the wrong way as I am just curious and I would like to find out more so…
How do you know they are unstable? Aren’t wormholes just a theory? Has anyone ever seen a wormhole or where it leads to?

About the speed of light…

It is impossible to travel faster than light
One day we might get close to light speed, but we will never pass light speed, by the conventional ideas of moving forward, but there could be a way around it.

Is the concept of faster than light speed travel in Star Trek plausible or are they just blowing smoke up our backsides?!!

Worm hole could work but to be shuire where you come out you need to harness the power of a galaxy. But using a regular one and having it close on you would produce a time flux, sending you to every possible time in the universe, except, you become a stream of atoms.

But my question was...aren't wormholes just a theroy??? I mean no one has ever seen one!!

True, but we have detected strong gravatational feilds appering and then disappering rapidly.

There are also wormholes at the quantum level.

Very true.

Oh and that a worm hole to transport a potato chip without having it ripped apart by the gravity is truely incredable, 1,000,000,000x times the size you want to trans port.

Potato chip = a wromhole the size of jupiter.

I believe time travel is possible and I do think that quantum physics may hold the key. For instance Entanglement a process of quantum that enables particles to impart info regardless of distance. It is this property that scientists NOW are using to develope Teleportation like in star trek. However using normal supercomputers of today are not upto the job of holdiong all that dissambled data only a quantum computer will as it can hold more numbers than there is atoms in the entire universe. Using This teleportation we will be able to send objects and possibly people through vasts distances in the blink of an eye (so to speak).

However theres another property of quantum called nonlocality in which time does not play a part. At the quantum level a particle is able to give its information to another regardless of "Time". That other particle can be in the paast or future it makes no difference.
If we can manipulate the nonlocality like the entanglement and send info to another time frame then you have built your time machine. Sounds simple and it probably is but untill we know more of the universe and have a bigger comprehension it will be at least a few hundred years before that will happen. there needs to be a dramatic change in our civilisation and the way we think before we can even consider putting it on paper for real.

Consider this if one country as they stand today had a time machine you can bet your life that there is going to be extreme tension by those countries not having one and quite possibly a war will follow . Why? Well no country will have a secure history in their minds as who knows what endeavors the timetravelling country has taken as their can literally change ones countries history and who is going to feel secure in the knowledge of that?

Yes, but ripping a human apart atom by atom, will require you to reanimate it somehow, we would be able to teleport items but not living things without having them come out dead.

Wait, how exactly did you come about this?

PEACE

I don't believe that this world will last after 2012...

Physics.

Why? That whole asteroid thing?

Earth is extremely tiny compared to the universe in whole, the odds of an asteroid hitting us is very small, although it's not impossible, just improbable.

If it is possible to travel in time. (I don't think it is, but what do I know?) I believe what is said in "A hitchhikers guide to the galaxy" Even though I believed the same before I read the book

No matter how much you try to change the past, it has all happened before/now. And it will all just fit together like a big puzzle.

I did not vote because the direction of time travel was not specified. We can go forwards in time already now (very little) but we will never go backwards in time.

Time Traveling is possible and i`m realy shure that people already has traveled in time ! Also if no one never had traveled in time then maybe...: dinosaurs still would live, John.F.Kennedy was still alive (old, but still alive), the Germans won WW2... With other words: the world would be a total caos.

Time travel to the past is so far impossible.

I would have said no given that the past is not a location. The fact that time doesn't flow in any direction would make it difficult to go to a specific "time". It's invariant to begin with.
