What do you think? Is it possible? Will it become available soon? Post your thoughts here.

I pinned this topic because since it is the Time Travel Forum I think the question, Does Time Travel Exist, will be a very popular topic.

I think time travel exists way into the future where they just use a machine, like a teleporter.

I don't think it exists. Just my opinion though.

Time travel will be possible, but only to 3 people and for only 3 trips. After 3 trips, the time machine will be destroyed by the force of time, stranding the people in that time. Why 3 people? Because there's only room for 3, and you need one to steer, one to generate the power (sorry guys, no gas in my time machine. just an exercise bike), and one to keep the time fluids (chemical flux capacitator, not electrical) in ballence.

Time is precious and cannot be wasted, so therefore time travel must be used carefully.

OK, but I don't see what make you think that....

Just a little musing on the blueprints for Time Bike (from The Ride) . . .

Ah! I've never been on the Ride, so I thought you were trying to say that you had built a time machine, but not in the good ol' delorean form.

Wouldn't you like to know . . . :rolleyes: :lol: :lol: :lol:

Hmm are you keeping a secret from us howard? Lol. OK back on topic.

I think time travel is not possible, and if it was we would have to destroy our means of it because it would be way too dangerous and destroy the universe.

Yes. Think of it this way:

Istead of a line, Time keeps overlapping itself. no going back, just overlapping. So there is no possible way for that overlapping to go backward, or forward, and amount of time.

No i don't think that time travel will exist. The word Paradox already proves that time travel cannot be.

Exactly. Might as well change BTTF from a sci fi to a fantasy.

Yes time travel is possible. First you have to consider if other times actually exist outside of this exact moment in time we call the present. From our limited viewpoint it appears that the past is done and the future has yet to be made. My theory is that the past must still exist somewhere otherwise we can't all be here now. Its the necessary foundation of our present and future. The future already exists because its only the future from out viewpoint. Wonder if someone whose origin is in 1955 travels to now. They just traveled to the future that supposedly doesn't exist yet.

The universe is a 4-D hypersphere just as the Earth is a 3-d sphere. A 3-d sphere consists of infinite 2-d circles and a 4-d hypersphere contains infinite 3-d spheres. I like to think that each 3-d sphere is one time increment of frozen time like a frame on a roll of movie film. The entire universe is a 5-d hypersphere that contains infinite 4-d universes that cover every scenario there is. When you travel in time you actually travel to a parallel 4-d universe that is nearly identical since the very act of you time traveling is a change to the timeline. Each change you make causes you to shift to a new universe. Time travel (4-d) is more like 5-d travel. This is the natural state of the universe that prevents paradoxes.

5-d shifting between universes would probably be easier then complete time travel in that all you have to do is change the frequency of your bodies energy waves to push yourself into another universe (your body and all matter in the universe are composed of energy waves).

We already travel into the future at the set rate for the part of this universe because are bodies energy waves are sewn onto the fabric of space-time so we move with it at its natural rate. When we increase our speed to near the speed of light we can travel to the future much quicker. If you could hit the speed of light time would seem to stand still and if you could travel faster than light then you could travel to the past. The later two aren't possible according to modern physics. So from the viewpoint of today's science only travel to the future would be possible through really fast speeds. Perhaps with some future space ship. I think a speed of light or higher would be possible with radical new technologies that would create a hyperspace (non-space/non-time) bubble around a ship allowing it to bypass the physical limitations of space-time and travel FTL. In essence ripping yourself and/or your ship off of the fabric of space/time.

Besides a ship maybe you could make an energy accelerator to change the speed of your bodies and/or ships energy waves. It would be a lot more possible to make energy travel FTL rather then a hunk of metal matter. A full service energy transporter could alter your bodies energy waves to allow complete 4-d time travel and 5-d travel to alternate universes. I think if future genetic engineering can finally allow us to use 100% of our brains and have full access to our sub-conscious minds then our race may evolve into beings that can someday travel anywhere at anytime by just willing it.

Dude, so do you think that humans can fly just by willing it if we use our brains?

Time travel is much harder than flight. Before, humans could not fly, now inventions have allowed us to use a machine to fly. Now, we know by the basic laws of flight that humans cannot fly, because of the force of gravity. Humans do not have wings. They simply cannot will themselves to do something just by thinking it.

Now time travel, if at all possible, will, like time, be made into a machine. But that does not mean we can just will ourselves to time travel, even if we used all our brain power. You cannot do something just by thinking it.

Sorry, but I don't think what you said makes sense.

I think someday thousands or perhaps millions of years from now if we can finally use 100% of our minds and have full sub-conscious control that it might be possible to fly or time travel. We would have 100% control of our bodies down to the smallest level. The energy wave level which is sewn onto the fabric of space-time. Manipulating our own energy waves would enable anyone to move in 3, 4 and even 5 dimensions. A machine would probably be invented first before people could do it on their own. Do you think we are going to keep living lives with basically the same old biological bodies relying on machines to do everything for all eternity? There is no reason why we can't evolve to a higher form someday such as the Q on Star Trek. Otherwise then your saying someday we must say we've gone as far as we can so lets give up.

You are correct. Time Travel is not possible. I watched an Horizon documentary about it. Saying that it was physically impossible to intentionally travel through time. Although, they do say that people are already time travelling as we speak.........................those people, are those that live in SPACE.

OK, if we are able to use 100% of our brains, we could be able to fly. If we have up to the smallest amount of which finger moves where, we could somehow develop a system in which we can move our bodies to make flight. But I still think that time travel is impossible.

I think Time Travel will be possible but it probably won't be invented now. Technology isn't advanced yet to time travel now but probably in the next century it will be possible.

^You seem so certain that it is possible to time travel. You obviousley did not see the 'documentory' about it

If nobody thought outside the box then we wouldn't have the modern technologies of today. Humans aren't going to stop exploring because old physics says you can't go any further. The scientists of the future will have to think outside the box or outside the 4-d universe to break past the barriers of this universe. Perhaps development of a ship inside an artificial man made micro-universe that can travel up to higher dimensions like the 5th and then re-enter our 4-d universe at any point in time.

Well, I supose if you put it that way. Possibley in the future but I don't think we will be around to see it. Well, our past selves will se it if they come into contact with it. (if they do a test run in the future)

I believe that Time travel will eventually be possible. As time is as much of a dimension as height, width, or length, all that must be discovered is a way to move through it.

^The Fifth Dimension beyond that which is known to man... :D

I have heard the "dimension" thing before. It would be cool to have time travel exist, even if not in my lifetime. At least not in the first timeline of my life. ;) This is assuing time travel exists and that we are not on a fixed timeline.

The way I see it, is that it is not possible.

I believe travelling in the past is possible, but not the future.

The future would mean that our fates have allready been written out. I believe that there is no such that as fate. I do believe that we have the option of traveling into the past though, as it has been written allready.

It is impossible to travel to the past. Don't tell me otherwise because I know and Einstien knows it's true. Now we could possibly go "foward" in time by moving close to the speed of light.
That would make us move so fast the rest of the world is years behind. There is a theory that if we could get in a space ship and go to the nearest black hole (the very outer ring so they won't get sucked in) it would propel the ship so fast that the trip would feel like one year to you but to everyone else it would have been like 75 years in the future. The problem with that is that being propelled at that speed would kill any human being. The force of that speed would crush you against the back of the ship like a pancake.

then whats the point of trying that if your gonna die.
Unless we figured out how to stop you from being thrown into the back of the ship then that idea is useless :P

It is interesting that ever since Einstein showed it was theoretically possible, the quest to travel through time has drawn eccentric amateurs and brilliant scientists in almost equal numbers. The amateurs include Aage Nost, who demonstrates his time machine in front of the cameras. The professionals include the likes of Professor Frank Tipler of Tulane University. His time machine sounds good - but it would weigh half the mass of the galaxy.



There is, however, one way that time travel to the past could be possible. And it would be much more convenient. Future civilisations could use computers to create exact replicas of the past. Unfortunately that idea has physics trembling in its socks. Because if you can generate a perfect virtual reality version of the past, who's to say we are not one of the replicas?

We are just in the extreme beginging stages of understanding the relm of physics. Just look at how far we've came in the last century. Once we actually realize that we can't be bound by our current system of physical laws, we can start to think about something such as time travel and faster-than-light speeds.

If a 5-d universe is the truth of the matter, then there are truely no time travel paradoxes because every possible universe including the ones you would create by going back in time and changeing things would already be in existance and you would simply (maybe simply is not the best adjective) be traveling to that universe.

There are truely so many different aspects to every little thing that could posibly be talked about that I can't even begin to explain a single thing without leaving a ton of "stuff" out.

Can someone else help me out here? :martyjr:

Well, my personal opinion is that it's not possible, if it were possible to travel to the past then wouldn't someone have come back and told us? If traveling into the future were possible, we'd be traveling into some place that does not yet exist.

Personally, I think that if it were possible then just as Doc quotes, "Time travelling is much too dangerous", who knows what could happen? Someone could go to the past and bring Hitler to our time, or anything like that. The way I see it is that we would be much happier not being able to.

Another thing is that wouldn't time traveling into another universe go against the scientific theory of the big bang, and the universe expanding? Unless these universes were to collide with eachother, in which case, we'd probably all be in trouble.

Hope this was what you were looking for as help Comp ;)

No one really has a grasp on what time is exactly. Many people believe that time is shapped like a sine wave (/\/\/\/) and in order to travel to another time you would cut across to the other previous wave (/\/\-/\/ the - is the path).

This seems unlikely, but who really knows.?

My take on this is the whole speed-of light thing: as the speed of light is aproched, time starts moving slower for you than the rest of the universe. This means that near the speed of light, you are traveling through 1 second of time much "faster" than the rest of the universe. This also means that as you go past the speed of light, time would actually reverse and you would travel back in time.

The way that this can possibly be related to most conceptual time-travel devices (the DeLorean included) is that a sudden surge of energy (1.21 gigawatts in BTTF) causes an instant warp to the speed that would cause travel to the desired time period. The surge would cause greater or lesser time transfer depending on the way the system deals with and manipulates this surge.

As you can see, this is all theoretical, but I believe that is the basic idea. This seems like it should be possible; the only problem is finding the way the manipulate that surge to produce the desired effect (time travel in this case).

Pretty pretty good for my 7th post, eh? This is a great forum. :martyjr:

i have three ideas...

first of all, i think it could be possible because every tiny increment of time is called a now, and every time u make a decision it creates another universe. time traveling would be traveling between nows and between universes. if u made a decision to change the space time continuum, you would create a new universe and be stuck in the new one. so that makes me think its possible.

well, you know paradoxes are impossible. like the one where the old man goes back in time and kills his younger self. therefore he would be dead and not be there to kill his younger self. this is a paradox, and it is impossible. therefore time traveling is impossible.

but then again, ppl time travel all the time! thats what time zones are for!!!

That's an interesting theory. But by the same token, what stops us existing as part of another being's dream? Or part of a computer program to find questions and answers?

Anything is possible..and the (wo)man that finds the truth will be immortal and rich.

I've just found this topic!

Here are my thoughts on a few previous postings, such as they are...

TheJoker said..

There are plenty of theories for time travel which do not result in a paradox

TimeTraveller said...

What? While you are true in saying that all matter can be seen as energy waves, the frequency of a particle is directly proportional to it's mass multiplied by it's speed. If your car accellerates, it's overall frequency will increase, but it will not be pushed into a parallel universe.

TimeTraveller also said...

As far as I'm aware, there's nothing in modern physics that states that it's impossible to travel faster than the speed of light. The problem is that the energy required to accellerate a mass rises exponentially, with the asymptote being at the speed of light, so in order to reach the speed of light, you'd need infinite energy. But, if something is already travelling faster than the speed of light, or if something has no mass, then I believe that it's possible.
But basically, any time-machine theories which involve acceleration to beyond the speed of light wouldn't work.

TimeTraveller also said...

The 'fact' about us only using 10% of our brains is a complete fallacy. Activity has been measured in all areas of our brain. Most of this activity is either subconscious or unconscious, but it's still being used.

There is nothing to stop time travel to the future. As superng stated, you simply have to jump into a spacecraft and fly around really really fast. When you return to Earth, time will have passed quicker for everyone else, and so you will be in the future.
In order for this to be noticable, you will have to travel at unbelievabe speeds for some time, but it is possible. The trip will be a continuous journey, you will not 'jump' into the future. And there will be no way back.

This time-slowing effect is caused by a warping of space-time. Space-time is also warped by gravity, so in areas of space with strong gravity, such as near black holes, time-slowing effects are also noticed. But black holes are really really dangerous. And there are none nearby. :)

There is a paper here...
http://arxiv.org/abs/quant-ph/0506027
...which proposes a theory on how time travel to the past might be possible without creating paradoxes. The paper doesn't suggest how someone might be sent back in time, it just theorises how quantum physics could prevent paradoxes taking place.

Phew! Glad I got all that off my chest.
:)

As much as I like the idea, it will NEVER happen! :D :lol:

What you mean like in Men In Black 2where they open a door and the whole universe is inside a train locker?? Interesting, well I'm open to the idea.
