TIME travel?....not impossible, just highly unprobable

[xplosive_cooker88]

So what do all y'all think about time travel?

[PhonePhrack]

if we can make something faster than light speed i think it is possible

[itismesaj]

I follow determinism, where each action is a direct response to the action before it. That said, time travel would be possible because at any one time there is only one plane of time (the future).

[xplosive_cooker88]

true hacker....time slows down the more you reach the speed of light and so if you could go the speed of light everything would seem frozen..but yes...if you were to excede the speed of light then you could possibly go back into time

[itismesaj]

No, not the past, but the future. If it were possible to go to the past, we would be feeling the effects of it right now.

[xplosive_cooker88]

true and say that a time machine is made, then in the future the farthest back in time that we could go would be to the time that that particular time machine was made

[xplosive_cooker88]

so what does anyone know about the fouth dimension?

[exial]

why...one thing u cant cheat and cant manipulate is "TIME"
get used to it..stop trying to change what obviously cant be changed..gods show superiority over one thing DEATH.
u cant cheat death, u can prolong it but cant cheat it..
get used to it.

[exial]

fourth dimension..hmm more like counteless dimensions..
we are barely scraping the surface when we talk about fourth demention..we have to look beyond the physical...
but of course we cant comprehend what we dont see touch or at least have some fucking facts about.. we can barely comprehend that theres worlds(life) outside of this one..
hmm life is strange. a test in more ways than u would believe.

[exial]

cooker wat do u know about the fourth dimension?

[A Deo et Rege]

The thing about traveling faster that the speed of light is that according to Einstein it is impossible because once you reach the speed of light your mass would become infinite, which is impossible or highly improbable. Travel is possible to the future because that is the direction in which time normally flows, and the faster you move the more slowly time moves relative to you; they proved this with the atomic clock experiment (Google it). Travel to the past is a bit more complicated; the "easiest" way to travel back in time would be to go faster than the speed of light, but you run into the previously stated problem; However, if you were traveling a 99.99999999% the speed of light, which is a feat within itself, and while travelling at this speed jettisoned a craft from the nose of your ship it would force it past the speed of light which would "theoretically" bypass Einsteins aforementioned problem. Does that help?:confused:

[bluddspun]

if an object is traveling at the speed of light, and it shines a flashlight in the opposite direction, does the wave of light hold it's place? I know that sounds off topic, but speed is all relative, so if I am sitting down here, and someone whizzes past my window at the speed of light, to them I am moving in the opposite direction at the speed of light. I'm just trying to figure out if maybe lightspeed is relative to the center of the universe, because motion is relative, if someone could maybe clear this up because my ignorant self doesn't see any correlation to how fast you are moving relative to another object and your position in linear time...

[PhonePhrack]

EXPERIMENT:

Car
Hose

Hold the hose out the window of the car
travel the speed of the water to come out of the hose
turn the hose on...........
what happenes?
same with backwards

[bluddspun]

okay, but the direction of the water depends on the angle of the hose. I guess my question now is, is it possible that two parallel beams of light, moving in the same direction, could be moving at two different speeds??

[A Deo et Rege]

okay, but the direction of the water depends on the angle of the hose. I guess my question now is, is it possible that two parallel beams of light, moving in the same direction, could be moving at two different speeds??

No, because the speed of light is a constant and can't be changed.

[bluddspun]

constant, okay, I don't fully understand this concept I guess, because speed has to be relative to something.

If someone were to, as you put it, whizz past your window at the speed of light, you for one thing would not be able to see them, but to them you would be standing still because time, in theory, stops relative to the object moving at the speed of light. You would not be moving in the other direction at the speed of light because that would require him to be traveling twice the speed of light which is impossible.

[bluddspun]

oh my god that's fucken crazy, wow that really changes my perspective on things...

[A Deo et Rege]

constant, okay, I don't fully understand this concept I guess, because speed has to be relative to something.

It is, time, speed is relative to time in the aspect that the faster a person travels the slower time passes relative to that person.

I think my reasoning is correct, but I will do some research and see if I cannot enlighten you.

[bluddspun]

that's odd to even think about, I'm totally tripping out right now at these new concepts.. so time and speed are linked, but more than that they are the same exact thing. So this means that time isn't exactly like a fourth dimention, it is more like a bending of all of the other dimentions...which in a way I guess is like a fourth dimension. but basically time and motion are zero and one hundred on a percentage scale; if you are on one end, the concept defined by the other end is not moving at all. but then how is it that an object traveling at the speed of light can still be seen by objects not traveling at the speed of light??

[bluddspun]

I think my reasoning is correct, but I will do some research and see if I cannot enlighten you.
thankyou, Deo

[A Deo et Rege]

They are not the same thing but they are linked; The 4th dimension, Time, is the dimension through which all matter travels; Light, however, is a ripple of the fifth dimension, I could try to explain that but it would take too much time. I also have a sort of "brain teaser" for you to think about\/\/

There are an infinite number of positions defined by any finite movement.
Let movement from one position to the next be called an 'act'.
An infinite number of acts cannot be completed in a finite amount of time.
An infinite number of acts cannot even be started.
Thus movement cannot be started or completed.
Movement is an illusion.

[bluddspun]

thankyou.

this is a bit of a stretch on the topic of science, but I wonder if a chakra "spinning" at the speed of light might cause one to "travel" at the speed of light...

[A Deo et Rege]

I don't know the physical properties of "chakra" or chi, but if you could some how envelope yourself in chakra or chi, yes-maybe, I don't see why not, but yet again I am flying blind when I say this.

[itismesaj]

Time-traveling into the future is not impossible, at least relative time-travel.

Traveling at the speed of light, if you had two flashlights on either side of your hull, and you had the both blinking simultaneously, people viewing this light from behind would see the blink rapidly, but the people in front of you, it would only blink once. Because you are constantly keeping up with light, the people behind you would be living at a different time than the people in front of you, relatively of course.

This throws into perspective some wild thoughts, including what is time? Is it merely man's way of recording events? Or is it allowing events to occur? Most people believe the latter.

[bluddspun]

yeah I guess it is anyone's guess there..

it stands that this moment right now is the only one that IS, and all other moments are standing still infront of and behind this one, but because our brain works in patterns, we see events in a linear perspective rather than in the perspective of possibility. As you said, there are an infinite number of positions in any given moment, which means that we must be choosing which one we accept as reality. But then again, there is that pesky brain that has this strange thing called "memory," which is really our way of filtering out all of these possibilities.. maybe there is some way of transcending this, some way of allowing ourselves to accept these possibilities.

what if we don't see it as "traveling"? you could say that right now we are all traveling into the future because we are moving along this linear plane of time, but in each moment we accept that the past is the past. so yeah, I would completely agree with that latter.

[SuperSkunk]

I heard theoretically if you move faster than light go up to the moon at that speed and look back and you will see your self coming to the moon or something like that.

[itismesaj]

If it were possible, yeah it'd happen. But traveling faster than the speed of light (according to Einstein) is impossible.

I watched a video today that completely changed my view of thinking. It stated that time travel was only possible in post 4th-dimension, because we exist from time frame to time frame.

[xplosive_cooker88]

read this one book called the fourth dimension...its got some really fucking tripping concepts about it. and it compares the 2nd dimension to the 3rd so as you can grasp a concept for the 4th dimension.

[xplosive_cooker88]

Has anyone heard of the concept that plato came up w/? the one about the prisoners in the cave that are chained down so that they can't move anything and they are up against a was so that the only thing they see are their shadows up against the wall their looking at and this is all they know so that they think that they are 2-D figures but in reality they are 3-D and plato compares this to us in 3rd dimension and that the fourth dimension is all around us.....and this is true if you get the concept that you take a "theoretical" 2-D person. their line of sight is basically a line segment, now you take that into consideration and apply that to us and well imagine if a 3-D
figure fell through a 2-D world...the 2-D person could only see
"cross sections" of the 3-D figure as they fell right through....and you apply that to us 3-D beings and try to imagine a 4-D figure and thats when things get complicated to explain.....someone w/ some intellect tell me if this has made any sense

[A Deo et Rege]

Your spelling is deplorable, but let me see if I can't decipher any discernible meaning; 2-D means an object has both width and height; however, 3-D means an object has width, height, and depth; Furthermore, the forth dimension, time, is divided into three categories: past, present, and future; The fourth dimension is the reality in which we live-the present is just a snapshot of time, the past is a closed door in reality that, in normal circumstances, is lock but can be forced open with the proper "tools," the future is the road on which reality travels, it has speed limits just like normal roads except the speed limits are defined by physics, at normal speed we'll progress into the future at the normal rate, but raise the speed and the progress is accelerated, to a certain extent-when you reach the speed of light, theoretically, time stops; However, there is a loop hole, in theory, to surpass the speed of light its called a wormhole, which would instantaneously transport you to any point in the galaxy which according to Einstein is impossible because it would require going faster than the speed of light which is a constant and cannot be surpassed; You could travel trillions of miles in a blink of the eye which in itself would be time travel.

P.S. I don't know if this helped but I think you should read the book The 10th dimension and Beyond.

Time Travel and Religion

Prophecy and theology

It is interesting to note that any religion which postulates the existence of fulfilled prophecy requires, at the very least, an agent which can move information from the future into the past.

In Christian theology, for example, God is assumed to exist unbound by space or time. Doctrinally, God is held to be omniscient and omnipresent. Statements in the Bible such as Jesus's claim "before Abraham was born, I am" (John 8:58) and Peter's claim "[Jesus] was chosen before the creation of the world" (1 Peter 1:20) (assuming the creation of the world began at t = 0) imply that God does not occupy the same ti***ine that we do. This is further supported by the assertion "I the LORD do not change" (Malachi 3:6), since change requires movement along, and constrained by, a temporal continuum.

Two popular interpretations of these statements are that God exists outside the space-time continuum; or exists at every point in space-time simultaneously. In either case, God can transfer information from one point in space-time to any other point without restriction.

Transcending time through ancient wisdom

The Yoga Sutras of Patanjali have been considered by some, such as physicist Fred Alan Wolf in his book, The Yoga of Time Travel to describe an inner process by which we can access knowledge of the past and future in the present. This form of time travel can be acquired by transcending the five Earthly anchors of the ego mind which otherwise leave us locked into the illusory self.

Time Travel
http://www.crystalinks.com/blackholetime.jpg

Time travel is the concept of traveling forward and backward to different points in time, much as we do through space.

Unsolved problems in physics: Is time travel theoretically possible? Is it practically possible? If so, what are we to make of the time travel paradoxes, such as going back in time and killing one's own grandfather, etc.?

Humans are in fact always traveling in time � in a linear fashion, from the present to the immediate future, inexorably, until death.

Some theories are predicated on the fact that we move forward in time, and both forward and backward in space. Since time and space have been shown to be intrinsically linked, travelling forwards and backwards through time is not a theoretical impossibility.

Currently, traveling at speeds approaching the speed of light can cause time dilation, the effects of which cause the individual traveling to pass through time more slowly. From the perspective of the traveler, external time would be going much faster, causing the traveler, upon stopping, to arrive at a place farther in the future.

Often it is a plot device used in science fiction and many movies and television shows to set a character in a particular time not their own, and explore the character's interaction with the people and technology of that time - as a kind of culture shock.

Other ramifications explored are change and reactions to it, parallel universes, and alternative history where some little event took place or didn't take place, but causes large changes in the future.

In physics, the concept of time travel has been often used to examine the consequences of physical theories such as special relativity, general relativity and quantum mechanics.

There is no experimental evidence of time travel, and it is not even well understood whether (let alone how) the current physical theories permit any kind of time travel. Although theories do exist about the possiblity of folding time to hop from one point to another.

Physics

Einstein's Special Theory of Relativity (and, by extension, the General Theory) very explicitly permits a kind of time dilation that would ordinarily be called time travel. The theory holds that, relative to a stationary observer, time appears to pass more slowly for faster-moving bodies: for example, a moving clock will appear to run slow; as a clock approaches the speed of light its hands will appear to nearly stop moving. However, this effect allows "time travel" only toward the future: never backward. It is not typical of science fiction, and there is little doubt surrounding its existence; "time travel" will hereafter refer to travel with some degree of freedom into the past or future.

Many in the scientific community believe that time travel is highly unlikely. This belief is largely due to Occam's Razor. Any theory which would allow time travel would require that issues of causality be resolved. What happens if you try to go back in time and kill your grandfather. Also, in the absence of any experimental evidence that time travel exists, it is theoretically simpler to assume that it does not happen. Indeed, Stephen Hawking once suggested that the absence of tourists from the future constitutes a strong argument against the existence of time travel - a variant of the Fermi paradox, with time travelers instead of alien visitors. However, assuming that time travel cannot happen is also interesting to physicists because it opens up the question of why and what physical laws exist to prevent time travel from occurring.

[A Deo et Rege]

The equivalence of time travel and faster-than-light travel

First of all, if one is able to move information from one point to another faster than light, then according to special relativity, there will be an observer who sees this information transfer as allowing information to travel into the past.

The General Theory of Relativity extends the Special Theory to cover gravity. It does this by postulating that matter "curves" the space in its vicinity. But under relativity, properties of space are fairly interchangeable with properties of time, depending on one's perspective, so that a curved path through space can wind up being a curved path through time. In moderate degrees, this allows two straight lines of different length to connect the same points in space; in extreme degrees, theoretically, it could allow ti***ines to curve around in a circle and reconnect with their own past.

General relativity describes the universe under a complex system of "field equations," and there exist solutions to these equations that permit what are called "closed time-like curves," and hence time travel into the past. The first and most famous of these was proposed by Kurt G�del, but all known current examples require the universe to have physical characteristics that it does not appear to have. Whether general relativity forbids closed time-like curves for all realistic conditions is unknown. Most physicists believe that it does, largely because assuming some principle against time travel prevents paradoxical situations from occurring.


Using wormholes
http://www.crystalinks.com/timetravel_wormhole.jpg


A proposed time-travel machine using a wormhole would (hypothetically) work something like this: A wormhole is created somehow. One end of the wormhole is accelerated to nearly the speed of light, perhaps with an advanced spaceship, and then brought back to the point of origin. Due to time dilation, the accelerated end of the wormhole has now experienced less subjective passage of time than the stationary end.

An object that goes into the stationary end would come out of the other end in the past relative to the time when it enters. One significant limitation of such a time machine is that it is only possible to go as far back in time as the initial creation of the machine; in essence, it is more of a path through time than it is a device that itself moves through time, and it would not allow the technology itself to be moved backwards in time.

This could provide an alternative explanation for Hawking's observation: a time machine will be built someday, but hasn't been built yet, so the tourists from the future can't reach this far back in time.

Creating a wormhole of a size useful for macroscopic spacecraft, keeping it stable, and moving one end of it around would require significant energy, many orders of magnitude more than the Sun can produce in its lifetime. Construction of a wormhole would also require the existence of a substance known as "exotic matter," or "negative matter", which, while not known to be impossible, is also not known to exist in forms useful for wormhole construction (but see for example the Casimir effect).

Therefore it is unlikely such a device will ever be constructed, even with highly advanced technology. On the other hand, microscopic wormholes could still be useful for sending information back in time.Matt Visser argued in 1993 that the two mouths of a wormhole with such an induced clock difference could not be brought together without inducing quantum field and gravitational effects that would either make the wormhole collapse or the two mouths repel each other. Because of this, the two mouths could not be brought close enough for causality violation to take place.

However, in a 1997 paper, Visser hypothesized that a complex "Roman ring" (named after Tom Roman) configuration of an N number of wormholes arranged in a symmetric polygon could still act as a time machine, although he concludes that this is more likely than not a flaw in classical quantum gravity theory rather than proof that causality violation is possible.

[A Deo et Rege]

Using massive spinning cylinders

Another approach, developed by Frank Tipler, involves a spinning cylinder. If a cylinder is long, and dense, and spins fast enough about its long axis, then a spaceship flying around the cylinder on a spiral path could travel back in time (or forward, depending on the direction of its spiral). However, the density and speed required is so great that ordinary matter is not strong enough to construct it. A similar device might be built from a cosmic string, but none are known to exist, and it doesn't seem to be possible to create a new cosmic string.

Physicist Robert Forward noted that a na�ve application of general relativity to quantum mechanics suggests another way to build a time machine. A heavy atomic nucleus in a strong magnetic field would elongate into a cylinder, whose density and "spin" are enough to build a time machine. Gamma rays projected at it might allow information (not matter) to be sent back in time. However, he pointed out that until we have a single theory combining relativity and quantum mechanics, we will have no idea whether such speculations are nonsense.


Using Quantum Entanglement
http://www.crystalinks.com/quantumentanglement.jpg


Quantum mechanical phenomena such as quantum teleportation, the EPR paradox, or quantum entanglement might appear to create a mechanism that allows for faster-than-light (FTL) communication or time travel, and in fact some interpretations of quantum mechanics such as the Bohm interpretation presumes that some information is being exchanged between particles instantaneously in order to maintain correlations between particles. This effect was referred to as "spooky action at a distance" by Einstein.

Nevertheless, the rules of quantum mechanics curiously appear to prevent an outsider from using these methods to actually transmit useful information, and therefore do not appear to allow for time travel or FTL communication. This misunderstanding seems to be widespread in popular press coverage of quantum teleportation experiments. The assumption that time travel or superluminal communications is impossible allows one to derive interesting results such as the no cloning theorem, and how the rules of quantum mechanics work to preserve causality is an active area of research.

The possibility of paradoxes

The Novikov self-consistency principle and recent calculations by Kip S. Thorne indicate that simple masses passing through time travel wormholes could never engender paradoxes - there are no initial conditions that lead to paradox once time travel is introduced. If his results can be generalized they would suggest, curiously, that none of the supposed paradoxes formulated in time travel stories can actually be formulated at a precise physical level: that is, that any situation you can set up in a time travel story turns out to permit many consistent solutions. The circumstances might, however, turn out to be almost unbelievably strange.

Parallel universes might provide a way out of paradoxes. Everett's many-worlds interpretation of quantum mechanics suggests that all possible quantum events can occur in mutually exclusive histories. These alternate, or parallel histories would form a branching tree symbolizing all possible outcomes of any interaction.

Since all possibilities exist, any paradoxes can be explained by having the paradoxical events happening in a different universe. This concept is most often used in science-fiction. However, in actuality, physicists believe that such interaction or interference between these histories is not possible.

Time travel and the anthropic principle

It has been suggested by physicists such as Max Tegmark that the absence of time travel and the existence of causality may be due to the anthropic principle. The argument is that a universe which allows for time travel and closed time-like loops is one in which intelligence could not evolve because it would be impossible for a being to sort events into a past and future or to make predictions or comprehend the world around them.

Time Travel Equation

At speeds close to the speed of light, time is lengthened and distances
are shortened by a factor of the square root of (1 - v^2/c^2)
where v is the speed, and c is the speed of light.

it's not possible... I didn't read everyone else's thread, but It's not possible... you just can't...

IF you went back in time, it'd be pointless cuz you'd just be right back in your "old" body, and you would forget what you were doing cuz you went back in time... then you'de just do the same exact thing...

You apparently have never had any dealings with the field of physics or anything scientific because if you had you would know that nothing is impossible just improbable, meaning it can happen it is just very unlikely that it will. IF you had read my previous 4 or 5 post you would have a better understanding of why you are wrong. Unless you can produce some proof as to why time travel is impossible, and when I say proof I mean solid non-objectionable poof, then your statement has no verifiable scientific rectitude.

[superflysuperwhite]

the speed of light was broken once or is said to have been broken in the big bang and that is why the tempirature of the univers is pretty consistant

[itismesaj]

But why would that matter? There was nothing to compare the matter coming from the explosion to, so the speed of light would be independent of the speed of the matter exploding. Does that make sense?

[TotalAnarchyUK]

Time travel to the past is extremley improbable. IF we could travel back in time then we would be feeling the effects of this.

[itismesaj]

Thanks for repeating what I said a couple pages back ;).

[A Deo et Rege]

Time travel to the past is extremley improbable. IF we could travel back in time then we would be feeling the effects of this.

IF this is true please explain your reasoning on the matter. Why would we be feeling any effects from past oriented time travel, and has anyone read my previous post, if so what do you think?

[SuperSkunk]

The speed of light isn't as fast as you think. I figured it out. The fasters something goes the faster through time it goes or something which sort of increases the speed or something. So like it makes it go faster or something.

I haven't really thought of this at all I just wrote as I thought.

Iam just saying, if their is a basis that there is a past present and future, then surely the people in the future would have traveled back to a time to this time or the past. Or maybe they have traveled back in time, but to our future and their past. Hmmm, this is more confusing then I thought.

[Basarab]

I don't think you can literally go back in time, but I think you can reconstruct it with data collected outside out feild of vision. Everything we see right now in the sky happened a long long time ago. If you see a black hole a million light years away, chances are it has evaporated and all that is left is its ring/galaxy from when it was sucking everything up while it was a quasar. God damn, Ive posted like 6 comments like this, just tell me to stop = \
