A new concept for a time machine could possibly enable distant future generations to travel into the past, research now suggests. Unlike past ideas for time machines, this new concept does not require exotic, theoretical forms of matter. Still, this new idea requires technology far more advanced than anything existing today, and major questions remain as to whether any time machine would ever prove stable enough to enable actual travel back in time. Time machine researchers often investigate gravity, which essentially arises when matter bends space and time. Time travel research is based on bending space-time so far that time lines actually turn back on themselves to form a loop, technically known as a "closed time-like curve." "We know that bending does happen all the time, but we want the bending to be strong enough and to take a special form where the lines of time make closed loops," said theoretical physicist Amos Ori at the Technion-Israel Institute of Technology in Haifa. "We are trying to find out if it is possible to manipulate space-time to develop in such a way."

Many scientists are skeptical as to whether or not time travel is possible. For instance, time machines often are thought to need an exotic form of matter with so-called "negative energy density." Such exotic matter has bizarre properties, including moving in the opposite direction of normal matter when pushed. Such matter could theoretically exist, but if it did, it might be present only in quantities too small for the construction of a time machine. Ori's latest research suggests time machines are possible without exotic matter, eliminating a barrier to time travel. His work begins with a donut-shaped hole enveloped within a sphere of normal matter. "We're talking about these closed loops of time, and the simplest kind of closed loops are circles, which is why we have this ring-shaped hole," Ori explained. Inside this donut-shaped vacuum, space-time could get bent upon itself using focused gravitational fields to form a closed time-like curve. To go back in time, a traveler would race around inside the donut, going further back into the past with each lap.

I think to better understand time travel, we should understand what time is. Time is produced by the gravitational annihilation of space and the extraction of a metrically equivalent temporal residue. The intrinsic motion of time is the entropy drive of bound energy and creates the historic conservation domain of information and matter's "causal matrix" (historic spacetime). (Time is also ultimately gauged by c, since "velocity T" is defined as the duration (measured by a clock) required for light to travel a given distance (measured by a meter stick). "G" is therefore related to "c" through their common factor time, and as entropy is related to energy.) Time is a local and flexible dimensional gauge produced by the gravitational annihilation of space.

The graviton is the presumed field vector of gravitation, the local symmetry current exchanged between all massive particles (via its effect upon the spacetime metric). The graviton is actually a form of time or spacetime. A graviton is a quantum unit of time or temporal entropy. All massive objects have a "location" charge, whose active principle is time, and as the time charge exits space (at right angles to all three spatial dimensions, marching off into history), time pulls the spatial dimensions along behind it, causing them to annihilate each other at the point-like entrance to the time line, leaving a temporal residue which is the metric equivalent of the collapsed space. This new temporal residue likewise moves off down the time line into history, pulling more space behind it, repeating the endless entropic cycle. The collapsing space is the gravitational field in which all things "fall" with an equivalent acceleration (all things become co-movers with the spatial flow). A gravitational field is the spatial consequence of the intrinsic motion of time.

...If the last sentence is correct, what happens when a gravitational field is shielded? Gravitational Time Dilation. Gravitational time dilation was first described by Albert Einstein in 1907 as a consequence of special relativity in accelerated frames of reference. In general relativity, it is considered to be difference in the passage of proper time at different positions as described by a metric tensor of spacetime. The existence of gravitational time dilation was first confirmed directly by the Pound-Rebka experiment. http://en.wikipedia.org/wiki/Gravitational_time_dilation

Quantum mechanics and gravity shielding...But George Muellner of Boeing has been quoted as saying that the science of the antigravity device appeared to be valid and possible. Why did he say that?
http://news.bbc.co.uk/1/hi/sci/tech/2159487.stm

The project is being run by the top-secret Phantom Works in Seattle, the part of the company which handles Boeing's most sensitive programmes.
http://news.bbc.co.uk/2/hi/science/nature/2157975.stm

...a Russian materials scientist claimed to produce a shielding effect from a spinning, high temperature superconductor, above which the terrestrial gravity field was attenuated by several percent. ...But, such a gravity-emulating, Maxwell gauge field cannot be massless, otherwise it would have long since been detected. If it exists at all, it must be in the unexplored supersymmetry realm between 1 and 100 TeV. The warp field of a length-time 'photon' would, accordingly, take the form of a micro-warp in the 10^-17 to 10^-19 cm. range. In this view, the lobe-like complexity of electron orbits would stem from oscillations of the length and time variables, confined within a 10^-17 cm. effective warp 'bubble' that should act like a cavity resonator. Thus, throughout its complex gyrations, an orbiting electron would locally be shielded from inertial forces, as the amplitude and orientation of the micro-warp synchronizes with the dynamically changing angular acceleration vector.

who was it that said time travel was not possible...ive been trying to search it but i cant find the guys name. not that i dont believe it might be possible i was just going to use him as a refrence to his points at why it might NOT be possible. of course you do bring a big point on how it COULD be possible. if we did find a way to travel back into time it would be a very big danger and may cause a time peridox and screw things up majorly. like that one movie when they went back into time and they killed a bug and it changed every thing. things like that could happen and it is one little thing. if we do find a way to go back into time. i think humans have gone to far into trying to explain things it will be the end of humans if they do.
(btw sence i like cars the car in that picture is the 1981 DMC Delorean M-12 used in Back To The Futur)

although i see i am a bit under educated about this topic...so i wont post no more on this topic dont wanna make a fool of myself with my lack of knowledge

I believe that time travel is possible but only as an outside viewer. There would be no way to interact with anyone or anything in the time view you are witnessing. I do believe that in the distant future science will discover how to do this.

"when this baby hits 88mph youre going to see some serious $h!t"

time is a man made essence of the universe. If it weren't ever for a clock there would never be time. Just day and night.

The concept of time travel is flawed.

No point on earth is ever in the same spot, i.e. the earth moves around the sun, and the sun moves through the galaxy.

I find it highly unlikely that even if a discovery was made that the exact spot the solar system was in could be figured out when you get down to the speeds the sun moves at as well as gravitational effects from other stars.

I hope that makes some sense - it's a flaw in time travel (like BTTF among others) that has always bothered me, the fading from the future/appear in the past in the same spot. Fundamentaly impossible.

true but it makes for a good movie.

This has never occured to me before. Thank you for making me think.

Wuh-huh? I'm reading lots of big words but they don't make any sense to me.
"Time is produced by the gravitational annihilation of space and the extraction of a metrically equivalent temporal residue." What?!?
"The intrinsic motion of time is the entropy drive of bound energy and creates the historic conservation domain of information and matter's "causal matrix" (historic spacetime)."
I give up. You're stringing lots of big words together in ways that convey no meaning at all to me. Could you simplify what you are saying so that a simple mechanical engineer can understand? I'm not trying to make trouble, I'm just trying to understand what you're saying. If your understanding of space-time makes time travel possible, I very much want to understand it. Thanks.

Nonsense. A human observer is not needed for the sun to slowly rise in the east, climb to the top of the sky and then slowly set in the west. No human is needed to observe an apple rotting into the ground over days. Before humans even came to be, Earth's seasons went summer/winter/summer/winter...

If a tree falls in a forest and there is no human to hear it...of COURSE it makes a sound! Humans are dust motes on a dust mote in a distant corner of a dust mote. We do not matter!

all my studies have shown that actually traveling to the past is so implausible that it's just one step from impossible. Building a time machine, like what you see in that stupid Back to the future movie is even closer to impossible than traveling to the past.

Now I do fully believe that one day I will figure out how to travel to the future, and maybe if I travel far enough forward maybe I'll end up in the past.

Time travel is possible, past and future, however, going back to the past would displace the traveler (he would have no way of returning to his "origin time" and thus the people who seen him off would never see him again.


Traveling to the future is possible however would reveal a somewhat possible future, but at least he would be able to return to his origin (however his return to the Origin resets the futures possibilities.
You could take something from the future and return back to your original time with it, that would be neat.

At least thats my theory on it.

No it isn't .

Do you have a computer program that randomly selects words from a physics spellchecker dictionary, and then throws a few adjectives and linking words etc inbetween ?


I don't think they're SUPPOSED to make sense Blizno

Meow Purr.

I'll try and simplify this a bit.

"Time is a local and flexible dimensional gauge produced by the gravitational annihilation of space."

"A gravitational field is the spatial consequence of the intrinsic motion of time."

"The existence of gravitational time dilation was first confirmed directly by the Pound-Rebka experiment."

Read my thread on Superlight from the UFO forums.

My ans:


The links I have provided attempt to explain this: If time is created by a gravitational distortion of the space time fabric by the gravity field of mass, what happens when mass is shielded from the affects of gravity?...what happens to time, and what can shield mass from the affects of gravity?

...is this what is really going on with anti-gravity research? I propose that the Cosmological Constant is a field of energy that in whose presence causes mass to react to each other as an attractive force known as gravity, that mass in the absence of this field, has no gravity at all, ...that time is caused by the gravitational distortion of the gravity created from the field of Superlight aka the Aether, aka the Zero-Point Field aka the Cosmological Constant as it interacts with mass, ...that if a material can be found that does not react as normal mass does in this field, that can shield the effects of this field known as superlight from ordinary mass, then we can affect gravity and time as well.

Antigravity research is related to crystals, and the anomoly is happening only in crystals...a material known as the superconductor.

The Podkletnov Gravitational-Shield,

In 1992, while working at Tampere University in Finland, Russian scientist Eugene Podkletnov was experimenting with rotating superconductors and noticed that a column of pipe-smoke from a nearby researcher was drifting into a vertical column above the spinning superconductive disk.

"He devised an experiment in which a disc of superconducting material was magnetically levitated and rotated at high speed, up to several thousand rpm, in the presence of an external magnetic field. In the course of the tests, Podkletnov noted that objects above the rotating disk showed a variable but measurable loss of weight, from less than .5 percent to about 2 percent. He had no explanation," said Ron Kockzor, of NASA's Marshall Space Flight Center...as a consequence of what Podkletnov found, Nasa and Boeing are researching anti-gravity.

I believe that what is known as anti-gravity research that is going on right now has a lot more ramifications then lightening the payload of future spaceflights...that this theory of time and time travel is being tested. If we can deduce by science that time is created by gravity, then what happens with anti-gravity?...read this report from CNN: "Boeing, the world's largest aircraft manufacturer says it is working on anti-gravity propulsion, which could revolutionize conventional aviation." ...and a whole lot more...the link: http://www.cnn.com/2003/TECH/09/05/wow.tech.black.world/
Therefore, your time machine will come about from the use of certain superconductors that shield mass from the ZPF.
