	M Theory Visionists - Van Stokum Cylinder (Sol's Time Travelling Guide of Mandalics Origins)
		The materials may be practically "exotic" and the energy requirements enormous, but according to Dr. Frank Tipler of Tulane University in 1974, the construction of a time machine is theoretically feasible.
		Tipler assumed that the energy density was never negative and showed that closed timelike curves could never arise in a local region without also creating a singularity.
		This was reassuring, as we could hope that both the singularity and the closed timelike curves were hidden behind an event horizon (although this was not part of the proof).

		Tipler’s physics and not on the need to sell a good Sci-fi story.) Tipler’s original paper mentioned above is difficult to obtain but nevertheless there is plenty of mention of the “Tipler Cylinder” as a time machine and/or time warp transport all over the Internet.
		Of course the "Tipler Cylinder" is a mental exercise for understanding gravitational distortions of spacetime, while traveling close to the speed of light may one day become a remote engineering possibility.
		Tipler's a great scientist and writer, but he said in 'The Physics of Immortality' that when we die we'll wake up in some computer programme in the far flung future.

	Into the Future
		Tipler's work on the relationship of general relativity and rotating cylinders showed light speed is unnecessary to time travel.
		Tipler had designed a machine constructed on the principle of a rotating cylinder.
		Using the super-computers we had access to at APL, I helped him design a model to simulate Tipler's rotating cylinder of super dense material that could revolve several billion times a minute which would be necessary generate enough centrifugal force to offset the extreme gravitational attraction.

	Time Travel
		Tipler predicts that a ship following a carefully plotted spiral course around the cylinder would immediatly find itself on a "closed, timelike curve." It would emerge thousands, even billions, of years from its starting points and possibly several galaixes away.
		For the mathematics to work properly, Tipler's cylinder has to be infinetely long.
		As a variation on the rotating cylinder, some scientists have suggested using "cosmic strings" to construct a time machine.

		Tipler's work, published in respectable journals such as the Physical Review and Annals of Physics, is necessarily highly mathematical and not always easy for the uninitiated to follow.
		Tipler has proved that a traveller from a weak field region - the Earth, say - could go to a strong field region near such a rotating object, move in the direction of negative time, and then return home to the weak field region without ever violating any known physical law.
		Tipler, cautiously, says only that 'we are a very long way from completely resolving the causality violation question.' But that, coming from a respected mathematical physicist with a thorough knowledge of Einstein's theories, speaks volumes.

		Another approach — attributed to Frank Tipler, but invented independently by Willem Jacob van Stockum [3] in 1936 and Kornel Lanczos [4] in 1924 — 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).
		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.

		Prof FRANK TIPLER: We like to think that what we’re going to do tomorrow is undetermined except by what we decide to do but in the Newtonian view our detailed action tomorrow was determined in the beginning of time.
		Prof FRANK TIPLER: Now it occurred to me another rotating body which would not have the surface of a fl hole is a long extended cylinder.
		I was able to prove that inevitably if you were to spin up a cylinder sufficiently rapidly it would necessarily have a region around it that would permit time travel, permit you to go around the cylinder and return to your starting point far away from the cylinder before you left, true time travel.

	Frank J. Tipler - Wikipedia, the free encyclopedia
		Frank J. Tipler (born in 1947 in Andalusia, Alabama) is a professor of mathematical physics at Tulane University, New Orleans, physicist, theologian, cornucopian philosopher and intelligent design advocate.
		Other scientists, such as Oxford physicist David Deutsch, find Tipler's arguments compelling.
		Tipler's writings on scientific peer review have been cited by William A. Dembski as forming the basis of the process for review in the intelligent design journal Progress in Complexity, Information and Design of the International Society for Complexity, Information and Design, where both Tipler and Dembski serve as fellows.

		There are a number of uses for such a time communicator, one of which is predicting the future, another is to serve as an FTL communicator that erases time delays imposed by the speed of light in communications.
		The theory is that a spinning ultradense cylinder is supposed to drag space along with itself, their are certain zones that drag space around itself at FTL speeds while locally with relation to the cylinder remain STL.
		This process builds in no elapsed time until the point is reached where you have just enough photons to destroy the wormhole at the first instant that the two ends are close enough where casuality violations become possible.

		In fact, the burden of proof is now far and away upon the doubters of time and dimensional travel to make their case that such are impossible.
		To simplify once more, psychics were again utilized to visualize and stabilize a target destination in a different time/space dimension which the vortex would then be focused upon.
		The Tipler cylinder, a concept formulated by the aforementioned physicist Frank Tipler, is presently one of the most widely accepted theoretical models in quantum physics of how to create an artificial, controllable "fl hole", thereby achieving time-space and dimensional shifting and even the ability to effect alterations and manipulations of our time-space continuum.

		take a long cylinder of neutronium, spin it up to the something approaching the speed of light, and the math says that you can plot a course around it that will take you backwards in time.
		Namely that the cylinder needs to be essentially ten neutron stars strung in a line, and three alone will quite promptly collapse into a fl hole.
		We've not seen them anywhere in the universe though, and Hollywood scriptwriters have explained as well as anyone why this can be a bad thing to allow.

	Dean's World - "Artificial Gravity a Reality?"
		I think we'll find that time travel is not possible, and relativity is simply failing to properly describe the Tipler phenomenon, much as Newtonian physics fails to describe the movement of objects near lightspeeed.
		In fact, this experiment is a little bit similar to a Tipler cylinder (well, it spins, anyway), so who knows, it might be on to something in that regard.
		Though as SDB points out, this needs to be replicated, and as Sean points out it may never have a practical application (fusion power is still "50 years away," just like it was 50 years ago).

		In 1974, Frank Tipler shocked the scientific community when he published a paper that appeared to be plans for building a time machine!
		Using a massive rotating cylinder in space Tipler showed how not only forward, but reverse time travel, were both possible without violating the laws of mathematics and physics.
		This "rotating cylinder" model continues to be one of the best examples that shows how time travel is clearly possible within the laws of mathematics and physics!

		The interesting thing about this particular time machine is that it doesn't require any particularly unusual physics and appears to get around some fairly abstruse objections that physicists have raised to time machines in the past.
		Somewhat related to fl holes and Tipler cylinders are "wormholes", a theoretical "subway" between two distant points in physical space.
		In the case of fl holes or Tipler cylinders or whatever, you can't go back any further than when the time machine was "spun up".

	Book Review: Nahin, 'Time Travel'
		The first option is a rotating fl hole, through which a theoretical traveler could pass to another universe or time.
		There’s Tipler’s rotating cylinder, which could cause a distortion of space-time, as another option (although it would only allow the traveler to go into the future, and there is a problem with actually building a near infinitely-long cylinder that rotates at near light-speed, no one seems to disagree that it would work).
		Nahin thinks wormholes, his third option, are actually the most likely candidates for working time machines, but he lists one last candidate, cosmic strings (which have not been much used in fiction so far, apparently: go for it!).

		But the difference between this nutball and other nutballs is that this one had done some serious research beforehand.
		A series of computers take a "gravity lock" on the point of exit, and compensate for galactic shift and Earth's orbit to allow the traveller to re-emerge with normal space at the point of departure, and different time.
		Titor has since popularized this theory, but he was certainly one of the first to put both Kerr and Tipler theories together in such a way.

		A cosmic string is a linear singularity that manifests its vast mass by creating a reduction of the value of pi when measured around its circumference.
		A tipler cylinder is a cylinder with a very large mass (about 100 times that of the Sun would be a bare minimum) artificially constructed and set spinning so that the outer edge is near lightspeed.
		Both of these methods are similar, and create a closed timelike curve, which would allow one to move about in spacetime in higher dimensions
