Danger Will Robinson! Some of the following information is serious, and some is nonsense. Some of the things that might at first seem to be nonsense, are not. And some things referenced below, which come from serious credentialed scientists, are in fact nonsense. Whatever the case, it's been included. Good luck sorting it out. Understanding gravity is a matter of time.

Many references to this effect are contained in this resource list. But for now, let's forget about the experimental evidence and theoretical ideas which are presented here, and begin with first principles. What if our knowledge of physics had evolved differently? What if no one had ever given a thought to any theory of gravitation, before we discovered the principles and theories of electromagnetics and the two nuclear forces. We might have developed some fairly good theories which unify the "three" forces. We would know that clumps of matter are held together primarily by electromagnetic forces. And we would find experimentally that if we separate some of these clumps of matter, a small force continues to exist which trys to bring them back together. Would it seem rational to speculate that this force is something entirely new and completely different from electromagnetics? Would it not be a great foolishness to invent something new and call it gravity and claim that it has no relationship with the known forces, and then write elaborate mathematical theories which describe it solely as geometry? Or, would it be more rational to see it as what it probably is -- a manifestation of the electromagnetic forces which we already know to hold matter together? Could it be that electric charge is a fundamental thing, and inertial mass is merely a shadow of something primal, and what we know as a gravitational field is merely the net result of other primary fields? Geometrize it if you find it useful to do so, but please recognize that defining gravity as geometry lends no information to the understanding of its cause. Of all the forces we know, there is none stronger than a paradigm. -- Robert Stirniman ------------------------------------------------------------------------ GENERAL RELATIVITY & QUANTUM COSMOLOGY, ABSTRACT GR-QC/9512027 From: kldalton@cs.clemson.edu Date: Tue, 12 Dec 1995 11:30:30 -0500 Author(s): Kenneth Dalton Journal-ref: Hadronic J. 17 (1994) 483-501 Hypothesis: The electromagnetic field is the source of gravitation. This treatment of gravitation is consistent with the quantum theory of matter, which holds that electric charge (or `generalized charge') is the most fundamental attribute of matter. Experimental predictions of the theory include: (1) any massive body generates a time-dependent gravitational field; (2) there is a linear correlation between the gravitational red-shift of a stellar source and the energy of cosmic rays emitted by that source, given by $ {\Delta \nu}/{\nu_0} = energy (eV)/10^{27} $; (3) the maximum energy of cosmic rays is $ 10^{27} $ eV; (4) this limit is associated with an infinitely red-shifted stellar object, an ``electrostatic black-hole,'' at the potential $ c^2/G^{1/2} = 10^{27} $ volts. Finally, the theory predicts that the gravitational potential near any charged elementary particle is many orders of magnitude greater than the Newtonian value. HIGH ENERGY PHYSICS - THEORY, ABSTRACT HEP-TH/9601066 From: Kenichi Horie Date: Sat, 13 Jan 1996 14:41:29 +0900 Geometric Interpretation of Electromagnetism in a Gravitational Theory with Torsion and Spinorial Matter Author(s): Kenichi Horie (KEK Japan) Comments: Ph.D. thesis, 98 pages, LaTeX file, ca 276kB Possible geometric frameworks for a unified theory of gravity and electromagnetism are investigated: General relativity is enlarged by allowing for an arbitrary complex linear connection and by constructing an extended spinor derivative based on the complex connection. Thereby the spacetime torsion not only is coupled to the spin of fermions and causes a four-fermion contact interaction, but the non-metric vector-part of torsion is also related to the electromagnetic potential. However, this long-standing relation is shown to be valid only in a special U(1) gauge, and it is a formal consequence of the underlying extended geometry. -------------------------------------------------------------------------- Salem, Kenneth G.

Hooper, BA, MA, PhD in Physics was affiliated with the University of California at Berkley, and was Professor Emeritus, when he died in 1971. His works are documented and he gained two U.S. patents for his "ALL-ELECTRIC MOTIONAL FIELD GENERATOR". He claimed use of the "Motional Electric Field" to produce gravity and anti-gravity for use in SPACECRAFT and AIRCRAFT. Indeed, in U.S. patent #3,610,971 you can see a Flying Saucer diagram is used as an example in Figure 7. -- James Hartman, CaluNET Future Science Administrator US Patent #3,610,971.

Gibson, "THE ALL-ELECTRIC FIELD GENERATOR AND ITS POTENTIAL", Electrodynamic Gravity, Inc., 1983 "Electric Propulsion Study", Dr. Dennis Cravens, SAIC Corp, prepared for USAF Astronautics Lab at Edwards AFB, August 1990 -- Section 3.7 Non-Inductive Coils Several authors have suggested that v x B term in the Lorentz expression should be called into question. Several unverified experimental results have ever been made. An experiment is suggested to test one or several of these theoretical views. This is an area where the experimental procedure is workable and the outcome could have direct results in the area of inertia forces. During the late 60's William J. Hooper put forth an interesting theory involving the v x B terms dynamic electrical circuits. There was and is uncertainty as to the exact physical understanding of the Biot-Savart-Lorentz law and Ampere's law involving the set of reaction forces. Peter Graneau has studied these expressions. Hoopers view was that there are three different types of electric fields due to the distribution of electric field, and two due to induction. At the heart of the issue is the connection of the magnetic field and its source in the charged particles. EM theory is presently consistent with the idea that spinning magnetic dipoles create effects indistinguishable from charged particles. There has been no critical experiment which can disprove whether a magnetic flux rotates with its source. If it does co-move with its source then it is logical to assume that a motional electric field in a fixed reference frame of the current induces a magnetic field. This concept is likewise consistent with a field-free interpretation such as Ampere's original laws. (with 4 pages more about Hooper's theories) FREE FALL OF ELEMENTARY PARTICLES: ON MOVING BODIES AND THEIR ELECTROMAGNETIC FORCES, by Nils Rognerud 1994 (nils@ccnet.com) (available at the elektromagnum web site) This paper is a review of the problem of the observable action of gravitational forces on charged particles. The author discusses the induced electric fields and the sometimes overlooked unique physical properties. He analyzes several experiments, showing the reality of the induced electric fields. The current interpretation, based on the idea of only one electric field, with certain characteristics, is compared with alternative approaches. The Hooper Coil: The author has tested a setup by pulsing strong currents, opposite and equal, through multiple parallel conductors. The configuration of the conductors in this type of experiment will cancel the B-fields, while still producing an Em field, in accordance with Eq. 4.2. This is similar to an experiment by Hooper (W. J. Hooper), who successfully predicted and measured the motional electric field - all in zero resultant B-field. Interestingly, all of the above experiments can influence an electron with a zero B-field, in the region of the electron. This has some profound implications - one of which is that the motional electric force field is immune to electrostatic or magnetic shielding. Experimentally, it can be confirmed that the motional electric field is immune to shielding and follows the boundary conditions of the magnetic (not electric) field. The only way to shield a motional electric field is to use a magnetic shield around the source of the magnetic flux - containing it at the source. These effects are not startling if one remembers that the motional electric field is a magnetic effect and that a magnetic field has a different boundary condition than the electric field. ---------------------------------------------------------------------- US Patent #3626605 -- "Method and Apparatus for Generating a Secondary Gravitational Force Field" Awarded to Henry Wm Wallace of Ardmore PA Dec 14, 1971 US Patent #3626606 -- "Method and Apparatus for Generating a Dynamic Force Field" Awarded to Henry Wm Wallace of Ardmore PA Dec 14, 1971 US Patent #3823570 -- "Heat Pump" (based on technology similar to the above two inventions) Awarded to Henry Wm Wallace of Freeport NY July 16, 1973 ----------------------------------------------------------------------- Gravity is a PUSH! United States Patent Number 5,377,936 NET KINETIC ENERGY DIFFERENTIAL GUIDANCE AND PROPULSION SYSTEM FOR SATELLITES AND SPACE VEHICLES ------------------------------------------------------------------------ In the early 1960s, Erwin Saxl conducted a series of experiments which seemed to illustrate a non-zero coupling between EM and gravitational fields. He claimed to see a change in the period of a torque pendulum when its electric potential was raised. US Patent # 3357253 -- "Device and Method for Measuring Gravitational and Other Forces", awarded to E.J. Saxl, December 1967 "An Electrically Charged Torque Pendulum", by E.J. Saxl, Nature 203, Page 136, July 11 1963. -------------------------------------------------------------------------- US patent number #5,076,971. Barker places radioactive elements inside the sphere of a Van de Graaff generator, runs it at a negative potential for several minutes/hours/days -- and finds that the rate of radioactive decay is extremely enhanced -- with some relationship to the magnitude of the negative potential. The principal investigator undertook a series of experiments to test the "Barker effect" and the "Keller Catalytic Process" in changing the rate of radioactive decay of heavy elements (elements heavier than lead, such as radium, thorium, or uranium, all of which are radioactive). Barker claims that subjecting radioactive materials to high electrostatic potentials (50,000 volts to 500,000 volts) can increase or decrease the rate of radioactive decay, with short exposures of the high voltage capable of inducing erratic decay rates which slowly return to normal over a period of weeks. Keller claims that subjecting radioactive materials to the high heat and fusing reaction of a chemical process (Keller Catalytic Process) can eliminate the radioactivity completely. -- Michael Mandeville http://www.aa.net/~mwm/dexmrad1.html ----------------------------------------------------------------------- Carr, Otis (1959). "Amusement Device," (i.e. A Flying Saucer), US Patent No. 2,912,244. Otis Carr's work involved counter-rotating charged discs that supposedly produced thrust when they reached a certain speed in relation the the earth's rotational speed and became activated by free energy from space. Maybe he did have something." -- James E. Cox Carr's work is similar in some respects to Hooper's inventions. In both cases, an anti-gravitational effect is reported to result from equal and opposite electric currents. Furthermore, one of Hooper's embodiments, the pancake coil, has an uncanny resemblance to the gravitational shielding experiments which were recently conducted in Tampere Finland (1992 and 1995). Except that in the Tampere experiments, the equal and opposite current is generated in a superconductor disk by way of the Meissner effect. Will we soon begin to recognize value of the discoveries that Carr made nearly 40 years ago, and Hooper made over 25 years ago? -- Robert Stirniman ------------------------------------------------------------------------- EXPERIMENTAL RESULTS OF HOOPER'S GRAVITY-ELECTROMAGNETIC COUPLING CONCEPT National Aeronautics and Space Administration. Lewis Research Center, Cleveland, OH. MILLIS, MARC G. WILLIAMSON, GARY SCOTT JUN. 1995 12 PAGES Presented at the 31st Joint Propulsion Conference and Exhibit, San Diego CA, 10-12 Jul. 1995; sponsored by AIAA, ASME, SAE, and ASEE NASA-TM-106963 E-9719 NAS 1.15:106963 AIAA PAPER 95-2601 Avail: CASI HC A03/MF A01 Experiments were conducted to test assertions from Patent 3,610,971, by W.J. Hooper that self-canceling electromagnetic coils can reduce the weight of objects placed underneath. No weight changes were observed within the detectability of the instrumentation. More careful examination of the patent and other reports from Hooper led to the conclusion that Hooper may have misinterpreted thermal effects as his 'Motional Field' effects. There is a possibility that the claimed effects are below the detection thresholds of the instrumentation used for these tests. CASI Accession Number: N95-28893 I have two problems with the methodology used by the NASA scientists in the above experiment. First -- The amount of ampere-turns used in the NASA experiment was substantially lower than the amount used by Hooper. Hooper found that his effect increased in proportion the square of the current. If you were motivated to verify that the Hooper effect exists, would you not try to conduct the experiment with MORE current, rather than less? Second -- NASA conducted it's tests by energizing the coils and making measurements in an immediate on-off mode, rather than letting things run for a while as Hooper did. NASA's reason for doing this was to avoid errors due to thermal effects. This makes sense. But what does not make sense is that if you are trying to verify an original experiment and you make changes, you have an obligation to also conduct the experiment in it's original mode. To do otherwise is bad science. But what could be wrong with testing things in an immediate on-off mode? Well, it can be seen in other experiments that a gravitational effect sometimes results from macroscopic spin alignment of the quantum angular momentum of a large number of microscopic particles. It has been demonstrated in other experiments that it takes time for these particles to come into alignment. For example in the inventions of Henry Wallace it sometimes took minutes for the "kinemassic" gravito- magnetic field to fully manifest itself. The reason that it takes time for particles to come into alignment, could be much the same reason that it takes time to permanently magnetize a magnet. Wallace found that the "kinemassic" effect occurs with elemental materials which have a component of unpaired spin in the atomic nucleus. This includes all common isotopes of copper, which of course is the material used in Hooper's coils. Incidently, NASA essentially has an economic monopoly in the lucrative market for microgravity materials research. -- Robert Stirniman ------------------------------------------------------------------------ The Hooper effect can be readily demonstrated in the "Two Moving Magnets Experiment". In this experiment, magnetic flux is provided by equal strength opposite pole magnets, moving uniformly in opposite directions. The induced motional electric field that is generated in a conductor, is found to be twice that which would result from a single magnet, while remarkably, the sum of the magnetic B field is zero. This experiment is easy to setup and verify in any electronics laboratory with a pair of magnets, a wire, and a voltmeter. In fact, you may wrap the conductor, in electrostatic or magnetic shielding, and find the same result. -- Nils Rognerud Oleg Jefimenko, "Causality, Electromagnetic Induction, and Gravitation", Electret Scientific, Star City, (1992) Oleg Jefimenko, "Force Exerted on a Stationary Charge by a Moving Electric Current or a Moving Magnet", American Journal of Physics, Vol 61, pages 218-222 (1993) ------------------------------------------------------------------- Apparently, there are some VERY interesting clues to the nature of the universe that are related to the phenomenon of SPIN. It might get very interesting if someone were to make a project of assembling in one place all the information that has been observed, alleged, suspected, or speculated about concerning unexpected effects related to spin, along with all the traditional Newtonian results, stir, add some seasoning, and see what comes out. For example, in quantum mechanics, if you want to measure the spin axis of an electron, you do an experiment in which you ASSUME an axis, make a measurement of the correlation (the dot product) of that axis with the actual axis of spin for that electron, and theory says you can determine at least how close your guess was. It was a major surprise for the first expermienters with this to find that the guess was always right: whatever spin axis you assume turns out to be correct, exactly dead accurate. You must be a VERY good guesser. Out of this experimental result came the concept of "isospin". Which in itself is kind of weird in that objects with zero radius can still exhibit spinx. But I find the idea that the spin is wherever you guess it might be to be even weirder and to need a better model that predicts this result. -- John Sangster -------------------------------------------------------------------------- Paper: gr-qc/9311036 From: jaegukim@cc.kangwon.ac.kr Date: Tue, 30 Nov 93 13:47:52 +0900 Gravitational Field of a Moving Spinning Point Particle, by Jaegu Kim, 7 pages, The gravitational and electromagnetic fields of a moving charged spinning point particle are obtained in the Lorentz covariant form by transforming the Kerr--Newman solution in Boyer--Lindquist coordinates to the one in the coordinate system which resembles the isotropic coordinates and then covariantizing it. It is shown that the general relativistic proper time at the location of the particle is the same as the special relativistic one and the gravitational and electromagnetic self forces vanish. Jaegu Kim, "Gravitational Field of a Moving Point Particle", Journal of the Korean Physical Society, Vol 27 No 5, Oct 94, Pages 484-492 Jaegu Kim, "Gravitational Field of a Moving Spinning Point Particle", Journal of the Korean Physical Society, Vol 27 No 5, Oct 94, Pages 479-483 In the above papers, Dr. Kim derives solutions for the Einstein-Maxwell equations for: a charged massless point particle, a point particle having mass but no charge, a point particle having mass and charge, a massless point particle with charge and spin, and finally -- a point particle having charge, mass, and spin. He determines that there is a region of space around a charged spinning mass in which the gravitational force is negative. The ability to generate a negative gravity effect may come as no surprise to experimenters who have worked with Bose-Einstein condensates, superfluids, or superconductor material in which the angular momentum of quantum level particles can become aligned along a "macroscopic" spin axis. And it is probably also not a surprise to those who have looked at devices such as the inventions of Henry Wallace, in which a macroscopic body is mechanically spun at high speed in order to cause a "kinemassic" gravito-magnetic field due to spin alignment of the nucleus of elemental materials having an odd number of nucleons (un-paired spin). --------------------------------------------------------------------- Paper: GR-QC/9504023 Date: Mon, 17 Apr 1995 10:43:50 +0900 Title: Pure spin-connection formulation of gravity and classification of energy-momentum tensors Author: Mathias PILLIN Report-no: YITP/U-95-12 It is shown how the different irreducibility classes of the energy-momentum tensor allow for a pure spin-connection formulation. Ambiguities in this formulation especially concerning the need for constraints are clarified. ------------------------------------------------------------------------ From: R.Bursill@sheffield.ac.uk (R Bursill) Subject: Hi Tc SC and gravitational shielding Date: Fri, 6 Oct 1995 03:14:41 GMT Is anyone familiar with the experiments in Tampere Finland, by Podkletnov et al on weak gravitational shielding from a Meissner levitating, rotating disk of high-Tc superconducting material? The paper is: E. Podkletnov and R. Nieminen, Physica C 203 (1992) 441. E. Podkletnov and A. D. Levit have another paper now, a Tampere University of Technology report, January 1995 (Finland), the experiment having being repeated (I assume no one believed it the first time?). In the 1st experiment a 5 g sample of silicon dioxide was found to loose around 0.05 % of its weight when placed at a distance of 15 mm from the SC disk. The SC disk had diameter 145 mm and thickness 6 mm. Under rotation of the disk the effect increased up to 0.3 %. In the 2nd experiment samples of different composition and weight (10-50 g) were placed at distances of 25 mm to 1.5 m from the disk. The mass loss went as high as around 2 %. I found out about this through a theoretical preprint by Giovanni Modanese, a Von Humboldt Fellow from the Max Plank institute. The preprint no. is MPI-PhT/95-44, May 1995. A colleage got it from hep-th@babbage.sissa.it, paper 9505094. Modanese thinks that it is something to do with the bose condensate from the SC interacting with the gravitational field. He uses some non-perturbative quantum theory on the Regge lattice to attempt to understand the effect. Must be a little bit like explaining cold fusion with the standard tools - couldn't be done. We all know what happened to cold fusion but at the time a professor from my department said in a public lecture that the product of the believability and the potential importance if true was of order 1. - Robert Bursill ------------------------------------------------------------------- E.

Modanese (Max-Planck-Institut, Munich) Report-no: MPI-PhT/95-44 May 1995 Under special conditions (Meissner-effect levitation and rapid rotation) a disk of high-Tc superconducting material has recently been found to produce a weak shielding of the gravitational field. We show that this phenomenon has no explanation in the standard gravity theories, except possibly in the non-perturbative quantum theory on the Regge lattice. More data, and independent repetitions of the experiment are however necessary. ABSTRACT SUPR-CON/9601001 From: Modanese Giovanni Date: Wed, 17 Jan 1996 21:54:45 +0100 (MET) Updating the analysis of Tampere's weak gravitational shielding experiment Author: Giovanni Modanese Report-no: UTF-367/96 The most recent data about the weak gravitational shielding produced in Tampere by Podkletnov and coworkers through a levitating and rotating HTC superconducting disk show a very weak dependence of the shielding value ($\sim 1 \%$) on the height above the disk. We show that whilst this behaviour is incompatible with an intuitive vectorial picture of the shielding, it is consistently explained by our theoretical model. The expulsive force observed at the border of the shielded zone is due to energy conservation. ------------------------------------------------------------------------- NASA is conducting experiments similar to the anti-gravity shielding experiments done in Tampere Finland. A scientist named Ning Li at the University of Alabama Huntsville, is reported to be consulting with NASA. She has written some interesting articles about the relationship between superconductors and gravtiation. Here are references to some of her published articles, and a few related items: AUTHOR(s): Li, Ning and Torr, D.G. TITLE(s) Effects of a Gravitomagnetic Field on pure superconductors In: Phys. Rev.

Li and Torr, but I am told that in one of her articles, Dr Li provides the following interesting comment -- " a detectable gravitomagnetic field, and in the presence of a time-dependent applied magnetic vector potential field, a detectable gravitoelectric field could be produced" --------------------------------------------------------------------------- There is also some information about Dr Ning Li at: http://isl-garnet.uah.edu/RR93/uahmatsci.html Dr Li is with the Applied Materials Lab at the University of Alabama at Huntsville. She works closely with Dr Douglas Torr. One of their primary interests is development and production of exotic materials in a microgravity environment -- a peculiar coincidence, or maybe not, with the writing of physical theories about how to produce anti-gravity in the laboratory. Here's an unusual article from the website. --------------- Can gravity be 'made' in the laboratory? A theory that might lead to the creation of measurable manmade gravitational fields has been developed by physicists at UAH. If the theoretical work is borne out in the laboratory, it will prove that physicist Albert Einstein was correct in predicting that moving matter generates two kinds of gravitational fields: gravito-magnetic and gravito-electric. The 'artificial' gravitational field would be generated inside a container made of a superconducting material, said Dr. Douglas Torr, a research professor of physics and director of UAH's Optical Aeronomy Laboratory. "I think we can at the very least generate a microscopic field ..." If Einstein was right, the amount of gravito-magnetic energy produced by an object is proportional to its mass and its movement, explained Dr. Ning Li, a research scientist in UAH's Center for Space Plasma and Aeronomic Research. To create the artificial gravitational fields, Torr and Li propose placing a superconducting container in a magnetic field to align ions that are spinning or rotating in tiny circles inside the superconducting material. Their theory predicts the existence of ionic spin or rotation in a superconductor in a magnetic field. ------------------------------------------------------------------------ There are persistent rumors among UFO-buffs that NASA already has an operating microgravity chamber, located in Houston TX and/or Huntsville AL.

Classically the existence of equal and opposite electromagnetic fields can be ignored altogether. However, the problem can be viewed differently if we want to take into account possible quantum effects. We know that in quantum mechanics the potentials themselves may be significant and they may determine the dynamics of a particle in a region where the fields vanish. (Aharonov and Bohm 1959, Peshkin and Tonomura 1983) AN EXPERIMENT TO TEST THE GRAVITATIONAL AHARONOV-BOHM EFFECT Ho, Vu B. Morgan, Michael J. Monash University, Clayton, Victoria, Australia 1994 8 PAGES, Australian Journal of Physics (ISSN 0004-9506) vol. 47, no. 3 1994 p. 245-252 HTN-95-92507 The gravitational Aharonov-Bohm (AB) effect is examined in the weak-field approximation to general relativity. In analogy with the electromagnetic AB effect, we find that a gravitoelectromagnetic 4-vector potential gives rise to interference effects. A matter wave interferometry experiment, based on a modification of the gravity-induced quantum interference experiment of Colella, Overhauser and Werner (COW), is proposed to explicitly test the gravitoelectric version of the AB effect in a uniform gravitational field. CASI Accession Number: A95-87327 --------------------------------------------------------------------------- I recommend you get a copy of Aharonov and Bohm's classic paper "Significance of Electromagnetic Potentials in the Quantum Theory" published in The Physical Review in 1959. One of the important things that Aharonov and Bohm did was to demonstrate that the electromagnetic potentials are richer in properties than the Maxwell fields. The field is an artifical mathematical construct from which emerges the whole idea of a continuum. When you can wean yourself of this intellectual crutch you will be ready to do real physics. Both GR and QM are addicted to the same falsehood. -- Charles Cagle In the Aharonov-Bohm effect it has been determined theortically and experimentally that there is a measurable effect on a charged particle due to the electromagnetic vector potential. Which of course would be no surprise, except that the effect occurs even in areas of space where the value of the classical electromagnetic fields vanish. A quantum phase shift, detectable via particle interferometry, is found to occur due to the magnetic vector potential A. The effect on a charged particle occurs in regions which are completely shielded from classical electromagnetic fields. A dual of the Aharonov-Bohm effect is the Aharonov-Casher effect, where it is shown that measurable effects of spin-precession of a particle's magnetic moment can occur due to the electric potential, even in areas of space where the classical electrical field is completely absent. ---------------------------------------------------------------------- Prior to the revolutionary paper by Aharonov and Bohm in 1959, the importance of the electomagnetic potential and related interferometry effects, was suggested in articles by Edmund Whittaker in 1903 and 1904. And, what is now known as the Aharonov-Bohm effect, was explicitly identified in an earlier paper on electron optics by Ehrenberg and Siday in 1949. E.T. Whittaker, "On the partial differential equations of mathematical physics," Mathematische Annalen, Vol 57, 1903, pages 333-355. In this paper Whittaker demonstrates that all scalar EM potentials have an internal, organized, bidirectional EM plane-wave structure. Thus there exists an electromagnetics that is totally internal to the scalar EM potential. Since vacuum/spacetime is scalar potential, then this internal EM is in fact "internal" to the local potentialized vacuum/ spacetime. -- Tom Bearden E.T. Whittaker, "On an expression of the electromagnetic field due to electrons by means of two scalar potential functions," Proceedings of the London Mathematical Society, Series 2, Vol 1, 1904, pages 367-372. In this paper Whittaker shows that all of classical electromagnetics can be replaced by scalar potential interferometry. This ignored paper anticipated the Aharonov-Bohm (AB) effect by 55 years, and drastically extended it as well. Indeed, it prescribes a macroscopic AB effect that is distance-independent, providing a direct and engineerable mechanism for action-at-a-distance. It also provides a testable hidden-variable theory that predicts drastically new and novel effects. -- Tom Bearden W. Ehrenberg and R. W. Siday, Proc. Phys. Soc. London, B62, 8 (1949) Ten years earlier than Aharonov and Bohm, Ehrenberg and Siday formulated the science of electron optics by defining the electron refractive-index as a function of electromagnetic potential. Near the end of their paper, they discuss "a curious effect", which is exactly the AB effect. On the two sides of a magnetic flux, the vector potential has different values. This means a different refractive index for two geometrically equivalent paths. This difference in refractive index would cause an observable phase shift. -- Jun Liu ---------------------------------------------------------------------- Y. Aharonov and D. Bohm, "Significance of Electromagnetic Potentials in the Quantum Theory," Physical Review, Second Series, Vol 115 no 3, pages 485-491 (1959) Effects of potentials on charged particles exist even in the region where all the fields (and therefore the forces on the particles) vanish, contrary to classical electrodynamics. The quantum effects are due to the phenomenon of interference. These effects occur in spite of Faraday shielding. The Lorentz force does not appear anywhere in the fundamental quantum theory, but appears only as an approximation that holds in the classical limit. In QM, the fundamental physical entities are the potentials, while the fields are derived from them by differentiation.

Numerical estimate given for experimental verification. The referees disagree with each other on the existence of this effect. We study a generalization of Aharonov-Bohm effect, the potential effect. The discussion is focused on field-free effects in simply connected region, which obviously can not have any local field-flux. Among the published discussions about this kind of effects, it is generally agreed that this kind of effect does not exist due to gauge invariance. However, there are also opinions that this effect is a trivial variation of Aharonov-Bohm effect and therefore there is no need to check its existence. To my knowledge, it has never been tested. My first goal here is to supply enough theoretical reason to motivate the experimental test of this effect. I start with an intuitive derivation, then I introduce a wave-front theory as a theoretical consideration. Logically, the existence of potential effect implies the existence of the AB effect, but not vice versa. The purpose of this paper is to provide a physical connection in the opposite direction. QUANTUM PHYSICS, ABSTRACT QUANT-PH/9510004 From: "Jun Liu" Date: Thu, 5 Oct 1995 04:30:27 -0400 The Real Significance of the Electromagnetic Potentials Author(s): J`un L'iu The importance of the potential is revealed in a newly discovered effect of the potential. This paper explore the same issue introduced in quant-ph/9506038 from several different aspects including electron optics and relativity. Some people fail to recognize this effect due to a wrong application of gauge invariance. In the above two papers, Dr Liu proposes a theory of the electromagnetic potential which is a radical extension of the well known Aharonov-Bohm effect. In the second paper he is barely able to contain his frustration about repeated publication rejections over the last four years from leading physics journals. He provides a theoretical foundation for his potential theory, as well as some relatively straight forward suggestions for experiments which might confirm the theory. But there is an enormous problem. Liu's theory violates the concept of invariance of physical parameters under an electromagnetic gauge transformation. Electromagnetic gauge invariance is a cornerstone in the foundation of quantum theory and QED, and it is also part and parcel linked with the dogma of light speed invariance. In other words, heresy. The AB effect is invariant under an electromagnetic gauge transformation. While a phase-shift occurs in the AB effect, it can be identified only over a closed path and is impossible to identify with any specific "local" region of space. Furthermore, in the AB effect, there is no interaction relating to a transfer of energy or momentum. Maintaining the idea of gauge invariance is a little harder to do in the Aharonov-Casher effect, but it can be accomplished by "gauging away" the physical effects of magnetic spin precession by using a combination of factors from the classical Maxwell fields along with the electromagnetic potential. It has the look of an elaborate parlor trick, but so does most of QED. Liu's theory predicts that the electromagnetic potential acts like a kind of "refractive index" to wave propogation, and is similar in some respects to what was predicted in the earlier paper on electron optics by Ehrenberg and Siday in 1949. The result is that in some circumstances an electromagnetic potential causes a change in wavelength, and in other circumstances causes a change in phase (AB effect). An effect on wavelength would be manifested as a change in the envelope of the interference pattern, rather than merely a shift in the pattern. In Liu's theory an exchange of energy and momentum becomes possible. His theory is relatively easy to test and verify, but oddly or not, no one has yet done so. Maybe because we already "know" it can't be true? One interesting prediction of Liu's theory is that electromagnetic potential will result in time dilation. He doesn't appear to be aware that there is already experimental evidence that this occurs. See references to inventions and experiments by people such as Saxl, Barker, and Keller, which demonstrate time dilation in an electric potential. Time dilation can be viewed equivalently as a shift in wavelength. Liu wishes for someone to conduct an experiment to test for a change in wavelength by using a quantum interferometer. A fine idea. But what about those experimenters who have already measured this effect with a clock? Also see a variety of references here to theories and experiments which relate the scalar electric potential to the gravitational field, and time dilation is a well know, and experimentally verified, prediction of general relativity. The Aharonov-Bohm effect has sparked a revolution in physical thought. There are a variety of new ideas and experiments, such as verification of Liu's theory, which could soon begin to fan it to a flame. When the flame becomes sufficiently illuminating, watch the political scientists begin to scramble for a comfortable seat nearer the fire. -- Robert Stirniman -------------------------------------------------------------------- Over the last five years, there have been over 300 papers published about various aspects of Aharonov-Bohm and Aharonov-Casher effects, and quantum interferometry.

Hooper, as well as Carr, Rognerud, Jefimenko, et al, find that a electromagnetic effect which is not shieldable, and hence difficult to distinguish from gravitation, results from equal and opposite electric currents (dipole-current), and that a similar effect can also be generated by a moving magnet or a moving electric current. . Recent experiments in Tampere Finland, discover a gravitational shielding effect from a levitated rotating superconductor disk. This is similar in some respects to Hooper's invention, with the equal-and-opposite electric current being generated in a superconductor disk via the Meissner effect. . Sansbury, Volkov, Brown, Teller, Blackett, Zollner, et al, provide theoretical arguments as well as some experimental indications that equal-and-opposite electric charge (dipole-charge) is similar, or equivalent, to a static gravitational field. And that alignment of electric dipoles in matter and in vacuum polarization, can result in a force which is not shieldable, and not easily distinguishable from gravity. Conversely, it is well know that a gravitational field, an acceleration, or a mechanical force, causes a dipole moment (polarization) to occur within a dielectric material. . Wallace, Laithwaite, Barnett, et al, discover that gravitational and electromagnetic field effects occur due to alignment of the microscopic spin of quantum particles with the angular momentum spin axis of a larger macroscopic body. . Aharonov and Bohm discover that an effect can occur on an electrically charged particle due to the magnetic vector potential, in regions of space where the classic Maxwell fields vanish. Originally -- on the outside of infinitely long solenoid coil (with the magnetic field cancelled by equal-and-opposite currents). Others have conducted this experiment using a toroidal coil coated with superconductor material (generating an equal-and-opposite current) to cause the Maxwell magnetic field to vanish. A similar effect, Aharonov-Casher is disovered to occur due to the electric scalar potential, in regions of space where the Maxwell electric field vanishes. . Whittaker, and Eherenberg and Siday, have written theories which are precursors to Aharonov-Bohm, suggesting that the electromagnetic potential is a far richer and more fundamental thing than the Maxwell fields. The classical Maxwell fields are regarded as artifical abstractions. We can also note that Maxwell's theory itself, was originally much richer in variables (20 equations and 20 unknowns), before it was simplified by Gibbs and Heaviside, to the vector formlation which we know as "Maxwell's" equations. . Vu Ho authors a recent paper suggesting experiments relating the electromagnetic potential and the Aharonov-Bohm effect to gravitation. And in a more recent paper, using the mathematics of differential geometry and general relativity, Dr Ho demonstrates that gravity can be expressed mathematically as a coupling of two equal-and-opposite electromagnetic fields. . Jun Liu authors recent papers suggesting that the electromagnetic potential is of paramount importance. Liu's theory predicts that "local" effects can result from the potential in regions where the Maxwell fields vanish -- a violation of the theory of invariance under electric gauge transformations. Liu theory predicts that time dilation will occur in an electric potential. Saxl, Barker, and Keller have conducted earlier experiments which demonstrate time dilation in an electric potential. . Ning Li, a consulting scientist to NASA's Marshall Space Center, who we might presume to know something, authors papers about the relationship of gravito-electric and and gravito-magnetic forces to the electromagnetic potential, and methods for generation of gravitational effects with superconductor material. According to Dr Li -- "a detectable gravitomagnetic field, and in the presence of a time-dependent applied magnetic vector potential field, a detectable gravitoelectric field could be produced." How many clues do we need? Equal-and-opposite electric sources (dipole- charges and/or dipole-currents) appear to effect the electromagnetic potential in ways which are indistinguishable from gravitation. And you know what they say about things that look like a duck. The net sum of equal and opposite electromagnetic vectors is a zero vector, but it is NOT the same situation as no vector. For skeptics and diehards who are still having a hard time accepting the idea of electro- gravitics, here's a simple experiment. Stand on a train track between two locomotives which are pushing on you with equal force in opposite directions. You will exhibit no net motion. None the less, you may soon begin to notice that something important is happening. -- Robert Stirniman ------------------------------------------------------------------------- Jorge Pullin Wed, 1 Feb 1995 22:55:17 -0500 (EST) Matters of Gravity, a newsletter for the gravity community Author: Jorge Pullin (PSU), editor.

There is some info on the opperation of the electrokinetic apparatus. _____________________________________________________________________ The 1956 paper "The Gravitics Situation" (prepared by Gravity Rand Ltd., a division of Aviation Studies Ltd. This includes six appendices with papers by various authors including the text from T. Townsend Brown's 1929 gravitor patent. ------------------------------------------------------------------ Many documents on Gravitoelectrics/Electrogravitation refer back to the 1952 Project Winterhaven. That project is said to contain information on a Mach 3 Combat Disc. Also, have any records related to other Projects with Mr. T.T. Brown been produced. I have seen his Lab notes 1 - 3 - 4. I was looking for 2 - 5 & 6. Also, the Bahnson et al Brown lab notes during his research days at Bahnson Labs in North Carolina 1957-60 period or about. I have a poor chopped up Lab Video on the subject. I'm looking for the full video the 45 minute one. Mine is a mere 23 minutes. I have yet to track down an original document entitled: "The Flying Saucer: The Application of the Biefeld-Brown Effect to the Solution of Space Navigation" by Mason Rose. This 50's document details how a flying saucer operates. I have a copy of a re-write and it is outstanding. And I'm also looking for a document as seen on SIGHTINGS TV entitled: "PROJECT SILVER BUG" the 1955 USAF Flying Saucer Tests. Also, seeking a copy of PROJECT WINTERHAVEN by Thomas Townsend Brown on a MACH-3 Combat Disc. The British had a stake in as well as the USAF. It to is from the 1950's. -- James Hartman, CaluNET - Future Science Admin. ---------------------------------------------------------------- The Biefeld-Brown (spelling is correct) effect is described generally as the anomalous tendency of high voltage flat capacitors to display movement towards (usually) the positive pole. Effects are most often seen at potentials above 50kv. Thomas Townsend Brown held a few patents on devices using it. It's very controversial and is part of the subject of "electrogravitics", as some say that the BB effect is actually polar gravity peeking out from behind a high electrical gradient within a dielectric. Claims are that the mass of the dielectric is a factor in the magnitude of the effect as well as the capacitance and the gradient intensity. Should be fairly easy for the home-workshop experimenter to get a look at, but the difficulty seems to be in isolating the effect from ionic wind and simple electrostatic propulsive effects. Skeptics claim that those forces are all it ever was, but a few reports indicate that they may be wrong. -- Rick Monteverde, Honolulu HI ------------------------------------------------------------------------- The experiments involved freely suspended electrically charged capacitors, which were determined to possess angular momentum yet did not rotate.

LC CALL NUMBER: QC16.E5 S3 1970 -------------------------------------------------------------- >From Richard Feynman's Lectures on Physics we learn that there is intrinsic field energy and momentum density associated with a static electro-magnetic field configuration. When there is a change in the magnetic field, this field energy and momentum can be directly converted into kinetic energy and mechanical momentum. Feynman illustrates this with an electromagnetic carousel paradox. In this paradox, a dielectric disk (which is embedded with small charged spheres along its circumference) rotates without any apparent "counter" torque in the system. Before this rotation occurs, the dielectric disk is immersed in a static magnetic field. The subsequent rotation occurs as a consequence to reducing the previously static magnetic field to zero. The angular momentum and rotational kinetic energy comes directly from the initial static magnetic field. "The Feynman Lectures on Physics" by Richard Feynman, R.B. Leighton, and M.

Townsend Brown Conference: "Focus on Unconventional Energies: A Symposium on Electrical Propulsion & the Technology of Electro-Gravity" April 15-16, 1994 Philadelphia Community College, Philadelphia, PA This conference was held in tribute to Thomas Townsend Brown and I feel that it was a great success. About 15 speakers and 80 attendees provided a brief overview of Zero Point Energy theories, Free Energy devices, electrostatics theory, and antigravity experiments and documentation. Attendees came from as far away as California and Washington. The conference program advertised the following topics: "A Review of Advanced Energy Devices: Evidence, Promises, and Dangers" by Patrick Bailey (VP INE); "Thomas Townsend Brown's Electro-Gravities Research in the 1950's" by Tom Valone (Integrity Institute); "The Role of Electro-Statics" by Charles Yost (Electric Spacecraft Journal); "Thomas Townsend Brown's Research: A Challenge to Modern Science" by Elizabeth Rauscher (Tecnic Research Laboratories); "Electro-Gravitic Theory: Explaining the Operating Principle of Brown's Electric Disks" by Paul LaViolette (The Starburst Foundation); "A Panel Discussion on Biefeld-Brown and Beyond;" "Vortices in the Zero Point Energy" by Moray King; "Design of a Compact Marx Generator Triggered by a Blumlein Capacitor" by George Hathaway; "Thomas Townsend Brown's Final Gravito-Electric Research" by Josh Reynolds (New Wave Partners); "Townsend Brown Effects Reviewed" by Ron Kovac; "Pushing the Boundaries: Electro-Hydro Dynamic Potentials ..." by Henry Monteith, and "Gravity Drop Tests" by Don Kelly (SEA). - Patrick Bailey I have the audio tapes from the T.T. Brown conference, 11 tapes in all, and I got a lot of good information from it. - Bob Reim (reim@advantor.com) ----------------------------------------------------------------------------- There is a connection between Townsend Brown and UFOs. Brown was the founder of NICAP (National Investigations Committee on Aerial Phenomena) Project Skylight, and Brown served as Vice Chairman pro tempore during during NICAP's organizational period in 1956.

Also, there was a T.T. Brown on the Condon committee for UFO studies. And some of Brown's above described Navy duties are coincident with some of the times and places in stories about the Montauk Project/ Philadelphia Experiment. ----------------------------------------------------------------------- Quotation from a letter to William Moore from T. Townsend Brown dated 12/17/76 -- "I am still working on petroelectricity and the project is housed largely at Stanford Research Institute with additional assistance being provided by the University of California - Berkeley and the Ames Research center of NASA. Unfortunately, under the circumstances, while this project is being evaluated for funding by ERDA we should not and cannot publish details..." "Your next question concerns the airfoils. As far as I am aware, no rf is radiated. There is, of course, a static d.c. field which accompanies the airfoils in flight." ------------------------------------------------------------------------ It is very interesting to note that Townsend Brown was the pioneer in this field, and was not able to obtain very much support for his work until the 1950's. During that time, there was much discussion of gravity and antigravity within the aerospace industry and in the magazine "Aviation Week." Then the Gravity Research Group (GRG) published a detailed summary report of their review of research into "Electrostatic Motion, Dynamic Counterbary, and Barycentric Control" (i.e. "Antigravity"). This report is the last public report that any researchers have been able to find for us that deals with the physical effects of electrostatics, electrodynamics, and gravity control. (It is also worth noting that this report was found in the Wright Patterson Air Force Base Library "TL 565 A9" and was not listed in the library catalog). So, after the mid-1950's to the present, no other information regarding the technology of electrodynamics and its effect on gravity has been able to be found in any of the un-classified U.S. literature. - Patrick Bailey --------------------------------------------------------------------------- I have the FIVE (5) lab books of TT Brown's R&D at the Bahnson Co. in Salem, N. Carolina 1958-9. I also have some other letters and drawings of the lab plus the only surviving 16mm colour film of the various stages of his work at Bahnson Labs. I was in contact with Dr Brown in 1983 by phone and by mail. He died of lung cancer not long after in Oct of 1985. He told me that a lot of people including Bill Morre had attributed more to his work than he had really done. In particular, he was only marginally connected with the Philadelphia Experiment as such. His main theme of R&D was dielectrics and the Biefeld-Brown effect. He was not an electromagnetics man... only electrostatics. From 1983 to 1991 or so I was in frequent communication with J. Frank King who was TT Brown's boss at the Bahnson Co. J. Frank was a good man and a good friend of mine. He, too, died in Dec 1989. Before he died I was given rights to reproduce and share letters, files, drawings, patent submissions, films etc from his personal files on TT Brown, George Adamski, Dr Ilka, T Henry Moray and others. J Frank warned me a long time ago to take what TT Brown said with a 'grain of salt' because Townsend had a habit of 'stretching the truth' a bit to get funding which he was always in need of.... So, I warn you now in good faith: If you seek lost or hidden technology in Brown's lab notes, I don't think you will find it there; however, I am prepared to make photocopies available to you. There are about 750 pages in all. I would need to charge you AUS$50 per notebook which would include the air mail charges as well. In US$ that would be about US$38 per notebook. The film is available as are the notebooks (I think) from The Electric Spacecraft Journal in the US (Charles Yost on 704-252-8083, FAX 202-683-3511. -- Stan Deyo -------------------------------------------------------------------------- As far as I know, the last thing Brown published before his death was, "On The Possibilities of Optical-Frequency Gravitational Radiation", 2/14/1976 and 8/30/1976. I don't know where it was originally published. But you can get copy from: Rex Research, P.O. Box 19250, Jean NV 89019 It is part of NR 046-BT2/B17-BRV "T. Brown: Petro-Voltaics" (Gravito-Electric Conversion).

Moore. In UFO Report magazine. Unfortunately the issue date is not on this copy, and the magazine is at work. A lot of the same information can be found in the book "The Philadelphia Experiment: Project Invisibility" by William L. Moore with Charles Berlitz. Chapter 10 "The Force Fields of Townsend Brown".

The first starts from a first order lagrangian formulation, the second from a hamiltonian formulation. In this note we show that they lead to identical results for the specific cases of pure gravity with or without a cosmological constant. Paper: hep-th/9210110 (Phys. Rev. D47, R5214 (1993).)

Pullin, 13pp. no figures. We propose a naive unification of Electromagnetism and General Relativity based on enlarging the gauge group of Ashtekar's new variables. We construct the connection and loop representations and analyze the space of states. In the loop representation, the wavefunctions depend on two loops, each of them carrying information about both gravitation and electromagnetism. We find that the Chern-Simons form and the Jones Polynomial play a role in the model.

I show that the gravitational scattering amplitudes of a spin-5/2 field with mass $m\ll M_{Pl}$ violate tree-level unitarity at energies $\sqrt{s}\approx\sqrt{mM_{Pl}}$ if the coupling to gravity is minimal. Unitarity up to energies $\sqrt{s}\approx M_{Pl}$ is restored by adding a suitable non-minimal term, which gives rise to interactions violating the (strong) equivalence principle. These interactions are only relevant at distances $d\lequiv 1/m$.

We assume further that the electromagnetic field tensor, $F_{ab}$, is invariant under the action of the isometry group induced by $\xi^a$. It is proved that whenever the two potentials associated with the electromagnetic field are functionally independent the entire content of Maxwell's equations is equivalent to the relation $\n^aT_{ab}=0$. Since this relation is implied by Einstein's equation we argue that it is enough to solve merely Einstein's equation for these electrovac spacetimes because the relevant equations of motion will be satisfied automatically. It is also shown that for the exceptional case of functionally related potentials $\n^aT_{ab}=0$ implies along with one of the relevant equations of motion that the complementary equation concerning the electromagnetic field is satisfied.

Soleng, 10 pages, LaTeX, Report: UPR-0540-T, To appear in Physica Scripta. The gravitational effect of vacuum polarization in space exterior to a particle in (2+1)-dimensional Einstein theory is investigated. In the weak field limit this gravitational field corresponds to an inverse square law of gravitational attraction, even though the gravitational mass of the quantum vacuum is negative. The paradox is resolved by considering a particle of finite extension and taking into account the vacuum polarization in its interior.

The phenomenon of gyroscopic precession is studied within the framework of Frenet-Serret formalism adapted to quasi-Killing trajectories. Its relation to the congruence vorticity is highlighted with particular reference to the irrotational congruence admitted by the stationary, axisymmetric spacetime. General precession formulae are obtained for circular orbits with arbitrary constant angular speeds. By successive reduction, different types of precessions are derived for the Kerr - Schwarzschild - Minkowski spacetime family. The phenomenon is studied in the case of other interesting spacetimes, such as the De Sitter and Godel universes as well as the general stationary, cylindrical, vacuum spacetimes.

V.Khatsymovsky, 10 pages, Plain LaTeX, preprint UUITP-20/1993 Renormalized vacuum expectation values of electromagnetic stress-energy tensor are calculated in the background spherically-symmetrical metric of the wormhole's topology. Covariant geodesic point separation method of regularization is used. Violation of the weak energy condition at the throat of wormhole takes place for geometry sufficiently close to that of infinitely long wormhole of constant radius irrespectively of the detailed form of metric. This is an argument in favour of possibility of existence of selfconsistent wormhole in empty space maintained by vacuum field fluctuations in the wormhole's background.

By David Garfinkle and M.A. Melvin. 17 pages In this paper we apply the techniques which have been developed over the last few decades for generating nontrivially new solutions of the Einstein-Maxwell equations from seed solutions for simple spacetimes. The simple seed spacetime which we choose is the "magnetic universe" to which we apply the Ehlers transformation. Three interesting non-singular metrics are generated. Two of these may be described as "rotating magnetic universes" and the third as an "evolving magnetic universe." Each is causally complete - in that all timelike and lightlike geodesics do not end in a finite time or affine parameter. We also give the electromagnetic field in each case. For the two rotating stationary cases we give the projection with respect to a stationary observer of the electromagnetic field into electric and magnetic components. Paper: gr-qc/9404065 (Phys. Rev.

Carroll, Edward Farhi, Alan H. Guth, and Ken D. Olum. Plain TeX, 41 pages incl. 9 figures. MIT-CTP #2252. The discovery by Gott of a remarkably simple spacetime with closed timelike curves (CTC's) provides a tool for investigating how the creation of time machines is prevented in classical general relativity. The Gott spacetime contains two infinitely long, parallel cosmic strings, which can equivalently be viewed as point masses in (2+1)-dimensional gravity. We examine the possibility of building such a time machine in an open universe. Specifically, we consider initial data specified on an edgeless, noncompact, spacelike hypersurface, for which the total momentum is timelike (i.e., not the momentum of a Gott spacetime). In contrast to the case of a closed universe (in which Gott pairs, although not CTC's, can be produced from the decay of stationary particles), we find that there is never enough energy for a Gott-like time machine to evolve from the specified data; it is impossible to accelerate two particles to sufficiently high velocity. Thus, the no-CTC theorems of Tipler and Hawking are enforced in an open (2+1)-dimensional universe by a mechanism different from that which operates in a closed universe. In proving our result, we develop a simple method to understand the inequalities that restrict the result of combining momenta in (2+1)-dimensional gravity.

We revisit the long standing problem of analyzing an inertial electric charge from the point of view of uniformly accelerated observers in the context of semi-classical gravity. We choose a suitable set of accelerated observers with respect to which there is no photon emission coming from the inertial charge. We discuss this result against previous claims [F. Rohrlich, Ann.

Matzner, Warner A. Miller and Brian W. Tolman, 16 pages, RevTeX, LA-UR-94-1289. (Part I of II, postscript figures in Part II). LAGEOS is an accurately-tracked, dense spherical satellite covered with 426 retroreflectors. The tracking accuracy is such as to yield a medium term (years to decades) inertial reference frame determined via relatively inexpensive observations. This frame is used as an adjunct to the more difficult and data intensive VLBI absolute frame measurements. There is a substantial secular precession of the satellite's line of nodes consistent with the classical, Newtonian precession due to the non-sphericity of the earth. Ciufolini has suggested the launch of an identical satellite (LAGEOS-3) into an orbit supplementary to that of LAGEOS-1: LAGEOS-3 would then experience an equal and opposite classical precession to that of LAGEOS-1. Besides providing a more accurate real-time measurement of the earth's length of day and polar wobble, this paired-satellite experiment would provide the first direct measurement of the general relativistic frame-dragging effect. Of the five dominant error sources in this experiment, the largest one involves surface forces on the satellite, and their consequent impact on the orbital nodal precession. The surface forces are a function of the spin dynamics of the satellite. Consequently, we undertake here a theoretical effort to model the spin ndynamics of LAGEOS. In this paper we present our preliminary results. Paper: gr-qc/9407003 From: William Bruckman Date: Tue, 5 Jul 94 09:06:49 EDT Generation of Electro and Magneto Static Solutions of the Scalar-Tensor Theories of Gravity, William Bruckman, 28 pages, LaTeX. The field equations of the scalar-tensor theories of gravitation are presented in different representations, related to each other by conformal transformations of the metric. One of the representations resembles the Jordan-Brans-Dicke theory, and is the starting point for the generation of exact electrostatic and magnetostatic exterior solutions. The corresponding solutions for each specific theory can be obtained by transforming back to the original canonical representation, and the conversions are given for the theories of Jordan-Brans-Dicke, Barker, Schwinger, and conformally invariant coupling. The electrostatic solutions represent the exterior metrics and fields of configurations where the gravitational and electric equipotential surfaces have the same symmetry. A particular family of electrostatic solutions is developed, which includes as special case the spherically symmetric solutions of the scalar-tensor theories. As expected, they reduce to the well-known Reissner-Nordstrom metric when the scalar field is set equal to a constant. The analysis of the Jordan-Brans-Dicke metric yields an upper bound for the mass-radius ratio of static stars, for a class of interior structures.

Since the electric charge can be viewed as electric lines of force trapped in a finite region of spacetime, these solutions can be interpreted as the quantum corresponding of the Ein-stein--Rosen--Misner--Wheeler electromagnetic geon.

H. Soleng and O. Gron, 27 pages, compressed and uuencoded postscript file with unpacking instructions; major revision to section IV.D.2 on pages 15-16 ("Corrections to the Coulomb potential at short distances") and to the figure on page 27, to be published in The Annals of Physics (NY), NORDITA 94/50 In four dimensions a Gauss-Bonnet term in the action corresponds to a total derivative, and it does not contribute to the classical equations of motion. For higher-dimensional geometries this term has the interesting property (shared with other dimensionally continued Euler densities) that when the action is varied with respect to the metric, it gives rise to a symmetric, covariantly conserved tensor of rank two which is a function of the metric and its first and second order derivatives. Here we review the unification of General Relativity and electromagnetism in the classical five-dimensional, restricted (with g55 = 1) Kaluza-Klein model. Then we discuss the modifications of the Einstein-Maxwell theory that results from adding the Gauss-Bonnet term in the action. The resulting four-dimensional theory describes a non-linear U(1) gauge theory non-minimally coupled to gravity. For a point charge at rest, we find a perturbative solution for large distances which gives a mass-dependent correction to the Coulomb potential. Near the source we find a power-law solution which seems to cure the short-distance divergency of the Coulomb potential. Possible ways to obtain an experimental upper limit to the coupling of the hypothetical Gauss-Bonnet term are also considered. Paper: hep-th/9410046 From: M.J. Duff Date: Fri, 7 Oct 94 13:04:15 BST KALUZA-KLEIN THEORY IN PERSPECTIVE, M. J. Duff, 38 pages latex, NI-94-015 The Kaluza-Klein idea of extra spacetime dimensions continues to pervade current attempts to unify the fundamental forces, but in ways somewhat different from that originally envisaged. We present a modern perspective on the role of internal dimensions in physics, focussing in particular on superstring theory. A novel result is the interpretation of Kaluza-Klein string states as extreme black holes.(Talk delivered at the Oskar Klein Centenary Nobel Symposium, Stockholm, September 19-21, 1994.)

General Relativity and Gravitation, Vol 23 No 1, 1991 Recently it has been shown that, if sources are appended in a certain way to the field equations of Einstein's unified theory, the contracted Bianchi identities and the field operations appear endowed with definite physical meaning. The theory looks like a gravoelectrodynamics in a polarizable Riemmannian continuum. The wealth of the implied possibilities is far richer than in the so-called Einstein-Maxwell theory. --------------------------------------------------------------------------- Paper: HEP-TH/9411092 From: hssong@phyy.snu.ac.kr Date: Mon, 14 Nov 94 15:19:29 KST Title: Factorization and polarization in linearized gravity Authors: S.Y.

Song Comments: 45 pages, figures are included (uses pictex), RevTex Report-no: KEK-TH-415, HYUPT-94/10, SNUTP 94-03, We investigate all the four-body graviton interaction processes: gX -> gamma X, gX -> gX, and gg -> gg, with X as an elementary particle of spin less than two in the context of linearized gravity except the spin-3/2 case. We show explicitly that gravitational gauge invariance and Lorentz invariance cause every four-body graviton scattering amplitude to be factorized. We explore the implications of this factorization property by investigating polarization effects through the covariant density matrix formalism in each four-body graviton scattering process. ------------------------------------------------------------------------- Causality, electromagnetic induction, and gravitation : a different approach to the theory of electromagnetic and gravitational fields/ Oleg D.

Holt from NASA Johnson Space Center to the American Institute of Aeronautics and Astronautics' 16th Joint Propulsion Conference, June 30-July 2, 1980. Holt presents a project using an already existing system known as the Coherent Field and Energy Resonance System (CoFERS) [probably located at Los Alamos Labs' High Magnetic Field Research Laboratory]. CoFERS utilizes a toroidal-shaped energy guide with megagauss magnetic field sources located along radius vectors equally spaced around the toroid. CoFERS is shaped like a thick flying disc. Holt goes on to say: "By converying an object's normal space-time energy pattern to an energy pattern which differs substantially from the normal pattern, the gravitational forces acting on the object are changed. The object's new pattern interacts with the surrounding space-time and virtual energy patterns, such that the interactive forces are substantially altered. The alteration of the characteristics of the continuous field of force results in the apparent motion of the object *through space-time*." [...] "Since the gravitational forces acting on the propulsion system can be quickly altered to achieve the desired motion, the *spacecraft* can make right-angle turns at very-high velocities without adversely affecting the crew or system elements. The effective gravitational field the *spacecraft/ aircraft* experiences can be nearly simultaneously reoriented at a 90- degree angle, resulting in a smooth continuous motion as far as the occupants are concerned." [ ... ] "The gravimagnetic system is perhaps best suited for use in and around ... a large mass such as the Earth." "While the gravimagnetic system is likely to be the first field-dependent propulsion system developed, the field resonance system will **bring stellar and galactic travel out of the realm of science fiction**. The field resonance system artificially generates an energy pattern which precisely matches or resonates with a virtual pattern associated with a distent space-time point. According to the model, if a fundamental or precise resonance is established, (using hydromagnetic wave fine-tuning techniques), the spacecraft will be very strongly and equally repelled by surrounding virtual patterns. At the same time, through the virtual many-dimensional structure of space-time, a very strong attraction with the virtual pattern of a distant space-time point will exist. ...this combination of very strong forces will result in the translocation of the spacecraft from its initial position through the many-dimensional virtual structure to the distant space-time point.

We show that, in some configurations, the coherent interaction of the wave with both the mechanical oscillator and the RLC circuit gives rise to a mechanical quality factor increase of the electromagnetic signal. When this system is used as an amplifier of gravitational periodic signals a sensitivity of $10^{-30}$ on the amplitude of the metric could be achieved.

Khriplovich, A.A. Pomeransky Spin-orbit and spin-spin effects in the gravitational interaction are treated in a close analogy with the fine and hyperfine interactions in atoms. The proper definition of the cener-of-mass coordinate is discussed. The technique developed is applied then to the gravitational radiation of compact binary stars. Our result for the spin-orbit correction differs from that obtained by other authors. New effects possible for the motion of a spinning particle in a gravitational field are pointed out. The corresponding corrections, nonlinear in spin, are in principle of the same order of magnitude as the ordinary spin-spin interaction.

Chaichian , R. Gonzalez Felipe , D. Louis Martinez The Hamiltonian formulation of the motion of a spinning relativistic particle in an external electromagnetic field is considered. The approach is based on the introduction of new coordinates and their conjugated momenta to describe the spin degrees of freedom together with an appropriate set of constraints in the Dirac formulation. For particles with gyromagnetic ratio $g=2$, the equations of motion do not predict any deviation from the standard Lorentz force, while for $g \neq 2$ an additional force, which corresponds to the magnetic dipole force, is obtained.

Comments: Invited Lectures at the International School of Nucleon Spin Structure, Erice, August 1995. The recent series of experiments on polarized lepton-nucleon scattering have provided a strange new twist in the story of the nucleon, some of whose aspects are reviewed in these lectures. In the first lecture, we review some issues arising in the analysis of the data on polarized structure functions, focusing in particular on the importance and treatment of high-order QCD perturbation theory. In the second lecture some possible interpretations of the ``EMC spin effect" are reviewed, principally in the chiral soliton (Skyrmion) approach, but also interpretations related to the axial $U(1)$ anomaly. This lecture also discusses other indications from recent LEAR data for an $\bar{s} s$ component in the nucleon wave function, and discusses test of a model for this component. Finally, the third lecture reviews the implications of polarized structure functions measurements for experiments to search for cold dark matter particles, such as the lightest supersymmetric particle and the axion, after reviewing briefly the astrophysical and cosmological evidence for cold dark matter. ---------------------------------------------------------------------- "Mechanical Propulsion From Unsymmetrical Magnetic Induction Fields" by: R.L. Schlicher A.W. Biggs W.J. Tedeschi 31st AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit, July 10-12 1995 A method is presented for generating mechanical spacecraft propulsion from unsymmetrical magnetic induction fields. It is based on an unsymmetrical three-dimensional loop antenna structure driven by a repetitively-pulsed high-current power supply. Antenna geometry is optimized for generating propulsive thrust rather than radiating electromagnetic energy. A magnetic field density gradient imbalances the magneto-mechanical forces that result from the interations of the internal magnetic induction field with the current in the conductors of the antenna structure. From Richard Feynman's Lectures on Physics we learn that there is intrinsic field energy and momentum density associated with a static electro-magnetic field configuration. When there is a change in the magnetic field, this field energy and momentum can be directly converted into kinetic energy and mechanical momentum. Feynman illustrates this with an electromagnetic carousel paradox. In this paradox, a dielectric disk (which is embedded with small charged spheres along its circumference) rotates without any apparent "counter" torque in the system. Before this rotation occurs, the dielectric disk is immersed in a static magnetic field. The subsequent rotation occurs as a consequence to reducing the previously static magnetic field to zero. The angular momentum and rotational kinetic energy comes directly from the initial static magnetic field. "The Feynman Lectures on Physics" by Richard Feynman, R.B. Leighton, and M.

Schlicher et al. 1992 -------------------------------------------------------------------------- Dr Peter Graneau has conducted experiments which he claims provide a demonstration of departure from classical electrodynamics at high currents levels. A force is found to exist in a direction longitudinal to current flow. Graneau ran a variety of types of experiments with a metal rod conductor immersed in a conductive fluid (mercury, or saline solution). With high amperage passing through the solution the metal rod is found to move in a longitudinal direction. There is no known explanation in conventional EM theory. This force may be similar to the force (v X B) that William Hooper finds in a noninductive coil. Or Graneau's longitudinal force may be a coupling between the electromagnetic and inertial/gravitational fields, which is predicted by some 5-D unified EM/gravitational theories -- predicted to result from a divergence of the electric current vector field. Graneau's experiments should be relatively easy to duplicate. I can find no record that anyone has ever done so. Graneau has also discovered apparently anomalous forces and effects in high energy electromechanical devices such as rail guns and induction motors. AUTHOR: Graneau, Peter.

I looked a bit into this phenomena in 1994. I will now be able look a bit further. It seems that Graneau beleives in free energy in vacuum. The railgun and the theories about it are very controversial. There is a conflict between PhD Witalis, who works for the Swedish Defense, and the established plasmaphysiscists here in Uppsala. Witalis has condemned controlled hot fusion. -- David Jo
