Edward Teller, "Electromagnetism and Gravitation", Proceeds of the National Academy of Science, Vol 74 No 4, Pages 2664-2666. In this paper Dr Teller suggests some clues about the coupling between electromagnetism and gravitation. In the first part of his paper Teller describes how an electric field due to polarization can be induced in a dielectric material which is subject to angular or linear acceleration, or if subject to a gravitational field. In the second part of the paper Teller describes, using purely dimenensional analysis, how a magnetic field might be produced by a spinning mass. He also comments that the magnitude of this magnetic field might be exceedingly small, and notes that a "numerical" factor could exist which might act to increase the magnitude of the field. (Note: It is speculated by others that alignment of microscopic particles with the macroscopic spin axis of the earth, could result in a large "numerical" factor. Fact is, the earth does have a fairly large measurable magnetic field, about which there are a variety of theories as to the origin.) ---------------------------------------------------------------------- Paper: hep-th/9506049 From: HORIE@dipmza.physik.Uni-Mainz.DE Date: Thu, 08 Jun 1995 11:23:23 +0100 Title: New Insight into the Relation between Torsion and Electromagnetism Author: Kenichi Horie (Mainz Univ.) Report-no: MZ/TH 95-16 In several unified field theories the torsion trace is set equal to the electromagnetic potential. Using fibre bundle techniques we show that this is no leading principle but a formal consequence of another geometric relation between space-time and electromagentism. HIGH ENERGY PHYSICS - THEORY, ABSTRACT HEP-TH/9409018 From: HORIE@VIPMZw.physik.Uni-Mainz.DE Date: Sat, 03 Sep 1994 10:27:48 +0100 GEOMETRIC INTERPRETATION OF ELECTROMAGNETISM IN A GRAVITATIONAL THEORY WITH SPACE--TIME TORSION BY KENICHI HORIE, INSTITUT FUR PHYSIK, JOHANNES GUTENBERG- -UNIVERSIT"AT MAINZ, D--55099 MAINZ, GERMANY, A complete geometric unification of gravity and electromagnetism is proposed by considering two aspects of torsion: its relation to spin established in Einstein--Cartan theory and the possible interpretation of the torsion trace as the electromagnetic potential. Starting with a Lagrangian built of Dirac spinors, orthonormal tetrads, and a complex rather than a real linear connection we define an extended spinor derivative by which we obtain not only a very natural unification, but can also fully clarify the nontrivial underlying fibre bundle structure. Thereby a new type of contact interaction between spinors emerges, which differs from the usual one in Einstein--Cartan theory. The splitting of the linear connection into a metric and an electromagnetic part together with a characteristic length scale in the theory strongly suggest that gravity and electromagnetism have the same geometrical origin. "Gauge Invariant Electromagnetic Coupling with Torsion Potential", Richard T. Hammond, General Relativity and Gravitation, Vol 23 No 11 1991 Electromagnetism is coupled to torsion in a gauge invariant manner by relaxing minimal coupling and introducting into the Lagrangian a term bilinear the electromagnetic field tensor and its torsion potential. The resulting coupling between electromagnetism and torsion is examined and a solution corresponding to traveling coupled waves is given. Since torsion is usually regarded as resuting from the spin of a body, this might establish a classical relationship between charge and spin. The results suggest that the effect should be looked for in high intensity electric fields of low frequency. "Detecting Torsion from Massive Electrodynamics", L.C. Garcia de Andrade, and M. Lopes, General Relativity and Gravitation, Vol 25 No 11 1993 A new method of detecting torsion in the case of massive electrodynamics is proposed. Several authors have proposed methods for the detection of torsion in theories of the Einstein-Cartan type, and also in theories where the torsion field propogates. These theories are based on the studies of Dirac test particles, which have spin like the electron, and the gyroscope-like precession of these atomic particles. The interaction energy between the torsion vector Q, and an electric dipole p, is given by (p dot Q). AUTHOR(s): de Andrade, L.C. Garcia TITLE(s): Electron gyroscopes to test torsion gravity?

CARROLL AND GEORGE B. FIELD, 16 PAGES PLUS ONE FIGURE (PLAIN TEX), MIT-CTP #2291. We discuss the possibility of constraining theories of gravity in which the connection is a fundamental variable by searching for observational consequences of the torsion degrees of freedom. In a wide class of models, the only modes of the torsion tensor which interact with matter are either a massive scalar or a massive spin-1 boson. Focusing on the scalar version, we study constraints on the two-dimensional parameter space characterizing the theory. For reasonable choices of these parameters the torsion decays quickly into matter fields, and no long-range fields are generated which could be discovered by ground-based or astrophysical experiments. --------------------- ------------------------------------------------------ GENERAL RELATIVITY & QUANTUM COSMOLOGY, ABSTRACT GR-QC/9304047 From: KUBYSHIN%EBUBECM1.BITNET@FRMOP11.CNUSC.FR Date: Sun, 02 May 93 12:55:30 BCN INVARIANT CONNECTIONS WITH TORSION ON GROUP MANIFOLDS AND THEIR APPLICATION IN KALUZA-KLEIN THEORIES, KUBYSHIN YU.A., MALYSHENKO V.O.

This result is used for the dimensional reduction in a theory of multidimensional gravity with curvature squared terms on M^{4} times S. We calculate the potential of scalar fields, emerging from extra components of the metric and torsion, and analyze the role of the torsion for the stability of spontaneous compactification. ------------ -------------------------------------------------------------- Subject: Antigravity in Jane's From: "Terry Colvin"Go to the Next RS EG Refs. Page"All those interested in advanced propulsion concepts should check out Jane's Defence Weekly, 10 June 1995. An article discusses anti-gravity schemes and shows drawings of sauceroid vehicles from British Aerospace among others. Area 51 is mentioned, as well as an unclassified paper done for the USAF by Science Applications International Corp. in 1990. The subject was [Electric Propulsion], a[n] euphemism for anti-gravity according to Jane's. Michael Flora" -------------------------------------------------------------------- Anti-Gravity for Real -- Discussed in Jane's Defence Weekly Jane's Defence Weekly is a most respected journal in the defense industry. Jane's has often been the first to break the news about secret development of radically new technologies and equipment. Jane's Defence Weekly of 10 June 1995, has an article about advanced aerospace technologies, written by Nick Cook. The idea of anti-gravity is taken seriously and is auspicously present throughout the article -- including three artist renditions of future anti-gravity based craft. The Jane's article commences with a mention of anti-gravity technology, and also ends with a few paragraphs discussing anti-gravity. In between is the bulk of the article, which consists of discussion of "conventional" subjects, including: Hypersonics, Gas Turbine Inrements, The Super Cockpit, and Stealth. At the start of the Jane's article there is some information from the Gravity Rand Report on Electrogravitics which was done for the USAF in 1956, and was recently declassified. Here's an excerpt from the beginning of the Jane's article. Take this example from a specialist US aviation magazine in 1956. "We're already working with equipment to cancel out gravity," Lawrence D Bell, founder of the company that bears his name was quoted as saying. Bell, apparently, was not the only one working in this field. Others said to be seeking to master this arcane 'science' included the Glenn L Martin Company, Convair, Lear, and Sperry Gyroscope. Within a few years we were assured, aircraft, cars, submarines and power stations would all be driven by this radical new propulsion technology. Sadly it was not to be. Here's the ending section of the Jane's article. BEYOND 2001 Groom Lake Nevada is the epicentre of classified USAF research into Stealth and other exotic aerospace technologies. Several years after the collapse of the Soviet threat, activity and investment at this remote, highly secret air base (so secret its prescence is, as yet, unacknowledged by the US government) is still on the increase. While research into less sensitive technologies such two-dimensional thrust-vectoring and advanced short take-off and vertical landing (ASTOVL) are pursued in the open at nearby Edwards AFB in California, Groom Lake is set to hang onto its secrets. The USAF's recent confiscation of 1600 acres of public land bordering the facility is consistent with the Pentagon's desire to maintain its lead in quantum leap technologies -- some of which, according to well qualified observers in and around the Nevada area, defy current thinking into the predicted direction of aerospace engineering. That aerospace ocmpanies continue to look at highly radical alternative air vehicle concepts is evidence of the ongoing quest for breakthrough designs. Glimpses into this world are rare, but provide some insight into likely 21st century research activity. The 1990 unclassified 'Electric Propulsion Study' (a quest for antigravity propulsion system by another name) conducted by the USA's Science Application International Corp (SAIC) on behalf of USAF's then Astronautics Laboratory at Edwards AFB shows that USAF visionaries are still being given free reign. Until recently BAe (British Aerospace) also provided internal resources for its own anti-gravity studies and even went so far as to outline this thinking with artists' concepts -- a case of Lawrence Bell's vision perhaps being not so wide of the mark after all. Before he died, Ben Rich, who headed Lockheed's Skunk Works from 1975-1991, was quoted as saying: "We have some new things. We are not stagnating. What we are doing is updating ourselves, without advertising. There are some new programmes, and there are certain things -- some of them 20 to 30 years old -- that are still breakthroughs and appropriate to keep quiet about. Other people don't have them yet. Thirty years from now, we may still not know the half of what is currently being tested in and around Groom Lake.

FEB 01 1994 v 11 n 2 Page 371 ----------------------------------------------------------------------- It might interest antigravity researchers to know (for those not already aware) that Professor ER Laithwaite, a respected British electrical engineer, has been doing work on this very subject for decades, but when he tried to demonstrate the viability of his theories to his peers their closed minds closed ranks and ridiculed his efforts as fantasy. Laithwaite lost cred with the scientific community and had to rely just on one or two close associates in semi-secrecy. A recent (a year or two ago) series of TV programmes in Britain (on controversial scientific discoveries that have yet to accepted by the scientific establishment as worthy of further research and funding) ran an episode on Laithwaite. He claimed that gyroscopes could transfer mass. I know of one book he wrote: Transport Without Wheels published by Paul Elek in 1977 ISBN 0236400665 (info from an old note I made) though this is NOT specifically about his antigravity theories (I remember that it concentrated on propulsion via electrical rails) I would be most interested in learning about anything he (or anyone else) might have written specifically on his antigravity work. - George Szaszvari "Propulsion by Gyro", Eric Laithwaite, Space, Sep 1989 Vol 5 No 5 In an attempt to reveal the strange, hidden properties of gyroscopes, Professor Eric Laithwaite explains the physics behind the idea that a propulsion system could be built using gyros. -------------------------------- ------------------------------------------
