United States gravity control propulsion initiative

From Wikipedia, the free encyclopedia

The gravity control propulsion initiative was a nation-wide collection of classified projects: they were aimed to develop and discover technologies and theories for the manipulation of gravity or gravity-like fields for propulsion.[1] Although general relativity theory appeared to prohibit anti-gravity propulsion, several programs were funded to develop it through gravitation research from 1955 to 1973. The names of many contributors to general relativity and those of the golden age of general relativity have appeared among documents about institutions that had served as the theoretical research components of the initiative.[2][3][4] The existence and 1950s emergence of the initiative has not been a subject of controversy for aerospace writers, critics, and conspiracy theory advocates. But its rationale, effectiveness, and longevity have been the objects of contested views.

Contents

[edit] Evidence of existence

Mainstream newspapers, popular magazines, technical journals, and declassified reports have served as evidence for the existence of the gravity control propulsion initiative. It has not been evinced by any technological artifacts, such as the Project Pluto Tory IIA, the world's first nuclear ramjet. Commemorative monuments by the Gravity Research Foundation have been the artifacts attesting to the early commitments to developing gravity manipulation. The writings about the initiative had disclosed the “players” and resources while prudently withholding both the specific features of the research and the identity of its coordinating body. Publicized and telecasted conspiracy theory anecdotes have suggested much higher levels of success to the initiative than mainstream science.

[edit] Histories

Recent historical analysis and reports have attracted attention to the agencies and firms that had participated in the gravity control propulsion initiative. James E. Allen, BAE Systems consultant and engineering professor at Kingston University, included the initiative in his history of novel propulsion systems for the journal Progress in Aerospace Sciences.[5] Research by Dr. David Kaiser, Associate Professor of the History of Science, Massachusetts Institute of Technology, manifested the contributions made by the Gravity Research Foundation to the pedagogical aspects of the golden age of general relativity.[2] Dr. Joshua Goldberg, Syracuse University, described the Air Force's support of relativity research during that period.[3] Progress reports[4] and anecdotes and Internet resumes of former visiting and staff scientists have been the sources of the history of the Research Institute for Advanced Study (RIAS). Former aviation editor of Jane's Defense Weekly, Nick Cook, drew attention to the initiative through worldwide publications of his book,[6] The Hunt for Zero Point, and subsequent televised documentaries. Mainstream historical accounts of the initiative have been supplemented with conspiracy theory anecdotes.

[edit] Contemporaneous literature

Lists of the research institutes, industrial sites, and policy makers along with statements from prominent physicists were provided in five comprehensive works that had been published during the early years of the initiative. Aviation Studies (International) Limited, London, published a detailed report about the initiative by the Gravity Research Group that was later declassified.[1] The Journal of the British Interplanetary Society and The Aeroplane published the propulsion survey and critical assessment of the initiative by the internationally recognized astronautics historian A. V. Cleaver.[7] The New York Herald Tribune and Miami Herald published a series of three articles by one of the world's greatest aviation journalist of the Twentieth Century, Ansel Talbert.[8] Talbert's two series of newspaper articles took place in the midst of the policy by press release era. Neither his nor the writings that followed the five prominent works from that period yielded denials and/or retractions.

[edit] UFO and conspiracy theory literature

The initiative has been the subject of widely published UFO and conspiracy theory literature. The documented testimonies of whistleblowers edited by Dr. Steven Greer, Director of the Disclosure Project;[9] anecdotes and schematics by Mark McCandlish and Milton William Cooper;[9][10] and the reports by Philip J. Corso,[11] David Darlington,[12] and Donald Keyhoe,[13] famous UFO researcher, have suggested incorporation of reverse engineering of recovered extraterrestrial vehicles with the anti-gravity propulsion projects had enabled the initiative to continue beyond 1973 to successfully manufacture gravity control propulsion vehicles. Branches of the military and defense agencies have denied and refuted such claims.

[edit] Theoretical research agencies

Talbert indicated the rationale for creating the initiative stemmed from the works of three physicists.[8] They were Dr. Bryce DeWitt's prize-winning Gravity Research Foundation essay;[14] the book Gravity and the Universe by Dr. Pascual Jordan; and presentations to the International Astronautical Federation by Dr. Burkhard Heim.[15][16] Physical principle surveys by Cleaver and Weyle stated the initiative was not based on any recognized theoretical breakthroughs. Cleaver's skepticism suggested an alternative rationale for establishing the initiative based on a science fiction novel.[7] Weyl charged publishers with poor journalism; attacked their terminology; and gave the highest rating of prospective physical principles for gravity control propulsion to Burkhard Heim's works.[15] Stambler leveled harsh criticisms against Gluraheff's gravitation hypothesis.[17] Talbert and other authors listed the following three agencies as the principle facilities that had conducted the theoretical research:

[edit] Gravity Research Foundation

Several articles contained expressions of gratitude for the support to the gravity control propulsion initiative by the Gravity Research Foundation.[18][19] Even though the Foundation was a humble, non-profit organization, its creator, Roger Babson, used his wealth and influence to mobilize industries; raise private and government funding; and motivate engineers and physicists to conduct research in gravity shielding and control.[20] According to his autobiography: "The purpose of the Foundation is to encourage others to work on gravity problems and aid others in obtaining rewards for their efforts."[21]

During Babson's lifetime, the Foundation conducted Gravity Day Conferences each summer; established a library on gravity; solicited essays that addressed (1.) various prospects for shielding gravity, (2.) the development and/or discovery of materials that could convert gravitational force into heat, or (3.) methods of manipulating gravity;[22] and enstalled monuments at various universities that cited its antigravity focus.

[edit] Aerospace Research Laboratories (ARL)

In September, 1956, the General Physics Laboratory of the Aeronautical Research Laboratories (ARL) at Wright-Patterson Air Force Base, Dayton, Ohio, commenced an intense program to coordinate research into gravitational and unified field theories with the hiring of Joshua N. Goldberg.[3] Creation by ARL of Goldberg's program may have been coincidental to the Talbert's disclosures of the initiative.[16] The precise rationale for creating the program and justifying its budgets and personnel may never be determined. Neither Goldberg nor the Air Force's Deputy for Scientific and Technical Information, Walter Blados, were able to locate the founding documents.[3] Roy Kerr, a former ARL scientist, stated the antigravity propulsion purpose of ARL was "rubbish" and that "The only real use that the USAF made of us was when some crackpot sent them a proposal for antigravity or for converting rotary motion inside a spaceship to a translational driving system."[23]

During the following sixteen years, its name was changed to the Aerospace Research Laboratories. The ARL scientists produced nineteen technical reports[3] and over seventy peer-reviewed journal articles.[24] The Air Force's Foreign Technical Division,[25] and other agencies,[26] investigated stories[27][28] about Soviet attempts to understand gravity. Such actions were consistent with the paranoia of the Cold War.

The funding for the military components of the initiative had been terminated by the Mansfield Amendment of 1973. Black project experts,[6] conspiracy theorists,[13] and whistleblowers[9][11] had suggested the gravity control propulsion initiative had achieved its goals and had been continued decades beyond 1973.

[edit] Research Institute for Advanced Study (RIAS)

The Research Institute for Advanced Study (RIAS) was conceived by George S. Trimble, the vice president for aviation and advanced propulsion systems, Glenn L. Martin Company, and was placed under the direct supervision of Welcome Bender. The first person Bender hired was Louis Witten internationally recognized authority on gravitation physics.[29] Talbert's article had announced Trimble's completion of contractual agreements with Pascual Jordan and Burkhard Heim for RIAS. Subsequent hires yielded a half dozen gravity researchers known as the field theory group. Sir Arthur C. Clarke and others stated RIAS' assemble of talent were very qualified for the task of discovering new principles that could be used to develop gravity control propulsion systems.[30]

The quest for propulsion through gravity control was vaguely implied in various publications. Works by Cook and Cleaver summarized statements in the RIAS brochures. Cook had equated the broad range of RIAS's mission statements with those of Skunk Works. In 1958, Mallan reported “the control of the force of gravity itself for propulsion” was one of the unorthodox goals initiated by Trimble for RIAS.[31]

RIAS was renamed the Research Institute for Advanced Studies during the sixties when the American-Marietta Company merged with Martin to become the Martin Marietta Company. The 1995 merger that yielded the Lockheed Martin Company modified its goals and not its name. Web searches on either spelling yielded numerous files.

[edit] Aerospace firms

Talbert's newspaper series and subsequent articles in technical magazines and journals listed the names of aerospace firms conducting gravity control propulsion research. The Gravity Research Group indicated those companies had constructed "rigs" to improve the performance of Thomas Townsend Brown's gravitators through attempts to develop materials with high dielectric constants (k).[1] Gravity Rand Limited provided a set of guidelines to help management conduct research and nurture creativity.[32] Articles about the initiative aerospace firms ceased after 1976. None of the companies featured in those publications had filed retractions. The following is a list of the aerospace firms that had been cited in the works published from 1955 through 1976:

  • Radio Corporation.[13]

[edit] Reported breakthroughs

None of the reported experimental breakthroughs published during the 1950s and 1960s have been recognized by the aerospace community.

[edit] Experimental

[edit] Brown's gravitator

Various reports indicated Brown's gravitators were the main experimental focus of the gravity control propulsion initiative.[1] According to G. Harry Stine and Intel, research on Brown's gravitators became classified immediately after demonstrations of 30% weight reductions.[35][36] Thomas Townsend Brown had obtained a British patent for high voltage, symmetric, parallel plate capacitors, that he called gravitators, in 1928.[37] Brown claimed they would produce a net thrust in the direction of the anode of the capacitor that varified slightly with the positions of the Moon.[38] The scientific community rejected such claims as products of pseudoscience and/or misinterpretations of ion wind effects. Repeatable results from the Trouton-Noble experiment have not supported such claims.

[edit] Martin's gravity-like impulses

In July 1960, Missiles and Rockets reported Martin N. Kaplan, Senior Research Engineer, Electronics Division, Ryan Aeronautical Company, San Diego, had conducted antigravitational experiments yielding the promise of impulses, accelerations, and decelerations one hundred times the pull of gravity.[33] Neither comments nor criticism of the report appeared in subsequent articles during the period of the gravity control propulsion initiative.

[edit] Theoretical

[edit] Forward's protational field

Robert L. Forward, Hughes Research Laboratories, Malibu, described the theoretical generation of dipole gravitational fields by accelerating a super-dense fluid through pipes wound around a torus.[39] Such techniques, though theoretically sound, have been far beyond the reach of technology.

[edit] Heim's principles of dynamic counterbary

Surveys conducted by engineers of physical principles as potential foundations for gravity control propulsion theories conferred high ratings for Burkhard Heim's work.[15][40] Comments by physicists about his initial and extended propulsion theories appeared during 2008 in a peer reviewed journal.[41] Heim's earliest paper was completed in 1956 as a progress report that was archived at the Gravity Research Foundation.[42] His theory was then published in a series of four papers during 1959 by a little known aerospace engineering journal.[43] According to Helmut Goeckel's preface to the first paper in the series, unbridled interest of unsavory firms had caused Heim to cease from further developments of his propulsion theory. He indicated various aerospace and ordnance companies had made several attempts to kidnap him. Heim devoted the remainder of his life to refining the unified field attributes of his theory.

[edit] Legacies

Many of the contributors to general relativity have been supported by and/or associated with the ARL, RIAS, and/or the Gravity Research Foundation. The decades preceding the 1955 revelation of the gravity control propulsion initiative were a low water mark for general relativity.[44][45] The following summarizes how the components of the initiative had stimulated the resurgence of general relativity:

[edit] Gravity Research Foundation

Even though some of the physicists who attended the Gravity Day Conferences quietly mocked the anti-gravity mission of the Foundation,[46] it provided significant contributions to mainstream physics.[47] The International Journal of Modern Physics D has featured selected papers from the Gravity Research Foundation essay competition. Many have been incorporated with the collections of the Niels Bohr Library. A few of the Foundation essay contest winners became Nobel laureates (e.g., Ilya Prigogine, Maurice Allais, George F. Smoot). Foundation essays have been among the resources graduate students check for new ideas.[20] Kaiser summarized the Foundation's influence in the following manner: "Despite the vast conceptual gulf separating Babson from the new generation of relativists, we are left with intriguing, and perhaps ironic associations: by organizing conferences, sponsoring the annual essay contests, and making money and enthusiasm widely available for people interested in gravity, the eccentric Gravity Research Foundation may claim at least some small amount of the credit for helping to stimulate the postwar resurgence of interest in gravitation and general relativity."[2]

Foundation trustee, Agnew Bahnson, contacted Dr. Bryce DeWitt with a proposal to fund the creation of a gravity research institute.[2][48] DeWitt had won the first prize for the 1953 essay contest. The proposed name was changed to the Institute for Field Physics and it was established in 1956 at the University of North Carolina at Chapel Hill under the direction of Bryce and his wife, Cécile DeWitt-Morette.[4]

The peer reviewed physics journal, Physica C, published a report by Eugene Podkletnov and Nieminen about gravity-like shielding.[49] Although their work had gained international attention, researchers were not able to replicate Podkletnov's initial conditions.[50][51] But, analyses by Giovanni Modanese[52] and Ning Wu[53] indicated various applications of quantum gravity theory could allow gravitational shielding phenomena. Those achievements have not been pursued by the scientific community.

[edit] Aerospace Research Laboratories (ARL)

The list of prominent contributors to the golden age of general relativity, contains the names of several scientists who had authored the nineteen ARL Technical Reports and/or seventy papers. The ARL sponsored papers were published in the Proceedings of the Royal Society of London, Physical Review, Journal of Mathematical Physics, Physical Review Letters, Physical Review D, Review of Modern Physics, General Relativity and Gravitation, International Journal of Theoretical Physics, and Nuovo Cimento B. Some of the ARL papers were written in collaboration with RIAS, the U.S. Army Signal Research and Development Laboratory at Fort Monmouth, New Jersey, and the Office of Naval Research. The ARL had provided significant enhancements to general relativity theory. For example, Roy Kerr's description of the behavior of space-time in the vicinity of a rotating mass was among those works.[54] Goldberg concluded: "However, it should be recognized that, in the United States, the Department of Defense played an essential role in building a strong scientific community without widespread encroachment on academic values."[3]

[edit] Research Institute for Advanced Studies (RIAS)

The growth of nonlinear differential equations during the fifties was stimulated by RIAS. One of the leading groups in dynamical systems and control theory, the Lefschez Center for Dynamical Systems,[5] was a spinoff from RIAS. After the launch of Sputnik, world-class mathematician Solomon Lefschetz came out of retirement to join RIAS in 1958 and formed the world's largest group of mathematicians devoted to research in nonlinear differential equations.[55] The RIAS mathematics group stimulated the growth of nonlinear differential equations through conferences and publications. It left RIAS in 1964 to form the Lefschez Center for Dynamical Systems at Brown University, Providence, Rhode Island.

[edit] UFO and conspiracy theories

On May 9, 2001, Mark McCandlish testified on the televised news conference held by the Disclosure Project, at the National Press Club, Washington, D.C. He stated gravity control propulsion research had started in the fifties and had successfully reverse engineered the vehicle retrieved from the Roswell crash site to build three Alien Reproduction Vehicles by 1981.[6] McCandlish described their propulsion systems in terms of Thomas Townsend Brown's gravitators and provided a line drawing of its interior. The diagram closely resembled the drawing provided earlier in Milton William Cooper's book. Another Disclosure Project whistleblowers, Lt. Col Philip J. Corso, stated in his book the craft retrieved from the second crash site at Roswell, New Mexico, had a propulsion system resembling Thomas Townsend Brown's gravitators.[56] And, Corso's book featured several gravity control propulsion statements made by Professor Hermann Oberth.

Soon after America had won the Cold War, a small group of scientists and engineers openly expressed their desire to use technologies developed by black projects for civil applications.[57] Dr. Steven Greer formed the Disclosure Project in 1995 to help those and other research whistleblowers share their information with and to petition Congress. By 2001, it had provided reports to two Congressional hearings and had acquired over 400 members from branches of the military and aerospace industry.

During the early 1960s, Keyhoe published excerpts from a letter by Hermann Oberth that presented explanations for the flight characteristics of UFO's in terms of gravity control propulsion.[13] Keyhoe also stated forty-six unclassified G-projects had been confirmed by a 1965 research report from the Smithsonian Science Information Exchange, Smithsonian Institution.

During his press conferences on February 2, 1955 in Bogotá, Colombia, and February 10, 1955 in Grand Rapids, Michigan, the famous aviation pioneer, William Lear, stated one of his reasons for believing in flying saucers was the existence of American research efforts into antigravity.[58] Talbert's series of newspaper articles about the gravity control propulsion initiative were published during the Thanksgiving week of that year.
