Kaluza-Klein Gravity, Concentrating on the General Rel- Ativity, Rather Than Particle Physics Side of the Subject
Kaluza-Klein Gravity J. M. Overduin Department of Physics and Astronomy, University of Victoria, P.O. Box 3055, Victoria, British Columbia, Canada, V8W 3P6 and P. S. Wesson Department of Physics, University of Waterloo, Ontario, Canada N2L 3G1 and Gravity Probe-B, Hansen Physics Laboratories, Stanford University, Stanford, California, U.S.A. 94305 Abstract We review higher-dimensional unified theories from the general relativity, rather than the particle physics side. Three distinct approaches to the subject are identi- fied and contrasted: compactified, projective and noncompactified. We discuss the cosmological and astrophysical implications of extra dimensions, and conclude that none of the three approaches can be ruled out on observational grounds at the present time. arXiv:gr-qc/9805018v1 7 May 1998 Preprint submitted to Elsevier Preprint 3 February 2008 1 Introduction Kaluza’s [1] achievement was to show that five-dimensional general relativity contains both Einstein’s four-dimensional theory of gravity and Maxwell’s the- ory of electromagnetism. He however imposed a somewhat artificial restriction (the cylinder condition) on the coordinates, essentially barring the fifth one a priori from making a direct appearance in the laws of physics. Klein’s [2] con- tribution was to make this restriction less artificial by suggesting a plausible physical basis for it in compactification of the fifth dimension. This idea was enthusiastically received by unified-field theorists, and when the time came to include the strong and weak forces by extending Kaluza’s mechanism to higher dimensions, it was assumed that these too would be compact. This line of thinking has led through eleven-dimensional supergravity theories in the 1980s to the current favorite contenders for a possible “theory of everything,” ten-dimensional superstrings. -

Misner/Wheeler Correct About Einstein's Unified Field Theory Being Successful Author
Title – Misner/Wheeler correct about Einstein's Unified Field Theory being successful Author – Rodney Bartlett Abstract – In 1957, Charles Misner and John Wheeler, in the “Annals of Physics”, claimed Albert Einstein’s latest equations demonstrated the unified field theory. It has been argued that the gravitational fields, if known everywhere but only for a limited time, do not contain enough information about their electromagnetism to allow the future to be determined, so Einstein's unified theory fails. Physicists also argue that a unified "theory of everything" must now include not just gravity and electromagnetism, but also the weak and strong nuclear forces plus dark matter and dark energy. This article claims Misner and Wheeler were correct, and addresses all modern objections. Content - It is my belief that Charles Misner and John Wheeler were correct in 1957 when they said Einstein was successful in proving his Unified Field Theory. Einstein successfully proved the Unified Field Theory, combining gravitational and electromagnetic equations. Despite what modern science mistakenly thinks, this means everything (electromagnetism, time, space, matter, dark matter, dark energy and the nuclear forces within atoms) has no separate existence from gravitation. In the 19th century, Scottish mathematician and physicist James Clerk Maxwell unified electricity and magnetism into electromagnetism. Albert Einstein's equations say that in a universe possessing only gravitation and electromagnetism, the gravitational fields carry enough information about electromagnetism to allow the equations of Maxwell to be restated in terms of these gravitational fields. This was discovered by the mathematical physicist George Yuri Rainich (1886 -1968). England’s Professor Penrose has argued that the gravitational fields, if known everywhere but only for a limited time, do not contain enough information about their electromagnetism to allow the future to be determined, so Einstein's unified theory fails. -
Plasma Modes in Surrounding Media of Black Holes and Vacuum Structure - Quantum Processes with Considerations of Spacetime Torque and Coriolis Forces
COLLECTIVE COHERENT OSCILLATION PLASMA MODES IN SURROUNDING MEDIA OF BLACK HOLES AND VACUUM STRUCTURE - QUANTUM PROCESSES WITH CONSIDERATIONS OF SPACETIME TORQUE AND CORIOLIS FORCES N. Haramein¶ and E.A. Rauscher§ ¶The Resonance Project Foundation, [email protected] §Tecnic Research Laboratory, 3500 S. Tomahawk Rd., Bldg. 188, Apache Junction, AZ 85219 USA Abstract. The main forces driving black holes, neutron stars, pulsars, quasars, and supernovae dynamics have certain commonality to the mechanisms of less tumultuous systems such as galaxies, stellar and planetary dynamics. They involve gravity, electromagnetic, and single and collective particle processes. We examine the collective coherent structures of plasma and their interactions with the vacuum. In this paper we present a balance equation and, in particular, the balance between extremely collapsing gravitational systems and their surrounding energetic plasma media. Of particular interest is the dynamics of the plasma media, the structure of the vacuum, and the coupling of electromagnetic and gravitational forces with the inclusion of torque and Coriolis phenomena as described by the Haramein-Rauscher solution to Einstein’s field equations. The exotic nature of complex black holes involves not only the black hole itself but the surrounding plasma media. The main forces involved are intense gravitational collapsing forces, powerful electromagnetic fields, charge, and spin angular momentum. We find soliton or magneto-acoustic plasma solutions to the relativistic Vlasov equations solved in the vicinity of black hole ergospheres. Collective phonon or plasmon states of plasma fields are given. We utilize the Hamiltonian formalism to describe the collective states of matter and the dynamic processes within plasma allowing us to deduce a possible polarized vacuum structure and a unified physics. -
Einstein and the Kaluza-Klein Particle
ITFA-99-28 Einstein and the Kaluza-Klein particle Jeroen van Dongen1 Institute for Theoretical Physics, University of Amsterdam Valckeniersstraat 65 1018 XE Amsterdam and Joseph Henry Laboratories, Princeton University Princeton NJ 08544 Abstract In his search for a unified field theory that could undercut quantum mechanics, Einstein considered five dimensional classical Kaluza-Klein theory. He studied this theory most intensively during the years 1938-1943. One of his primary objectives was finding a non-singular particle solution. In the full theory this search got frustrated and in the x5-independent theory Einstein, together with Pauli, argued it would be impossible to find these structures. Keywords: Einstein; Unified Field Theory; Kaluza-Klein Theory; Quantization; Soli- tons 1 Introduction After having formulated general relativity Albert Einstein did not immediately focus on the unification of electromagnetism and gravity in a classical field theory - the issue that would characterize much of his later work. It was still an open question to him whether arXiv:gr-qc/0009087v1 26 Sep 2000 relativity and electrodynamics together would cast light on the problem of the structure of matter [18]. Rather, in a 1916 paper on gravitational waves he anticipated a different development: since the electron in its atomic orbit would radiate gravitationally, something that cannot “occur in reality”, he expected quantum theory would have to change not only the ”Maxwellian electrodynamics, but also the new theory of gravitation” [19]2. Einstein’s position, however, gradually changed. From about 1919 onwards, he took a strong interest in the unification programme3. In later years, after about 1926, he hoped that he would find a particular classical unified field theory that could undercut quantum theory. -
Fundamental Geometrodynamic Justification of Gravitomagnetism
Issue 2 (October) PROGRESS IN PHYSICS Volume 16 (2020) Fundamental Geometrodynamic Justification of Gravitomagnetism (I) G. G. Nyambuya National University of Science and Technology, Faculty of Applied Sciences – Department of Applied Physics, Fundamental Theoretical and Astrophysics Group, P.O. Box 939, Ascot, Bulawayo, Republic of Zimbabwe. E-mail: [email protected] At a most fundamental level, gravitomagnetism is generally assumed to emerge from the General Theory of Relativity (GTR) as a first order approximation and not as an exact physical phenomenon. This is despite the fact that one can justify its existence from the Law of Conservation of Mass-Energy-Momentum in much the same manner one can justify Maxwell’s Theory of Electrodynamics. The major reason for this is that in the widely accepted GTR, Einstein cast gravitation as a geometric phenomenon to be understood from the vantage point of the dynamics of the metric of spacetime. In the literature, nowhere has it been demonstrated that one can harness the Maxwell Equa- tions applicable to the case of gravitation – i.e. equations that describe the gravitational phenomenon as having a magnetic-like component just as happens in Maxwellian Elec- trodynamics. Herein, we show that – under certain acceptable conditions where Weyl’s conformal scalar [1] is assumed to be a new kind of pseudo-scalar and the metric of spacetime is decomposed as gµν = AµAν so that it is a direct product of the components of a four-vector Aµ – gravitomagnetism can be given an exact description from within Weyl’s beautiful but supposedly failed geometry. My work always tried to unite the Truth with the Beautiful, consistent mathematical framework that has a direct corre- but when I had to choose one or the other, I usually chose the spondence with physical and natural reality as we know it. -
Gravitation in Unified Scalar Field Theory

Chernitskii 1,2,† 1 Department of Mathematics, St. Petersburg State Chemical Pharmaceutical University, 197022 St. Petersburg, Russia; [email protected] or [email protected] 2 A. Friedmann Laboratory for Theoretical Physics, The Herzen University, 191186 St. Petersburg, Russia † Current address: Prof. Popov str. 14, 197022 St. Petersburg, Russia. Abstract: The scalar field of space-time film is considered as unified fundamental field. The field model under consideration is the space-time generalization of the model for a two-dimensional thin film. The force and metrical interactions between solitons are considered. These interactions correspond to the electromagnetic and gravitational interactions respectively. The metrical interaction and its correspondence to the gravitational one are considered in detail. The practical applications of this approach are briefly discussed. Keywords: unified field; space-time film; soliton-particle; gravitation; dark matter; gravitational screening 1. Introduction 1.1. Unified Fundamental Field The concept of unified fundamental field has existed for a sufficiently long time. According to this concept, matter in all its multiformity can be considered as a solution of some nonlinear field model. In particular, all elementary particles must be represented by soliton solutions of the model. In this case their interactions are the consequence of the field model nonlinearity. The nonlinearity violates the superposition property for solutions of the appropriate Citation: Chernitskii, A.A. linearized model. According to this property the sum of solutions is also solution. The Gravitation in Unified Scalar Field violation of the superposition property is interpreted as the interaction of particles. -

Keywords: Gauge Theory, Electroweak Interactions, Metric, Gravitation, con- nectivity. 1 Introduction Attempts to build a unified theory of all interactions, a unified field theory, began before Einstein created the General theory of relativity. The first of the interaction theories was the theory of electromagnetism, created by Maxwell in 1863. In 1915, Einstein formulated the General theory of relativity describing the gravitational field. Just as Maxwell was able to create a General description of electrical and magnetic phenom- ena, the idea of building a unified theory of fundamental interactions arose. This prob- lem was posed by D. Gilbert. Einstein proposed a large number of options for unifica- tion gravity and the electromagnetic field [1-7]. -
The Computational Unified Field Theory: What Is "Time"?

By Jehonathan Bentwich, Ph.D. Introduction: A Material-Causal Conception of Time- According to the current 'Material-Causal' Paradigm underlying both Relativity Theory and Quantum Mechanics, "time" is an "observer- dependent", "uni-directional", "material-causal" entity: Its "flow" is "unidirectional", i.e., it can only move from the "present" to the "past" but not from the "future" to the "past"… This is because, according to Relativity Theory, nothing can travel faster than the speed of light so no observer can "catch" any light signal emanating from any "past" even". According to Quantum Mechanics, following the "collapse" of the subatomic target's "probability wavefunction" as "caused" by its direct physical interaction with a corresponding subatomic "probe" element – e.g., into a single (space-energy, temporal-mass) value, it is not possible to "un-collapse" this singular ("collapsed") target value back into the (preceding) multifarious "probability wave function" state… Hence, "time-reversal" is not possible according to both Relativity Theory and Quantum Mechanics, which are underlie by the Old "Material-Causal" Paradigm of 20th century Theoretical Physics; GJSFR-A Classification: FOR Code: 010399 TheComputationalUnifiedFieldTheoryWhatisTime Strictly as per the compliance and regulations of: © 2018.

THE UNIFYING OF THE FORCES OF NATURE Bertrand Wong, Eurotech, S’pore Email: [email protected] Abstract This paper takes a look at the formulating of the unified field theory and the theory of everything. It shows how a unified field theory and theory of everything may be obtained. Keywords: forces of nature, dimensions, supersymmetry, simulation, unification PACS: 04.20.Cv, 11.30.Pb & 89.20.Ff Introduction The paper proposes a practical way to arrive at a unified field theory and theory of everything, based on the author’s experiences with computer simulation. Having only a beautiful theory and beautiful equations to model nature are insufficient for affirming the characteristic of the universe. The affirmation has to be ultimately carried out by physical experiment. However, in lieu of physical experimentation, computer simulation is proposed, simulation with powerful software having been effectively utilized in areas such as aeronautical, electronic, mechanical and marine designs, wherein it now becomes unnecessary to produce costly prototypes. A few possible ways of unification are also presented. 1 Forces Of Nature And Unification Our views of nature may be modified in the future. For instance, superstring theories, which had been neglected in the past, are now the “in” thing, being regarded by many scientists as beautiful, or, elegant, and a possible theory of everything. Einstein had attempted to unify the four forces of nature, i.e., gravity, weak nuclear force, strong nuclear force and electromagnetism, but had failed. As in the past, he was unable to derive the electromagnetic field equations, even for the weak- field approximation. -
The Coset Space of the Unified Field Theory
The coset space of the unified field theory Simon Davis Abstract. The coset space of the unified field theory is postulated, based on the automorphism group of the spinor space, which has been deter- mined to be a direct sum as a result of the unitarity of the CKM matrix. Reduction sequences are considered, particularly in connection with vector bosons of the strong interactions and the six-dimensional theory yielding the Weinberg-Salam model upon integration over S2. The embedding of the manifold in a twelve-dimensional unified theory is established, and a solution to the field equations with a given form of the Ricci tensor G2×SU(2)×U(1) is found. A coset space space SU(3)×U(1)0×U(1)00 satisfying the holonomy condition for the Ricci tensor derived from the spinor equations is either nonsupersymmetric or admits a maximal N = 1 supersymmetry. The greater weighting of a compactification of the reduced ten-dimensional theory over G2=SU(3) is verified, confirming the relevance of the elemen- tary particle interactions. M.S.C. 2010: 20C36, 20F29, 81T13, 81T30. Key words: spinor space; automorphism group; embedding; twelve-dimensional theory. 1 Introduction The unification of the elementary particle interactions in higher dimensions requires a compact space which will yield the standard model upon reduction to four dimen- sions. The compactification of space-time over a coset manifold produces the gauge group SU(3) × SU(2) × U(1) with known quark and lepton numbers if the inter- klm SU(3)×SU(2)×U(1) nal symmetry space L = SU(2)×U(1)0 occurs as a limit of solutions to the klm SU(3)×SU(2)×U(1) 11-dimensional supergravity equations, M = SU(2)×U(1)0×U(1)00 [10][69], when the embedding parameters for the U(1)0 and U(1)00 factors are chosen to coincide at cer- tain values [70].
