Unification of gravity and electromagnetism ??

[zbigniew.modrzejewski]

In order to unify the gravitational and electromagnetic fields, Einstein, et al., applied various geometrical structures and theoretical schemes, for example, the gauge invariance geometry, the five-dimensional space-time, the projective theory, the affine field and the bivector fields, etc. The non-symmetric field is the logically simplest relativistic field theory which is at all possible. Hlavaty made the summary and development. Johnson expounded systematically his viewpoints. Gaffney and Moffat, Boal obtained some conclusions and solutions. The unified field theories of more than four-dimensions were summarized. Madore proposed a modification of the traditional formulation of Kaluza-Klein theory in which the internal structure is described by a noncommutative geometry based on a semisimple algebra. The classical theory of Yang-Mills fields and of Dirac fermions is developed in the resulting geometry. The generalized connection is written down which should describe the unification of the Yang-Mills fields with gravity. Moreover, the unification is connected with the string model and the grand unification theory, and the supersymmetry and supergravity, etc. But, because the unified field theory is a very complex and difficult question, further approach should be made still. Recently, the unification of quantum field theory and general relativity as a fundamental goal of modern physics is discussed :

Principles of Maxwell, Lorentz, Milne, Dirac and Feynman are combined to unify gravity with electromagnetism. Special-relativistic settled reality (SR) evolves, as universe age increases, via cosmological Feynman paths. Although SR is ‘classical’, its evolution is ‘quantum mechanical’. A unitary Hilbert-space Lorentz-group representation--a lightlike-fiber-bundle— allows definition of divergenceless Lorentz-tensor self-adjoint retarded-potential operators. Feynman-path action (real but not SR) is invariant under a 7-parameter group that augments 6- parameter SL(2,c) by a 1-parameter compact (Kaluza-Klein) group generated by discrete electric charge. Sublightlike charged-particulate matter (a component of ‘objective reality’) reflects ‘zitterbewegung’—fluctuation of a lightlike-velocity direction specified by 2 angles of a 3-sphere fiber. The third fiber angle is Dirac conjugate to a discrete-spectrum electric-charge operator, whose commutation with all potential operators renders discrete the spatially-localized temporally-stable charged-particle component of SR :

And?

 

And, I am waiting for you to tell me that the unification of gravity and electromagnetism

is impossible, because such unification could be a physical basis

for the existence of ANTIGRAVITY —

Moderator Note

 

Nah - you do not get to circumvent previous moderator instructions not to open another thread on anti-gravity by quote mining a once-cited, obscure, and poorly-written paper from Arxiv nor by cherry picking a restricted access paper from 1983.

 

Thread locked - you already have too many threads on your pet topic.

 

Please try to post something of your own creation with the germ of a discussion rather that long cut'n'paste jobs
