For the propagation of light in the presence of a gravitational field we use the equation: 1 Behram N Kursunoglu, Physical Review D Volume 14, Number 6, 15 September 1976 Quantum Gravity Generalized Theoryof Gravitation, andSuperstring Theory- Based Unification Edited by Kursunoglu et al Kluwer Academic / Plenum Publishers, New York 2000 3 (1) gµv dxµ dxV =0, where gµv is the metric of space-time representing... electromagnetism and more precisely, these cosmic phenomena provide, beyond any shadow of doubt, dramatic demonstration for the “Unified theory of electromagnetism and gravitation” In the general relativistic theory of gravitation electromagnetic energy and momentum do act as a source of gravity but in the unified theory gravity itself can act as a source of electromagnetism In fact the unified theory does...DEDICATION The trustees of the Global Foundation and members of the 28th Orbis Scientiae 1999, dedicate this conference to Dr Joseph Lannutti of Florida State University The late Professor Lannutti was a loyal and active member of this series of conferences on the frontiers of physics since 1964 He also served as a member of Global Foundation's Advisory Board Professor Lannutti was instrumental... fact that his version of the non-symmetric generalization of the general theory of relativity did not include the metric bµv The calculation of a variable speed of light has been performed1 for which a special case, irrespective of polarization and frequency, is given by V 2= 1 + W – ^2 sin2q + cos2q, 1 (1 + – W +I)2 2 (5) where q represents one of the angles to determine direction of the wave normal... ENERGY DEPENDENCE OF THE SPEED OF LIGHT EMERGING FROM COSMIC REGIONS Arnold Perlmutter Department of Physics University of Miami Coral Gables, FL 33124 Observations of very high energy g-rays from cosmological sources have increased in frequency and refinement Among the numerous examples of the emissions by Gamma Ray Bursters (GRB), several have led to estimates of the variation of the speed of the photons... interesting analysis(5) of the time delay of the signal of multi-TeV g-rays They use the result that various approaches to quantum gravity lead to a description of first order effects of a time dispersion(5), given by E – D t = x—— L (1) EQG c where Dt is the time delay relative to the standard energy-independent speed of light, c; x is a model-dependent factor of order 1; E is the energy of the observed radiation;... since the process of monopole condensation does not leave any room for the existence of free monopoles The flatness of the Universe in the unified field theory is a consequence of, as a result of the expansion of the universe, increasing size of r0 In this theory there exists no free monopoles all of them as a result of monopole condensation have been confined to create elementary particles Monopole .
