Execution and other details for the space experiment proposed for theories of relativistic gravitation

More than half a century before the advent of space age, overcoming the constraints of contemporary physics, Einstein formulated his Special Relativity Theory (SRT) by abandoning the prevalent ether theory, by replacing Newton's three absolutes (mass, time, and space) by a single absolute, the speed of light, c, and by introducing the radical concept of relativistic time; he laid particular emphasis on the importance of continued experimental verification of the theoretical principles of the theory of relativity. After almost a decade of successful results from SRT experiments, Einstein submitted his paper on General Relativity, and made a categorical statement (on the general relativistic nature of c) that the special relativity postulate of constancy of c is not valid under the influence of gravitational fields as the curvature of light rays can only take place when c varies with position. Influenced by Einstein's two dictums on incorporation of maximum of empirical facts, and on long-continued experimental verifications, for perfecting the relativity theory, the authors formulated the Remodeled Relativity Theory (RRT) based on the study of the century-long experience of relativity related experiments on Physics, Celestial mechanics, and Astronomy, and by retaining and incorporating only experimentally proven principles. An Einsteinian concept that a beam of light will bend in a gravitational field “exactly” as a material body would, if thrown horizontally with a velocity equal to c, was adopted in this remodeled theory; this leads to a rigorously determined (from numerical simulation) magnitude of c, which varies with position, increasing gradually at locations closer to the sun or massive celestial bodies, and which also conforms to the experimentally proven principle that higher energy level is the underlying cause for a stronger relativistic effect. At locations close to the compact emission line objects 2 and 3 in Seyfert Galaxy NGC 7603, the RRT-estimated value of c had already been reported in a previously published paper, to be, respectively, 1.243 and 1.391 times the value of the terrestrial c; the higher redshifts of these compact objects provide observational evidences for RRT. This shows that applying the value of terrestrial cas the limiting value of c (in disagreement with Einstein's categorical statement mentioned above) beyond the “sphere of influence” of Earth's gravitational field is leading and will lead to discrepancies or anomalies. For verification of the RRT-estimated value of c (at locations closer to the sun and beyond the “spheres of gravitational influence” of the earth and other planets), from a “direct” experiment, and for fulfilling a few other important objectives, the proposed low-cost space experiment needs to be conducted by sending a miniaturized space qualified 633 nm Iodine Stabilized Helium-Neon Laser device in a spacecraft, during any of the future Space missions to Venus, Mercury, or the sun. It is expected that NASA, ESA, ASI, ISRO, or any other Space research organization would now plan and conduct the proposed low-cost experiment, as it is possible now for even a small country by sending one microsatellite, using any other lending country's launching or launch-sharing facility.
