Influenced by Einstein’s two dictums on incorporation of maximum of empirical facts with least of hypothesis, and on long-continued experimental verifications for perfecting his theory of relativity, the authors reviewed with special emphasis the “ad-hoc” or
alternative methods or approaches that mathematical astronomers (working on celestial mechanics) and physicists continued to adopt in their respective fields while presenting their relativity-related experimental data or results, which makeup the “century-long experience of relativity-related
experiments on physics, astronomy, and celestial mechanics” (CEREPAC). Faced with the limitations of the concept of “constancy of c” in different branches of physics, Professor Byer [Ke-Xun Sun et al, Astro 2010 White Paper for Technology Development, Stanford University],
the developer of miniaturized space-qualified laser is leading the space time asymmetry research (STAR) mission, which aims to greatly advance the field of fundamental physics, and has two important Baseline Objectives among those stated in the National Aeronautics and Space Administration
Science Plan (2007‐2016): to test the validity of Einstein's General-Relativity-Theory (GRT) and to detect the “sought-after departure” Δc. A study of the annals of GRT, and Prof. Will's [Living Rev. Relativ. 17, 4 (2014)] observation from the annals of GRT reveal
that GRT grew in isolation from celestial-mechanics and mathematical-astronomy, and also to some extent from mainstream physics during 1920‐1960. Subsequently, the mathematical-astronomers in Jet Propulsion Laboratory, applied the numerical simulation methods utilizing the high precision
space-age ranging data to “n-body problem in Gravitation,” and developed an evolved or a more successful version, namely, GRT-astronomers model, while the older GRT-conventional model cannot perform numerical simulation of lunar and planetary orbits. To eliminate the principal
downside of GRT-astronomers model, the authors incorporated relativistic-time for integration instead of nonrelativistic time, and avoided incorporating any hypothesis related to constancy of c, and the outcome was GRT-astronomers (modified) model. Subsequently, utilizing available
clues from CEREPAC, further efforts by the authors led to the formulation of the remodeled relativity theory (RRT) by retaining and incorporating only experimentally proven principles. RRT determines the variable local or coordinate speed cr
, which really is the local limiting
speed in nature. RRT also enables the elimination of all sorts of ad-hoc or alternative methods that got revealed from a review of CEREPAC, and helps to eliminate the problems and anomalies, associated with the century-long applications of GRT in astronomy, Celestial mechanics, and
physics. Additionally, RRT has eliminated the black-hole-paradoxes of GRT and has shown that the higher redshifts of the compact celestial bodies (viz., in NGC 7603) provide observational evidences for RRT. As observational evidences provided first-level proofs for RRT, a low-cost “Direct”
space experiment has been proposed in 2009 for verifying the RRT-predicted value of cr
. Thus, evidently RRT has become an evolved version of GRT, and it made possible the first-time computation of the lower limit for cr
at 299 792 457.79 m/s, which
is the minimum magnitude of c in nature, c
0, as measurable at infinite distance from all gravitating bodies. Also, RRT has generated the equation for Δc of STAR mission and produced its values (that cannot be done using the first two models) along a vast tract
of space for verification during the STAR and similar missions.
