“…Nonetheless there has been ongoing interest in whether the speed of light really is invariant (Albrecht & Magueijo, 1999;Barrow & Magueijo, 1999;Bassett, Liberati, Molina-Paris, & Visser, 2000;Clayton & Moffat, 2003;Magueijo, 2001Magueijo, , 2003Magueijo, , 2008Moffat, 2005;Singha & Debnath, 2007;Sisterna, 2011;Szydlowski & Krawiec, 2003;Unzicker, 2009). The primary purpose of these endeavours has been to explore for new physics at deeper levels, with a particular interest in quantum-gravity.…”

Problem-The theory of Relativity is premised on the constancy of the speed of light (c) in-vacuo. While no empirical evidence convincingly shows the speed to be variable, nonetheless from a theoretical perspective the invariance is an assumption. Need-It is possible that the evidence could be explained by a different theory. Approach-A non-local hidden-variable (NLHV) solution, the Cordus particule theory, is applied to identify the causes of variability in the fabric density, and then show how this affects the speed of light. Findings-Under these assumptions the speed of light is variable (VSL), being inversely proportional to fabric density. This is because the discrete fields of the photon interact dynamically with the fabric and therefore consume frequency cycles of the photon. The fabric arises from aggregation of fields from particles, which in turn depends on the proximity and spatial distribution of matter. Results disfavour the universal applicability of the cosmological principle of homogeneity and isotropy of the universe. Originality-The work proposes causal mechanisms for VSL, which have otherwise been challenging to ascertain. Uniquely, this theory identifies fabric density as the dependent variable. In contrast, other VSL models propose that c varies with time or some geometric-like scale, but struggle to provide plausible reasons for that dependency. This theory also offers a conceptually simply way to reconcile the refraction of light in both gravitational situations and optical materials.

“…The ideas of Sciama, originally published in 1953, seem to be more recognized although his approach and contributions to cosmology were soon abandoned [15]. He focused mainly on the question of the correct interpretation of the physical foundations of GTR [16] and the fundamental role played by Mach's principle on it, having proposed a quantitative implementation of this principle in which the value of G is not anymore an arbitrary constant and somewhat mysteriously connected to the whole universe.…”

In the present work we propose a generalization of Newton's gravitational theory from the original works of Heaviside and Sciama, that takes into account both approaches, and accomplishes the same result in a simpler way than the standard cosmological approach. The established formulation describes the local gravitational field related to the observables and effectively implements the Mach's principle in a quantitative form that retakes Dirac's large number hypothesis. As a consequence of the equivalence principle and the application of this formulation to the observable universe, we obtain, as an immediate result, a value of Omega = 2. We construct a dynamic model for a galaxy without dark matter, which fits well with recent observational data, in terms of a variable effective inertial mass that reflects the present dynamic state of the universe and that replicates from first principles, the phenomenology proposed in MOND. The remarkable aspect of these results is the connection of the effect dubbed dark matter with the dark energy field, which makes it possible for us to interpret it as longitudinal gravitational waves.Comment: 18 pages, 4 figures.

“…One such problem that has been discussed herein is the anomalous angular sizes concerning cosmic redshifted entities, primarily galaxies and quasars (Lopez -Cordera, 2010;Unzicker;2010). Many astronomers have noted that the observation angles of galaxies are generally inversely proportional to their observed redshifts based upon Hubble calculated distances.…”

“…Another proposal was made by Fred Hoyle, Jayant Narlikar (Das, 1998) whereby the diameter of matter accordingly decreases over time by electrons becoming closer to the nucleus of atoms. One of the latter proposals was by Robert Dicke (Wikipedia, Robert H. _ Dicke, 2011) directly related to the alternative model proposed herein, whereby in 1957 he proposed that "the cosmological redshift is described by a shortening of measuring rods rather than an expansion of space" (Dicke et al, 2008;Unzicker, 2007) which is the same explanation for the subject cosmological model.…”

The purpose of this research and study was to help derive and test new theoretical equations to accurately determine cosmological distances and luminosities for all cosmological entities without the need for the dark energy hypothesis. These derived equations were based upon an alternative cosmological model and a study of type 1a supernovae observation data. This paper presents the results of this research and study and the resultant new equations.A new distance equation is presented in this paper for peer consideration for the first time. It is proposed as an eventual replacement for the Hubble distance formula concerning calculated cosmic distances based upon redshifts. A new "brightness equation" is also offered herein. Its calculations are required to accompany the calculations of the distance equation to determine brightnesses and is proposed as an addendum to the inverse square law of light concerning luminosity calculations for cosmic-redshifted distances. In the subject supernova study these alternative equations are used to show their application and proposed validity concerning calculated distances and observed brightnesses of type 1a supernovae.The proposed alternative distance equation is very different from the Hubble distance formula since it is directly linear and was derived from an entirely different non-expanding-universe cosmology, tested and refined based upon a study of type 1a supernova data involving the subject applied physics research. Explanations of the alternative cosmological model are presented here for the consideration of their merits. Hopefully these proposed equations will be tested by many others concerning all types of cosmological-distance observations of redshifts requiring distance and brightness-determination calculations, eventually resulting in the serious consideration of the subject cosmological model for reasons discussed in this paper.
