“…Of course, such a drift of atomic spectra should show up in various physical domains, noteworthy as a consequence of a corresponding drift of atomic clocks. In particular, an apparent increase of lengths measured through the time it takes for electromagnetic waves to go from a place to another should be observed [60].…”

Within the frame of the Λ cold dark matter paradigm, a dark energy component of unknown origin is expected to represent nearly 70% of the energy of the Universe. Herein, a non-standard form of the Hubble law is advocated, with the aim of providing safe grounds on which alternative cosmologies could be developed. Noteworthy, it yields an age-redshift relationship which is consistent with available data. Together with a straightforward analysis of gamma-ray burst counts, it further suggests that the observable Universe has been euclidean and static over the last 12 Gyr. Although a non-standard distance-duality relation is then required for interpreting luminosity distances, the magnitude-redshift relationship obtained is compatible with type Ia supernovae data.

“…Y.H. Sanejouand [18,19] expressed: Some empirical evidences in favor of the hypothesis that the speed of light decreases by a few centimeters per second each year are examined. Lunar laser ranging data are found to be consistent with this hypothesis, which also provides a straight forward explanation for the so-called Pioneer anomaly, that is, a time-dependent blue-shift observed when analyzing radio tracking data from distant spacecrafts, as well as an alternative explanation for both the apparent time-dilation of remote events and the apparent acceleration of the Universe.…”

A single field emerged at the origin of the universe, already containing within itself the blueprint of the physical universe. The primordial single field triggered the onset of the universe. Most physicists believe that a single super-force dominated the first instants of creation. Scientists have arrived at a simple but decisive conclusion that consciousness is very much a part of the universe, like other objects. Our consciousness model involving thought-carrying particle (TCP), thought retaining particle (TRP) and thought force (T F

“…Such a variation of the speed of light can account for the apparent acceleration of the expansion of the universe [71], without requiring the introduction of a cosmological constant. Note that the proposed theory shares similarities with Variable Speed of Light (VSL) theories [72], and therefore, it can also provide insight into other cosmological problems, such as the horizon, flatness, homogeneity and isotropy problems [73].…”

We present a theory of gravity based on Einstein's general relativity that is motivated by the paradoxes associated with time in relativistic rotating frames and certain exact solutions of Einstein's equations. We show that we can resolve these paradoxes with a single postulate, namely, the preservation of the local properties of time. This postulate forces the introduction of four additional degrees of freedom into the space-time structure whose transformation properties are defined to preserve the local properties of time under arbitrary four-dimensional coordinate transformations. We identify these additional degrees of freedom with the electromagnetic potentials, which thereby acquire a space-time interpretation. The resulting theory is similar to the traditional Einstein-Maxwell theory, differing primarily in the emergence of a coupling between the gravitational and electromagnetic fields. We show that the proposed reformulation of general relativity provides a rich framework for addressing a number of outstanding problems in contemporary gravitational physics.
