Some Considerations on Physical Constants G and α in Light of the Concept of the Net Charged Universe (NCU) [1,2]

As described previously, the concept of a “Net Charged Universe” (NCU) assumes that the expansion of the universe is driven by a slight excess of positive charge in the universe’s matter. This excess charge comes into being by means of quantum fluctuations at the universe’s horizon. Excess protons experience electrostatic acceleration and therefore gain high relativistic mass, which is the source of the creation of neutral matter at the universe’s horizon. The present article investigates some consequences of that steady creation of space and matter in NCU history. The most important consequences are the following:  The gravitational constant G and the fine structure constant α are not constant but proportional to the historically decreasing mass density of the universe.  The commonality between G and α in terms of this proportionality seems to indicate a deep interdependency between both variables and between their related phenomena, i.e. the gravitational and electromagnetic properties of matter.  The historically decreasing value of G might be the real cause of anomalies of stars’ circling in galaxies, which led to the assumption of “Dark Matter” (DM) by current cosmology.  Because of a possibly holographic emergence of gravitation, newly created matter might immediately show its “gravitational presence” throughout the whole universe. In contrast to that, the “electromagnetic presence” of new matter propagates through space with the speed of light and cannot be immediately experienced in the inner universe. The value of α that varies with time and space can possibly be regarded as a measure for the fraction of all matter that is electromagnetically present at a certain place – e.g. our galaxy.  Calculations on the electromagnetic and the gravitational acceleration of matter in the NCU yield identical mathematical expressions although they were derived here in fully independent ways.  Finally, those expressions do not contain any “constants” like G, α, particle masses, elementary charge etc. – except the speed of light. The electromagnetic and the gravitational acceleration of matter are both controlled solely by geometrical variables, i.e. variable radii. These radii and the equations containing them seem to be the only true fundamentals related to describing and understanding the NCU.  The deep interdependency between G and α (or, say, gravitational and electromagnetic properties of matter) based on the NCU concept revealed here might even point to a path to unification of relativity and quantum theory.
