On the secular recession of the Earth-Moon system as an azimuthal gravitational phenomenon

“…Moffat 1995Moffat , 2005 and the extra-anomalous apsidal precession of Solar planetary orbits (Iorio 2007b(Iorio , 2007c(Iorio , 2008. The fact that in Nyambuya (2014c), this potential is derived from within an acceptable framework of gravitomagnetism, this justifies not only its application in gravitational physics but its existence in the gravitation physics.…”

“…In Sect. 4, we present a summary of the work presented in Nyambuya (2014c). This work is presented in context which gives its relevance in the present reading and in Sect.…”

“…That is to say, this theory (ASTG-model) is (in our modest view) a natural extension and next logical step in the development of Newtonian gravitation (and perhaps an alternative to the GTR). Actually, this theory is part of a much larger model of gravitomagnetism (see Nyambuya 2014cNyambuya , 2015c. At first glance, this theory (ASTG-model) appears as nothing more than the mundane azimuthally symmetric solutions of the well known Poisson-Laplace equation, namely:…”

On the plausible origins of the spiral character of galaxies

“…Perhaps, we mustat this jucture before we present our conclusion -hasten and say that, this FPLTG-model presented in the reading Nyambuya (2015b), is actually a reincunation of the Finnish theoretical physicist -Gunnar Nordström (1912)'s relativistic theory of gravitation which is believed to be the first failed relativistic theory of gravitation (see e.g., Weinstein 2015;Norton 2007Norton , 1992. In the reading Nyambuya (2019a), we have argued that Nordström (1912)'s relativistic theory of gravitation can be reconsidered back into the fold of variable gravitation theories.…”

“…In the model under consideration [Paper (I) and (II)], the flat rotation curve problem common or prominent in spiral galaxies is here explained by means of a new force that we have coined the gravitational dark-force (and here symbolized as F D ). This gravitational dark-force has been shown in the readings Nyambuya (2019bNyambuya ( , 2015b to arise from Nordström (1912)'s relativistic theory of gravitation. Further, the gravitational dark-force comes in as an addition to the Newtonian gravitational force: F N = −GM gal mr/r 2 , that is to say, if Fres is the resultant gravitational force acting on a test particle orbiting the galactic bulge, then, in accordance with Newton's Second Law of Motion, we know that:…”
