    On the Theoretical Foundations of the Polemical Titius-Bode Law (Ii) Exoplanetary Systems
    (ResearchGate, 2018-06-10) Nyambuya, G. G.; Jigu, D.; Nyathi, A. N.; Dube, A.; Sibanda, B.; Musosi, G.
    Using the Solar system as our standard calibration system, we device a ‘one-size-fits-all ’ procedure to fit exoplanetary semi-major axis onto ‘quantized’ nodes relative to their central host star. The idea is to fit the exoplanet’s semi-major axis onto quantised exponential orbits using the derived exponential planetary placement law (an = R5e 5n : n = 1, 2, 3, · · · ). We herein ‘fix’ the two free parameters (R5, 5) from theory so that, one should – in general – be able to calculate from theory the expected placement of a planet given the mass (Mstar) and radius (Rstar) of the host star. Using twenty five exoplantary systems with at least four known planets, we demonstrate that one can – on a very satisfactory level, ‘fix’ the two free parameters (R5, 5), so that they depend on Mstar and Rstar. Consequently, this strongly suggests that the Titius-Bode Law – a curiosity, usually assumed to be a result of chance – may very well be a gravitational phenomenon.

    Salvaging Newton’s 313 Year Old Corpuscular Theory of Light.
    (2017) Nyambuya, G. G.; Dube, A.; Musosi, G.
    As is well known – Newton’s corpuscular model of light can explain the Law of Reflection and Snell’s Law of Refraction. Sadly and regrettably – its predictions about the speed of light in different mediums runs contrary to experience. Because of this, Newton’s theory of light was abandoned in favour of Huygens’ wave theory. It [Newton’s corpuscular model of light] predicts that the speed of light is larger in higher density mediums. This prediction was shown to be wrong by Foucault’s 1850 landmarking experiment that brought down this theory of Newton. The major assumption of Newton’s corpuscularmodel of light is that the corpuscles of light have an attraction with the particles of the medium. When the converse is assumed, i.e., the corpuscles of light are assumed to not have an attraction-effect, but a repulsion-effect with the particles of the medium, one obtains the correct predictions of the speed of light in denser mediums. This new assumption [of Newton’s corpuscles repelling with the particles of the medium] might explain why light has the maximum speed in any given medium.

    Wave Equation in a Reactive Medium and the Origins of Inertia
    (2017) Nyambuya, G. G.; Musosi, G.; Dube, A.
    We herein derive an equation for a wave travelling in a reactive medium, that is to say, a medium which interferes with the travelling wave. The purpose of this derivation is to try and obtain new insights into the origins of the mass term appearing in the quantum mechanical Klein (1926) and Gordon (1926) equation. From the derived equation, it very strongly appears that one can safely entertain the idea that inertia may very will be a result of the interaction of space with the traversing quantum mechanical wave packet – the particle. Insofar as the generation of mass via the interaction with some all-pervading and all-permeating cosmic field, this idea of a reactive medium fits handin- glove with the Higgs mechanism which postulates a Higgs field which must fill all space and via the interaction of this Higgs field with matter, the inertia properties of matter are derived
