Ask any theoretical physicist on what are the most profound mysteries in physics and you will be surprised if she mentions anything other than Quantum Gravity and the Dark Sector. Questions such as how do we reconcile GR and Quantum Theory? What is Dark Matter? And what is Dark Energy? These are what keep most physicists awake late at night. Suggested solutions to these problems are manifold but all fall short of providing a satisfactory explanation. The situation is set to change however as a new theory authored by Lic. Stuart Marongwe who holds a licentiate degree in physics and electronics from Jose Varona University in Havana, Cuba now stationed at the physics Department of McConnell College in Botswana, provides a self-consistent theory of Quantum Gravity which explains the Dark sector and is in agreement with observations.
The theory is known as Nexus in the sense that it provides a link between Quantum Theory and GR. This link manifests in the form of the Nexus graviton- a composite spin 2 particle of space-time which emerges naturally from the unification process. One remarkable feature of the Nexus graviton which distinguishes it from the graviton hypothesized in the Standard Model is that it is not a messenger particle but rather it induces a constant rotational motion on any test particle embedded within its confines. Moreover the Nexus graviton can also be considered as a globule of vacuum energy which can merge and de-merge with others in a process that resembles cytokineses in cell biology. The Nexus graviton is Dark Matter and constitutes space-time. The emission of a graviton of least energy by a high energy graviton results in the expansion of the high energy graviton as it assumes a lower energy state. This process manifests as Dark Energy and takes place throughout space-time as the theory explains.
This paper is significant in the sense that it sheds some light on some of the most perplexing questions in physics which include a quantum description of Black Holes without singularities inherent in classical GR.The solutions provided in this paper will certainly open doors to new physics.
