This book is written for advanced researchers, doctoral students, & theoretically inclined physicists who seek a testable, empirically grounded alternative to mainstream Quantum Gravity (QD) programmes. It suits cosmologists who want a resolution to the Hubble tension that does not rely on fine - tuning or new exotic fields; particle physicists who demand first - principles derivations of hadronic radii & force ratios; & philosophers of science interested in how paradigm shifts occur through predictive success rather than mathematical elegance. Doctoral candidates will find later chapters especially valuable: ten concrete, well-defined research projects ranging from formalising the absence of graviton self-coupling to translating MathCad algorithms into open-source Python tools. The book serves as a comprehensive reference for the Electro-Gravi-Magnetic (EGM) Construct, but it is also a safety-net for students struggling to find original, tractable problems grounded in a framework that has already demonstrated genuine a-priori predictions (most notably the 2008 forecast of the Planck Hubble constant, confirmed in 2013). It is not introductory; a working knowledge of General Relativity (GR), Quantum Field Theory (QFT), & Dimensional Analysis Techniques (DAT’s) is assumed. However, for those willing to engage with an unconventional but internally consistent paradigm, this book offers both a complete derivation of the framework, & a roadmap for extending it.
