Quinta Essentia: A Practical Guide to Space-Time Engineering (the series), describes the development of a mathematical method termed "Electro-Gravi-Magnetics" (EGM). This text, Part Two of the "Quinta Essentia" series, is a summarised presentation of the key results and findings of Parts Three and Four. The EGM method generates new predictions and confirms well-established experimental observations, particularly in the fields of Particle-Physics and Cosmology. It is our explicit hope that the material presented in the "Quinta Essentia" series, will inspire new ideas and experiments dealing directly with matter-space-time modification, by either applying EGM methods or through the development of oneÕs own approach.
