Modern scientific approach grounds on a search of consistent unification which relates to simplification of our understanding of nature. This was achieved by Newton's relation of Kepler's laws to Earth's dynamics, by Maxwell's unification of electromagnetism and by Einstein's theory regarding electrodynamics, gravitation and spacetime. Further, dynamics of matter's fundamental particles have been successfully described in models which have led to testable and fecund predictions on the basis of Quantum Mechanics and Quantum Field Theories. The technical revolution of the last decades grounds on these models which lead and relate to lasers, NMR tomography, gravitational lensing and colossal high- energy experiments. Fundamental forces are not completely unified nor understood, though. Mass is not explained by Einstein's theory, and standard particles predicted in order to explain the appearance of mass in matter are not yet experimental reality. Also flat rotation curves and Super Novae data point to further, new dynamics. This book introduces these problems and treats them in the light of Induced-Gravity theories, Higgs Mechanism and dual QCD for confinement.
