This book sketches in detail, in its first part, some possible intriguing suggestions in order to conceive, and deal within a unified scheme, the dual aspects of particle and wave coexisting and conflicting in theoretical physics from the beginning of the 20th century, so opening a door to a deep harmonization of Relativity and Quantum Mechanics. And in the second part it presents a new approach to field unification, including gravity, together with the standard model of elementary particles and scalar boson, within the frame of multidimensional general relativistic universe. Cosmological application of the proposed theory involves non-trivial predictions about the still unexplained universe flatness, dark matter and dark energy. A way to gravity quantization appears also practicable.
