Eurhythmic Physics is a global approach allowing the unification of physics. Assumes that natural physical phenomena are very complex and that, in general, the whole is different from the sum of the constituent parts. So, to be best described, need a complex inter-relational nonlinear approach. The mathematical formulation of this complex inter-relational and nonlinear physics is mainly done through the organizing principle of Eurhythmy. Eurhythmic Physics leads to a deeper understanding of the physical reality. In such conditions, classical physics, relativity and quantum physics are susceptible of a unique unitary and causal description. Furthermore, allows a deeper understanding of what is commonly called gravitation, gravitic interaction, the concept of mass, and the electromagnetic phenomena. The complex inter-relational nonlinear approach furnishes also the basis for understanding what lies behind the invariance of the velocity of the light in the most common circumstances. The apparent mystery behind quantum tunneling and zero-time transitions is easily clarified when we look at it with the eyes of the New Physics.
