A causality based model meant to integrate all issues not resolved with Special Relativity and General Relativity by integrating a relativistic effect in nucleons not taken into account by either theories, and that reconciles Quantum Mechanics with causality. **** Electromagnetic Mechanics of particles (EMM) Description of a new space geometry that allows explaining the existence of all stable physically scatterable particles, relativistic velocities and gravity solely from Maxwell's electromagnetic theory and that consequently opens up a new and very promising avenue of research. Even though it allows defining an electromagnetic mechanics of particles paradoxically requiring neither underlying fields nor any vacuum medium of any sort, this integration remains in perfect harmony with the equations of Special Relativity, Quantum Mechanics and Quantum Electrodynamics with minor adjustments. All electromagnetic properties usually associated with underlying fields become direct properties of each individual elementary particle. While classical, relativistic and quantum mechanics describe the motion of bodies and particles, this electromagnetic mechanics proposes a description of their fundamental nature and an explanation to the cause of their motion and the reason why they naturally tend to selfpropel at constant velocity and selfguide in straight line when no external force is acting on them, on top of possibly revealing a new and apparently inexhaustible source of energy. A new physics that provides a quite unexpected solution to the magnetic monopoles issue and naturally explains in a novel manner light deflection, atomic stability, the electron magnetic moment “anomaly”, the so-called time dilation, Earth’s rotation rate slowdown, the Moon orbit expansion, Mercury's orbit precession, the two “so-called” anomalies of the trajectories of both Pioneer 10 and 11 spacecrafts by integrating a relativistic effect not yet taken account of in SR and GR, that is nucleon dilation, resulting in their rest mass variation as a function of the local gravity gradient intensity.
