First, the observations are consequences of the universal principle of horizons and virtual motions of a system of spaces' horizons, which limits observations and interactions. Then, time is stroboscopic with periodical times of observation or interaction and periodical times of non-observation or non-observable interaction. This theoretical model dispose of basic notions and principles, however it never disposes of the existing laws. It introduces a set of periodical motions of embedded horizons, which would be fundamental for physics, as well for quantum mechanics as for relativistic mechanics. An application to the solar system (Garnier-Malet J.P., 1998) gave us the understanding of the physical reality of this geometry. It allowed us to explain in another way Kepler's three laws and the motion of planetary libration. lt also allowed us to rediscover the condition of the relativity theory in the solar system (the precessional motion of Mercury's orbit). This new model implies one solar cycle (24 840 years), which is going now to end (2017). Above all, it causes a junction between our solar system and the speed of light, which I could calculate in a theorical way. It gives me now the capability to propound a new theorem, which is already verified by two important astronomic observations.
