The Solar System is analysed in the framework of the Complete Relativity theory (by the same author). While the main focus is on the Solar System, hypotheses are presented (and tested) on the origin and evolution of planetary systems in general, but also on the evolution of galaxies and the whole observable universe. The analysis confirms the postulates and hypotheses of the main theory and the hypotheses presented here with a significant degree of confidence. Some of these are: relativity in the invariance of physical laws (i.e., existence of discrete vertical energy levels, where each discrete scale of energy effectively represents a universe, associated with the universal running of couplings) and complete relativity in everything, Solar System is a large scale (inflated, in some interpretations) quantum system (Carbon/Beryllium isotope equivalent) with a nucleus in a partially condensed state and components localized in various horizontally and vertically excited states, life is everywhere (e.g., Earth is a particle, but also a living being), although the presence of extroverted complex forms on the surfaces of celestial bodies is generally very limited in time, anthropogenic climate change is only a part of a major mass extinction event (although humanity definitely has a role, the sense of control is an illusion), major extinction events on a surface of a planet are relative extinctions, may be a regular part of transformation and migration of life (not necessarily complex living individuals) below the surface in the process of a planetary equivalent of embryonic neurogenesis.
