Abstract:
During researches, I came to conclusion that any physical object is internally infinite, andthat anyspace is represented by the matter. Hence, the orbital motion is realized via thin medium. I provide a critical review of concepts of Descartes, Newton and modern viewpoint. I provided some simple experiments, checking two concepts. Iassume that orbital motion is caused by both equilibrium of pushes from dif erent sides of interacting object, andbydisplacement of all the system of these bodies.
