The proposed article is a development of the topics of gravity, the inverse temperature dependence of gravity forces, the action of the inverse temperature dependence of gravity forces and the second law of thermodynamics, dark matter. All interaction schemes are built on the basis of the laws of classical Newtonian mechanics. In relation to the dynamics of rotation of the matter of the Galaxy, the formation of a lattice of gravity forces is noted. The article provides a comparison of the lattice of gravity forces of the Galaxy and the lattice of gravity forces for the planets of the Solar system. The comparison of these lattices explains the dynamics of these systems. The key point in the comparison is the definition of the rigidity of the lattice of gravitational forces.
