This article is the eleventh part of the scientific project under the general title "Geometrized Vacuum Physics based on the Algebra of Signatures" (GVPh&AS) [1,2,3,4,5,6,7,8,9,10]. In this article the phenomenon of planetary gravity is considered as a result of a spatial-phase shift between two counter intravacuum flows, flowing top-down and bot-tom-up. These powerful intravacuum flows flow along counter spirals wound on all radial directions departing from the core of stable spherical vacuum formations (in particular, "planets" and "stars"). In this case, the vacuum currents flowing upward along the spiral always slightly lag in magnitude behind the vacuum currents flowing down-ward along the counter spirals. Therefore, a relatively weak residual accelerating drain carries along all bodies in the direction of the core of the spherical vacuum formation, and is the cause of gravitation. The model representation of gravity as a result of the difference of counter powerful intravacuum currents can serve as a theoretical justification for the possibility of using these flows for alternative methods of movement in space. In conclusion, the article considers possible methods of controlling the topology of space and intravacuum currents with the aim of using them as a driving force in the levitation mode.
