There is an analogy of the phenomenon of curvature of space by mass. It is a sheet of rubber with the some mass placed on it. Then the deepening on a sheet is formed and all surrounding objects with only smaller (?) mass should sliding down to the mass lying on a deepening bottom. This model is intended for evident demonstration of an origin of a gravitational field existing around of mass. However this model does not take into account a mutual character of attraction between masses. If consider such masses as the Earth and a tennis ball then their interaction is entered excellently in a drawn picture. But if consider interaction of two equal, for example, masses then this model does not work completely. Each of masses are in the own deepening of a sheet and there is not any reason for their mutual attraction. Normally, they should meet on the middle of a distance between them. Even to admit one mass is placed in a deepening of a sheet and another one is placed on a flat part of a sheet on the edge of a slope, it is impossible to present a picture then mass is rolled out from a deepening and meet another one on the middle of a slope. It turns out so, that the curvature of spacetime in the mass area really exist, but this curvature doesn’t acts directly as attraction force between masses. So, how this contradiction can be explained? Thanks.
