What does the "relativity of geometry" mean? It means that the statement: "a certain geometry holds for space" is meaningless. There is not only one geometry, but a plurality of non-Euclidean geometries (although the term refers to hyperbolic and elliptic geometry). What geometry will we apply to the physical space? There, the geometry will return to its starting point of its empirical origin. Experiments will be carried out as in all sciences, and the results of measurements will determine the geometry of the physical space.
