The genesis and structure of models in the modern theory of gravity

Abstract

The analysis of theory‐choice problems in modern theory of gravity necessitates consideration of the genesis and structure of the systems of gravitational abstract objects. My approach to physical theory structure uses and develops the ideas of V. S. Stepin. The fundamental equations of general relativity Einstein's equations ‐ are shown to describe the relations between the abstract objects of the basic model only. The theory of gravity chain consists of general relativity, nonmetric theories of gravitation, Newton's theory of gravitation and the special theory of relativity. All these theories describe the relations between the abstract objects of partial models subordinated to the basic one.
