On Lorentz-invariant Theory of Gravitation Part 2: The Nature of Pre-spacetime & Its Geometrization

Abstract

In the modern theory of gravity - general relativity - the cause of the gravitational field is the curvature of space-time, which is not a material object. The question of, how non-material space-time can cause a material gravitational field is still here unanswered. In the framework of proposed electromagnetic theory of gravitation, which is based on the nonlinear theory of elementary particles (NTEP), it is assumed that there is a material carrier, whose characteristics allow us to introduce the concept of space-time, uniting general relativity and quantum field theory. This medium we conventionally call "pre-spacetime." The purpose of this paper is to determine the nature of pre-spacetime and methods for its geometrization.
