A Theory of Gravity in Minkowski Space

Abstract

We propose a theory of gravity in Minkowski space. The basic idea is that the presence of mass affects the world line of particles in flat Minkowski background. Although General Relativity is in complete agreement with observations so far, the theory discussed in this paper can solve some of the conceptual difficulties of GR, such as the energy problem, that is at the core of constructing this theory. We also discuss the cosmic expansion of the present universe and comment on the early universe. Furthermore, we demonstrate how the flatness problem and horizon problem are solved within this framework. As it will become clear, this is a theory of principle and not a theory of construction.
