A De Sitter-Hubble Equation, the Force in Special Relativity and Some Concepts on Symmetry

Abstract

Previous works [1] [2] proposed several relevant characteristics of the Hubble field such as the intensity Γ H , potential V H , force F H , Poisson equation, energy E H and a tensor (T μ ν ) H as well as Ricci and Hubble scalars. In this paper, it is made a proposal for two new ones: the kind of the Hubble field as well as a De Sitter-Hubble equation. Moreover, it is proposed a necessary change in the equation of force in Special Relativity. It is included a paragraph on the search for Symmetry in Physics, Chemistry and Time. Conclusions mention an eventual mirror image both the intensity of the Hubble and gravitational fields as well as the relative impossibility for a Big Crunch.
