The original sketch in 2014, full of typos, for historical sake10 years ago, I stumbled upon the Randall-Sudrum cosmological model (also called 5-dimensional warped geometry theory) that describes the world in terms of a warped-geometry higher-dimensional universe, or more concretely as a 5-dimensional anti-de Sitter space where the elementary particles (except the graviton) are localized on a (3 + 1)-dimensional brane or branes. The model is a braneworld theory that involves a finite five-di...
