Gravity, matters and dark energy on the minimal surfaces

Abstract

We propose gravity, matters and dark energy may be confined on different four dimensional \emph{minimal surfaces} for the observer in five dimensional spacetime. Following this idea, we construct the equations of motion when gravity, matters and dark energy are confined on different minimal surfaces. Then in the background of Friedman-Robertson-Walker universe, we investigate the cosmic evolution when gravity and quintessence are confined on the minimal surfaces.
