Query: Gravity, matters and dark energy on the minimal surfaces   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.
