Summary: We review the theory of Chaplygin gas. This theory arises from the non-relativistic fluid mechanics with exotic state equation. This condition actually admits that the fluid theory reduces to simple relativistic geometrical objects. This means that the non-relativistic fluid theory has hidden Poincaré symmetry. We show that the geometrical object is the brane described by Nambu-Goto action. The application of this Chaplygin gas to the universe model is also briefly reviewed.
