Abstract: We consider the electromagnetic resolution of the gravitational field. We show that under the duality transformation, in which active and passive electric parts of the Riemann curvature are interchanged, a fluid spacetime in comoving coordinates remains invariant in character with density and pressure transforming, while energy flux and anisotropic pressure remain unaltered. Furthermore, if the fluid admits a barotropic equation of state, where , which will transform to . Clearly the stiff fluid and dust are dual to each other, while will go to flat spacetime. However, the radiation and the de Sitter universes are self-dual.
