| Abstract: | It is shown that perfect fluid space-times can also satisfy the field equations for a magnetohydrodynamic fluid. The necessary conditions for this equivalence are found and the magnetohydrodynamic interpretations of the zero-curvature FRW model with equation of stateρ=3p, and of the Gödel model are given. |
