We study a flat three-torus universe whose contraction is turned around by the negative Casimir energy of Standard Model fields. The trace anomaly forbids conformal matter alone to turn an anisotropic universe around, so matter with $w<1/3$, most cheaply a positive potential, must supply the negativ
