We show that the quantum behavior of the radiation-dominated flat Friedmann-Robertson-Walker (FRW) universe can be reproduced by classical cosmology given that the universe is filled with an exotic matter. In the case of a fluid, we find an implicit equation of state (EOS) which asymptotically approaches $p=\rho/3$, showing consistency with the classical model. In the case of two non-interacting scalar fields, where one of them is of the phantom type, we find their potential energy. These scalar fields behaves asymptotically as radiation.
