The idea of the universe with a mirror sector having all particles and forces identical to those in the familiar sector has been proposed in the context of neutrino physics as well as superstring theories. Assuming that all the quark and charged lepton masses in the mirror universe are scaled by a common factor, ζ, as is required in one interpretation of the neutrino data, we investigate domains of the parameter ζ where physical conditions are favorable for cooling in the age of the universe that can lead to the formation of compact structures given the initial condition ΩB ≃ Ω ˜ B ( ˜ B denoting the mirror baryon). In particular we ask whether there is a region in 1 Work supported by the National Science Foundation Grant #PHY-9119745 and a Distinguishe
