A modified version of the Ozer and Taha nonsingular cosmological model
is presented on the assumption that the universe's radius is complex
if it is regarded as empty, but it contains matter when the radius is
real. It also predicts the values: Omega(M) = rho(M)/rho(c) approximat
e to 4/3, Omega(v) = rho(v)/rho(c) approximate to 2/3 and Omega- = rho
-/rho(c) much less than 1 in the present nonrelativistic era, where rh
o(M) matter density, rho(v) = vacuum energy density, rho- = negative e
nergy density and rho(c) = critical density.
