  The age of the universe is obtained in a subset of Cardassian models by using
WMAP data. Cardassian expansion is a modification to the Friedmann equation
that allows the universe to be flat, matter dominated, and accelerating,
without a vacuum component. Since this model changes the evolution of the
universe, we should not a priori expect the Cardassian age to be the same as
the WMAP Friedmann derived result of 13.7 +/- 0.2 Gyrs. However, in the subset
of Cardassian models we consider, we discover that the age of the universe
varies from 13.4 - 13.8 Gyr over the range of parameter space we explore, a
result close to that of the standard Lambda Cold Dark Matter model. The Hubble
constant h, which may also vary in these models, likewise varies little from
the Friedmann result.
