Query: Comments on an alternative theory for the accelerating universe   We utilize the recently released supernova data of Riess {\it et al.} on the
acceleration of the universe to determine how the parameters of a particular
modification of gravity, the DGP 5-dimensional theory, are changed when
compared to determinations using earlier data sets. We show the parameters of
the theory are now very tightly constrained and at very reasonable values. For
example, the curvature parameter, $\Omega_k$, in contrast to an earlier
analysis which used a smaller data set, is now consistent with zero, and the
redshift at which the universe starts to accelerate is near unity.
