  Recent results from cosmic microwave background (CMB) experiments verify
several of the predictions of inflation, while ruling out a number of
alternative structure-formation scenarios. Given the successes of the theory,
the obvious next step is to press ahead and test inflation to the edge of all
our current and forthcoming observational abilities. According to the
inflationary paradigm, galaxies and their large-scale distribution in the
Universe are remnants of inflation and can thus be studied to learn more about
inflation in the same way that experimental particle physicists study the
remnants of high-energy collisions. Here I discuss how studies of galactic
substructure, galaxies, clusters, large-scale structure, and the CMB, may be
used to learn more about inflation.
