The Origin of Large-Scale Structure

There are strong reasons to believe that the fluctuations which seeded the large-scale structure of the Universe must have been primordial in origin, that is, associated with some of the very earliest times after the Big Bang. The primary candidates at the present time are (1) topological defects, such as cosmic strings and textures, or (2) inflationary scenarios. This page is under construction, but for a direct comparison between these models refer to the origin of fluctuations in the cosmic microwave background radiation.
