So what did this mean in layman

  I'm a physicist but this isn't my field, so I will comment with my understanding, which may be wrong. Usually we expect that on a large scale there should be a uniform structure across the universe, i.e. the universe should be homogenous on a cosmic scale. Galaxies should be for the most part evenly distributed across the universe since everything came from a singularity at the big bang. The reason why we see any asymmetry on a small scale, e.g. we see galaxies and stars and planets form, is because of comparatively "microscopic" effects of physical laws. E.g. clusters, galaxies, stars, and planets form because they overcome the expansion of the universe, but generally the matter should be distributed evenly on a big enough scale. This result is very interesting, because it implies some kind of asymmetric structure of the universe on a huge, cosmological scale. But how can such a structure arise? What causes such a structure to arise?
