One of the things I firmly believe is that the universe has fractal self-similarity regardless of scale. And now there is some more proof of my belief: Scientists See Universe in a Grain of Sand. There are ways in which the universe replicates itself at higher levels of complexity. We need to learn what these are. One good reason for doing so has to do with social issues. We are also part of the phsyical universe, and we should not be surprised if, when we try to go against nature, whether it be our behaviors that develoepd through evolution, or our ways of ordering and structuring based upon the fractal geometry of the universe, things don't turn out well.
