Superstring theory is one popular candidate for tying all of physics into one unified theory. In the theory, particles actually consist of vibrating loops of "string." For the mathematics to work, the universe would actually consist of 10 spatial dimensions, not the three dimensions we observe in everyday life. The extra seven dimenions have "rolled up' out of sight.
