The last several chapters deal with a conundrum called the Ozma Problem, which examines whether there is any fundamental asymmetry to the universe. This discussion concerns various aspects of atomic and subatomic physics and how they relate to mirror asymmetry and the related concepts of chirality, antimatter, magnetic and electrical polarity, parity, charge and spin. Time invariance (and reversal) is discussed. Implications for particle physics, theoretical physics and cosmology are covered and brought up to date (in later editions of the book) with regard to Grand Unified Theories, theories of everything, superstring theory and M-theory.
