This book is about the observation of a subatomic particle switching between matter and antimatter states at a mind boggling 3 trillion times per second. The spontaneous identity fluctuation represents a subtle quantum mechanical phenomenon and its analysis constitutes a high sensitivity probe of Natures fundamental forces. The oscillation offers a glimpse of the development of the early universe, and might shed light on one of the greatest unsolved problems in science: the mystery of matter antimatter imbalance in the universe. Measuring the oscillation and the astonishing rate at which...
