Beyond the Big Bang presents a new cutting-edge theory from a pioneering scientist about the origins of our universe. ;;Professor Laura Mersini-Houghton takes the reader through a brief history of ideas about the universe from ancient Greece to the latest frontiers of theory and observation, in which the author has been a leading participant, to bring us to her theory that our universe is not just one isolated phenomenon, but one of many, part of what she calls "the multiverse". ; ;Blending the personal with the theoretical, the book will explain in layman's terms Mersini-Houghton's theory of the origin of our universe and how she came to it. If Mersini-Houghton is proved to be right, the Big Bang theory will be just one other discredited theory and her new theories about the multiverse will represent a paradigm shift as significant as the Copernican Revolution that upended the Ptolemaic model of the heavens, which described the cosmos as having the Earth as the centre of the universe. ; ; Beyond the Big Bang completes the story of the before and after the Big Bang by addressing key questions about the origin of the universe and what was there before.
