    Now, in everyday language, Stephen Hawking's Universe reveals step-by-step how we can all share his understanding of the cosmos, and our own place within it. Stargazing has never been the same since cosmologists discovered that galaxies are moving away from each other at an extraordinary speed. It was this understanding of the movement of galaxies that allowed scientists to develop a theory of how the universe was created—the Big Bang theory. Working with this theory, Stephen Hawking and other physicists felt challenged to come up with a scientific picture that would tackle the fundamental question: what is the nature of the universe? Stephen Hawking's Universe charts this work and provides simple explanations for phenomena that arouse our curiosity.
