A landmark volume in science writing by one of the great minds of our time, Stephen Hawking's book explores such profound questions as: How did the universe begin--and what made its start possible? Does time always flow forward? Is the universe unending--or are their boundaries? Are there other dimensions in space? What happens when it all ends? Told in language we can all understand, A Brief History of Time plunges into the exotic realms of black holes and quarks, of antimatter and arrows of time, of the big bang and a bigger God--where the possibilites are wondrous and unexpected. With exciting images and profound imagination, Stephen Hawking brings us closer to the ultimate secrets at the very heart of creation.
