A Brief History of Time by Stephen Hawking
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 there boundaries? Are there other dimensions in space? What will happen when it all ends? 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 possibilities are wondrous and unexpected.
