内容简介

Scientists believe that we would not be here if it were not for three great cataclysms in the early history of the universe. This book explores the connection between these events--the "Big Bang" that spawned an entire universe; the explosion of a supernova which seeded the solar system with elements; and the crash of a comet or asteroid that caused the demise of the dinosaurs, clearing the way for the evolution of mammals.
