The five chapters of this title from the "Great Ideas in Science" series reveal the detailed mysteries related to the origin and evolution of the universe for young enthusiasts. Early in the 20th century scientists set aside myths and guesswork by developing tools, making observations, and developing the theory that the entire universe was created in a single instant fourteen billion years ago and continues to evolve at a constant rate. The cosmological principles of noted philosophers, physicists, and astronomers (including Aristotle, Copernicus, Einstein, Hubble) are revealed in each succeeding chapter that include hands-on models, graphs, charts, a glossary, sidebars, and snapshots to ensure the reader grasps challenging concepts that are presented. The final two chapters help readers predict the fate of the universe by exploring its three possible shapes—closed, open, and flat—and then offer challenges with questions yet to be answered. A time line briefly traces historical events; brief biographies provide insights into scientists' backgrounds and discoveries; and a selected bibliography, a list of further reading, and exceptional web sites enhance the topic. The material presented in this title is quite complicated. Introduce the subject matter using Seymour Simon's Universe and Big Bang!: The Tongue-Tickling Tale of a Speck that Became Spectacular by Carolyn Cinami DeCristofano. The intrigue of space, galaxies, light years, planets, and nebula always fascinates young readers.

Gr 6-10-The Big Bang theory states that the universe emerged in a single explosive event. This book attempts to explain this complex and abstract concept. It begins with a historical overview, then presents Albert Einstein's theory of general relativity and Edwin Hubble's observations of retreating galaxies, and continues with additional evidence. The author acknowledges that many questions still need to be answered. The book offers a few interesting analogies and includes 22 color diagrams, photos, and informational sidebars. A solid addition for introductory reports.-Carolina Geck, Kean University, Union, NJ Copyright 2005 Reed Business Information.
