This book's images of space and objects floating or falling therein are hypnotically arresting. However, the science here is oversimplified to the point of inaccuracy. Objects do not "have gravity"; they have mass. To say "without gravity, everything would float away" misses the essential point--without gravity there would be no anything to float anywhere. Appended "More About Gravity" provides fuller explanations. Bib.
