This extraordinary nonfiction book takes children on a playful and intuitive journey through the various concepts humanity has imagined about our universe. Every people, every culture, every civilization has had its own idea of our universe and often its own words to describe or tell stories about it. Is the universe flat or more like a round balloon? Who envisioned the sky as a crystal-clear sphere? And is there even a multiverse? From the cosmos of the ancient Greeks to Copernicus's discoveries and Einstein's theories, children can explore wonderful fold-out panels that reveal the astonishing fantasy worlds of diverse peoples and cultures from antiquity to the present. They will learn what can be observed and what theories exist today about the universe. A well-researched nonfiction book tailored for children.
