The first non-fiction picture book in Korea to introduce the cosmos to children.

Can you believe that the vast universe we know began from a tiny point? Just like the universe, children start with small possibilities and curiosity, but we never know how great and magnificent they will become. "Hole" not only provides scientific knowledge but also conveys a philosophical meaning, connecting the universe with us and exploring the significance of our existence.

The book brings to life the vast history of the universe, from the history of Earth, humanity, environmental changes, to historical events leading up to the present, using warm language and vibrant colors and images. By following the holes in the pages and journeying through the history of the universe and Earth, children will naturally expand their scientific knowledge and nurture their curiosity.
