This planetarium show is based on the story "Chi. - About the Movement of the Earth," set in 15th-century Europe and depicting the struggles of those who risked their lives to pursue the heliocentric theory. The story follows the prodigy Rafau, who meets Hubert, a scholar imprisoned for heresy, and learns of a groundbreaking theory about the universe. The immersive planetarium presentation brings to life the grand history of astronomical research, from early studies of the heliocentric model to the latest discoveries in modern astronomy.
