The 14-year-old student Cary Huang from California had the idea during the lessons to deal with the proportions in his environment, the earth, our solar system and the universe. The result was a fascinating journey from the smallest building blocks of the universe to the limit of observable space. Step by step you can zoom back and forth between the different scales and learn not only how small the distance from the earth to the sun is on a cosmic scale, but also that the Tyrannosaurus Rex was smaller than the largest cactus in the world.
