The main characters in the book are George Greenby, Susan Bellis, Eric Bellis, Annie Bellis, Dr. Reeper, and Cosmos, the world’s most powerful computer. Cosmos can draw windows allowing people to look into outer space, as well as doors that act as portals allowing travel into outer space. Written like a story, it aims to describe various aspects of the universe in a manner that is accessible to children and others new to the topic. It starts by describing atoms, stars, planets, and their moons. It then goes on to describe black holes, which remains the topic of focus in the last part of the book. At frequent intervals throughout the book, there are pictures and “fact files” of the different references to universal objects, including a picture of Mars with its moons.
George’s Secret Key to the Universe
George’s pet pig breaks through the fence into the garden next door – introducing him to his new neighbours: the scientist, Eric, his daughter, Annie, and a super-intelligent computer called Cosmos. And from that moment George’s life will never be the same again, for Cosmos can open a portal to any point in outer space . . .
