A Dyson Sphere is an imaginary type of structure that is created around a star in space, and is featured in many popular books and movies. It is a giant sphere that completely encloses the star and its planets, and is made from many pieces of material that are joined together, like a giant jigsaw. A Dyson Sphere is used to capture the energy from the star, and it is imagined that it could be used to power a civilization. It often appears in science fiction and fantasy stories, where it is used as a source of power or a place of refuge. In movies, it might be used to show the extent of a powerful character or to show a fantastic place. In books, it will often be a place that has “magical” powers or a place that is used to store information and knowledge.
