On the Infinite is one of Bruno's most insightful cosmological works. Written in 1584, it argues for a boundless, infinite universe, containing innumerable planets, all of which are inhabited. This was a revolutionary idea for the day, opposed to the traditional Aristotelian model of a unique Earth-centered system, encapsulated within a set of planet-bearing crystalline spheres, and surrounded by an outermost sphere of fixed stars.
Bruno's ideas and struggle with the Church authorities were recently featured on an episode of Cosmos, and excerpts from the book
