Giordano Bruno (Nola, 1548 – Rome, 1600) was an Italian astronomer, philosopher, mathematician and poet. His theories of the cosmos were based on Copernicus’s model. He put forth that the Sun was just a star and that the universe must have contained an infinite number of inhabited worlds. He asserted that space and time were infinite. Because of his theological standpoints, the Catholic Inquisition accused him of heresy and he was burnt at the stake.
