Giordano Bruno

Giordano Bruno was a Neopolitan philosopher, Dominican friar and priest, poet, alchemist, astronomer, cosmological theorist, and esotericist. He is known for his cosmological theories, which conceptually extended to include the then-novel Copernican model. He practised Hermeticism and took a mystical approach to exploring the universe. He proposed that the stars were distant suns surrounded by their own planets (exoplanets), and he raised the possibility that these planets might foster life of their own, a cosmological position known as cosmic pluralism. He also insisted that the universe is infinite and can have no centre.
