Giordano Bruno, born January or February 1548 - 17 February 1600) was an Italian Dominican friar, philosopher, mathematician, poet, cosmological theorist. He proposed that the stars were distant suns surrounded by their own planets, 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 could have no "center" or simply, i.e. universe is infinite. For this, he was labeled a heretic and later executed. His death resulted in his becoming a symbol for free thought, free speech, and science.
