Why was giordano Bruno burned alive in1600?

Giordano Bruno was burned alive in 1600 primarily for heresy, as he challenged the Catholic Church's teachings and promoted ideas that contradicted its doctrines. He advocated for the existence of multiple worlds and the infinity of the universe, which clashed with the geocentric view held by the Church. His refusal to recant his beliefs during his trial ultimately led to his execution in Rome. Bruno's martyrdom has since symbolized the conflict between free thought and religious orthodoxy.
