Last name: Guerra. This unusual and interesting surname is of Old French pre 9th century origins. Recorded in many spellings including Guerre, Guierre, Laguerre (French), Guerra, Guerrero, (Spanish), Guerreiro (Portugese), Guerri (Italian), Guerriero (Sicillian), and Warr or Warre (English), the name derives from the word 'guerre' meaning 'war'.
Instead, Galileo disproved the Ptolemaic theory, sanctioned for centuries by the Church, which held the Earth to be the central and principal object in the universe, about which all celestial objects orbited.
against Galileo, the Church condemned nine sentences in Copernicusâ book, including 10 lines of the preface, and required the publication of an expurgated version. Galileo was a proponent of Copernicusâ system. In 1613, Galileo wrote to Father Benedetto Castello, a monk and mathematician, defending Copernicus.
