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.
Galileo's support for the heliocentric theory (note that this is Copernicus's theory, not Galileo's) got him into trouble with the Roman Catholic Church. In 1633 the Inquisiti â¦ on convicted him of heresy and forced him to recant (publicly withdraw) his support of Copernicus.e was an Italian scientist of the 17th century. He did not prove  the heliocentric theory. But everyone accepts the heliocentric  principle now, after it was proved right; â¦ but that happened long  after Galileo's time, after new scientific discoveries in the  latter half of the 1600s.
