(stars), and Heaven

Galileo on Trial
• Galileo’s findings frightened the Church
and the Pope.
• They were against Church teachings
and authority.
• Published a book that presented the
ideas of Copernicus.
• The Pope ordered him to stand trial.
• 1633- He stood before the court and
under the threat of torture, he knelt
before the Church and read a confession
agreeing that the ideas of Copernicus
were false.
• Isaac Newton – tied together
Galileo’s, Kepler’s, and
Copernicus’s theories
• Universal law of
gravitation – every object
is attracted to every other
object through gravity

of blood (arteries and
veins), and that the liver
pumped the blood
