• In the 1500s, Copernicus proposed a new idea
  the sun is the center of the universe.
• Kepler built on this idea by suggesting that the
  planets orbit elliptically, not in circles.

Galileo Galilei

• By building a more powerful telescope, Galileo
  gave proof to the Copernican theory that the sun
  is the center of the universe.

  by the Inquisition and put under house arrest for
  the rest of his life.

Isaac Newton

• By watching an apple fall from a tree, Newton
  came up with the idea of gravity.
• He stated all physical objects have a force
  between them, and the amount of force depended on
  their masses and the distance between them.
• This theory helped prove the theories of the
  universe by explaining why planets and moons stay
  in orbit.
