center of the universe with the sun, the moon, the stars and the planets orbiting it in perfect circles.
Newton put Kepler and Galileo's ideas together and discovered that the reason that things fall on the ground is the same reason that planets orbit around the sun.
He made a telescope that could magnify
up to 30 times.
<span>He discovered that Copernicus' theory </span>
was true. "We're not the center of the universe."
