At the University of Pisa, Galileo questioned Aristotle's widely accepted findings about gravity and physics.
-
His findings on objects floating on water
-
Galileo became interested in astronomy and the cause of tides (sea astronomy)
-
Galileo wrote a letter to Johannes Kepler, stating that he agreed with Copernicus' heliocentric view of the universe.
-
Galileo observed a supernova in space, which went against Aristotle's claim that no change ever took place in the heavens.
-
Galileo saw Jupiter's moons orbiting the planet with his own telescope
-
Galileo published his findings in The Starry Messenger and observed that Venus circled the sun, just as Copernicus thought
-
Galileo published Letters on Sunspots, in which he wrote that he agreed with Copernicus in the appendix. This was the first time he publicly made his opinion known. He included his observations of Venus, the tides, and Jupiter's moons, which he concluded could only occur if the Earth revolved around the sun.
-
Galileo disagreed with the Catholic Church getting involved with matters of science, but the church prohibited Copernicus' book and any books that agreed with it.

Newton discovers that "white" light is composed of all colors and studies calculus and gravity. He famously sat under his grandparents' apple tree and pondered gravity after watching an apple fall. He wondered if the gravitational pull could also apply to the moon to keep it in its orbit.
-
Newton explained the 3 Laws of Motion and the Law of Universal Gravitation. His research led to his understanding of the motion of celestial bodies and the building of a new telescope that used mirrors instead of light. Newton was influenced by Galileo in his first law of motion, and Newton's knowledge of physics, mathematics, and astronomy made a big difference in understanding Earth and the universe.
