Controversial findings

He found that the earth and moon revolve around the sun which went against the theory that the earth was the center of the universe. This really angered the church to the point where they threatened to kill him if he didn't take back what he said about his findings. He also found that the moon wasn't a perfect sphere which went against Aristotle's idea that they were.

Galileo made the first telescope. He used this to see that the moon isn't a perfect sphere and Jupiter's moons. He also made the theory of the Copernican system which apposed the original theory that everything orbits Earth.

I learned he was actually a university professor. This person is historically significant because he changed the way we look at science and mainly our solar system. He discovered the moons of Jupiter,the craters of the moon, and that we revolve around the sun not the other way around.
