Astronomer Nicolaus Copernicus develops a theory that Earth and the other planets orbit the Sun, that they were Heliocentric (Sun-centered). What? We're not the center of attention? People are angry. Copernicus doesn't feel thair wrath; he dies right after his ideas are published.

HAS GALILEO GONE LOONY?
It was beautiful night. You look up at a bright round shiny moon. A perfect sphere, right? Wrong. Or so said Galileo Galileo in Padua.
Professor Galileo said our pure moon in not perfect. He claimed he had seen peaks and valleys on the moons and that they are bigger than Earth's! That would mean the moon might be more special in some ways than Earth.
But wait, there's more! Galileo also said that four little star circle jupiter. Stars circling another planet? But every thing supposed to circle around us, the Earth! Had Galileo not learned the lessons of ptolemy? The Church and all other scholars tell us all the stars orbit our Noble planet. It's us us us! Everything is about us! After all, anyone can plainly see that sun and stars cross our sky each day and each night!
But Galileo said he has proof in the form of an amazing experiment. It's called the teliscope, and objects seen through it are magnified more than a thousand times. Planet Earth, we must now consider, might be more ordinary than extraordinary.
During his lifetime the Greek philosopher Aristotle thinks and thinks. Finally he decides that the earth is the center of all existence and that the other heavenly bodies revolve around it in perfect circles. People are happy. We just love this idea of a geocentric (Earth-centered) universe. It makes us feel important.
Alexandria, Egypt, A.D. 127-145
Claudius Ptolemaeus, known as ptolemy, refines Aristotle's ideas but agrees that everything revolves around the earth. People remain happy. After all, it's only right that everything should travel around us. We're that soecial. Besides, there are reference in the Bible that seem to back up geocentric.
