Solar System

Geocentric Theory:
- The Geocentric Theory states that the earth is the center of the universe. Astronomers found evidence that the rest of the universe moved about a stable. The Astronauts saw the planets, moon, sun, and stars move around earth on certain paths every day (This includes Mercury, Venus, Mars, & Jupiter which was only known at the time). So the astronomers concluded that the earth did not move (stationary). This all took place from the Greeks until the 1500's.

-Heliocentric
Heliocentrism is the theory that the sun is at the center of the solar system. It looks obvious to people the the earth stays in one place and the sun and moon just rise and set and goes around. scientists that studied science for a long time discovered other movements. According to the Heliocentric theory the sun makes a slower circle over the course of a year. The planets also, as well, have similar motions, but they sometimes turn around and move in reverse direction for some time.

-Galileo
- Galileo was sent to court going against his book which was released in 1609 Which stated that the earth revolves around the sun. His book stated something totally opposite from the bible, or at least what the pope believed. Which is that the sun revolves around the earth. Galileo was arrested, tried, & convicted for the crime of disobeying the church & using science instead of religion to explain the universe. The reason Galileo was arrested was because the pope was fearful that people would start to challenge other church teachings. The pope also banned all catholics from reading his book. In 1991 the church admitted that it had been a mistake jailing Galileo.
