Copernicus and the trial of Galieo

There was a theory called Heliocentrism and it was said that the sun is in the center on the solar system. This theory was was fullly presented by an astronomer Nicolous Copernicus, was later elaberated by Johannes Kelper and Galileo defended it. It bacame a huge debate.

There was also the old geocentric theory that the earth was place at the center of the solar system. This theory came from the Scentific Revolution. Nicolous Copernicus soon replaced this theory with the heliocentric theory saying that Earth was just one of the planets orbiting the sun.

The Catholic Church had put Galieo on trial because he promoted to idea of Earth not being the center of the solar system in a book. Galieo believed that the Sun was the center of the Solar System while the Catholic Church believed that Earth was the Center of the Earth.
