solar+theoriesHendk

In this lesson i was show that in the older times there was two theories about the sun and the earth. These theories were called The heliocentric model and the geocentric model.The heliocentric model is about the sun, This theories was that everything was around the sun, that the was the center of everything. In the older times they thought that it was a sun centered universe and they made models of it to prove that they were right. But as time went by they found out that it wasn't a sun center universe but that it was a sun center solar system. They wanted to found out if that it was true with proof. So one of the scientist made telescope that could see into other solar system. The geocentric is the theories about the earth being the center of the universe. It was pretty easy for people to believed that the earth was the center of everything because we lived on the earth. They all thought the the sun was in the center because if the sun moved then the stars would change. But as time went by the soon relived that the earth was not in the center but the sun was.
