Earth revolves around the sun it does not revolve around us
As Copernicus said the Earth revolves around the sun(Geocentric) but the church said that the sun revolves around Earth(Heliocentric). As punishment the church made him serve house arrest for the rest of his life.
Galileo was looking in space with his new telescope that he got from Issac Newton as soon as he saw Mars he immediately found out that other things can revolve around other planets. He went straight to the church and told the government. The church did not believe him so he also served house arrest for the rest of his life.
Issac Newton came up with his idea when he was sitting against a tree and a apple fell on his head giving him the idea of the reverse telescope. That is how he found out about the three laws of nature.
