The Constitution was a compact â though Federalists and Anti-Federalists disagreed over whether the states or the people were the agents of the compact. In September of 1787, it was sent to the states for ratification.
The Heliocentric Theory was first thought of by Aristarchus of Samos. Heliocentrism is the proposal that the Sun is the center of the Solar System. This opposed the notion of Geocentricism, which suggested that the Earth was the center of the Solar System.
His heliocentric system put the Sun (helio) at the center of our system. He was not the first to have this theory. Earlier starwatchers had believed the same, but it was Copernicus who brought it to the world of the Renaissance and used his own observations of the movements of the planets to back up his idea.
