<em>People thought that the earth was the center of the universe and everything revolved around it, but people like Galileo disproved this and changed the way people understood the universe and were the ones to say the earth revolves around the sun. He also showed the planets revolve around the sun-or a new way of thinking. But when Galileo was trying to make people see the universe a different way Galileo has now finally discovered evidence to support Copernicus’ heliocentric theory when he observed four moons in orbit around Jupiter. Galileo confirmed Copernicus's theories on the universe by noting that the Earth did indeed revolve around the Sun and not the other way around as was thought at the time. With this, he opposed the church dogma at the time. </em>
