Study Notes
- Geocentric theory claims all planets orbit around Earth, while heliocentric theory states that all planets orbit around the Sun.
- Copernicus first suggested the heliocentric theory, facing opposition from scientists who upheld the religious belief that Earth was the center of the universe.
- Galileo Galilei, using an astronomical telescope in 1609, observed the planets and concluded that it was the Earth orbiting the Sun.
- Despite facing disbelief and being declared guilty by the Inquisition, Galileo stood by his theory and never wavered in his conviction.
- Later scientific evidence from Kepler and Newton supported Galileo's heliocentric theory, solidifying his contribution to our understanding of the universe.
Explore the history behind the heliocentric theory, from Copernicus to Galileo and the scientific evidence from Kepler and Newton. Learn about the challenges faced by these scientists in proving that planets orbit around the Sun.
