-Geocentric Theory
Earth is the center of the universe; Sun, planets, and stars revolve around it.
Proposed by Aristotle and Ptolemy (2nd century CE).
Relied on epicycles to explain planetary motion.
Aligned with ancient beliefs but became complex and inaccurate over time.
-Heliocentric Theory
Sun is the center of the solar system; Earth and planets revolve around it.
Proposed by Copernicus (16th century) and supported by Galileo, Kepler, and Newton.
Evidence: Phases of Venus, Jupiter’s moons, and elliptical orbits (Kepler).
Simplified and accurate, forming the basis of modern astronomy.
Key Difference
Geocentric: Earth-centered, outdated.
Heliocentric: Sun-centered, scientifically valid.
