The heliocentric theory directly challenged which model of the cosmos?

• A. The geocentric model that placed Earth at the center
• B. The heliocentric model that placed Earth at the center
• C. The geocentric model that placed the Sun at the center
• D. The heliocentric model that placed the Sun at the center

Answer: (A)

Shifting the center of the cosmos from Earth to the Sun is what this question centers on. The heliocentric theory says the Sun sits at the center and the planets, including Earth, orbit it. That directly contradicts the long-held geocentric view, which claimed Earth is the center of the universe and remains stationary while the heavens move around it. Accepting a Sun-centered arrangement removes Earth’s privileged position and explains planetary motions in a simpler way, which is why this theory directly challenged the geocentric model that placed Earth at the center. Historically, Copernicus提出the heliocentric model, with later support from Galileo and Kepler reinforcing the shift away from Earth-centered thinking.
