Heliocentric said that the sun was the center of the universe, while geocentric said that Earth was the center and everything revolved around it

Answer 1

The correct explanation is: Heliocentric said that the sun was the center of the universe, while geocentric said that Earth was the center and everything revolved around it.

To clarify:

• Heliocentric theory: This model, proposed by scientists like Nicolaus Copernicus, posits that the Sun is at the center of the solar system, and the Earth and other planets revolve around it.

• Geocentric theory: This ancient model, which was prominent in the works of Claudius Ptolemy, argued that the Earth is at the center of the universe, with the Sun, stars, and planets revolving around it.

In summary, the key difference is the position of the Earth and the Sun: in the heliocentric model, the Sun is central; in the geocentric model, Earth is central.
