Question

Scientific models are representations of objects, systems or events, and are used as tools for understanding the natural world. However, models also have limitations. Which of the following statements describes one limitation of the geocentric and heliocentric models of our Solar System?

Both models represent multiple stars within our Solar System.
Both models include the Sun.
Both models include a central celestial body with other celestial bodies revolving around it.
Both models include the Earth with one revolving moon.

Answer 1

The limitation common to both the geocentric and heliocentric models is the incorrect representation of multiple stars within our Solar System, which only contains one star, the Sun.

Step-by-step explanation:

A limitation of both the geocentric and heliocentric models of our Solar System is that they contain fundamental inaccuracies when describing the true nature of the cosmos. The geocentric model, which places Earth at the center, was historically accepted but required increasingly complex additions of circular paths or 'epicycles' to describe celestial motions. On the other hand, the heliocentric model, which positions the Sun at the center, aligns better with the modern understanding of gravity and planetary motion as explained by laws of physics, including Newton's law of gravitation.

However, the statement that represents one limitation of both models would be that 'Both models represent multiple stars within our Solar System.' This statement reflects a common misunderstanding, as our Solar System contains only one star, the Sun, and any representation suggesting multiple stars would be incorrect. Such a limitation demonstrates the challenges that arise from trying to accurately model complex celestial phenomena.
