Models in Science: Models play a central role in astronomy and science in general. Two models used extensively in this chapter are the celestial sphere and the heliocentric (Sun- centered)model for the solar system. Astronomers clearly believe that the celestial sphere model is false and the heliocentric model is true. Given this, why do you think astronomers persist in using the celestial sphere model to describe the night sky?
