Question
Greek astronomers used all of the following ideas or observations as reasons to reject Aristarchus's idea that the Earth rotates and moves around the Sun, except for one. Which one did they NOT use to reject a moving Earth?
A. They deduced that the Sun is larger than the Earth.
B. They observed no stellar parallax.
C. It was in conflict with Aristotle's theory on the natural places of the four elements (earth, air, water, and fire).
D. They observed no change in the angular separation between stars during the year.
Explanation / Answer
It should be D logically. Because there is change in angular position of stars during the year. Which signifies earth is moving. So this point can't be used to prove Aristarchus idea of rotating Earth.
