The earliest astronomers observed the Sun's daily motion across the sky. Until the early 1500s, astronomers believed the Sun's apparent motion was evidence that

• the Earth was at the center of the universe

• the Sun was at the center of the universe

• the stars were fixed in the sky

• the planets moved in perfect circles

The Sun revolved around Earth. Today, the Sun still moves across the sky every day, but astronomers no longer believe that it revolves around Earth. Why has the theory explaining the Sun's motion changed, while the observation of the Sun's motion has remained the same?

• New technology has shown that the human eye cannot adequately observe the Sun's motion across the sky.

• New technology and research has allowed scientists to reevaluate the conclusions drawn from the original observation.

• Scientists have developed new theories that do not require evidence derived from observations.

• Scientists have made new observations that make it possible to ignore the original observation.
