SUMMARY

The discussion focuses on the concept of relativity in physics, emphasizing the time it takes for star A to travel from position A1 to position A2. This highlights the fundamental principles of Einstein's theory of relativity, which asserts that time and space are interwoven and that the speed of light is a constant. The conversation underscores the importance of understanding these concepts for grasping advanced astrophysical phenomena.

Homework Statement: The Principle of the astronomical measurements which indicate that the velocity of light is NOT constant relative to its source can be demonstrated by the following problem. Consider a pair of stars A,B of equal mass in circular orbit about their center of mass, C which is a distance d from earth. Assume that the orbit radius is r , the orbital velocity u and that the line of sight to earth is in the plane of orbit.
I understand where the 2nd term in part II comes from but where does πr/u come from ?
