- TL;DR Summary
- What happens to distance?

Simple as it sounds!

Usually people derive aberration of light using linear motion, not circular motion. When aberration happens in linear motion, one would expect distance between the source and the observer to change. But, in circular motion, the path light takes in the circular motion, in the source frame of reference is ##r##.

Thus, I would expect distance in the frame of reference of the moving object to be ##r## as well!

The motion is perpendicular to ##r##, speed of light is fixed, yet we have time dilation! therefore traveled distance is elongated!

What am I missing? Does distance change?
