Let's say I can see a star in a distance of 1ly in front of me.
I'm sitting on an office chair and begin to rotate with a speed of 1/s (1 rotation per second).
Then I consider me as not rotating and everything else as rotating.
Now I will see the star traveling a circular path with the incredible length of 2*pi*1ly in 1 second.
What is wrong about saying the star is traveling with a speed of 2*pi*ly/s ≈ 2*10^8*c?
