Hello! I am kinda confused in a thought experiment that my teacher gave me for thinking about. It is about circular motion. The question is that if you spin a rod and the point A, close to the center, is moving with a speed which is approaching to 'c', then what happens to the rest of the rod, which is further than point A from the center. I mean, the rest of rod should move even faster, but it would require a speed which would exceed the light barrier, but it would be a violation of STR or ...?
