I saw the following question in the Physics-SE, and thought it is interesting.(adsbygoogle = window.adsbygoogle || []).push({});

"In the special relativity it is well established that, in the vacuum no one can ever travel faster than light, due to the relativistic velocity addition formula. However, it is legitimated to ask whether the no-faster-than-light derived from the translational speed addition could be extended, or be equivalent to, the no-faster-than-light for the rotational speed as well. I had the hunch that, there should be a proof to show the equivalency between the two. How to prove, or disprove (unlikely though), this equivalency?"

Anyone, any ideas?

Thanks,
