Even if one advocates the breaking down of any torus which is moving/rotating relative to a stationary observer, he must explain why it breaks. And to explain the asymmetry created with this breakdown. Which internal/external forces caused it?
Why wouldn't that also apply to my rope example?
Each piece of the ring is longer as measured by an inertial observer comoving
We, at this problem, don't care for a "comoving" inertial observer. We care for the stationary observer in the center, who first see stationary and then rotating torus, which should contract. But only in the direction of moving.
As per a recent comment this thread is meant to voice contrarian opinions, that is anything this community tends not to agree with. Thus I ask you to post your contrarian views and upvote anything you do not agree with based on personal beliefs. Spam and trolling still needs to be downvoted.
