I understand that massive spinning objects drag spacetime along with their rotation, and that the inner region is dragged more strongly than the distant regions. It would seem that spacetime gets stretched. Does spacetime have an elastic limit, such that it could "break" at some point? Or is it infinitely elastic? Could a sufficiently massive object, perhaps one that is configured like a propeller, cause something akin to cavitation of spacetime if it were to rotate sufficiently fast?
