Apart from general relativity and purely from the special relativistic point of view, rotating hemisphere pauses a great mechanical problem in physics, because of its apparent breaking of Newton's second law of motion. Ie, the movement of an object which is a measure of the displacement of its center of mass happens without the corresponding external force in the direction of the displacement.
Of course, this empirical observation was the original cause of the beginning of the quest in this field. If Newton's second law can be broken, it means that the energy conservation law in a local mechanical system can no longer be an absolute physical law.
The paper published in the llnl.gov archive on the title is a result of this research.
