It is philosophically interesting because of the problems of motion and the void. Modern physics and cosmology don’t acknowledge anything besides space-time and the physics of it. Yet in order to have the Universe rotating it need be in some volume or void with something beyond its edge. The intuitive idea of a primordial empty space holding material fields that appear to be space-time seems a pragmatic inference.
One body or universe cannot be said to ‘rotate’ unless in relation to something else. Even if it were in a true void, space-time would need to be said to rotate in relation to something more than nothing. If the two-dimensional fields emanating a third dimensions entanglement scenario were located on the event horizon of a spinning black hole, as some have suggested, perhaps the math could be worked out.
Obviously there may be some other explanation for the expansion of a two-dimensional ‘bubble’ of curvature within which a true void persisted even as a third dimension of entanglement occurred. Curvature with time added may appear to be rotation from some points of view. There is also the problem of the general relativity of a virtual, contingent three dimensional Universe of entanglement engaged via mass quantum entanglement and super position naturally with a timeless two-dimensional substrate.
Interesting problems for philosophical thought- especially with the other new theory that time is a local phenomenon created by the relationship of quantum entanglement and super-position. Evidently the more quantum particles are entangled as at a black hole the more time is produced.; no time in massless two-dimensional particles and vast amounts of time in black holes- unless black holes convert all of that quantum entanglement into passages to other parts of the Universe of space-time and white holes.
