Wie erklärst du den frame-dragging effekt mit einer rein statischen ganzzahlig dimensionalen Raumzeit?
Zitat:

Frame-dragging is an effect on spacetime, predicted by Albert Einstein's general theory of relativity, that is due to non-static stationary distributions of mass–energy. A stationary field is one that is in a steady state, but the masses causing that field may be non-static??—?rotating, for instance. More generally, the subject that deals with the effects caused by mass–energy currents is known as gravitoelectromagnetism, which is analogous to the magnetism of classical electromagnetism.

Was ist mit Gravitationslinsen? Wie können die denn entstehen in einem statischen 3D-Raum bzw. in einer statischen 4D-Raumzeit?
