It appears that the only method to formulate the modified Einstein’s equations, to include torque and Coriolis terms, is to utilize the U4 spacetime and not the usual four-dimensional Minkowski space, M4. This is the case because the vectors of the space in spherical topology have directionality generating a discontinuity or part in the hairs of a sphere whereas a torus topology can have its vectors curl around its short axis having no parts in the hairs so that no discontinuity of the vector space exists. Thus all the vectors of the space obey invariance conditions. Also, absolute parallelism is maintained.

Current standard theory assumes spin/rotation to be the result of an initial impulse generated in the Big Bang conserved over billions of years of evolution in a frictionless environment. Although this first theoretical approximation may have been adequate to bring us to our current advanced theoretical models, the necessity to better describe the origin and evolution of spin/rotation, in an environment now observed to have various plasma viscosity densities and high field interaction dynamics which is inconsistent with a frictionless ideal environment, may be paramount to a complete theoretical model.
