I postulate there is a center in our universe and it is a super massive black hole white hole complex and our universe is rotating just as our galaxy rotates this explains the flat appearance of our universe we are in a giant accretion disk propelled by the propellant force of the initial white hole that spawned our universe into existence.eventually our universe will stabilize as the electromagnetic field of our central black hole reaches equilibrium at that point our universe will rotate around it's central black hole. This side of our dualiverse is most likely still in the white hole phase this explains the erratic and unpredictable motions of the galaxies as in dark flow and galactic collisions . If our universe was in the black hole state then the motions of the galaxies would be predictable and uniform just as the solar systems and stars are within the galactic arms of our own galaxy. So the galaxies would be held in place by the gravitational force exhibited by our universe black holes magnetic spiral arms. The galaxies in our universe universe show no sign of the rigid and steady motion generated by a black holes magnetic field lines . So in conclusion our universe has a center that center is currently a white hole eventually that white hole will collapse and become a black hole our universe will rotate steadily and uniformly until the black hole at the center collapses and our universe will be pulled into it and this process will be repeated at universe bs white hole exit.
