Universe in a rotating black hole and preferred axis

Abstract

If our universe was born as a baby universe on the other side of the event horizon of a black hole existing in a parent universe, then the corresponding white hole at rest provides the absolute frame of reference in the universe. In this frame, the cosmic microwave background radiation is isotropic on large scales. If the parent black hole is rotating, then its axis of rotation becomes a preferred axis in the universe. Accordingly, the absolute frame is non-inertial, although the non-inertial forces are small. To decrease their energies, galaxies tend to align their axes of rotation with the preferred axis, resulting in clockwise-counterclockwise asymmetry. The centrifugal force causes a large-scale bulk flow of galaxy clusters in directions perpendicular to the preferred axis. The astronomical data seem to support these motions. The angular velocity of the universe decreases as the universe expands, which is a consequence of the conservation of the angular momentum of the universe. The centrifugal force in a rotating universe, which also decreases, may be the origin of dark energy, in accordance with recent DES observations showing that dark energy becomes weaker with time.
