The Southern Celestial Rotation refers to the anti-rotation of the stars observed in the southern regions of the earth.
Under the Monopole model P-Brane explains the counter-rotation of the stars as a consequence of perspective. The author uses the sun's crepuscular rays as an example for how motion and perspective can seem to cause anti-rotations in two different directions, much like how spinning in the chair and looking up and down can cause the appearance of two rotations in different directions.
According to P-Brane's explanation the observer is seeing a wide range of stars squished into a small area by perspective. Rotation opposite from the Northern rotation appears as a mirrored anti-rotation due to opposite converging perspective elements.
Q. How can two people on opposite sides of the earth both see the same South Pole Stars simultaneously?
A. Since those areas are many hours apart from each other, when it is night or dusk for one area it is likely day or dawn for the other. It is questioned whether it is the case that those observers see the same stars simultaneously. Due to the time difference it may be that they see the stars alternately.
Under the Bi-Polar Model the rotation in the south is explained with the existence of a South Pole and a rotating southern celestial system above it.
