Faster than the moon rotates? Is it fluid dynamics in tides? If so I think that the Earth would rotate in sync with the moon. One day would last thirty days or maybe even less. The moon has its orbit but does it technically even rotate relative to the sun? One side is always facing it. But the moon appears and does rotate to us. The moon does not always show us the side of the mans face. If we had a telescope on the sun it would always appear to be full. If the moon did not aid the spin then its tidal forces would make the Earth slow down. Still it is not the constant force that keeps the Earth spinning in this system. Is it possible that the moon acts like a mirror to some forces that cause the earth to spin?
