I always understood the Earth-Moon system to be more similar to a double planet binary configuration gravitationaly than a Planet-Moon system (e.g. Mars, Jupiter, etc). The moon does not revolve around the earth, but rather, they both revolve around a central point. It happens that this central point under the surface of the earth due to the larger mass of the earth. Is this ever moving "center point" mystical in any way? Not really. If the lunar orbit is eliptical, then this "black moon" as they call it would be a blank vacuum, no more special than say a lagrange point.

What's the big deal?
