On the other hand, if it is a pure pulling force, then why would the moon not be pulled towards the earth. The moon appears to be synched up with the earth, like caught in a magnetic orbit. The spin of the moon relative to the sun, is once per its monthly orbit of the earth.
This "magnetic locking" you mention is extremely interesting, and from what I've learned from looking at Simon's science, it is a much more prevalent phenomenon than we have even previously understood.
Our little "universe" here around the Sun, Earth, Moon, Mars, etc. is truly like clockwork.
If you wanted to explain this as "gravity" (a rather outmoded word associated with Newton's alchemical studies, at this point, as far as I'm concerned) then we should include what is traditionally called "anti-gravity" in the same definition. Since that merely confuses things and divides what may be a selfsame force into "attraction" and "repulsion", we might want to start with something more basic and compare gravitational effects to an electromagnetic like determiner without needing to specifically define that yet.
That is, all three effects — "buoyancy" ("anti-gravity") and "gravity" (Earthly objects, the rare celestial matter such as meteor materials being drawn to the Earth and observed parallels on nearby planets serving as our only proof of a universal gravity that is said to exist throughout the known universe) and "magnetic locking" (such as the clockwork and seemingly miraculous whole-number rhythms of the observable spheres in our Earth system) — might be read as a single kind of force: one that "works out" (without necessarily implying intelligence behind it) what is seemingly "attracted" or "repelled" from what, and in what rhythms and patterns (something like cymatics perhaps) that these things appear to be.
Anyway, I think you are onto something. Keep up your studies, aa5 and let us know if you find out more!
My personal suspicion is that we may need to get away from the idea that these phenomena are totally understood and "solved" within observable phenomena of the universe made of human senses and known particles like electrons. There may be something "underlying" (or "overlying" but in any case harder to observe) that determines what we merely discover as "gravity" and "buoyancy". This is probably why mathematical attempts to define the universe's activities have to invent things like the "graviton".
