Your former state of ignorance...

No, it may very well stay a present state of ignorance for quite some time. I've put more stock into electromagnetics than gravitational theory for a number of years now. The more I read about it, the more sense it makes to me.

The gravity pitch makes no sense to me. The swinging weight of a molten moon core would either have sent the moon flinging off into space or would have sent it crashing to earth.

No matter, it's the wrong thread for this. Later WildTurkey.

This from the person that said that a "moon" always presenting one face to its parent was highly improbable. You are definitely a "deep thinker".

The swinging weight of a molten moon core would either have sent the moon flinging off into space or would have sent it crashing to earth.

Now this is where you begin to stumble.  I found a site written for pre-teens (so it should be right up your alley) that covers this topic:

We know that the Moon has a very weak magnetic field. Oddly enough, this is fairly strong evidence that it does not have a molten core. Rotating planets or moons with molten cores will produce magnetic fields through "the dynamo effect." In a planet like the Earth, the molten core can flow freely in a process called convection. In addition, the Earth rotates, adding to the movement of the molten core. The flowing molten iron-nickel material can produce electrical current, which, in turn produces a magnetic field that surrounds the Earth. If the Moons core were molten , then it would have a field too, though it would be weaker. We only a detect a very weak field, much weaker than that expected from the dynamo effect.

Since small "moonquakes" have been measured, which probably originate in the core of the Moon, it could be partially molten. But for the reason described above, it can not be totally molten.

Much of the information in this reply can be found in Michael Seeds' _Foundations of Astronomy_, and probably several other astronomy and geology books.

I went ahead and highlighted the information for you so you don't have to struggle with all the big words.
