Maybe that is why we havent been back, and the rest of hte misssions were :Faked"?
A bell rings because it has an opening at, at least one end. Then if the moon rang like a bell, then does it too, have an opening somewhere?

I don't think actual "ringing" was meant to be implied. Its sounds as if they meant there was a reverberation (like that of a ringing bell) which would happen even with a completely enclosed structure.
Makes sense about why we haven't been back. Too many missions would make information like that public. What would that do to the "approved" thought patterns? If the moon really were hollow, then that would imply that other bodies could be hollow as well.

(I'm not saying it means its hollow either, but we can't PROVE one or the other).

I kind of think that we can. Certainly there is ample evidence that the Earth is not hollow.
The hollow moon theory has never been seriously accepted by anyone. There have been numerous theories on the origin of the moon, but the latest (the big splat) manages to tie in all of the loose ends, the lunar motion, the orbit, the lunar mass, and most importantly, the composition of the lunar rocks retieved by the Apollo missions.
For 60 years geophysicists have suspected that the Earth's inner core was solid - now they have proved it.
By detecting special seismic tremors in the aftermath of a massive Indonesian earthquake, the seismologists from Northwestern University and the French Atomic Energy Commission have shown without doubt that at the heart of the Earth is a solid iron-nickel ball, 2400km in diameter.
The key to the breakthrough is the behaviour of the two types of seismic waves. Pulse waves can travel through both liquids and solids as they move by compressing and then relaxing the material in the direction of travel.
Shear waves, in contrast, can only pass through solids. They vibrate at right angles to the direction of travel and as liquids have no material strength the signal rapidly dissipates in the fluid.
So they then had to exploit the different speeds at which the waves travel. Imagine a seismic wave rumbling down through the Earth. When it reaches the outer core, all shear waves are lost and only pulse waves continue. When the pulse waves reach the inner core the waves are partly refracted and reflected.
This allows part of the energy to convert into shear waves that then travel through the inner core. Shear waves travel more slowly than pulse waves so they reach the opposite side of the inner core later. Here they are partly converted back to pulse waves.
It was these delayed pulse waves that the scientists detected.

The Earth has a solid Iron core; we know this by detecting earthquake vibrations and their travel through the earth.

This is all just theory. The findings you quoted are assumptions made based on existing theories.

I have provided enough proof for a reasonable person to see that the earth and moon are not hollow. It isn't theory it's scientific proof. You may continue to believe whatever you wish.
