If the owls are not what they seem could it be that the Moon is not either?
After transferring the cargo of lunar samples from Intrepid, the Lunar Module was jettisoned. Intrepid was deliberately crashed into the Moon as part of a seismic experiment. The effect of the impact was recorded by the newly deployed ALSEP seismometer at the Ocean of Storms. Seismologists were surprised by what they saw. Unlike it would have done on Earth, the impact on the Moon caused it to ring like a seismic bell. The reverberating shock waves continued for 55 minutes. On the Earth the shock waves would have ceased after 2 minutes.
Furthermore, shallow moonquakes lasted a remarkably long time. Once they got going, all continued more than 10 minutes. "The moon was ringing like a bell," Neal says.
...
The moon, however, is dry, cool and mostly rigid, like a chunk of stone or iron. So moonquakes set it vibrating like a tuning fork. Even if a moonquake isn't intense, "it just keeps going and going," Neal says. And for a lunar habitat, that persistence could be more significant than a moonquake's magnitude.
It occurred at 8:09 p.m. EST, April 14. The S-IVB struck the Moon with a force equivalent to 11 1/2 tons of TNT. It hit 85 miles west northwest of the site where the Apollo 12 astronauts had set up their seismometer. Scientists on Earth said, "the Moon rang like a bell."
Now there are valid reports all over the net describing the moon resonating like a bell when struck, which some people use as proof that the moon is indeed hollow.
If NASA says the moon rings because of a rubble layer
The Spaceship Moon Theory, also known as the Vasin-Shcherbakov Theory, is a theory that claims the Earth's moon may actually be an alien spacecraft. The theory was put forth by two members of the then Soviet Academy of Sciences, Michael Vasin and Alexander Shcherbakov, in a July 1970 article entitled "Is the Moon the Creation of Alien Intelligence?".
Vasin and Shcherbakov's thesis was that the Moon is a hollowed-out planetoid created by unknown beings with technology far superior to any on Earth. Huge machines would have been used to melt rock and form large cavities within the Moon, with the resulting molten lava spewing out onto the Moon's surface. The Moon would therefore consist of a hull-like inner shell and an outer shell made from metallic rocky slag. For reasons unknown, the "Spaceship Moon" was then placed into orbit around the Earth.
Their theory relies heavily on the suggestion that large lunar craters, generally assumed to be formed from meteor impact, are generally too shallow and have flat or even convex bottoms. Small craters have a depth proportional to their diameter but larger craters are not deeper. It is theorized that small meteors are making a cup-shaped depression in the rocky surface of the moon while the larger meteors are drilling through a five mile thick rocky layer and hitting a high-tensile "hull" underneath.
Additionally the authors note that the surface material of the moon is substantially composed of different elements (chromium, titanium and zirconium) from the surface of the Earth, despite a supposed common origin. They also note that some moon rocks are older than the oldest rocks on Earth.
They postulate that the moon comprises a rocky outer layer a few miles thick covering a strong hull perhaps 20 miles thick and beneath that there is a void, possibly containing an atmosphere.
In 1975, Don Wilson published Our Mysterious Spaceship Moon in which he compiled what he considered supporting facts for this theory.
In 1976 George H Leonard published Someone else is on the Moon in which he reprinted numerous NASA photographs of the lunar surface and suggested that large scale machinery was visible in these pictures.

Try hang a solid steel ball from a chain (or use a steel plate, easier to get) and hit it. Is it hollow. Does it resonate?

NASA doesn't say that.
One theory is that the signal is scattered and repropagated in very deep rubble. An- other holds that the velocities of seismic waves from these impacts are comparable to measurements of velocities in crystalline rock. So the crystalline material which the astronauts found so abundant on the Moon's surface may extend very deep into the Moon.
I can't believe everyone hasn't heard of this theory by now, but to get the general idea out there just in case, from wikipedea:
As for the latter, he notes that the moon is the only planetary body besides Earth on which extensive seismic observations have been made. These observations have constrained the thickness of the moon's crust, mantle and core, suggesting it could not be hollow.[5]
Karen Masters of University of Portsmouth similarly suggests that, based on the behavior of objects interacting with the gravitational field of the moon, we can determine the mass of the moon. Given the observable size of the moon, we can then calculate the density, which strongly rejects the notion that the moon could be hollow.

I've always found it interesting how large our Moon is compared to Earth, which is unusual. Moons are (generally speaking) a chunk smaller than their host planet. Moons also tend to rotate around the host planet, while our Moon rotates with Earth in a tandem. In fact our "Moon" is technically not a Moon or a Satellite at all, but would be considered a duoplanet with Earth. I find it funny the name we've given the Moon is a misnomer.
If not NASA, then whose theory is it?
www.astronomynotes.com...
The Moon's density is fairly uniform throughout and is only about 3.3 times the density of water. If it has an iron core, it is less than 800 kilometers in diameter. This is a sharp contrast from planets like Mercury and the Earth that have large iron-nickel cores and overall densities more than 5 times the density of water. The Moon's mantle is made of silicate materials, like the Earth's mantle, and makes up about 90% of the Moon's volume.
You said:
~edit~ one more question... solid metal will resonate, but not ring... is describing the moon as ringing a wrong term by NASA?
What's the difference between ring and resonate?

as far as we're concerned (ie what we can see of it from earth) it doesn't. one side is always out of our sight.

There's plenty to learn about the Moon...and Mars...and Venus...and Earth for that matter.
You don't think the Moon is a mothership, do you?
