Has anyone heard of the Hollow moon theory?

My apologies if the below already has been related to, if not, well, enjoy.

From the two articles linked to at the end of this post, the following quotes and more can be extrapolated (I'll skip the acoustic echo 'bell'-thread since you've already touched upon this...):

1: The first academic enigma must surely be that the Moon is apparently in its wrong orbit for its size. However, this would presumably be based on its assumed density. Technical reports claim a density of 3.3 for the Moon compared with 5.5 for Earth. Astronomy data indicates that the internal regions of the Moon are less dense than the outer, giving rise to the inevitable but outrageous speculation that it could be hollow. The eminent scientist Carl Sagan, a typical sceptic, made the statement, 'A natural satellite cannot be a hollow object'. But meaning here that if it is hollow, it is not a natural satellite---and therefore artificial.

2: It has been found that asteroids and meteors not only create shallow craters on the Moon's surface but produce a convex floor to the crater instead of concave as expected, supporting the idea of a rigid shell.

3: 'Spaceship Moon' is the brainchild of the two Soviet researchers but many others agree with the theory, including NASA scientists at JPL and an Oxford University physicist. The capture theory is now back in favour but with a significant adjustment that the Moon was steered into orbit.

4: (concurring with #1 above...) Evidence for the moon being hollow comes from a variety of experts and in some cases predates the lunar landings. In 1962, Dr. Gordon MacDonald, one of NASAs own scientists reviewed data relating to the density of the Earth, which calculated that the moon’s mean density was 3.34 gm/cm3 (3.34 times an equal volume of water), in comparison the Earth’s density is 5.5 gm/cm3. This led him to observe, "If the astronomical data are reduced, it is found that the data requires that the interior of the moon is more like a hollow than a homogeneous sphere."

5. The Nobel award winning chemist Dr. Harold Urey, has also suggested that the moon contains a ‘cavity’ and MIT’s Dr. Sean C. Solomon is on record as saying, "the Lunar Orbiter experiments vastly improved our knowledge of the moon’s gravitational field . . . indicating the frightening possibility that the moon might be hollow."

And if nothing else, my personal favourite proving our friendly neighbours possible hollow inside;

6. Texts from as far a field as Europe and South America speak of ancient people who lived on Earth before the Earth had a moon. In Greece they were called Proselene, meaning ‘before the moon’. Apparently, in South America, symbols found on the wall of the Courtyard of Kalasasaya, near the city of Tiahuanaco (in Bolivia), record that the moon first appeared around 12,000 years ago. The appearance of the moon was said to have caused great disruption to the Earth in the form of earthquakes, massive flooding and climate changes. Interestingly, this remote site has been suggested by some scholars as being the actual location of Plato’s legendary Atlantis and this great planetary upheaval as being the cataclysmic event that destroyed Atlantis.

7. Isaac Asimov once commented that: “There is no astronomical reason why the moon and the sun should fit so well. It is the sheerest of coincidences, and only the Earth among all the planets is blessed in this fashion.” This "coincidence" means that the moon is just the right size and distance, to completely block the sun during an eclipse. Eclipses are infrequent events but are often linked to quite serious earthquakes. Was the moon placed in a very specific orbit by a higher intelligence from another world who wanted to either monitor us as a species or exert an element of control over our planet?

Ringing would just be a question of harmonics--and the moon was a new study for NASA. Simple logic shows that the moon has a calculable mass and can be dated. The mass is evident in our tides and can be calculated closely, hence the moon isn't hollow. A hollow moon would have been a monster to create and would have such bizarre seismic instabilities as to be undoable.

And who would have technology to "make" a hollow moon? Any beings with such a capacity would have no need for a hollow moon. They could hide wherever they want by bending light around themselves. Even the grays can do that, and they can't do a hollow moon. So, there's no reason, no logic, and no need for a hollow moon. Creation of such would be a monstrous energy drain. If any aliens wanted a moon here, they would simply have dragged one here using "electrogravity" focused upon and pulling through a larger body.

So the hollow moon story isn't a theory. Theories have good, demonstrable evidence to support them. Hollow moon is just wild speculation based on a new kind of seismic resonance, nothing more.

the evidence is apparently not disputed, so all that varies is interpretation... so let's just say

if the loss of sound enerhy is small you're probably dealing with something very rigid and homogenous, spanning the entire object...

This is from my new favorite website:

begin quote [A theory that suggests that the moon is a large hollow sphere. Backed up by little evidence, but still regarded by some as a possibility, the hollow moon theory originated during seismological tests on the moon following the Lunar landings. This occurred most notably in November, 1969, after seismometers were set up on the moon's surface by the astronauts of Apollo 12. When the Lunar module had taken off, heading back to earth the astronauts discarded the ascent stage of the lunar module, dropping it on the moon's surface, smashing the craft and creating a tremor that was picked up by the seismometers. When the NASA scientists heard the data stream, they couldn't believe what they were hearing. The moon was ringing like a bell and continued to do so for around an hour. After they had had a chance to analyze the seismological information, NASA declared that the moon seemed to be a hollow sphere with a metallic layer around 34-40 meters deep.] end quote

I guess this has been discussed to death...last post was in 2006!

Apollo 13 had a mission project to explode a plutonium bomb on the moon to test for resonance sound, and it was reportedly disabled before it could be launched. Odd in 2009... we are still trying to explode things on the moon.
