Hollow Moon

degrassinoel

was watching a documentary on the history channel just now, ancient aliens (i think)

the last 20 minutes or so were quite entertaining, this was from the apollo13 mission.
The 15-ton spent third stage of the Saturn V launch vehicle crashed into the Moon, as planned.

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."

So the theory is that the moon could be hollow or at least partially hollow, possibly a surveilance craft (lol cant swallow that part sorry).
But its quite interesting, as apparently the earth is partially hollow too.
according to seismologists who recorded an alaskan earthquake

"Joseph Goodavage referenced such occurrences in his book, "Astrology: The Space Age Science". He mentioned that the ringing effect was recorded during the May 22, 1960 Chilean earthquake. This was supposedly the most violent earthquake that had been recorded since the establishment of official world records in 1881.
Goodavage provided a description of the effect which was given at the 1961 World Earthquake Conference, held at Helsinki, Finland.

The description stated that the shock was so severe that the "entire planet rang like a bell". The ringing continued for a considerable length of time in a regular series of slow impulses which were recorded at various independent seismic stations. Goodavage also noted that the planet rang again as a result of the Anchorage, Alaska earthquake of March 27, 1964.

happy reading

plus some at http://en.wikipedia.org/wiki/Hollow_Moon - though it follows the course that theres a lot of scientific evidence to proof the moon is quite solid.

Hollow Moon proponents would, however, have to account for the incredible density of the Moon's crust if it were in fact hollow. As gravitational pull is determined by mass, a hollow moon would require an inordinately dense crust to achieve observed gravitational values.

yeah, its the ringing like a bell part that has me puzzled

I think either Paranormal magazine or Fortean Times did an article on Cryptoterrestrials a while back, saying that a hollow moon could be a base for them. Entertaining reading, but that's mostly it. I can't see any evidence that'd convince me.

If it interests anyone, Arthur C. Clarke used the theory (kinda) in The Last Theorem, where humans lived in altered lava tubes in the Moon. Again, fun.

And that's all I have to say about it

The sun "rings like a bell" too. See here.

The Sun "rings" like a bell---which lets GONG probe its deepest secrets.

Sound waves bouncing through the Sun.

The trick is to study the Sun by analyzing the sound waves traveling through it, explains John Leibacher, an astronomer at the National Optical Astronomy Observatories in Tucson, Ariz., and director of the NSF-funded Global Oscillation Network Group (GONG). Much as the waves produced by earthquakes and explosions roll through the Earth, he says, these solar sound waves pass through the Sun's gaseous mass and set its surface pulsating like a drumhead. With six telescopes set up around the Earth collecting data every minute, GONG scientists can measure these pulsations, and thus learn about the Sun's structure, dynamics and magnetic field.

Of course, they don't mean it's hollow.

Could it be related to the moon's lack of a liquid core? I recall seeing a documentary a few months ago which said that moonquakes (the moon equivelant of earth quakes) are much stronger than they would be on earth because the earth's liquid core acts as a dampner or shock absorber. Being completely solid, the moon would transmit vibrations much better than earth, that seems to fit with the OP.

maybe it was a bad analogy on nasa's part, sounds really odd though
