Apperently during the Apollo missions, tests were conducted after it was recorded by NASA that when the lunar landers hit the surface of the moon a 'a Bell like 'gong' was recorded and several times after as well. Does anyone know of this?

Yea I've read some theories about an alien base on the "Dark side of the moon", but I've never read about the moon being hollow which contains an alien base...
Very intruiging.

If it's not hollow, then there is definatly something very unusual about its innards, and its shell. Do you agree?

Four nuclear powered seismic stations were installed during the Apollo project to collect seismic data about the interior of the Moon. There is only residual tectonic activity due to cooling and tidal forcing, but other moonquakes have been caused by meteor impacts and artificial means, such as deliberately crashing the Lunar Module into the moon. The results have shown the Moon to have a crust 60 kilometers (37 miles) thick at the center of the near side. If this crust is uniform over the Moon, it would constitute about 10% of the Moon's volume as compared to the less than 1% on Earth. The seismic determinations of a crust and mantle on the Moon indicate a layered planet with differentiation by igneous processes. There is no evidence for an iron-rich core unless it were a small one. Seismic information has influenced theories about the formation and evolution of the Moon.

In "Moongate: Suppressed findings of The US Space Program" (1982), Nuclear Engineer and researcher/writer William L. Brian II presents evidence proving that the moon, as any hollow sphere would, "rings" when hit by asteroids or heavy space junk. And that's not all. According to Dr. Brian, "the evidence provided by Apollo seismic experiments also points to the conclusion that the moon is hollow and relatively rigid." (1)
He also reports:

"It is not commonly known that the Earth displays the same bell-like ringing or reverberations as the moon. Since the Earth is 81.56 times more massive than the moon, it takes a much larger explosion or shock wave to generate this effect.
"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. It seems hard to believe that scientists were so appalled in finding that the moon rang like a bell. After all, the Earth displays the same characteristic".
