why would anyone believe NASA is telling any truth at all??
What i mean is..there are people and a few who are ex-workers claiming nasa is a computer generating imaging station faking pictures of our entire universe,planets, solar systems,blackholes etc,
And there are many physics scientists finding more and more answers that support the argument we are living in a simulation. So it would make sense to come to the conclusion,based on a lot of support, that the OP may in fact, be onto something.

How did it "ring" in the absence of an atmosphere for the sound to travel? I am pretty sure it rung seismically and was picked up with seismic sensors.

If its vibrating it means there is a standing wave set up with nodes and antinodes. If the vibration frequency is known, and and moon is solid made of the material on the surface you will be able to calculate the vibration frequency. The amplitude of the wave is dependant on how hard its the moon is hit. The calculated value of frequency should be accurately predictable for a the moon solid full density, half density and tenth density hollow. The calculation shouldn't be that hard if you know the volume of moon, its the cubit density of the material its composed of, attenuation factor for that material. If the calcs are done and you compare it to the actual frequency measured, what ever that was?????
you will see if which end of scale it sits at a solid or hollow.

Not correct. Yes the earth vibrates with earthquakes, but they determined that the moon must be hollow or a lot less dense by the INTERPRETATION of the data. Anything solid will vibrate. The point is the moon vibrated like it would if it was hollow or not very dense.
On Earth, vibrations from quakes usually die away in only half a minute. The reason has to do with chemical weathering, Neal explains: "Water weakens stone, expanding the structure of different minerals. When energy propagates across such a compressible structure, it acts like a foam sponge--it deadens the vibrations." Even the biggest earthquakes stop shaking in less than 2 minutes.
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.

The craters are impact craters not the result of natural formation under effects of gravity and erosion. .

I wonder whats Buzz reaction would be if he was asked the question "is the moon hollow"
