Apparently people forget that a tuning fork is not hollow.
But is it uncharacteristic for a solid sphere as big as the Moon, made of the same material?

Sorry, I don't understand what you mean by that or why you wrote it.
Maybe when the bible was written, a bell was the closest object to compare it to...
We may think of the Earth as a solid sphere, but in fact the solid crust is only a few km thick under which there is essentially liquid rock or magma.

That's great work OP!
You know what's really doing it in for NASA? The fact that they want Gary McKinnon so badly.

In fact the upper mantle is more solid than that. It behaves like an extremely viscous liquid (as does glass) but is mostly "solid". It is molten where there are volcanoes because there is a magma chamber there beneath the crust which has risen from deeper within the Earth.

That's true.

S waves can only travel through solids, and not through liquids. So of course when the solid part of the moon extends to probably 72% of its depth (source: www.nasa.gov...), while the solid part of the Earth's crust extends to perhaps 1% of it's depth, of course the S-wave propagation characteristics should be completely different on the moon compared to the Earth, as a result of this dramatic difference.
This may have something to do with the moon "ringing" longer than the Earth; it's more solid than the Earth, which contains proportionally more "liquid rock" than the moon. And if you ever look at lava flowing out of a volcano, the molten lava just doesn't look like it would be a very good conductor of sound, meaning if you hit the lava with a sledgehammer, you wouldn't expect to hear as much ringing as you would if you hit a solid rock instead.

However it still doesn't exactly refute my point that you have to go much deeper in the moon to find a comparable extremely viscous liquid, and that the acoustic properties of the moon will be expected to differ significantly as a result. I did oversimplify a bit for brevity and I consider your correction/clarification to be quite valid.
Yes, but as we have only seismic data from Earth and a little from the Moon, the only thing we can be sure is that they are different.

Any vibration lasting that long is in a solid sphere is uncharacteristic of what we see here on earth.
What I don't understand is the Bible connection.
Tuning forks weren't around when the bible was written so just thought I'd say maybe a bell was the closest thing they could use to explain a phenomenon. You can only explain stuff as good as what you know.
At last. That's how far I got but no further. I'm not the only one who hasn't grasped the rest of the "explanation".

No evidence of WHAT?
The only "evidence" I provided in this thread was photos that prove the astronaut was holding a camera, thus why the OP was incorrect in his evaluation of that aspect (that the reflection was a cutout). I did that packaged in as an example of how to be effectively skeptical as opposed to your approach (which is "utilized" by a great number of people here).
Are you sure it's I who is seeing what they want to see?
