What can I say? I really kinda like you as you give a pretty hard and respectable debate. But I like to let the facts do the talking for me. The moon
reverbating? You wouldn't beleive it, but the sound resonated throughout the moon for over 2 hours? That's astounding to me. A bell doesn't even
vibrate that long! This has happened a few times. Also, the moon is much older than the Earth. By 1 billion years and the moon is of a different
compund than the Earth rock. Read up on the facts. If you care to learn, you WILL find it as I have presented this information. I never stated that
the moon made a sound either. I simply said it vibrated, resonated or reverbated. You jumped the gun and misinterpreted it as sound. Am I correct?

Regarding the age of the Earth versus the Moon, the U.S. Geological Survey has studied this, and I'll post a portion of my findings as I posted
earlier in this thread:
An interesting feature of these ancient rocks is that they are not from any sort of "primordial crust" but are lava flows and sediments
deposited in shallow water, an indication that Earth history began well before these rocks were deposited. In Western Australia, single zircon
crystals found in younger sedimentary rocks have radiometric ages of as much as 4.3 billion years, making these tiny crystals the oldest materials to
be found on Earth so far. The source rocks for these zircon crystals have not yet been found. The ages measured for Earth's oldest rocks and oldest
crystals show that the Earth is at least 4.3 billion years in age but do not reveal the exact age of Earth's formation.
The Moon is a more primitive planet than Earth because it has not been disturbed by plate tectonics; thus, some of its more ancient rocks are more
plentiful. Only a small number of rocks were returned to Earth by the six Apollo and three Luna missions. These rocks vary greatly in age, a
reflection of their different ages of formation and their subsequent histories. The oldest dated moon rocks, however, have ages between 4.4 and 4.5
billion years and provide a minimum age for the formation of our nearest planetary neighbor.
This states, in essence that it is easier to get a solid date on the formation of the moon due to its lack of plate movements, weather, etc. It's
pretty solid fact that the moon is aged roughly 4.4 and 4.5 billion years.
The Earth, on the other hand, with its constantly changing surface is far more difficult to date. The above article states that the oldest known
mineral formations found on Earth are the zircon crystals found in Western Austrailia, dating back 4.3 billion years. However, crystals such as these
do not form out of the blue. Formation of crystals such as these take thousands (or perhaps millions) of years. Knowing this, one can surmise that
the Earth is far older than these crystals. The minimum age for the Earth is 4.3 billion years, but the evidence inherent in these cystals suggests
that it is far older than that.
At the most, the age discrepancy between the Earth and the Moon is only a million years or so, and that's still open for debate.
The physical makeup of the Moon is significantly different from the Earth. That is known fact. There are still theories outstanding as to how it was
formed and how it came into Earth orbit. These theories include being "caught" in Earth's gravitational field, forming from debris left over from
the "big bang", though a seperate debris field from the one our own planet was formed from, etc. I feel the most viable explanation for the
formation of the moon, which would also sort of support your "hollow moon" theory, is that it was formed, over time, as various particles and debris
(likely from the asteroid belt) collected together. It seems far more likely that the Earth's gravitational field caught a smaller asteroid, which
then started an orbit around the earth. Other asteroids may have followed from the same disturbance that followed the first one out, and eventually
started to amass around the first asteroid in our orbit. Over time, enough would have collected to form the moon as we know it. As a result of this
type of formation, the moon would also remain very porus, with many caves running throughout it. Not necessarily with a large open space in the
middle, but more along the lines of a sponge. The acoustic properties of an object such as this would actually allow for a prolonged reverberation of
a severe impact. There's also far less believable theories for the moon's formation. One being the "moon is a spaceship here to watch us"
theory. Another being the "Planet X / Nibiru" theory (the moon was caused by a collision between Earth and Nibiru, formed from the resulting
planetary debris from both planets. Earth settled back into a sphere, the water fiilling the low points, and Panagea was the resulting land mass.
Over time, Panagea split, and moved to the positions we're familliar with for the continents now.
However, with all of these theories, there really is no factual information nor compelling evidence to support any of them wholly. Consequentially,
all of these theories are simply speculation, and none should be trusted fully. Given that all we know currently is that the Earth and Moon are
roughly the same age, and that the Moon orbits our planet as it does, we do have a far side of the Moon which is never visible from Earth. There have
been a few anomalies detected on the moon, but none that can either be fully proven or disproven. We can all speculate on our own theories, or
existing ones, and perhaps we can find the one that makes the most logical sense. However, whatever theories are brought up, we'll have to expect
that they will be looked at and individual parts of theories (and sometimes whole theories themselves) are going to be either proven possible, or
proven impossible. Given the results of this discussion, we can most likely finally form an opinion of possibility.
Of course, the hard fact is, we'll never know unless someday we're able to travel back in time to the creation of the Earth and Moon, and finally
witness for ourselves what actually happened.
