For over an hour. It’s hollow, possibly a space ship

Also

A moon that's in the right orbital plane, of the right size, and at the right distance to cause a total solar eclipse has to be among the rarest of arrangements anywhere in space. Most moons are too large and/or close (they would still cause am eclipse but would block out the sun complete, so no corona - just a dark sky). The fact that our moon does this is almost nfinitely unlikely but it happens.

Why do they never talk about this anymore

The Moon rang like a bell

Between 1969 and 1977, seismometers installed on the Moon by the Apollo missions recorded moonquakes. The Moon was described as "ringing like a bell" during some of those quakes, specifically the shallow ones.[11] This phrase was brought to popular attention in March 1970[1] in an article in Popular Science.[12]

On November 20, 1969, Apollo 12 deliberately crashed the Ascent Stage of its Lunar Module onto the Moon's surface; NASA reported that the Moon rang 'like a bell' for almost an hour, leading to arguments that it must be hollow like a bell.[1] Lunar seismology experiments since then have shown that the lunar body has shallow moonquakes that act differently from quakes on Earth, due to differences in texture, type and density of the planetary strata, but there is no evidence of any large empty space inside the body.[11]

Vasin-Shcherbakov "spaceship" conjecture

Speculative cutaway model of a Spaceship Moon

In 1970, Michael Vasin and Alexander Shcherbakov, of the Soviet Academy of Sciences, advanced a hypothesis that the Moon is a spaceship created by unknown beings.[2] The article was entitled "Is the Moon the Creation of Alien Intelligence?" and was published in Sputnik, the Soviet equivalent of Reader's Digest.[1][13] The Vasin-Shcerbakov hypothesis was reported in the West that same year.[14]

The authors reference earlier speculation by astrophysicist Iosif Shklovsky, who suggested that the Martian moon Phobos was an artificial satellite and hollow; this has since been shown not to be the case.[15] Skeptical author Jason Colavito points out that all of their evidence is circumstantial, and that, in the 1960s, the atheistic Soviet Union promoted the ancient astronaut concept in an attempt to undermine the West's faith in religion.[2]

"Perfect" solar eclipses

In 1965, author Isaac Asimov observed: "What makes a total eclipse so remarkable is the sheer astronomical accident that the Moon fits so snugly over the Sun. The Moon is just large enough to cover the Sun completely (at times) so that a temporary night falls and the stars spring out. [...] The Sun's greater distance makes up for its greater size and the result is that the Moon and the Sun appear to be equal in size. [...] There is no astronomical reason why Moon and Sun should fit so well. It is the sheerest of coincidence, and only the Earth among all the planets is blessed in this fashion."[16]

Since the 1970s, conspiracy theorists have cited Asimov's observations on solar eclipses as evidence of the Moon's artificiality.[17][18] Mainstream astronomers reject this interpretation. They note that the angular diameters of Sun and Moon vary by several percent over time and do not actually "perfectly" match during eclipses.[19] Nor is Earth the only planet with such a satellite: Saturn's moon Prometheus has roughly the same angular diameter as the Sun when viewed from Saturn.[19]

Some scholars have claimed that "the conditions required for perfect solar eclipses are the same conditions generally acknowledged to be necessary for intelligent life to emerge"; If so, the Moon's size and orbit might be best explained by the weak anthropic principle.[19][20][21]

Ha, see it all makes sense.

Abstract

Unusually long reverberations were recorded from two lunar impacts by a seismic station installed on the lunar surface by the Apollo 12 astronauts. Seismic data from these impacts suggest that the lunar mare in the region of the Apollo 12 landing site consists of material with very low seismic velocities near the surface, with velocity increasing with depth to 5 to 6 kilometers per second (for compressional waves) at a depth of 20 kilometers. Absorption of seismic waves in this structure is extremely low relative to typical continental crustal materials on earth. It is unlikely that a major boundary similar to the crustmantle interface on earth exists in the outer 20 kilometers of the moon. A combination of dispersion and scattering of surface waves probably explains the lunar seismic reverberation. Scattering of these waves implies the presence of heterogeneity within the outer zone of the mare on a scale of from several hundred meters (or less) to several kilometers. Seismic signals from 160 events of natural origin have been recorded during the first 7 months of operation of the Apollo 12 seismic station. At least 26 of the natural events are small moonquakes. Many of the natural events are thought to be meteoroid impacts.

But something interesting happened on Apollo 12. After Pete Conrad and Al Bean landed at the Ocean of Storms on November 14, 1969, they left the lunar surface 142 hours into the flight. Eight hours later, they were reunited with Dick Gordon in the command module and sent their spent lunar module back to the Moon. It impacted about 40 miles away from the Apollo 12 landing site with the force of one ton of TNT. The resulting shockwave built up and peaked in just eight minutes. Then it took an hour to fully dissipate.

Something similar happened on Apollo 13. The S-IVB impacted the Moon 85 miles from Apollo 12’s ALSEP — CMP Jack Swigert joked at the time that it was the only thing on that mission to go right. It hit with the force of 11 and a half tons of TNT. This translated to a seismic impact peaked after seven minute with shockwaves 30 times greater and four times longer than those from Apollo 12’s LM impact.

The vibrations from these two impacts lasted longer than scientists expected, far longer than any equivalent vibrations last on Earth. It was almost as if the Moon was ringing like a bell. This strange result forced scientists to think differently about the Moon and its composition.
