Is the Moon Hollow?

[Krsps]

Is the moon hollow? It is said it rings like a bell. Was it brought here? Is it an artificial space station brought to Earth to stabilize the atmosphere and make our planet habitable?  Is it filled, on the inside with offices of alien engineers and scientists?

It's is said that the Earth would wobble too much if the moon was not there to stabilize the gravity.

What do you think?

There's also a lot more evidence or pros and cons on this argument on the line if you're looking

You didn't finish the quoted paragraph. Here it is.

When Apollo 12 deliberately crashed the Ascent Stage of its Lunar Module onto the Moon's surface, it was claimed that the Moon rang like a bell for 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.

"Rang like a bell" is a figure of speech. The acoustics of sound propagation do not require a hollow cavity for something to ring like a bell.

There's also a lot more evidence or pros and cons on this argument on the line if you're looking

There is no evidence for this argument, however it's important to be able to work through such a question to a logical answer based on math and science.

We know the  orbit of the Moon. As early as the 1960s, observations of the exact paths of lunar orbiters led to very accurate calculations of the Lunar mass. Dividing this by the volume gives a number of density per cubic meter. For the Moon to be hollow, the material forming the hollow sphere would have to be that much heavier per unit volume. And that's not the case. Other scientific evidence exists, at the bottom of your link.

Maybe the earth is hollow. After all, moon mass gives the earth two rotational centers. One of them is the standard 24-hr daily rotational center. The other is the barycentre between the earth and the moon.

The barycentre is said to be about 1,100 miles below the earth's surface. Combined with the daily-center, during the formation of the earth, if the moon were already present, it might have kept earth material away from earth's center. There might be an actual "room" down in the center of the earth... probably not very big, but self sustaining because of certain geological forces.

After all, the suggested present structure of the earth is not factually known to be the way the earth really exists inside.

Its just a sphere,atleast that is how I am seeing it.

If earth is spehaere then all the solid planets supposed to be sphere.Anyway we need a drill to find out.

How long will it take us to be able to listen to the sounds in a deep hole on the moon, since there isn't any air on the moon to transmit sounds?

It would be interested if the Moon is an artificial space station that was created to stabilize the atmosphere and make Earth human friendly.
But, this needs a lot of technological advances that people didn't have in early years so I think that this option should be out of the table.

According to the Russian scientist theory, the moon object was brought here in ancient times past.  The moon is much older than the earth.

So this would speak to advanced ancient civilizations way before the earth. It is all kind of mind bending for sure. But Einsteins theory of relativity, was considered crazy and also String theory, is wild and incomprehensible.

This is the part of Science that is so exciting...allowing ones mind to open up to extraordinary concepts.

Yes, it's all very interesting, just reading ALL the different articles and reports. It's a lot to go through,  but food for thought.

Here is a fascinating eye witness account written by Astronaut Pete Conrad of the November 1969 Apollo 12 mission who said it was "ringing like a gong."

Then there is the matter of
Vasin and Shcherbakov Russian Scientists

It is interesting and extraordinary that it was 2 Russian scientists, both members of the distinguished Russian Academy of Sciences, (at that time it was known as the Soviet Academy of Sciences, ) that came up with this radical and controversial theory of a hollow moon in 1970.

The Russian Academy of Sciences, the RAS, established in 1724, and chartered by the government of Russia, is a highly reputable and esteemed network of a scientist dedicated to scientific research.


https://en.m.wikipedia.org/wiki/Russian_Academy_of_Sciences
 
Vasin's and Shcherbakov's theory was fringe,  to say the least. Claiming there is scientific evidence to back it up. Saying that the moon is much more Ancient than the earth and that its surface was composed of metals and elements that do not occur naturally on the earth such as brass, mica, and radioactive elements.

Also, mentioned that the craters on the moon are shallow and all about the same depth suggesting a tough outer surface.

Our own astronauts tried to drill into the surface and the craters and could not penetrate the surface.

The discussions of the unusual and precise size of the moon, all of which is of great benefit to us, but also an anomaly compared to sizes and positions of other moons in respect to their planets is also interesting.

More on it.

Thanks. I'm not here to argue or to try to prove anything but to just discuss these ideas and welcome thoughts on it.

..... the moon is much more Ancient than the earth and that its surface was composed of metals and elements that do not occur naturally on the earth such as brass, mica, and radioactive elements.

In the last decade, our satellites have used sensors to determine the elements on the lunar surface, the magnetism and gravitational changes, the temperatures, many other things.

These satellites are put into lunar polar orbits, so the Moon rotates below them, and over the course of a month they will gather data on the entire lunar surface.

That would mean those claims of a hollow moon with such a group of surface elements was wrong.

Is the moon hollow?

No.

[BADecker]

The moon is hollow, but not empty, as it is filled with hot nacho cheese... Mmm...

How can it be hollow if the so-called hollow is fill with something?... in this case, hot nacho cheese?

[Aaric]

It is not hollow. You can already measure the moon's weight by it's orbit and how it affects the planet.

It's a bit more than that, they claim that the shell around the hollow core is corresponding heavier...

[inlovewith]

Makes me wonder why some of you guys don't actually think that the moon is actually made of cheese.

The Moon rang like a bell
Between 1972 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.[16] This phrase was brought to popular attention in March 1970,[1] in an article in Popular Science.[17] When Apollo 12 deliberately crashed the Ascent Stage of its Lunar Module onto the Moon's surface, it was claimed that the Moon rang like a bell for 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.

[BADecker]

After studying the bell-ringing aspect of the moon, it was determined that there were simply large caverns in the moon. It's not that we don't have sensitive enough seismographs. Rather, it's not known for a fact how to best interpret the readings.

The moon is how wide? If it is hollow rather than honeycombed, it just might take penetrating to the hollow part to figure this out for sure. But we gotta get there first. Note that multitudes of people from the '50s and '60s who were hoping to be on the moon in a decade back then, are long dead and gone. Is our moon focus the best idea?

We haven't even gone very deep on the earth. Is the earth hollow?

"Ringing like a bell" does not imply hollow. Not sure where that inference came from.

Acoustic transmission in underground strata is well understood and is used for many purposes in geology and industry.

We are talking about many miles through different materials that are unknown. For example, science was surprised to find loads of water deep down under parts of the surface of the earth. Geological soundings should have made them aware of this water long before it was found. Seems to me that there is a lot to learn about how sound works through various materials at great distances.

This is not true! The Moon is hollow, and that's a fact. Because after Hitler fled with his remaining loyal troops in their flying nazi saucers to the Dark Side of the Moon, they started hollowing it out. This is true because youtube has a link.

True, there is a lot to explore right here and a lot of unknowns.
And there are some very interesting questions on that and also the moon.
Scientist are baffled by the moon and have come up with several theories as to how it got there. And this is one of them. This was not crazy persons or lunatic group. It was 2 scientists.
Is the moon much older than the Earth? Apparently it is. So that's a puzzle.
How to explain there processed metals, as brass, mica and titanium, and radio active material?

Also the moon is unusually large in proportion to other planets in our solar system.

It's large and light, being 1/4 the size of the earth but only 1.2% of the eatha mass and the volume is only 2% of the earth.
Nasa did say it had a similar composition to the earth but "significantly less dense." But  also the astronauts could not penetrate the surface with drills.

Another interesting anomaly is that the crater depths are all the same..whether they are large craters or small, the depth is uniform and relatively shallow.
So a lot to explore about that.

the first hand account of the astronaut who was actually there is fascinating.

It's natural to have a knee jerk resistance to anything that might shake up one's idea of the world. But an open mind goes a long way towards making progress in any area.

Of course the crater depths are not the same. Some craters are > 100 miles across, others are a few feet. Then there are craters from micrometeorites, which can only be seen with a microscope.

The particles in the dirt are not rounded by millions of years of weather like on earth, and there sharp edges cause them to pack tightly. This is why drilling down was difficult.

The size, weight and density of the Moon follow from it's elemental composition.
