[1]alternative_right shares a report from ScienceAlert:
> A thorough investigation published in May 2023 found that the inner core of the Moon is, in fact, [2]a solid ball with a density similar to that of iron . To figure it out once and for all, [astronomer Arthur Briaud of the French National Centre for Scientific Research in France] and his colleagues collected data from space missions and lunar laser-ranging experiments to compile a profile of various lunar characteristics. These include the degree of its deformation by its gravitational interaction with Earth, the variation in its distance from Earth, and its density.
>
> ... they found that the lunar core is very similar to that of Earth â" with an outer fluid layer and a solid inner core. According to their modeling, the outer core has a radius of about 362 kilometers (225 miles), and the inner core has a radius of about 258 kilometers (160 miles). That's about 15 percent of the entire radius of the Moon. The inner core, the team found, also has a density of about 7,822 kilograms per cubic meter. That's very close to the density of iron. [...]
The research has been [3]published in Nature .

That's some dense cheese. It would probably break my teeth.

That's why it's still there. All the soft moons were already eaten.

That's what happens if you leave Wensleydale exposed to cosmic rays for billions of years.

Just don’t sit too close while looking for Santa’s workshop, masturbating about all the gifts you’ll get soon.
You’ll go blind.
And if your face stays like that, people will know why.

I like how the word “conspiracy theory” is just the new word for “believing falsehoods [religions are exempts]”. The composition of the moon is not a “conspiracy”; it is what it is. Alleging that China and the U.S.A. are secretly working together to keep people pacified is a “conspiracy” but this is just the composition of the moon.

No! The iron content proves it must be filled with well-aged cheddar!!!
Heretic!

No cheese filling. So we are all made from the same star dust.
