This theory has become How Findings From the Apollo Missions Led to the Hollow Moon Conspiracy Theory / Popular Mechanics popular after the experiments of the Apollo 12 expedition in 1969. Then the first artificial moonshake was caused on the Earth's satellite: first, astronauts placed seismometers on the Moon, and then dropped the module, the impact of which was close in power to the explosion of a ton of TNT. The results were unexpected. Vibrations on the moon were much stronger and several times longer than on our planet during earthquakes. The experiment was repeated by several subsequent US expeditions — the result was identical. The moon was then figuratively compared to a bell that rings after impact. And for conspiracy theorists, it was a sign: it turns out that the Earth's satellite is hollow, otherwise why would it vibrate like that.
In fact, the Moon consists of What Is the Moon Made Of? / NASA consists of several layers, including the mantle and the core. Scientists did not take this information from the ceiling: they were helped to understand the composition of the satellite by numerous studies of its gravity, rotation and other characteristics. And the difference in vibrations is explained simply: The moon is more Understanding Moonquakes / Phys.org it is hard and dry, like a piece of stone or metal; there is a lot of water on the Ground, which makes the vibrations fade faster.
Do you remember what pencil you used to draw the Sun with when you were in school? Probably yellow. But if you look at the sky now, it turns out that the star is rather white. Which means that something has happened to her in recent years! At least, this is the opinion of adherents of the theory of the fading Sun. The idea is not very fresh: similar thoughts were expressed The Sun Used to Be Yellow, According to This Cosmic Conspiracy Theory / Rolling Stone back in 2001. She attracted a new wave of attention in 2023, after the post of British journalist Jacqui Deevoy. The girl wrote that a guy in his 20s laughed at her when she said that the Sun was different in her childhood.
In fact, nothing happened to the star. And it is not always white in the sky. In reality, the Sun emits What Color is the Sun?? / NASA rays of different spectra. But the Earth's atmosphere scatters the blue ones more than the red ones. The lower the sun sinks, the more noticeable this effect is. Therefore, at the zenith, the Sun seems almost white, and at sunset it can even be seen orange or red. The yellow pencil from childhood is just a convenient tool to depict a star on a blank sheet: do not draw white on white.
And no, our planet did not collide with this space object — it just tore it apart Could the Earth be swallowed by a black hole? / ESO Supernova Exhibition would be in pieces. But the Earth (or rather, the entire Solar system) could have been born inside a black hole. This theory is really being discussed in scientific circles and is called Schwarzschild Cosmology and Black Hole‑ception! / HADRON by Schwarzschild cosmology. She suggests that the appearance of our universe is the result of the explosion of a singularity point inside a supermassive black hole.
If this version is true, then the cosmos looks like a matryoshka doll. Other universes are hiding in the holes of one universe — and so on indefinitely. But it is impossible to check how things are in reality — at least for now.
