I'm aware of the flat earth nutcases but stumbled across this video and apparently hollow earth theory is a thing? Anyone here familiar with this lunacy? 
It's not hollow, we've checked. Well at least the Russians have dug pretty deep. The Moon, now that's hollow.
Neal Zumbro - It's not hollow, we've checked. Well at least the Russians have dug pretty deep. The Moon, now that's hollow.Wat
This is the kind of thread that built the OG

Yeah, got high and went down that rabbit hole before. Basically, worldwide Folklore since the 1500s has told of middle earth and the like, Northern Ireland's Druids particularly. Also, in Missouri there is old Native American folklore. It's totally disproven because of magnetism. We don't really know what is below us. In reality, (this is proven science) we have only drilled less than 1% into the earths surface, yet we can reasonably speculate molten metal/rock is down there spinning because we have magnetism. Compasses and the magnetic poles couldn't exist otherwise.
That's where Pellucidar is.
With dinosaurs and stuff.

It's a very strange theory considering the amount of evidence we have against the earth being hollow. It would be cool though saw an episode of ancient aliens about it that was pretty cool.

"UFOlogists have proposed that the moon, believed to be a natural satellite of Earth, is, in fact, a huge spaceship, a gigantic UFO, parked in orbit around the Earth by an advanced technological civilization.
The Spaceship Moon Theory claims that the moon, as an alien UFO parked in orbit around the Earth, has a hollow inside. In other words, the moon is a hollowed-out artificial structure containing an underground base serving also as the interior of a gigantic UFO spaceship."
I thought they figured out the earth was filled with lost socks
Here you go. Worth the FRAT.
Editor’s Note: This essay from Jim Marrs exploring a number of controversial ideas about the Moon was originally published in Above Top Secret: Uncover the Mysteries of the Digital Age (Disinformation, 2008).
Despite six announced visits by U.S. astronauts between 1969 and 1972, the Moon remains a riddle to scientists in many regards. The solutions to these riddles could indicate an alien aspect of our familiar Moon.
Called “the Rosetta Stone of the planets” by Dr. Robert Jastrow, the first chairman of NASA’s Lunar Exploration Committee, scientists had hoped by studying the composition of the Moon, to resolve some of the mysteries of how our planet and solar system came into existence.
However, six Moon landings later, science writer Earl Ubell declared, “… the lunar Rosetta Stone remains a mystery. The Moon is more complicated than anyone expected; it is not simply a kind of billiard ball frozen in space and time, as many scientists had believed. Few of the fundamental questions have been answered, but the Apollo rocks and recordings have spawned a score of mysteries, a few truly breath-stopping.”
Among these “breath-stopping” mysteries or anomalies as scientists prefer to call them is the fact that the Moon is far older than previously imagined, perhaps even much older than the Earth and Sun. By examining tracks burned into Moon rocks by cosmic rays, scientists have dated them as billions of years old. Some have been dated back 4.5 billion years, far older than the Earth and nearly as old as the solar system.
The Moon has at least three distinct layers of rocks. Contrary to the idea that heavier objects sink, the heavier rocks are found on the surface. And there is a definite disparity in the distribution of minerals. Ubell asked, “If the Earth and Moon were created at the same time, near each other, why has one body got all the iron [the Earth] and the other [the Moon] not much?” asked Ubell. “The differences suggest that Earth and Moon came into being far from each other, an idea that stumbles over the inability of astrophysicists to explain how exactly the Moon became a satellite of the Earth.”
The Moon is extremely dry and does not appear to have ever had water in any substantial amounts. None of the Moon rocks, regardless of where they were found, contained free water or even water molecules bound into the minerals. Yet Apollo 16 astronauts found Moon rocks that contained bits of rusted iron. Since oxidation requires oxygen and free hydrogen, this rust indicates there must be water somewhere on the Moon.
Furthermore, instruments left behind by Apollo missions sent a signal to Earth on March 7, 1971, indicating a “wind” of water had crossed the Moon’s surface. Since any water on the airless Moon surface vaporizes and behaves like the wind on Earth, the question became where did this water originate? The vapor cloud eruptions lasted 14 hours and covered an area of some 100 square miles, prompting Rice University physicists Dr. John Freeman, Jr. and Dr. H. Ken Hills to pronounce the event one of “the most exciting discoveries yet” indicating water within the Moon. The two physicists claimed the water vapor came from deep inside the Moon, apparently released during a moonquake.
NASA officials offered a more mundane, and questionable, explanation. They speculated that two tanks on Apollo descent stages containing between 60 and 100 pounds of water became stressed and ruptured, releasing their contents. Freeman and Hills declined to accept this explanation, pointing out that the two tanks — from Apollo 12 and 14 — were some 180 kilometers apart yet the water vapor was detected with the same flux at both sites although the instruments faced in opposite directions. Skeptics also have understandably questioned the odds of two separate tanks breaking simultaneously and how such a small quantity of water could produce 100 square miles of vapor.
Moon rocks were found to be magnetized—not strong enough to pick up a paper clip, but magnetic nevertheless. However, there is no magnetic field on the Moon itself. So where did the magnetism come from?
The presence of maria, or large seas of smooth solidified molten rock, also presented a mystery. These maria indicate nothing less than a vast outpouring of lava at some distant time. It has now been confirmed that some of the Moon’s craters are of internal origin. Yet there is no indication that the Moon has ever been hot enough to produce volcanic eruptions. Another puzzle is that almost all — four-fifths — of the maria are located on the Moon’s Earthside hemisphere. Few maria mark the far side of the Moon, often erroneously referred to as the “dark side.” Yet the far side contains many more craters and mountainous areas.
In comparison to the rest of the Moon, the maria are relatively free of craters suggesting that craters were covered by lava flow. Adding to this mystery are the mascons — large dense circular masses lying 20 to 40 miles below the center of the Moon’s maria. The mascons were discovered because their denseness distorted the orbits of our spacecraft flying over or near them. One scientist proposed that the mascons are heavy iron meteorites that plunged deep into the Moon while it was in a soft, formable stage. This theory has been discounted since meteorites strike with such high velocities, they would vaporize on contact.
Another mundane explanation is that the mascons are nothing more than lava-filled caverns, but skeptics say there isn’t enough lava present to accomplish this. It would seem these mascons are huge disk-shaped objects possibly of artificial construction. It is unlikely that large circular disks located directly under the center of the maria like a giant bulls-eye happened by accident or coincidence.
Between 1969 and 1977, Apollo mission seismographic equipment registered up to 3,000 “moonquakes” each year of operation. Most of the vibrations were quite small and were caused by meteorite strikes or falling booster rockets. But many other quakes were detected deep inside the Moon. This internal creaking is believed to be caused by the gravitational pull of our planet as most moonquakes occur when the Moon is closest to the Earth.
An event occurred in 1958 in the Moon’s Alphonsus crater, which shook the idea that all internal moonquake activity was simply settling rocks. In November of that year, Soviet astronomer Nikolay A. Kozyrev of the Crimean Astrophysical Observatory startled the scientific world by photographing the first recorded gaseous eruption on the Moon near the crater’s peak. Kozyrev attributed this to escaping fluorescent gases. He also detected a reddish glow characteristic of carbon compounds, which “seemed to move and disappeared after an hour.”
Some scientists refused to accept Kozyrev’s findings until astronomers at the Lowell Observatory also saw reddish glows on the crests of ridges in the Aristarchus region in 1963. Days later, colored lights on the Moon lasting more than an hour were reported at two separate observatories.
Something was going on inside the volcanically dead Moon. And whatever it is, it occurs the same way at the same time. As the Moon moves closer to the Earth, seismic signals from different stations on the lunar surface detect identical vibrations. It is difficult to accept this movement as a natural phenomenon. For example, a broken artificial hull plate could shift exactly the same way each time the Moon passed near the Earth.
There is evidence to indicate the Moon may be hollow. Studies of Moon rocks indicate that the Moon’s interior differs from the Earth’s mantle in ways suggesting a very small, or even nonexistent, core. As far back as 1962, NASA scientist Dr. Gordon MacDonald stated, “If the astronomical data are reduced, it is found that the data require that the interior of the Moon be less dense than the outer parts. Indeed, it would seem that the Moon is more like a hollow than a homogeneous sphere.”
