While Flat Earthers have welcomed the explosion in articles and videos espousing their cause in recent years, it undercuts their claim that a dangerous truth is being repressed. Logically, a repressed idea is one that is not being heard, which brings us to the idea of a hollow Earth.
There are websites and essays that tout this notion, but these receive a tiny fraction of the notice that those produced by Flat Earthers receive. The proposal has been around in various forms for millennium. Early hollow Earth enthusiasts idealized inhabitants as deeply evolved, supremely healthy beings who were peaceful, prosperous, and rippling with muscles. A few religious movements sprouted from this idea. These days, Earth’s insides are mostly thought to house some combination of superior 12-foot humanoids, wayward Greenlandic Vikings, immortal peace-lovers, the 10 Lost Tribes of Israel, and Third Reich leadership. Those peace-lovers have their work cut out for them if those last two groups are both present.
Those favoring a more rational approach engaged in genuine scientific pursuit to find out if Earth was hollow and at least two excursions were made in the spirit of exploration to try and find the entry point. Edmond Halley wondered if auroras were caused by a combination of ferrous matter and a supple magnetic pole. He pondered that an aurora could be caused by luminous gases spewing from a polar door. To explain anomalous compass readings, Halley also suspected Earth might have a hollow shell about 500 miles thick, followed by two inner concentric shells, then an innermost core.
Such speculation was admirable, as was his method of using observation and testing using proper protocols. By employing these channels, he and later scientists learned such notions were incorrect, yet some hollow Earthers continue to cite Halley as a supposed proponent. This is what Steven Novella meant when he said that such groups use science like a drunk uses a lamppost: For support, not illumination. About a half century later, mathematician and physicist Leonhard Euler talked what would happen if one drilled a hole all the way through Earth and dropped a stone into the opening. He never said Earth was hollow; in fact, drilling all the way through would be unnecessary if it was. Yet he too is sometimes touted by hollow Earth proponents as a believer.
The idea of subterranean realms made appearances in various mythological and religious texts, with it sometimes being the destination of departed souls. Greeks, Celts, Hindus, Nordics, Tibetans, Jews, Mesopotamians, Native Americans, and Christians have all embraced this notion in some form. While the port of entry is usually near one or both poles, prospective entrances have been surmised in locales as diverse as the Amazon, the Himalayas, and downtown Paris. Through an unexplained mechanism, these portals open to enable travel between the inner and outer portions of our planet.
The most common hollow Earth hypothesis in the 19th Century was that we were the ones on the inside. Championed by Cyrus Teed, this idea held that all observed celestial bodies were inside Earth with us. He founded a religious movement based around the idea and sprinkled it with pseudoscientific guesses about light, gravity, and other natural phenomena.
Later, Nazis got in on the act, with Luftwaffe pilot Peter Bender devising another mystical movement whose tenets included a vacuous planet. There exist tiny pockets of both fascists and non-fascists who think Third Reich leaders escaped to these locales, usually aboard flying saucers.
The idea of us being on the outside is more attractive because getting to the other side would be much easier that way. So the concave planet has few adherents anymore and John Symmes was an early promoter of the reverse notion. He wanted to make a North Pole expedition to get inside but was unable to obtain funding. Jeremiah Reynolds did go on such a jaunt in the opposite direction, but if he found an Antarctic opening, he kept the location to himself.
While previous motivations were religion or idealism, those have largely been replaced with a 21st Century conspiratorial flavor. Now, an anonymous, malevolent “they” hides the hollow Earth truth from the populace, with a few brave rebels tirelessly trying to convince the sheeple.
There are a few exceptions. Dianne Robbins, whom I’ve previously profiled, sees inner Earth as a paradise populated by immortal, absolutely peaceful beings with whom she communicates telepathically. And on ourhollowearth.com, the site maintainer likewise considers our planet’s innards to be a terrestrial wonderland, in this case the place where the 10 Lost Tribes of Israel hang out. Tribe members are responsible for flying saucer sightings, as they leave their subterranean sanctuary to ward off dangers to Outer Earthlings.
Among those who think these truths are being hidden rather than just not widely known, Raymond Bernard claims many early polar explorers were engaged in a secret mission to find these openings and reach the inhabitants. Fellow author Jan Lamprecht writes that evidence for a hollow Earth includes animal migration and early maps having been changed, which he thinks suggests subterfuge.
However, reasons to reject these hollow Earth hypotheses are found in evidence from seismic activity, gravity, and density.
With regard to the first of those, the time it takes seismic waves to travel through and around Earth is inconsistent with an empty sphere. Such evidence shows Earth is filled first with solid rock, then liquid nickel-iron alloy, and finally solid nickel-iron.
As to the proof provided by gravity, massive objects tend to clump together and create solid objects like stars, satellites, and planets. Such a configuration is a way to reduce the gravitational potential energy of the object being formed. Additionally, ordinary matter is too weak to support a hollow planet against gravity’s ample force.
Finally, we consider density and that’s not a reference to hollow Earthers’ mental acumen. Based on the size of Earth and the force of gravity on its surface, the average density of the planet is 5.5 grams per cubic centimeter. However, densities of surface rocks are only half that. This is crucial because if any sizable chunk of Earth were hollow, its average density would be much less than what the density of its surface rocks is.
While doing background work and compiling my information for this post, I could find no proponents or websites extolling the concept of a flat, hollow Earth. Sounds like repression to me.
