Welcome to our deep‑dive into 10 strange reports that keep the hollow Earth legend alive, where scientists, adventurers, and even dictators have claimed secret passages, inner suns, and hidden civilizations.
10 Holes In The Poles
In 1906 the intrepid writer William Reed released The Phantom of the Poles, a tome in which he argued, with what he considered irrefutable evidence, that the planet’s interior was not solid rock at all but a cavernous realm awaiting discovery.
During a newspaper interview Reed proclaimed that a hollow Earth offered the “most natural way to account for the flattening of the Earth in the polar regions.” He went further, insisting that massive openings sliced straight through both poles, allowing sunlight to stream in and illuminate the ice‑capped world like “gems of living crystal” amidst the frozen seas.
Decades later Reed’s book has achieved cult‑classic status among hollow‑Earth enthusiasts, cementing his name as one of the movement’s most colorful champions.
9 Icebergs From Inside The Earth
Another head‑scratching claim from the hollow‑Earth crowd holds that the hulking icebergs drifting in our oceans are not born of frozen seawater at all, but are instead expelled from the planet’s inner chambers.
William Reed, the same author of the polar‑hole theory, told The Sunday Times that these towering blocks of ice “are formed inside the Earth and come sailing out of the polar holes, passing round the edge and emerging in the ocean on the outside.”
Modern satellite imagery, however, has never caught a glimpse of such an event, leading conspiracy‑theorists to allege a massive cover‑up designed to keep the inner world hidden from the public.
8 Cellular Cosmogony
By 1908 a different strand of hollow‑Earth thinking captured headlines worldwide. Dr. Cyrus R. Teed asserted that humanity lives not on the planet’s outer skin but inside a gigantic cellular structure, with the Sun perched at the very centre.
According to Teed, three concentric atmospheres surround the central Sun, the innermost of which is composed of hydrogen, rendering the star itself invisible. What we perceive as daylight is merely the Sun’s energy diffusing through roughly 1,400 kilometres of intervening material.
7 The Center Is Inhabited
The notion of a populated interior predates the 20th‑century boom in hollow‑Earth literature. In an 1884 newspaper report, Americus Symmes announced a lecture on the theories first advanced by his father, John Cleves Symmes Jr., who had circulated a pamphlet in the early 1800s describing life beneath the crust.
John Symmes died in 1829, but his son kept the idea alive, even claiming that three men had actually ventured inside, met the native inhabitants, and catalogued the language and agricultural practices of this subterranean society.
The lecture sparked a wave of curiosity, cementing the belief that an inner world populated by people and crops was more than mere fantasy.
6 Because Globes Are Hollow
While academic scientists dismissed hollow‑Earth ideas, certain religious writers in the late 19th century embraced them, arguing that a divine creator would not waste effort fashioning a solid sphere.
One 1893 commentator asked, “Would not the animals on the Earth be more solid at their centre than their circumference, instead of being strongly ribbed near the surface, so as to support the greatest pressure, leaving a cavity in the center capable of active operation?”
The same writer later quipped, “Do not our globe makers understand that a hollow globe is preferable to a solid? If not, why do they make them hollow?”—a rhetorical flourish that, while whimsical, underscored the persistence of the hollow‑Earth motif.
5 A Solid Earth Is Too Heavy For Orbit
Proponents of a cavernous planet often argued that a solid Earth could not maintain its orbital position around the Sun, making hollowness a necessary condition for celestial stability.
In a 1905 lecture, George Ipson claimed that without an internal void the Earth would be too massive to “retain its position in ethereal space.” He also maintained that sunlight entered through gigantic polar apertures, bathing the inner world in a perpetual glow.
According to Ipson, a simple air‑carriage could descend through these openings, allowing a traveler to reach the subterranean realm with “easy control of the operator.”
4 Now The Aurora Borealis Makes Sense
Early 20th‑century hollow‑Earth scholars also offered a dazzling explanation for the northern lights, suggesting they were not solar phenomena at all but reflections of inner‑world fires.
They argued that the inner Earth is lined with luminous crystals that bounce the Sun’s rays around the cavity, causing the brilliant, dancing curtains of light we see as the aurora borealis when the reflected energy escapes through the polar openings.
3 Germany Believed
Post‑World‑War II rumors claim that Adolf Hitler and many German citizens subscribed to the Hohlweltehre, the “hollow Earth doctrine.” Internet folklore even suggests Hitler escaped to a subterranean refuge after the war.
A 1954 Sydney newspaper article reported that “Hitler adopted it, along with fortune‑telling, astrology, and locating enemy ships by pendulum swing over a map,” lumping the theory together with other occult practices to discredit it.
2 Still Sought After
The hollow‑Earth obsession hasn’t faded. In 2002, Art Bell’s “Coast to Coast AM” featured Dallas Thompson, who claimed a near‑death experience revealed secret knowledge about an inner world.
Thompson announced plans for a 2003 expedition to the polar opening, but after publishing his memoir Cosmic Manuscript, he mysteriously vanished, fueling speculation about a possible cover‑up.
Other modern believers have even relocated to Alaska, hoping proximity to the North Pole will increase their chances of locating the fabled entrance.
1 Blame It On Halley
The hollow‑Earth narrative can be traced back to 1672, when the famed astronomer Edmond Halley—best known for the comet that bears his name—proposed a series of concentric shells surrounding a central void.
Halley described the Earth as a set of layers: an outer shell we walk on, a hollow space filled with air, another shell, another air pocket, and finally a solid core. He imagined three luminous air zones that could sustain life and were constantly illuminated by “luminous air.”
Although Halley’s ideas were eventually eclipsed by modern geology, they laid the groundwork for the myriad strange reports that continue to capture imaginations today.
