Have you heard about the bizarre Hollow Earth Theory?

Amazingly, despite all the studies, measurements, evidence, and knowledge available about the composition of our planet, there is a crazy theory that the earth would be hollow. And the people who defend this idea take this matter very seriously, having even launched web pages, articles and books devoted entirely to this topic.

Hollow Earth Theory has been around the scientific community for a few centuries, and one of its earliest advocates was Edmund Halley, who launched his version of the theory in the 17th century. The surname sounds familiar, doesn't it? Well, it was Halley's calculations - a respected British astronomer - that determined when the comet named after him would pass again near Earth.

Halley was fascinated by our planet's magnetic field, and realized that the direction of the field varied slightly over time, which led him to argue that this would only be possible if there were several magnetic fields. It was then that the astronomer concluded that the earth was hollow, and that it - in order to explain the variations in the magnetic field - was composed of four spheres, one located within the other.

The astronomer also believed that the interior of the earth was inhabited and that there was a bright atmosphere inside and, for Halley, the aurora borealis occurred when gases from this inner atmosphere escaped through the earth's crust. Over time, other theorists eventually adopted Halley's ideas, each adding their own theories to the original idea.

Among the ideas that emerged, the Swiss mathematician Leonhard Euler replaced the theory of the four spheres with the idea that there was only one hollow layer inside the earth. It would even have a sun almost a thousand kilometers long, which would offer light and warmth to the advanced civilization that lived there. And later Scottish mathematician John Leslie came up with the idea that there were two suns instead of just one.

One of the greatest supporters of Hollow Earth Theory was the American John Symmes, who, besides believing that our planet was hollow, said that there were two entrances to the earth's poles - almost 6, 500 and almost 9, 700 kilometers in diameter respectively - to this inner world.

The US government even sent an expedition to Antarctica to find such an entrance, and although the explorers found no opening, they eventually found evidence that this region of the planet was not just a huge ice cap, but an ice cap. that was a continent.

In the 19th century, the discovery of a mammoth in Siberia served as evidence for the theory, and Marshall Gardner - another proponent of the idea - said the animal had remained so well preserved because it had recently died after leaving the North Pole opening. and die frozen. Gardner believed that other animals thought extinct also lived freely within the planet, and that Eskimos and Mongols originated there.

The Hollow Earth Theory is also related to the emergence of a crazy sect - the Vril Society - of which several senior members of the Nazi army were part. There is even a story that Hitler would have sent an expedition to Antarctica to explore the underworld and discover the creatures that lived there - as the Nazis believed, they knew how to operate ships and travel to the moon.

From theory to fantasy

Over time and with the discoveries that have taken place over the years, Hollow Earth Theory has turned into a theme of science fiction and fantasy. After all, modern geology points out that the earth is mostly made up of a solid mass, no satellite imagery or probes or astronauts captured it ever showed any opening at the poles, and no expeditions to these places revealed any entry.

Perhaps the idea that has the most plausible aspects is that presented in Julius Verne's famous book, "Journey to the Center of the Earth, " in which he describes the existence of underground caves — not spheres and suns — in which life forms existed. And Verne's book is not completely wrong, after all, scientists have discovered whole microorganisms and ecosystems capable of surviving for thousands of years in such environments.
