The concept of a Hollow Earth, or the belief that our planet is hollow and possibly inhabited within, has been a part of various cultural mythologies and speculative theories. However, it's important to note that this idea is considered pseudoscientific by mainstream science today. Below is a list of what proponents of the Hollow Earth theory might consider as "evidence," although none of these points are accepted by the scientific community as proof of a hollow Earth:

1Earthquake Seismic Waves

The way seismic waves travel through the Earth is used by Hollow Earth believers to argue for an internal structure different from the solid layers accepted by geology. However, seismologists interpret these data as consistent with a solid Earth .Show More

2Mythological Accounts

Various ancient cultures have myths involving underground realms such as Greek mythology’s Hades or Norse mythology’s Svartalfheim . These stories are often cited by Hollow Earth theorists but are understood by historians as allegorical or symbolic rather than literal.Show More

3Admiral Byrd’s Alleged Diaries

Some proponents point to accounts attributed to Admiral Richard E. Byrd, who reportedly wrote about flying into the North and South Poles and discovering lush lands beyond. These diaries are disputed and not recognized by official records .Show More

4Symmes’ Theory

In the 19th century, John Cleves Symmes Jr. proposed that the Earth was hollow with entrances at the poles. His theory gained some public interest but lacked empirical evidence .Show More

5Unusual Sounds

Reports of strange sounds coming from the Earth, such as booms or hums, have sometimes been interpreted as evidence of a hollow interior. Scientific explanations usually attribute these noises to natural phenomena like atmospheric conditions or geological activities .Show More

6Anomalous Temperature Gradients

Some claim that temperature gradients in deep mines or boreholes do not match predictions for a solid Earth. Geothermal studies, however, confirm the expected heat flow from the Earth’s core .Show More

7Magnetic Field Anomalies

Variations in the Earth’s magnetic field have been suggested as evidence for a hollow Earth, but these variations are well-explained by the dynamo effect caused by the movement of molten iron within the Earth’s outer core .Show More

8Literary Works

Books like Raymond Bernard’s "The Hollow Earth" recount tales of explorers and their encounters with inner-Earth civilizations . Such works are considered fiction or speculative non-fiction and lack credible evidence.Show More

9Tales of Subterranean Civilizations

Legends of subterranean cities or races, such as Agartha, are often brought up by Hollow Earth enthusiasts . These are typically viewed as folklore without historical basis.Show More

10UFO Sightings Near Poles

Some believe that UFO sightings near the poles could indicate access points to a Hollow Earth where advanced beings reside. This hypothesis lacks substantiation and is not supported by scientific investigation .Show More

Note:

It is crucial to approach these claims critically. The scientific consensus based on extensive research and observation supports the view that the Earth is a nearly spherical body composed of several solid layers surrounding a molten outer core and a solid inner core. While the Hollow Earth theory captures the imagination, there is no substantial scientific evidence to support its validity. The listed points above serve more as elements of popular culture and alternative histories rather than scientific evidence .
