The Hollow Earth

Agharta
Agharta, is a legendary kingdom believed to exist within the Earth’s core. This concept is tied to the hollow Earth theory and has been a popular topic in esoteric traditions. The idea of Agartha first emerged in the 19th century through Louis Jacolliot’s writings, where he mentioned an ancient city called ‘Asgartha’ that was destroyed around 5,000 years ago. French occultist Alexandre Saint-Yves d’Alveydre further popularized Agartha in his 1886 book, describing it as a hidden kingdom that preserves the original language of humanity. Agartha is often linked to Shambhala, a mythical kingdom in Tibetan Buddhism, and is sometimes depicted as an advanced subterranean city in modern media, such as video games. This blend of myth, history, and modern interpretations makes Agartha a fascinating subject within occult and esoteric traditions.

Historical Background
According to the hollow earth theory, there is a significant amount of space inside the Earth or it is completely hollow. Here are some salient features of this theory:

Origins: The concept has ancient roots and can be found in a number of mythology and folktales. For instance, the Tibetan Buddhist tradition speaks of an ancient city within the Earth called Shamballa, and the Greeks believed in caves going to the underworld1.

Scientific Disproof: Although Edmond Halley made significant contributions to the idea in the late 17th century, scientists like Pierre Bouguer and Charles Hutton refuted it in the 18th century1.

Conspiracy beliefs: The Hollow Earth theory endures in contemporary conspiracy beliefs, despite being scientifically refuted. There are many who believe in Agartha, an underworld kingdom.

Subterranean Fiction: This type of adventure fiction, in which stories frequently take place in undiscovered worlds beneath the surface of the Earth, is also influenced by the idea.

Geophysical information: A wealth of information has been gathered by modern science that indicates the Earth is not hollow. Seismic wave behavior and Earth's density both point to a solid interior.

Books and Media: The Hollow Earth theory has been portrayed as a fanciful world with its own ecosystems and civilizations in a number of books, films, and television programs.

As for what’s inside the Earth, it’s a fascinating question! Scientifically, the Earth’s interior is composed of hot metallic liquids, primarily iron and nickel, in the outer core, and solid iron in the inner core. However, the idea of a lost kingdom like Agartha is a captivating legend that sparks the imagination.
