Hollow Earth

"Is it really true that the Earth is hollow and inhabited inside?"

The Hollow Earth theory was first proposed in 1692 by the renowned astronomer and mathematician Edmond Halley. It suggests that the Earth is a hollow sphere made up of several concentric layers, much like Russian dolls stacked within each other. Openings to the inner Earth are believed to exist at the poles. Although the theory has long been debunked by modern science, some esoteric thinkers still dream of undiscovered treasures and secrets hidden within the Earth’s interior. There, they believe, a highly advanced civilization – the Kingdom of Agartha – exists, with technologies far superior to our own.
Completely hollow? Well, hope dies last.
