Brooks Agnew is the former lead physicist North Pole Hollow Earth Expedition. According to Agnew, current scientific data does not support the plate tectonic model, which theorizes the Earth's crust floats atop a pool of magma around a solid core. Agnew said there are reports of at least 8 major races and 200 minor races living in the interior of the Earth.
Brooks also noted there is research that shows there could be a large ocean that lies underneath the crust of the Atlantic ocean. Finding the Inner Earth could prove to be especially beneficial if the planet faces a global catastrophe, he said. According to a manuscript found in Abydos, Egypt, the ancient Egyptians might have fled to the Inner Earth to escape a cataclysm, possibly at a desert town called Damenhur.
The Hollow Earth hypothesis proposes that the planet Earth either is entirely hollow or otherwise contains a substantial interior space. The concept of a hollow Earth recurs many times in folklore and as the premise for subterranean fiction, a subgenre of adventure fiction. Agartha (sometimes Agartta, Agharti, Agarta or Agarttha) is a legendary city that is said to be located in the Earth's core. It is related to the belief in a hollow Earth and is a popular subject in esotericism.
