Euler, Leonard – 1707-1783. Euler was a famous Swiss physicist who was one of the most prominent mathematicians of his time, being the founder of the ‘calculus of variations‘, the inventor of ‘binary logarithms‘, and the third person in relatively modern times known to have advanced the theory of a hollow earth. Although he succeeded the scientists Halley and Mather, Euler was the first theorist to imagine the earth as w hollow globe devoid of additional “concentric spheres” as Symmes theorized, and theorized that the go-concavitic interior of the earth contained a single interior “sun” or luminescent orb at the exact center — some believing this to be a focal-point of auroral or electromagnetic energies — which is now the most widely accepted of all ‘Hollow Earth’ theories today.

Executive Summary

Section D & E serves as a technical dossier on ancient subterranean infrastructure, government continuity-of-operations (COOP) bases, and non-human biological signatures.

Key Analytical Pillars:

• The Moricz Tunnels: Documentation of the vast, ancient tunnel systems beneath Ecuador and Peru, reportedly containing artifacts of a “pre-deluge” civilization.

• The Lemurian Remains: Records of the “Bones” discovery in southwest Nevada, featuring the prehistoric remains of giant beings within an ancient tunnel.

• Government Refuge Cities: Analysis of the 96 secret underground cities established for bureaucrats and officials in the event of nuclear or natural cataclysm.

• The Habitable Interior: Scientific theories from Sir Humphrey Davy and Leonard Euler suggesting the Earth’s core is not molten, but a hollow, luminescent environment.

• The Arasareth Migration: Further insights into the Lost Ten Tribes and their reported migration to a “north country” within the Earth’s concavity.

• Technical Abductions: Descriptions of the Cergy-Pontoise case in France, involving an underground UFO base protected by “illusionary rock-like screens.”

“The earth is a hollow globe devoid of additional ‘concentric spheres’… containing a single interior ‘sun’ or luminescent orb at the exact center.”
