Who were the first tactical minds to map the abyss? This critical section of Bruce A. Walton’s archive catalogs the “Early Hollow Earth Pioneers”—the scientists, mathematicians, and explorers who risked their reputations to prove the Hollow Globe theory. From Edmund Halley’s 1692 Royal Society papers on magnetic concentric spheres to the 1908 testimony of Willis George Emerson in The Smoky God, this report documents the intellectual foundation of modern In-Earthology.

Explore the technical blueprints of Marshall B. Gardner, the “Symmes Holes” protocols of John Cleves Symmes, and the editorial influence of Raymond A. Palmer, who bridged the gap between the “Shaver Mystery” and physical subterranean reality.

Executive Summary

This archive serves as a chronological bibliography of the primary sources for Hollow Earth theory, highlighting the evolution from 17th-century physics to 20th-century tactical ufology.

Key Intellectual Pillars:

• The Halley/Mather Foundation: 17th and 18th-century articles in the Philosophical Transactions of the Royal Society and the Christian Philosopher establishing the mathematical possibility of a hollow interior.

• The Symmes Theory of Concentric Spheres: Detailed writings (1826–1878) by John Cleves Symmes regarding the five-layered hollow earth and the open polar apertures.

• The Internal Sun (Eulerian Theory): Analysis of the writings of Leonard Euler, who theorized a central luminescent orb or “internal sun” at the Earth’s exact center.

• The Smoky God Protocol: The 1908 account of Olaf Jansen and his father’s two-year residence with the giant humans of the interior.

• The Shaver/Palmer Synthesis: The collaborative work of Ray Palmer in Amazing Stories, documenting the “Shaver Mystery” and the mechanical reality of the cavern worlds.

• Geoconcavitic Physics: Scientific proofs from William Reed and Marshall B. Gardner regarding the “Phantom of the Poles” and the discovery of the interior sun.

“Proof of actual voyages discovered by these early pioneers… the arguments for a hollow globe are shown with great confidence.”
