"One either has to harness the power of a star, or to find something called “exotic” matter (which falls up, rather than down) or find a source of negative energy."

"The Vril Force or Vril Energy was said to be derived from the Black Sun, a big ball of "Prima Materia" which supposedly exists in the center of the Earth, giving light to the Vril-ya and putting out radiation in the form of Vril."

"Earth’s internal magnetism creates a region around the planet known as the magnetosphere"
"Our magnetosphere is part of a dynamic, interconnected system that responds to solar, planetary, and interstellar conditions – and it all starts deep inside Earth. As electrically charged, molten iron churns far below Earth’s surface, within the planet’s outer core, it generates a magnetic field large enough to extend far out into space."
