The Buga Sphere artifact reportedly features "Proto-Sanskrit" writing around its perimeter, which Greer suggests is the root of all Indo-European languages. Microscopic fiber optics were found embedded in the sphere's resin, and the device exhibits "mass cancellation" effects, allowing it to move without identifiable propulsion. Greer notes that the sphere's weight fluctuated from 4 pounds to 22 pounds as its internal circuitry allegedly died.
