The Klerksdorp Sphere
Over the last few decades, miners in South Africa have been digging up mysterious metal spheres. Origin unknown, these spheres measure approximately an inch or so in diameter, and some are etched with three parallel grooves running around the equator. Two types of spheres have been found: one is composed of a solid bluish metal with flecks of white; the other is hollowed out and filled with a spongy white substance. The true mystery lies in its age - the rock in which they where found is Precambrian and dated to 2.8 billion years old. Who made them and for what purpose is unknown.
Roelf Marx: "There is nothing scientific published about the globes, but the facts are: They are found in pyrophyllite, which is mined near the little town of Ottosdal in the Western Transvaal. This pyrophyllite (Al2Si4O10(OH)2) is a quite soft secondary mineral with a count of only 3 on the Mohs' scale and was formed by sedimentation about 2.8 billion years ago. On the other hand the globes, which have a fibrous structure on the inside with a shell around it, are very hard and cannot be scratched, even by steel."
"It also seems that the spheres are so delicately balanced that, even with modern technology, they would need to have been made in zero gravity. The story goes that scientists at NASA were totally flawed when they examined them, and were unable to come up with any explanation." However some of the photographs do not seem to support this.
All of the spheres found to this point are curated at a number of museums throughout Africa, Europe, and North America.
