Corrugated Sphere, South Africa
From series “Most Curious Artifacts of Extraterrestrial Origin”
The unique wavy spheres were first discovered by the miners in the Republic of South Africa a few decades ago. Since then, they have been regularly found by the workers on the depths. The spheres have different structure. Some of them are uniform and consist of the modern science of unknown alloy. The other spheres are hollow. During the sawing, the porous white matter has been found in them. A single similar element is the small furrows, which are called the 'equator'.
