The ball from the Klerksdorp Museum17564x 04. 11. 2013 1 Reader
These perfect small spheres were found by miners at Wonderstone Silver Minerals in Ottosdal (South Africa). There were more than 200 small balls found here. Each has a diameter from 1 to 4 cm.
The spheres are made of a nickel-steel alloy that naturally does not occur naturally on Earth. According to the surrounding layers in which the objects were found, spheres are dated to more than 3 billion years.
Some spheres have a very thin shell, and if one breaks, there's something like a sponge-like material inside, but it quickly breaks into dust in the air.
The ball is held by Roelf Marx, curator of the South African Klerksdorp Museum, and is a great mystery to him. No one knows how the bike was made or where its origin is.
Some of the balls had the curator reevaluated at NASA to verify that they were created with an accuracy that can only be achieved in a stateless state.
There are witnesses who saw spheres spontaneously rotate in the showcase - including the curator himself. (Let's recall a similar case with the statue of the Egyptian god Osiris.)
