Strange microscopically small nanospirals within material that had to be at least 100,000 years old have been detected in several places, during a routine investigation of mineral deposits in the Ural Mountains in 1992.
The origin of these extraordinary but strange artifacts that the human eye can barely see – is still not explained.
There were many speculations regarding the nanospirals, later dismissed as forgery or a proof of an alien technology brought to earth.
However, the discovery of these prehistoric artifacts is very interesting, because the sophisticated technology required to make this kind of products – only goes back to the 1970s.
The spirals range between 3 cm and 0.0003 mm in size. Their remarkable regularity in structure and smooth surfaces, perforated in places, are only visible under an electron microscope.
