Prehistoric Hi-Tech Nanospirals Barely Visible To The Naked Eye: Still Remain An Unsolved Mystery
A.Sutherland - AncientPages.com - Strange microscopically small nanospirals within the 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 and strange artifacts that the human eye can barely see - is still not explained.
There were many speculations regarding the nanospirals. Some said they are forgery, but alternative history researchers think the artifacts offer proof of advanced ancient high-tech knowledge.
However, the discovery of these prehistoric artifacts is very interesting, because the sophisticated technology required to make this kind of product - 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.
The nanospirals are mainly made of tungsten and their cores are tungsten or molybdenum. Ones discovered at a later date were also made of copper.
Fascinating is the spirals' proportion due to their surprising regularity, which indicates that they could only have been manufactured by mechanical means. So one can say their construction is artificial.
Their date of origin is estimated between 300,000 and 100,000 BC.
