Rumor: "Iron Silicide" is an Alien "Black Box"
refute:
1: Yuri Lafbin, chairman of the "Tungus University Phenomenon" Foundation, discovered the silicon crystal "iron silicide" that cannot be formed naturally in nature.
Fact: Natural iron silicide, that is, ferrosilicon ore was first discovered in the Devonian sandstone on the Azov coast of the Soviet Union. At that time, it was speculated to be of meteorite origin. The discoverer was also a geologist of the former Soviet Union. In addition, there are many domestic reports. And many of them are not meteorites at all and are therefore magma, which has been clearly pointed out in the literature.
2: Neon, xenon, argon... such a combination of material components is impossible to form in the earth environment. Fact: Neon, Xenon, and Argon are often present in geological samples,
And you can use this to conduct in-depth research on the mineralization conditions and time, and you can see the corresponding references. 3: Even the most powerful laser instrument can only leave a slight trace on the "iron silicide" Fact: The Mohs hardness of ferrosilicon is about 6.5
It is related to the specific type, hardness and even
Not as good as common quartz (ie, crystal, which has a Mohs hardness of 7).
To sum up, it can be seen that the so-called "iron silicide" of the so-called Tunguska discovered aliens was imported foreign rumors. There are a large number of scientific flaws, which are not credible at all, and should not be spread.
