South Africa slotted metal ball: the so-called extraterrestrial civilization is a joke

The metal ball below is called South Africa groove metal ball.

It was discovered in Dar, a small town in the central part of South Africa's northwest province.

Local miners have been digging, also known as Klerksdorp balls.

These dark reddish-brown spheres are somewhat flat,

The size varies from less than one centimeter to ten centimeters, and some have three parallel grooves around the equator.

Therefore, it is called a grooved metal ball.

This metal ball is not because its shape is so special and so on.

But judging from its "age"-3 billion years!

"My God!"

"3 billion years!"

"At that time, there were no humans. How can there be such a delicate sphere and how many grooves are drawn on both sides? "

Of course, the American naturalist who first saw it at that time naturally associated it with an "alien civilization".

Because the earth was still young 3 billion years ago, it simply could not accommodate the intelligent life that could create these metal balls.

Klerksdorp ball is a term coined by American naturalist and cryptographer.

Used to represent objects of historical, archaeological or paleontological significance found under very rare or seemingly impossible circumstances.

These objects seem to provide evidence that intelligent creatures existed before human beings existed.

The only explanation seems to be that it came from an alien civilization.

South African slotted metal balls will be used by them to prove their point.

However, with the passage of time, the once mysterious sphere was gradually uncovered.

They are not mysterious at all.

In fact, these spheres were formed by volcanic deposits, volcanic ash or both 3 billion years ago.

These coagulants are usually oval or spherical.

Therefore, they are often mistaken for dinosaur eggs, alien debris or man-made objects.

South Africa's grooved metal sphere, the groove shown in the equatorial part of the sphere, is actually a natural product.

Because scientists have also found this kind of sphere with similar structure in other parts of the world.

For example, in Navajo, southeastern Utah, USA, iron ore sandstone with similar grooves and shapes was found.

We can see that there is a similar groove in the middle of the sphere.

For example, scientists in Shahari County, new york also found carbonate concrete with similar structure.

For another example, similar condensate has been found in Australia with a history of 2.8 billion years.

Similar spherical gels have been found in New Zealand, many of which are still very large.

Of course, in the arguments of many "conspiracy theory" advocates, South Africa's slotted metal balls often have this narrative:

In fact, NASA records have never said so.

In addition, these objects are not strictly spherical at all, and the so-called precise balance is untenable.

Another way of saying this is that the sphere is made of metal that is "harder than steel".

In fact, this statement is also untenable. Sphere is an alloy product, which consists of steel in different proportions and other elements in different proportions.

And high pressure and high temperature environment.

This is not special.

In short, in the process of exploring the world, we once again defeated "mysticism" and "conspiracy theory"!
