The 150, 000-year-old Chinese pyramids surprise researchers, suspect they belong to an extraterranean civilization (Photo)

Baigong tubes are one of the greatest mysteries of the ancient world. They can be found within a pyramid located on top of Mount Baigong in Qinghai province of northwest China, reports “AlienBlog”, Periscopi broadcast.

The ruined pyramid once had triangular entrances on its three sides, but over time, two of them crashed and were not actually discovered where they might be located. Some doubt that they may be deep inside the mountain.

The only remaining cave houses a complex network of metal tubes, with diameters as large as 1.5 meters and as small as a tooth picker.

Some of the archaeologists who visited the country speculated that the pipes might once have supplied pyramid water. Their theory seems to be supported by a host of iron pipes located on the banks of nearby Lake Toson. These are also available in a variety of length and diameter, some reaching the surface of the water, others buried below.

Deluded by these artifacts abroad, the Beijing Institute of Geology analysed Bagigong tubes using a technique called thermoluminescence. This method allowed them to determine when the pipes were finally subject to high temperatures. The analysis showed that the pipelines should have been drawn up over 150,000 years ago.

And the mystery goes deeper. The analysis conducted at a government-run smelter was unable to determine the exact composition of the pipes. Even though the tubes were made from iron oxid, silicon dioxide, and calcium oxid, they also contained 8% of an unknown material.

There is no easy way to explain this discovery. Human presence in the region may be traced up to 30,000 years ago, but it was mainly made up of nomad tribes. It would be impossible for a primitive society to leave such an advanced structure.

A number of theories have made efforts to explain who could have built these pipes and what purpose they may have served. An advanced but long - forgotten human civilization could have built a cooling object, and the pipes that led to the nearby lake are all that remains.

Interestingly, the water in the lake is salty. Although there is a freshwater lake nearby, there are no pipes leading to it. Why the Need for Seawater?

One possible answer is electrolytes. When an electric current passes through seawater, it breaks water into hydrogen and oxygen. These products are a necessity for every aircraft that operates in this civilization. This particular civilization does not resemble human civilization.

On the other side of the theoretical spectrum, we have some geologists who believe tubes are just an unusual but natural formation.

The fact of the matter is that these are all just theories trying to explain something that simply doesn't match our accepted system of beliefs.

One thing is certain until history is rewritten, improper artificial objects such as baigong tubes have no place in conventional texts. /Periscopi/
