Scientists have named them as Oopart – the 150,000-year-old pipes found in China. Oopart stands for out of place artifact and there is absolutely no scarcity of Oopart in our world. In Quinghai province of China, close to Mount Baigong are 3 caves that have been found to be filled with pipes that have been dated by Beijing Institute of Geology to be 150,000 years old, says Skeptoid.com’s Brian Dunning.
Upon inspection (investigation started in 2002) scientists have found that the pipes not only lead to a nearby salt-water lake but are also present on the lake shore as well as on the lake bed. These iron rods are available in various sizes and some of them are smaller than a standard toothpick.
Carbon dating was not used for dating those pipes. The scientists used a technique known as thermoluminescence. This technique determines the duration for which a particular crystalline mineral was exposed to heat or sunlight. Weirdly enough, the area where these pipes have been discovered was previously known to have been inhabited for only last 30,000 years and that within this timeline, the only humans known to have inhabited the place were people with nomadic lifestyle and hence, the possibility of those people leaving behind pipes is quite out of the scene.
So, how did the pipes come? Who made them? What are the 150,000-year-old pipes made of? Of these three questions only the last one has been properly and partially answered. The pipes were examined and according to the local Delingha government’s publicity department, the 92% of the pipes composed of calcium oxide, ferric oxide and silicon oxide while the remaining 8% could not be identified.
The identified portions of the pipes can be easily explained by modern science at our disposal. Iron, after a long time of interaction with sandstones lead to the production of calcium oxide and silicon oxide. This fact alone is enough to increase the intensity of mystery because it screams out loud that the iron pipes have been out there for very very long time, says Liu Shaolin – the engineer who was given the task of analyzing the pipes.
