Science has always been an important means to lead us to progress, not only changing our way of life, but even making our motherland richer and stronger.
But you can't believe that there have been five major lies in the history of science, and there are people who believe it until now.
A 2-billion-year-old nuclear reactor
In 1972, Buzguet, who worked at the Pierre Rath nuclear fuel reprocessing plant in France, noticed that uranium ore from Oklo was of low quality.
Uranium is a radioactive element found in nature and is an important material used in the production of nuclear fuel.
Therefore, this matter has also attracted the attention of the French Atomic Energy Commission, after all, nuclear energy is a big deal, and any raw materials must be regulated.
At first, the French atomic energy personnel thought that someone had stolen the ore from the factory and sold it quietly, but no matter how they investigated, they did not find any problems at any stage.
So the IAEA staff can only focus on the ore.
After careful study, scientists have discovered that there is a surprising secret hidden in the Oklo uranium mine – the deposit has once hosted as many as 15 natural nuclear reactors.
In order to find out the truth, the scientists made isotopic measurements of the samples, and the results showed that the concentration of uranium-235 isotopes in the uranium ore was abnormally enriched and reached a high level of 3%, according to the analysis of the uranium ore by scientists.
Moreover, scientists have also found a large number of decay products produced by nuclear fission, and according to scientists' calculations of the products, it has been proved that there were many nuclear chain reactions here 2 billion years ago.
Gears from 400 million years ago
On March 12, 2012, Russian geologists discovered a unique rock while on the Kamchatka Peninsula.
The discovery of a large number of mechanical gear-like devices embedded in the rock, beautifully made in a way reminiscent of modern industrial products, immediately aroused great interest in the scientific community.
Through the identification and analysis of the rock, the stone is preliminarily considered to have been formed in the Devonian period about 400 million years ago.
At that time, there were no Homo sapiens on Earth, and the truth behind the objects in the rocks was unclear whether they were formed naturally or from some unknown ancient civilization.
Some experts believe that its delicate structure indicates the existence of some kind of ancient high-tech civilization. But upon further investigation, a surprising fact was revealed.
It turns out that these fossils, which resemble mechanical parts, actually originate from an ancient sea creature that has existed for 500 million years, the sea lily. Sea lilies are widely distributed in shallow areas and are often epiphytic on corals and rocks. The whole is scaffold-shaped, and the bottom is globular shaped.
Millions of years ago, the sediments of these sea lilies were buried by sediments and gradually petrified under the action of high temperatures.
The tectonic plates eventually carried them to the upper part of the land, where they became part of the rock, which has been preserved to this day.
Astronaut stone carving
In a 16th-century Gothic church in Spain, there is a stone sculpture of a curious figure that has been stunning for hundreds of years.
The statue depicts a figure dressed in a space-like costume, which not only has novel facial features, but is also very different from the mainstream sculptural style of the time.
Considering the impression that humans in the 16th century did not know about the concept of astronautics, the existence of such a statue is really incredible.
For a time, it became the focus of many history buffs. There has been speculation that this may be some kind of foreshadowing or a sign from another world. And to the right of the astronaut's stone sculpture is a lion eating ice cream, which adds some mystery to it.
Who carved this stone sculpture? After careful investigation by scientists, the truth came to the surface.
It turned out that this was an ingenious work of the church designers back then.
During the church's routine maintenance in 1992, they deliberately added a few elements to the sculpture that did not match the old style, just to add some interest and modernity.
Shapes such as astronauts and lions eating ice cream are the imagination and craftsmanship of the designers. They perfectly blend the old and heavy Gothic architecture with a futuristic feel.
Crystal skulls
A quirky object called the "Crystal Skull" has long been a hot topic of public discussion.
It is clear throughout, showing a high level of craftsmanship, and has attracted the interest of countless explorers and archaeology enthusiasts.
There are also various mysterious legends about the origin and purpose of this skull. One of the most striking is that it contains some kind of extraterrestrial intelligence waiting to be decoded, which adds to the mysterious value of the skull itself.
However, in the subsequent scientific testing, the truth about the crystal skull gradually emerged.
Both the 2005 appraisal and the subsequent 2008 study by the French Museum suggest that the skull is likely to have been made in the 19th century, rather than a relic of the Mayan civilization, and there is no physical evidence that it contains any coded information.
Scientists have found a large number of cut marks on the skull, which highly coincide with the techniques used by Idar-Oberstein, one of Germany's famous jewelry-processing regions at the time, where craftsmen mastered the unique craft of carving ordinary glass materials into skulls.
Facts speak louder than words, and this discovery corrects a long-standing misunderstanding by the public, and reminds us of the scientific attitude that still needs to be skeptical and verified when interpreting historical sites. Fanaticism and prejudice often lead us astray.
Ancient Egyptian aircraft
Archaeologists in the 19th century have discovered a unique wooden model in an ancient tomb in Egypt.
Its wings are streamlined, and the whole is in the shape of a bird, very similar to the shape of a modern airplane.
But at first this model named "Wood Bird" did not attract attention, and it was not until the creation of airplanes in the last century that they were brought out for discussion again.
And it's not just the bird models, some of the murals also depict helicopters, which raises the idea of some kind of lost ancient aviation technology.
Indeed, with the complexity of structures such as the pyramids of ancient Egypt, this imagination is not unfounded.
Egyptian civilization has always been mysterious and unpredictable, and its unique pyramid and tomb culture has always been a hot topic of public discussion.
A wooden model found in his tomb in recent years has added to the mystery.
Known as the "Wood Bird", this model has a biplane streamlined body that bears a striking resemblance to modern aircraft. Does this mean that the ancient Egyptians mastered some kind of avant-garde aviation technology, or is it simply an artistic fiction or coincidence?
Later, after careful investigation by archaeological experts, the truth of the wooden bird model was unraveled.
It turned out to be just a very unique old toy, not an "airplane" or a "spacecraft" as people had guessed.
After comparative research, archaeologists found that this wooden bird model is very similar to ancient Chinese children's flying toys such as paper kites and kites, and they all belong to decorative and carved folk crafts, and do not conform to the aerodynamic principle of real flight. The reason why it can "fly" in the wind tunnel is completely dependent on the wind power, and there is no power of its own.
In addition, the images of suspected "helicopters" in some of the pictures are also deliberately or fabricated by later generations.
The ancient Egyptian "wood bird" 4,000 years ago suddenly appeared in the sky over Yangpu?!
