The unsolved mysteries of the world are natural, astronomical and historical phenomena that people can't explain with existing scientific and technological means or according to normal thinking logic and reasoning methods.

Since the 199s, all kinds of unsolved mysteries have been very popular in China. In the face of money, many unsolved mysteries have also become unsolved, misleading everyone. Let's take stock of a few mysteries for everyone.

1. Bermuda Triangle

Rumor: Bermuda Triangle, also known as Devil's Triangle. Located in the southeast of Florida Peninsula in North America, it is an eastern Atlantic triangle formed by the three-point connection of Bermuda, Miami in the United States and San Juan in Puerto Rico. It is said that Bermuda is as horrible as an underwater hell. Anyone who has been to this place, whether human or any living thing, has been swallowed by this "devil" and disappeared without a trace.

Data show that since 188, thousands of people have died here, hundreds of planes have disappeared and more than 2 ships have been lost. There are even people who have seen ghost ships, and there has been a phenomenon of magnetic imbalance. Some people think that the connection here is through time tunnel.

the truth: the Bermuda triangle is the most dangerous sea area in the world, and it is not even in the top ten, but it is the most famous. Most of the traffic accidents really exist, but a few of them are fabricated, and some accidents are exaggerated and mystified; There are often hurricanes or thunderstorms in the waters near Bermuda, which is a great threat to maritime traffic. Before GPS was born, computers were not widely used, airplanes were still using propellers, and weather forecasts were mostly based on guesswork. From the early 19th century to the first half of the 2th century, it was not inconceivable that there were plane and ship crashes in Bermuda Triangle. Bermuda has also become a famous tourist destination.

Attachment: WWF has made statistics on the ranking of the places with high incidence of shipping accidents in the world. The most prone areas are the Sea of Japan, the Mediterranean Sea, the Persian Gulf and other places, while Bermuda is not even among the top ten.

2. Crystal Skull

Rumor: Legend has it that there are 13 crystal skulls in the world, which are the same size as human skulls. The chin can move freely, talk and sing, and it also records the survival and beginning of human beings, and even helps human beings solve the mystery of cosmic life and predict the secrets of human past and future. As long as the 13 crystal skulls are gathered together, all kinds of supernatural things will be produced.

In 1927, Haggis, a British explorer and a member of the Mayan Cultural Committee of the British Museum, discovered a crystal skull in the ruins of an abandoned ancient Mayan city in Central America and publicized it.

Reality: Until 28, a research team composed of scientists from Britain and the United States used the latest modern technology to test the crystal skull collected in the museum. The crystal skull was developed by grinding wheels in the 17th and 18th centuries.

Some conspiracy theorists believe that scientists know the real secret of the crystal skull, but for some reason, they need to hide the truth from the public, so they fabricate the statement that the crystal skull is a fake. What do you think? )

3. The front and back of the moon are the same

Legend has it that the front and back of the moon are the same.

the truth: on earth, we can only see one side of the moon. The moon's rotation is basically the same as that of period of revolution, and it has been tidal locking by the earth, so it belongs to the tidal gate type, with only one side always facing the earth.

4. Loch Ness Monster

Legend: Loch Ness, the northernmost part of the British Isles, is located in the Grand Canyon of the Scottish Plateau and is the third largest freshwater lake in Britain. Legend has it that there is a water monster similar to plesiosaur in the lake, which has a neck longer than giraffe and a body larger than elephant. It will knock over boats, attack humans and eat livestock by the river. Some rich people even offered a reward of 2, pounds to capture the Loch Ness monster, and some people took photos of the monster-which became the most powerful evidence to prove the existence of the Loch Ness monster.

Truth: In 1933, bertram Mills, the circus owner who was touring the Loch Ness area in England, happened to know the legend and made a public announcement for commercial purposes, offering a reward of 2, pounds for catching the Loch Ness monster, which made him famous. In 1994, the 9-year-old man admitted that the water monster in the photo was forged by himself and his stepfather; According to the photo provided by the old man, the newspaper deliberately cut out the blank around the photo, and the change of the contrast led to the change of the "neck" from 3 cm long to 3 m long.

5. Nuclear reactor 21 years ago

Legend: In 1972, France imported some uranium ore from Gabon, Africa, and French engineers found that the average concentration of uranium 235 was much lower than the normal concentration of uranium 235.

after a long period of exploration, experts concluded that there is a very old atomic reactor in Oklo. This atomic reactor consists of about 5 tons of uranium ore in six regions, and its output power is about 1 kilowatts. The mineralization age of this mine was about 2 billion years ago, and the atomic reactor began to operate not long after mineralization, and the operation time was as long as 5, years.

Reality: After research, it is found that these so-called nuclear reactors have no artificial signs at all, and there are no shaped reactors. These uranium ores are irregularly scattered in some places, and nuclear fission reactions have taken place under a series of coincidental natural conditions. In particular, the action of water and oxygen permeates into underground ore, which makes uranium react and release heat. When the water is evaporated, it will stop again and again for a long time. Finally, boron and lithium rich in veins absorb neutrons, which stops the nuclear reaction.
