Many people know about the crystal skull from the movie raiders of the lost ark and the Kingdom of Crystal Skull. In the movie, the crystal skull is the skull of a mysterious alien who created ancient human civilization. Although in reality, archaeologists are not sure that the crystal skull comes from the body of an alien, the previous 13 mysterious crystal skull is really confusing. Most of them appear in Honduras, Mexico and other places in Central America, and people associate them with the mysterious Mayan civilization and pyramids. The crystal skull is all made of high-purity transparent crystal, and there are no obvious tool cutting marks on it. They are made without considering the natural axis of crystal at all, which is also very difficult in today's technology. If the laser is injected into the nasal cavity of the crystal skull, the skull will glow and the surface will show the prism effect of the skull.
In 2008, a research team composed of British and American scientists used electron microscope and X-ray crystallization technology to examine the crystal skulls collected by the British Museum and the Smithsonian Museum. A detailed analysis of the skull surface shows that there are tiny rotating scratches near the eyes, teeth and skull. Obviously, this cutting and polishing technology originated from a kind of jewelry processing equipment called "rotating wheel", but the ancient Mayans did not master this processing technology, and there was no such tool in the American continent before Columbus. The researchers concluded that these crystal skulls were processed and manufactured in Europe, and the material was Brazilian colorless crystal. These crystal skulls were probably made and sold to collectors as mysterious relics of the ancient Mayan Aztecs. At present, many museums have cancelled the display of crystal skulls, which makes people doubt its source and think it has no archaeological research value.
Interesting fact: 13 mysterious crystal skulls are scattered all over the world, and the most famous one is the "doomsday skull". 1924, this crystal skull was held by Anna Mitchell-Hedges, who inherited it from her adoptive father, British adventure writer F·A· Mitchell-Haigis. According to Anna, the history of this crystal skull can be traced back to 3600 years ago. The eyes of the skull can emit blue light. Put it next to the computer, causing the computer hard disk to "crash" many times. At present, this crystal skull has never been tested by any experiment, because the current owner does not allow it.
2. The mystery of shark virgin childbirth
200 1, Henry Dolly Zoo, Nebraska, USA, a hammerhead shark gave birth to a baby shark. It is difficult for scientists to understand that this female shark and three female sharks live in an aquarium. They have lived in the aquarium for three years. How did she give birth to a baby shark without a male shark mating with her?
Some scientists believe that one of the reasons for this phenomenon is that female sharks can store female sharks' sperm for fertilization, while others believe that sharks can achieve asexual reproduction through a rare parthenogenetic method (without direct fertilization of sperm).
3. The unknown boy in Titanic
A few days after the sinking of the Titanic, rescuers found the body of a boy in the North Atlantic, but when he was buried in Nova Scotia, Canada, his identity was not confirmed, so he had to mark "Unknown Boy" on the tombstone. In 200 1 year, researchers from the University of Lakeside, Ontario, Canada approved the excavation and analysis of the boy's body. By consulting the passenger list of Titanic, the identity of the unknown boy was reduced to one of four children-Gustave Paulson, enoch Panula, Eugene Rice and Sidney Goodwin. At first, people inferred that the boy's body was enoch Panula, but in 2000,
4, tube eye fish transparent head
This tube-eyed fish, which lives at a depth of 2500 meters, has a strange appearance. Its tubular eyes can collect light from the deep sea, but scientists are puzzled by the function of this eye structure. This tubular eye structure can only see the immediate target. How does it prey and survive in the deep sea environment?
In March this year, scientists used remote operating instruments to study the tube-eyed fish at a depth of 600-800 meters on the seabed. They discovered an unknown fact before-its head is transparent and its eyes can rotate freely. This transparent head structure broadens its vision, and it can also see the prey on its head. It is reported that the tube-eyed fish was first discovered in 1939, but because the fish caught by fishing boats came from different deep waters, this transparent fish died before it was discovered in time.
Interesting fact: from the picture, people usually think that the two small holes in the front of its head are eyes, but they are not its eyes. Its eyes are green and round, at the front of its head. Their eyes are protected by a circle of transparent substances filled with liquid, which even cover their whole heads.
5. "New England Black Day"
On May 1780 and 19, an unusual "black sun" was observed in "New England" and parts of Canada. Because the scientific knowledge of that era was very backward, many people in Britain associated this phenomenon with religious belief. Even today, "New England Black Day" is still considered by many people to be related to supernatural phenomena. It is reported that New England, also known as "New England", is located in the northeast corner of the continental United States, bordering the Atlantic Ocean and Canada.
6. Sound effects of Epidollas Theatre.
Epidolls Theatre, located near Athens, Greece, was built at the end of 4th century BC and is one of the well-preserved ancient theaters. Even more than two thousand years ago, this theater still had very good acoustics. Without public address equipment, the actor's performance was in the theater of10.5 million, and all the audience could hear it clearly. In order to confirm the acoustic effect of the theater, the researchers of the research team scattered around the theater, trying to test the intensity of the sound coming from the center of the theater, trying to reveal why the theater with such professional acoustic effect can still be built under the harsh conditions of ancient buildings. This has been a mystery for many years, and some researchers once thought that it was probably the airflow that promoted the spread of sound.
7. "The face of Mars"
Scientists are deeply attracted by the peculiar terrain in the Szidonia region of Mars. Some hills in this area look very much like a human face, and some scientists speculate that this may be the masterpiece of intelligent life on Mars. This space photo of "Mars face" was first taken by Viking 1 in 975. Other photos include 1976' s terrain of Pingdingshan in Szidonia. It looks like a human face from the first photo, but the photos taken later are completely different. Scientists believe that this may be due to the different angles of sunlight. This discovery has attracted the attention of intelligent life research institutions outside the earth. Some researchers believe that this kind of face topography may confirm the existence of the long-lost Martian civilization. But most scientists still insist that the "Martian face" is only formed by different visual effects.
8. Translate hieroglyphics of ancient clay tablets and slates.
2 150 years ago, a circular clay tablet was found in Iraq, which was Nineveh, the capital of ancient Assyria (an ancient country in the Tigris River basin in southwest Asia). On stone tablets, Sumerians used hieroglyphics to describe starry sky images and some ancient characters. For decades, scientists have not explained the contents of this circular clay monument.
