7 historical mysteries seem to be impossible to solve forever, finally have the answer

History is an area that contains many mysteries, because we cannot verify past events by seeing the ears, but only through traces, documents, and speculation. half.

However with technological advances, people have gradually deciphered the historical mysteries that seem to never be solved. Such as the mystery in the following list.

1. The mysterious disappearance of the Nazca civilization

Nazca is the name of a plateau in Peru, famous for its strange giant paintings. There are up to 300 paintings here with many different strange motifs.

In the past, many people thought that aliens were the authors of these paintings. But then, science confirmed that they were drawn by humans, dating back to the Nazca culture period between 200 BC and 600. The Nazca used them as a means of communicating with the gods. .

However, the disappearance of the Nazca civilization left a huge question in the archaeological community. Why did they disappear, after leaving countless such confusing pictures? Until recently, scientists from Cambridge University had discovered the reason: they had to leave this area due to excessive drought and deforestation .

2. Secrets hidden underground of the Easter Island statues

Easter Island is too famous for the head statues (called Moai ). One thing before, people thought that these statues were just pure human heads. It was only when the legendary explorer Thor Heyerdahl came to hand that everything was clarified.

Heyerdahl was the first person to conduct research on the island, and he discovered that Moai statues actually contained the body . In addition, he proved that the statues were created by very ordinary tools, existing in human society at that time, not any supernatural forces that worked.

3. Whale cemetery in Chile

In Chile's Atacama Desert, a graveyard is found that contains a lot of whale bones.

Nobody knows why one of the planet's driest deserts has whales there, but so much that it looks like there's a mass suicide. But later, they discovered that the remains here do not come from the same period.

In it, the oldest whale is 20,000 years ago - the time when the desert is still the sea. The cause of death is thought to be an explosion of toxic algae, creating a phenomenon of red tide that causes organisms to die massively.

4. The first computer from the time of . Ancient Greece?

When did you think the first computer was born? In the 20th century?

Right about that! But for a very long time, scientists thought that the Antikythera machine dating back to 80-50 BC was actually the first computer in the world. It was found at the ruins of a shipwreck, in a state of rotting wood, and metal parts rusted.

It was not until 2016 that science learned that they were mistaken for a report on the actual function of this machine.Turns out, it's a device used to navigate. However, it is still a big discovery, when such a sophisticated device has existed for a long time. Because of that, the same mechanism of positioning must take place 1,000 years later.

5. The head of Bosham

The head Bosham (Bosham Head) is one of the best examples of how science and technology really helped archaeologists.

This is a statue found in Bosham (England) in 1800, but in an extremely bad condition and difficult to identify. It wasn't until 2013, thanks to laser technology, that scientists identified this head as belonging to a statue depicting the Roman emperor Trajan .

6. The walking stones in Death Valley

Not only will the name of the horror, but anyone coming to "Death Valley" (California, USA) feel shuddered by a bizarre phenomenon. It is the rocks here that tend to teleport themselves even though no one touches them, just like the "on" person has.

But with science, everything has a reasonable explanation. According to Dr. Ralph Lorenz from Johns Hopkins University, everything is due to the temperature difference. In winter, there is a layer of ice formed on the surface of the rock. The melting ice with the impact of the wind has caused the rocks here to gradually move without anyone touching.

7. Helicopter in Pharaoh's tomb

The walls inside pharaoh Seti I's tomb from more than 1300 years BC have very strange paintings. From many angles, they look like a helicopter, airplane, even tanks and submarines.

When it came to finding these engravings, archaeologists were really tumultuous. Even some people have truly believed that ancient Egyptians had the ability to prophesy, or possessed a greater civilization than we thought.

But the truth of course cannot be "virtual" like that. In 2010, an archaeologist confirmed that the picture was actually the name of Pharaoh Seti I and his son pharaoh Ramesses II.

Ramesses II's name was engraved on his father's name after his death. It's just by chance that they look like helicopters and some other modern means of the day, mainly because the brain wants to feel them like that.
