Scientists speculate that the Greek bottomless pit may lead directly to the center of the earth. Is there a secret hidden in it?

Although human beings know more and more about the earth, there are two places on the earth that human beings know little about, one is the ocean and the other is the interior of the earth. 7 1% of the earth's surface is ocean, and the deepest part of the ocean is tens of thousands of meters. There are many kinds of creatures in the ocean and precious resources, such as oil and combustible ice, but there are still many unknown and mysterious things in the ocean that human beings don't know. With the development of human science and technology, the depth of the ocean we can dive into is also increasing, and we know more about the ocean, and we have discovered many secrets of the ocean.

What is the most mysterious and difficult place to explore on earth? It must be inside the earth, a blind spot that humans can't go deep into and satellites can't detect. At most, some electromagnetic wave technology can be used to explore the interior of the earth, but this kind of detection can only be understood very limited. If we really want to explore the interior of the earth, we still need to be able to go deep into it.

But it is impossible to drill deep into the earth with current human technology. The world-famous ultra-deep drilling in Kola took 20 years to drill1more than 2000 meters. This depth has never been far from the outermost skin of the earth, let alone to the center of the earth. The average diameter of the earth is 12756 km. The temperature inside the earth also increases with the depth. When the temperature reaches more than 5000 degrees Celsius, the drill bit will melt and soften, and it can't go down any more.

Therefore, it is impossible for human beings to drill into the earth's interior now, but maybe they can drill into the center of the earth until there is a more powerful high-temperature resistant material in the future, which can resist the high temperature environment inside the earth. In addition to this technology of drilling holes into the earth's interior, scientists believe that there may be natural passages leading to the deep center of the earth.

I believe many people have heard of the bottomless pit. The so-called bottomless pit generally refers to a hole or abyss whose bottom cannot be detected, and the water or other substances that enter may not be recovered. There are indeed many such bottomless pits on the earth. For example, there is a bottomless pit in Shihaidong Township, Xingwen County, Sichuan Province, China, with a long diameter of 650m, a short diameter of 490m and a depth of 208m. Whether it's a downpour or a gathering of mountains and rivers, there is no water at the bottom. Usually, all kinds of detection methods are used, and the remains of water that disappeared in the funnel can always be found again, and will always reappear on the ground near or far.

Some ancient books in China have repeatedly mentioned that there is an unfathomable bottomless pit overseas. Liezi? "Tang Wen" records: "East of the Bohai Sea, there is a big valley, which is bottomless and named Hui Gui." People like Tianhe and Han should be careful not to increase or decrease. "

Although there are many bottomless pits on the earth, the water or objects that enter these bottomless pits are traceable and can always be found somewhere on the ground. However, there is a mysterious bottomless pit in Greek waters, which is different from other bottomless pits. The seawater flowing into this bottomless pit never appeared on the ground again.

The bottomless pit in Greece is close to the sea, and a lot of seawater will be poured in at high tide. About 1 10,000 tons of seawater will flow into the bottomless pit every day, but the seawater that has flowed in has not reappeared in other sea areas. Such a mysterious bottomless pit naturally attracted the attention of scientists. In order to reveal its secret, in 1958, the United States sent an expedition to explore this bottomless pit. The expert dissolved a durable dark dye in seawater and poured it into the hole with the seawater. Then observe the nearby sea surface and various rivers and lakes, trying to find these dyes, but the result is disappointing, and people have not found colored seawater.

Scientists never give up. A few years later, they started a new experiment. This time, they made a rose-colored plastic particle. This is a kind of plastic particle, slightly lighter than water, which can float in water without sinking and will not be dissolved by water. They threw 1300 kg, a substance with a special mission, into the tumbling sea water.
