The incident of the Japanese secretly discharging nuclear sewage has caused panic among the people in the coastal countries.
Netizen comments: It would be much more reasonable if such a thing that harmed others and was not beneficial to oneself was done by the Japanese.
Quite a few people have also discovered that the Japanese often sneak around doing strange things, for example, they spent 20 years burying 50,000 tons of water at 1,000 meters of ground, and they don't know what it was for.
So did the Japanese hide the water because of the nuclear wastewater, or did they use it for other purposes?
1. The purpose of burying 50,000 tons of water in Japan
In fact, the "Japanese hiding water" happened 20 years ago.
At the end of the 90s of the 20th century, Japan dug a cylindrical stainless steel container with a height of 41.4 meters and a diameter of 39.3 meters in a mine in Gifu Prefecture.
This container looks very unusual, with golden balls densely distributed on it, and the whole device has been named the "Super Kamiokande Detector" by scientists, and the so-called "pure water" is hidden here.
"50,000 tons of pure water" seems bluffing, but in fact it is 50,000 cubic meters, and an Olympic-sized swimming pool is about 2,500 cubic meters, so the amount of water stored underground in Japan is almost the size of 20 swimming pools, so there is nothing to be afraid of.
Netizens asked: Since there is nothing to worry about, why are the Japanese so mysterious? What are these 50,000 tons of pure water used for?
In fact, this is the clever use of Japanese scientists to observe neutrinos.
The so-called neutrino is a type of particle that makes up the world's matter, and is also affectionately called the "cosmic ghost" by scientists.
As the name suggests, neutrinos travel at a speed close to the speed of light, and do not have any chemical reaction with any matter in the air, and are not affected by the earth's electromagnetic force, so they can easily penetrate all matter, and the mass is basically zero.
In other words, neutrinos are powerful beings that cannot be touched, seen, or perceived.
According to a report by Japanese scientists, the human body feels nearly 10 trillion neutrinos every second of the hour.
Even though neutrinos have become so powerful, Japanese scientists have not given up on observation, and the only intermediary that can see neutrinos is to rely on pure water.
More than 20 years ago, Japanese scientists discovered a phenomenon that could capture neutrinos passing through the surface of the water by placing tens of thousands of detectors around ultrapure water.
So, what is the difference between pure water and ultrapure water that can help scientists observe neutrinos and ordinary water?
2. In order to detect the "pure water" of neutrinos
Ordinary people come into contact with dirty water and sewage containing impurities in their daily lives, or purified water that can be drunk, mineral water, etc., and even distilled water has a large number of impurities, and the water used in the laboratory also has a small amount of impurities, and pure water is not the same as the above water.
There are no impurities other than this water molecule, there are no so-called bacteria and viruses, and naturally there are no useful elements that the human body needs.
There is nothing in it except hydrogen atoms and oxygen atoms, so, it is naturally a good thing to use as a chemical experiment.
As a result, Japan placed 50,000 cubic meters of ultrapure water in the "Kamiokande Super Probe", the purpose of which was to capture the appearance of the microcomputer in one fell swoop and conduct follow-up scientific experiments.
In order to observe neutrinos, Japanese scientists have spent enormous efforts.
Observing neutrinos, the requirements for pure water are very high, so they have to use detectors to purify the pure water, trying to make the five tons of water free of trace impurities.
There are many people who do not understand why Japan has invested so much money, and in the midst of doubts that everyone does not understand, the return will quickly answer everything.
In 1996, after the super-probe was put into operation, Japanese scientists quickly captured traces of neutrinos and proved a series of related theories, and the prelude to neutrino astronomy was gradually opened, and the two Japanese scientists also won the Nobel Prize.
For Japanese scientists, although neutrinos cannot be seen or touched, they are a good thing to study earth communication and related theories.
In 2012, American scientists captured the scene of a neutrino passing through a 237-meter-long rock and transmitting the information it carried to a receiver on the back of the rock – such an "absurd" reality that really happened in the laboratory, which is why Japanese scientists are tireless and unwilling to slack off.
Therefore, Japan regards it as a major project, and will put it in a deep mine at a depth of 1,000 meters, so as to achieve the purpose of interfering signals and rays on the ground.
Third, the mainland has also carried out relevant research
So far, Japan has made some progress in the study of neutrinos, but the relevant theories of the mainland have not been carried out on a large scale, not because the mainland does not pay attention to them, but because the continent is not capable of catching up with Japan and the United States at the current level of scientific research.
It was not until 2002 that the Jiangmen Neutrino Laboratory began to collect data, and the neutrino detection facility located more than 700 meters underground gradually appeared.
Today, the United States, Japan, and China have started and continue to detect neutrinos, which is a big event that benefits the world and is also the frontier research of the scientific community.
The "Kamiokande Super Detector", which Japan spent a lot of money to build, will not be easily discarded, which means that they will definitely conduct long-term research on neutrinos.
When the report on Japan's observation of neutrinos was revealed, many netizens in the mainland were enthusiastically discussing: The Japanese have a very respectful attitude towards science, and our country should also learn from Japan.
There are also some netizens who expressed their support in another way: Now that Japan is blatantly discharging nuclear wastewater, who knows what they will do underground. Since people are studying science, the mainland should immediately follow in his footsteps, although it cannot be said to surpass him, at least it should not let him do things in secret.
In fact, such remarks are crooked.
If neutrinos are successfully studied, it will be a major achievement for solving nuclear contamination and nuclear radiation.
In addition, neutrinos can also observe nuclear reactors and control nuclear energy.
If the project is fully prepared and put into operation, the incident of nuclear sewage or the incident of a nuclear reactor can be further controlled by manpower.
For many Chinese people, Japan is not too friendly to China.
Putting aside historical factors, in recent years, Japan's frequent actions against China have also aroused the opposition of many netizens, so whether it is in Japan's scientific research, military, or political circles, any slightest disturbance will arouse the sensitive nerves of the Chinese people.
Therefore, netizens believe that the Japanese cannot be allowed to grasp the technology tightly in their hands, otherwise, they may be a big circle ahead of China in the future.
Some people arrogantly said: Even if you want to benefit the whole world, you have to let China come.
