The serious forum has reached its final stage, which is the third stage. Originally, this third stage was only one day or even half a day at most; And this time, because the problem of global warming has been solved, the third phase has a full three days of discussion.

And Qin Fei, a little-known "kid", actually came up with a lightning cooling method, which suddenly made many experts and professors not quiet - I feel a little embarrassed.

Therefore, these scientists are really ready to go crazy, at least to make a certain contribution to the various crises that are about to start to be discussed, and at least to give a feasible approach.

In such an atmosphere, the forum began again; The Secretary-General of the United Nations stepped onto the podium with heavy steps.

"Ladies and gentlemen, this is the heaviest hour again. Every time we discuss these crises, we feel small. Our technology is constantly improving, but the challenges that nature gives us are also constantly escalating.

Or rather, these crises have existed for a long time, and we have not discovered them until today.

But there is a show today, and before I begin, let me announce a good news. Preparations are underway for lightning cooling technology, and in 10 days at the latest, you will see the first global lightning cooling.

As a hero who contributed to the lightning cooling technology, Qin Fei, after overnight discussions, we decided on the first reward. The first reward is that all top scientists are treated: citizens of the planet.

From then on, whether in the United States, in India, in Europe, or in Africa, you have all the rights and interests of local citizens. You don't need to go through the formalities when you enter or leave any country, and the earth has no borders for you. If you are treated unjustly, then the United Nations will intervene directly.

Qin Fei, please come to the stage and let me personally put on the medal for you. ”

The UN Secretary-General personally hung a special medal on Qin Fei's chest; Numerous applause rang out. At this moment, Qin Fei was still a little confused, he was actually treated as a top scientist? And also. In front of all scientists, worn by the UN Secretary-General himself?

Until he walked back to his position, Qin Fei was still a little dazed.

"Well done!" Gu Qingyan took the lead in sending congratulations.

It was only at this time that Qin Fei had the opportunity to observe his medal, a small golden-yellow hard metal card the size of a bank card, on which was a plane map of the earth microcarved, with the location of Huaxia in the center and a red star.

Seeing Qin Fei's appearance, Gu Qingyan suddenly smiled, "Hehe...... Don't look at it. This red star indicates that you are from China. In addition, this medal is not simple. It is not only a medal, but also your world citizen ID card, but also a bank card. All the banks of the Earth civilization will be open to you, and there should be a hundred million dollars in bonuses stored in them.

Congratulations. ”

"Does Teacher Gu have such a medal?" Needless to say, after the surprise, the bear child's true nature was revealed, and Qin Fei began to show off.

gave Qin Fei a blank look before Gu Qingyan turned his head.

The frantic applause ended, and the heavy topic finally began.

The UN Secretary-General's voice was once again filled with heaviness, "The planet is dangerous. The earth is really dangerous. We are now facing many extreme dangers, which will bring devastating disasters to the Earth and the solar system.

These catastrophes do not come from the wars of interstellar civilizations, but from the dangers of the universe itself.

These disasters. We can turn to the higher civilizations for help, but we won't do that unless we have to. First of all, the cost is not necessarily something we can afford; Secondly. Only by solving difficulties and facing difficulties can civilization truly transform. Moths can break through their cocoons and dance, and eagles can soar into the sky. If our earth civilization wants to truly stand at the pinnacle of interstellar civilization, we need to solve these problems alone!

All right. Some of the dangers that are tentatively recognized are as follows, and we discuss them one by one.

The first is the earth itself, the first is that the earth's core is cooled and the magnetic poles are reversed. It should be said that the cooling of the Earth's core and the reversal of the magnetic poles are two manifestations of a crisis. I would like to invite the United Nations Representative for Geological Sciences, geoscientist Eric. Robert explained. ”

This is a little old man, at least that's how Qin Fei sees it, Eric. Robert's whole body seemed to be covered with a layer of mottled marks of wind and sand.

"Hello everyone. Without further ado, let's get straight to the point. "Eric. Robert was very simple, opened the material and began to explain. This is a 3D projection of only about one meter, but it is a cross-sectional view of the earth.

"As we all know, the structure of the Earth is the crust, the upper mantle, the lower mantle, the outer core, the transition layer and the inner core. The structure will not be specific. The Earth's magnetic field is related to the liquid core, and the reversal of the Earth's magnetic field is also a natural phenomenon caused by the Earth's rotation. But that has changed. Let's take a look at our survey reports over the last three decades. ”

Qin Fei, like everyone else, listened carefully, but he listened in a cold sweat; Only by entering this "top science club" do you know how dangerous the planet is.

The report says: The Earth's core is cooling, and it will be cooling faster than ever before. The reason why the earth's core has not cooled after a delay of 4.5 billion years is obviously not entirely because of the large earth, thick crust, thermal insulation of the atmosphere, and slow heat dissipation, otherwise the earth's core would have cooled down 3 billion years ago.

The reason why the earth has not yet cooled is that the core of the earth is actually a large nuclear fission reactor with a diameter of more than 1,000 kilometers, and its main nuclear fuel comes from uranium and plutonium. It is covered with a layer of flowing magma the size of the moon, a layer of molten metal (the hot liquid ion layer) - the source of the magnetic field, because the special mechanism of the formation of the earth's core allows the nuclear reaction to proceed slowly and almost uniformly.

The evidence for this conclusion is helium, after 4.5 billion years of changes in the earth's interior, there can be no obvious helium remnants, and now there is obviously more helium, which can only be a nuclear fission reaction. The discovery of some uranium deposits that remain on the surface of the earth and have been proven to be used shows that the earth's interior is indeed undergoing a violent but steady nuclear fission reaction. It is speculated that the intense pressure, temperature, ion filtration, and dilution inside the earth's crust may have caused the uniform nuclear fission.

Recently, after more than 30 years of observations and calculations, mainly based on helium calculations, the rate of nuclear reactions in the Earth's core is decreasing, and the preliminary estimate is that nuclear fuel has begun to run short. However, because the earth's core cannot be directly observed, it can only obtain an approximate data; According to the available data, the most pessimistic estimate is that the Earth's core will begin to cool in about 1000 years; The most optimistic estimate is that it will last for another 1 million years. The earth is too old, she already has a lifespan of 4.5 billion years, and she is going to rest!

And in addition to helium, there is another piece of evidence.
