Another piece of evidence besides helium is the magnetic field. Eric. Robert also explained in detail:

After rigorous investigation, in the past history of the earth, the average is about 200,000 years, and the earth's magnetic poles will be reversed once; Although there will be fluctuations, they will not be too large. However, the most recent magnetic pole rotation was 800,000 years ago.

In the past, people thought that the geomagnetic pole was stable and we were lucky; But now scientific research is showing that the situation is serious.

Eric. Robert summed it up like this: Originally, once every 200,000 years, it seemed to be parole; And now it is extended by 600,000 years, which is more like a reprieve!

Eric. Robert concludes with emotion: "Imagine the consequences of not having a magnetic field, Mars is a living example."

We have urgently extracted various isotopes of uranium and plutonium in space, but unfortunately, we do not yet have the ability to send these things into the Earth's core.

With current technology, we can only send these elements into the lower mantle layer at a depth of 2,900 kilometers. And then the nuclear fuel will be detonated here.

Now, let your ideas run wild! ”

Let's ...... A drop of cold sweat ran down the tip of Qin Fei's nose. The first time he participated in such a top-level party, Qin Fei was frightened. Those who can speak publicly on this occasion have definitely undergone the strictest scrutiny, and have even won the approval of scientists around the world. This shows that the earth is really experiencing a "reprieve of death".

Although there is a lot of news circulating on the Internet, such specific data will not be made public.

The scientists had a heated discussion, but half a day had passed, and seeing that lunch was about to start, there was no good way. The only good method should be the "sedimentation method" proposed by an American scientist.

The idea is that both uranium and plutonium are "heavy elements". All you need to do is drill a hole in the weakest crust of the ocean floor, or find a crater, and you can throw these elements into it. These heavy elements then settle naturally under the force of gravity and eventually converge into the Earth's core.

This method should not be too fast, but should be released in small quantities at a time, and continuously. This method is already being used, but because of the thick crust of the earth, people are not sure how effective it will be - it's risky! But that's the only way to do it at the moment.

But before lunch. The issue has been put on hold for the time being - and with this discussion over, it would be nice to have an approach for the time being.

After lunch, the second question begins, the Earth's climate. This time, Qin Fei broke out in a cold sweat again. I didn't expect the climate problem to be so serious.

According to long-term observations, scientists have found that in the history of the earth, the climate is actually changeable, perhaps the first ten years are as warm as spring, and the next thousand years are extremely cold; After repeated research. Scientists have come to the conclusion that we live in an era that is not normal!

Yes, you heard it right! The warm era we live in is really abnormal; In the past, there was a more obvious climate change almost every decade or so, and there was a chance of earth-shaking climate change every thousand years; There are only a few epochs in Earth's history that are relatively constant, including the age of the dinosaurs; So the dinosaurs became extinct.

It has been proven that the reason why climate change is so drastic is extremely complex.

The first is the change in gravity; Changes in the gravitational attraction of the planets of the solar system, as well as the position of the solar system in the universe. will lead to uncertain changes in the Earth's orbit. So, the Earth's environment is changeable.

Secondly, it is also related to the composition of the atmosphere, especially sulfur dioxide and carbon dioxide concentrations, which will affect climate change. Sulphur dioxide from a large volcano can cause global temperatures to drop by one to two degrees, or even more. Supervolcano eruptions can even cause temperature changes of more than 5 degrees Celsius – and the average planet is only 14 degrees Celsius. (Sulfur dioxide layers in the atmosphere to form water droplets, which reflect light and cool the planet.) ）

This time the discussion was less intense, because today's technology is more than enough to cope with climate change, especially with the advent of "lightning cooling" technology. Humans can then regulate the temperature of the atmosphere through nuclear power and lightning cooling technology. It can be said that Qin Fei's contribution is great. This time, everyone praised Qin Fei again.

The next step is to talk about supervolcanoes. And the most representative of this is the Yellowstone volcano (park) in the United States.

Thankfully, there has been no outbreak in the past 500 years; But it's also bad. After more than 500 years of accumulation, the Yellowstone volcano has begun to unstabilize and is now the number one threat on the planet.

According to the available data, the eruption of the Yellowstone volcano can cover half of the world with its ash and its exhaust gases can completely change the earth's climate; This is a real supervolcano. When Yellowstone erupts, there will be no traditional craters. Instead, the entire earth's crust will collapse directly, and there will be at least 130 kilometers or even more than 220 kilometers of crustal collapse, and the hot high-pressure magma in the earth's interior will even break out of the atmosphere.

All the personnel had heavy faces, and although the scientists had discussed the issue more than once, each time they discussed it, their hearts were heavy. If the cooling of the Earth's core can be solved slowly, then this supervolcano is a sword hanging over the Earth, which can fall down at any time.

Although the earth civilization has been in the interstellar era, there is still only one earth in the solar system, which is the 'root' of the earth civilization and the holy land of the spirit. Once the catastrophe of a supervolcano explosion really occurs, it will be a tragedy for the entire civilization of the earth.

However, in the face of the monster of the supervolcano, everyone is helpless. With current technology, the earth civilization already has many means to destroy the earth; But if you want to save the planet, you really can't do it.

It's the same as killing, killing a person is simple, there are countless ways, and there is no need for 'science' at all, but saving a dying patient is much more difficult, sometimes even beyond the limits of science.

Some scientists have proposed to take the initiative to detonate volcanoes in a small area; But it's obviously unrealistic - it's a wonderful idea, but it's not feasible. Who knows if the entire supervolcano will be detonated in the process.

"Guys, stop, stop!" Long Wenjie roared loudly, "I have a solution here, which is also a relatively simple and feasible way, and it is also profitable, do you want to listen to it?" ”

Swish...... A piece of vision seems to be a laser, trying to pierce Long Wenjie; Suddenly, another "laser" swept towards Qin Fei next to Long Wenjie - today Qin Fei did not sit next to Gu Qingyan, but sat next to Long Wenjie! Apparently some discerning scientists have discovered this.

"Long Wenjie, I'm sure this is not your idea, otherwise you would have said it a long time ago. It's the idea of this little genius of Qin Fei again! The bearded man in Russia almost pointed at Long Wenjie's nose and yelled.

Long Wenjie laughed proudly: "You are jealous!" Ha ha. However, it's Qin Fei's idea, I'm a top student of Dragon Soul University. Although it is also ten universities, do you have such a genius in your Russian Tsarist Academy? ”

"Humph! Tell me, what way? ”
