Another piece of evidence besides helium is the magnetic field.
Eric Robert also explained in detail: After rigorous investigations, it has been found that in the past history of the earth, the earth's magnetic poles will rotate once on average about 200,000 years; 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 we were lucky because the geomagnetic pole was stable; but now scientific research shows that the situation is serious.
Eric Robert summed it up this way: Originally once every 200,000 years, it was like a parole; but now the extension of 600,000 years is more like a reprieve.
Eric Robert concluded with passion: “Imagine the consequences of not having a magnetic field, Mars is a living example.
We have urgently extracted various uranium and plutonium isotopes 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 at a depth of 2,900 kilometers.
The nuclear fuel will then be detonated here.
Now, use your imagination.”
A drop of cold sweat flowed down from the tip of Qin Fei's nose.
Qin Fei was frightened when he attended such a top-level gathering for the first time.
Those who can speak publicly on this occasion have definitely gone through the most rigorous scrutiny, and have even been recognized by scientists around the world.
This shows that the earth is really experiencing a "suspension 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 passed and lunch was about to begin, but there was no good solution.
The only reasonably good method should be the "sedimentation method" proposed by an American scientist.
The idea behind this method is that both uranium and plutonium are "heavy elements."
As long as you drill a hole in the weakest crust of the seabed or find a volcanic crater, you can put these elements into it.
These heavy elements will then naturally settle under the influence of gravity, and eventually converge into the Earth's core.
This method should not be too fast.
It should be released in small amounts each time and continuously.
This approach is already being adopted.
But because of the thick crust, everyone is not sure how effective it will be.
It is very risky, but it is the only method at present.
However, before lunch, this issue was temporarily shelved and this discussion was over.
It would be good to have a method for the time being.
After lunch, we started on the second question, the earth’s climate.
This time Qin Fei broke out in a cold sweat again.
He did not expect that the climate problem was also so serious.
Based on long-term observations, scientists have discovered that the climate has actually been changeable in the history of the earth.
Perhaps the first ten years were as warm as spring.
It will be extremely cold for the next thousand years; after repeated verification, scientists have concluded that the era we live in is not normal.
Yes, you heard it right.
This warm era we live in is really abnormal; in the past history, there will be obvious climate changes almost every decade or so, and there will be earth-shaking climate changes every thousand years; In the history of the earth, there are only a few eras that are relatively constant, including the age of the dinosaurs; so the dinosaurs became extinct.
After verification.
The reason why climate change is so dramatic is extremely complex.
The first is the change in gravity; changes in the gravity of the planets in the solar system, as well as the position of the solar system in the universe, etc., will cause the earth's orbit to change uncertainly.
Therefore, the earth's environment is changeable.
Secondly, it is also related to the composition of the atmosphere.
In particular, sulfur dioxide and carbon dioxide concentrations will affect climate change.
The sulfur dioxide emitted by a large volcano will cause the global temperature to drop by one to two degrees, or even cause a larger change; a super volcano eruption can even cause a temperature change of more than 5 degrees Celsius, and the average air condition of the earth is only 14 degrees.
Sulfur dioxide forms water droplets in the atmosphere.
It has a reflective effect and can cool down the earth.
This time the discussion is not very intense, because today's technology is enough to deal with climate change.

Especially after obtaining the "lightning cooling" technology, humans can control the atmospheric temperature through nuclear energy and lightning cooling technology.
It can be said that Qin Fei's contribution is great.
This time, everyone praised Qin Fei again.
Next to discuss is the issue of super volcanoes.
The most representative one here is Yellowstone Volcano Park in the United States.
Fortunately, there has been no eruption in the past five hundred years; but it is also very bad.
After more than five hundred years of accumulation, the Yellowstone volcano has become unstable and has now become the number one threat on the earth.
According to calculations based on existing data, the Yellowstone volcano erupts, its volcanic ash can cover half of the earth, and its exhaust gas can completely change the earth's climate; this is a real super volcano.
When the Yellowstone volcano erupts, there will be no traditional crater.
Instead, the entire earth's crust will collapse directly.
There will be at least 130 kilometers or even more than 220 kilometers of crust collapse.
The hot, high-pressure magma inside the earth will even rush out of the atmosphere.
All the personnel looked heavy.
Although these scientists had discussed this issue more than once, their hearts became heavier every time they discussed it.
If the cooling of the earth's core can be solved slowly, then this super volcano is a sharp sword hanging over the earth and can fall down at any time.
Although the earth's civilization has entered the interstellar age, there is still only one earth in the solar system.
This is the root of earth's civilization and a spiritual holy place.
Once a catastrophic disaster like a super volcano explosion occurs, it will be a tragedy for the entire earth civilization.
However, facing the monster of super volcano, everyone is helpless.
With current technology, earth civilization already has many means to destroy the earth; but it is really powerless to save the earth.
This is the same as killing.
Killing a person is easy, there are countless ways, and there is no need for science at all; but it is much more difficult to save a dying patient, and sometimes it even exceeds the limits of science.
Some scientists have proposed actively detonating volcanoes on a small scale, but this is obviously unrealistic.
The idea is wonderful, but it is not feasible.
Who knows if an entire supervolcano will be detonated in the process.
"Everyone, stop, stop," Long Wenjie shouted loudly, "I have a method here.
It is also a relatively simple, feasible and profitable method.
Do you want to listen to it?"
The glare seemed like a laser, trying to pierce Long Wenjie; suddenly, another "laser" swept towards Qin Fei who was next to Long Wenjie.
Today, Qin Fei did not sit next to Gu Qingyan, but sat next to Long Wenjie.
Apparently some scientists with sharp eyes and minds have discovered this.
"Long Wenjie, I'm sure this is not your idea, otherwise you would have said it a long time ago.
It must be the idea of the little genius Qin Fei again."
The bearded Russian almost pointed at Long Wenjie's nose and shouted. .
Long Wenjie laughed proudly: "You are jealous, haha.
However, this is what Qin Fei thinks, I am a top student at Dragon Soul University.
Although it is also a top ten university, does your Russian Tsarist Academy have such a genius?"
"Hum, tell me, what method?"
