Scientists have discovered a peculiar phenomenon: the Earth's magnetic field is slowly disappearing.
What does this mean? The most serious end of the disappearance of the Earth's magnetic field is that the Earth's organisms are extinct, and the Earth becomes the second Mars!
Scientists say the strength of the Earth's magnetic field has been reduced by 9 percentage points compared to the original. And with the passage of time, the Earth's magnetic field will slowly disappear in the future, and eventually the Earth will become a waste star due to the lack of magnetic field protection, not to mention the creatures living on the Earth.
Is the Earth's magnetic field really that important to living things?
Changes in the Earth's magnetic field
The existence of the earth's magnetic field greatly facilitates people's lives and also points out the direction for the earth's creatures, such as the compass can help us discern the direction at sea, can help the pigeons find their way home. In recent years, however, scientists have found that some pigeons seem to be lost and can't find their way.
At first, scientists thought that there was a problem with the pigeons themselves, but after confirming that the pigeons were in good condition, they found that the original problem was the Earth's magnetic field, and there were two problems with the Earth's magnetic field, one was that the magnetic field strength was weakening, and the other was that the magnetic field was deflected.
The magnetic field strength is reduced
European scientists found that the strength of the Earth's magnetic field has gradually decreased, from 24,000 na teslas in 1970 to 22,000 na teslas, a decline of 9%, at this rate, after more than 500 years, the earth's magnetic field will completely disappear, when the earth will be directly exposed to the intrusion of the solar wind, and the life of the earth will end.
In fact, another function of the Earth's magnetic field is to deflect the solar wind, the solar wind comes from the supersonic and other electron streams emitted from the upper layer of the sun, which will continue to be emitted outwards, attacking the planets of the solar system, mainly taking away the atmosphere of the planet, whenever the solar wind reaches the earth, it will be interfered with by the earth's magnetic field, deflection, and protect the atmosphere. Without a magnetic field, the Earth's atmosphere would have ceased to exist long ago.
The magnetic field is deflected
In addition, scientists have found that the Earth's magnetic field has been deflected and is deflecting southward at a speed of 48 km/year, and has now gone nearly 2300 km. In fact, the earth's magnetic field deflection is already a normalized situation, according to statistics, the earth's magnetic field will appear every 250,000 magnetic poles upside down, and the last flip was 780,000 years ago, each flip will bring very serious damage to the earth.
After the magnetic pole is flipped, the lives of humans and animals will be affected, and the most terrifying thing is that the solar radiation directly hits the earth, and many organisms will die, which is no less than a biological mass extinction.
How to prevent it
In the face of such difficulties in the future, how should we prevent it?
I want to use human means to try to compete with the entire solar system, and even the universe, it is simply a fool's dream, some people say that the magnetic field has disappeared, then build an artificial magnetic field, the magnetic pole is deflected, then it is turned over.
It is simple to say, but it is difficult to do, for example, to artificially adjust the magnetic pole back, you need two large magnets, one at the south pole, the other at the north pole, adjust the angle, yes, the magnetic pole is located in the center of the earth, and the angle of the offset is all made up. But where are we going to find such a big magnet?
I think if Earth does get to that point, moving to other planets might be relatively easier to achieve.
Habitable planet
Human beings have been looking for a planet suitable for human habitation over the years, and I think scientists have found more and more factual evidence about the future of the earth, and they want to quickly find a planet to continue human civilization. The planets that humans explore the most are the moon and Mars, and the moon has been clearly a planet that is not suitable for human habitation, so what about Mars?
Mars is Earth's neighbor and is also located in the habitable zone, so it has a unique geographical location. However, after field exploration, it was realized that Mars is a waste planet, with no atmosphere, no magnetic field, and no plants, and what is the planet that humans have migrated?
While exploring Mars, people also discovered a truth.
Mars is a microcosm of Earth's future.
If the earth has no magnetic field, can not protect the atmosphere, without the atmosphere, most of the earth's organisms will be radiated to death by the sun, every day there will be meteorites falling, some organisms will be smashed to death. Luckily survived, but because of the unbearable high temperature and cold, the terrible temperature difference made many creatures die, and perhaps luckily survived, but the high temperature will evaporate the liquid water on the earth, and the earth's organisms will die of thirst or starvation.
When all the creatures on Earth disappear, the Earth will slowly become the current Mars. What a terrible thing!
summary
The only way for human beings to save themselves is to develop science and technology, especially aerospace science and technology, and only when there is a qualitative breakthrough, there may be a glimmer of vitality. But these fears may be hundreds of years from now, or even a thousand years from now, but it is not a bad thing to plan ahead.
