Scientists have found that the earth’s magnetic field is weakening. Where should we go in the future?

The earth is the only planet with wisdom and civilization in the solar system. The reason why the earth has life, rich ecosystem and the existence of human civilization is related to the earth itself and the position of the solar system.

The earth is in the habitable zone of the solar system. The sun gives the earth warm sunshine and temperature. There are countless wandering planets and meteorites in the universe. Why hasn’t the sun been hit by these meteorites? The reason is that there are several major planets in front of the earth. Jupiter, the largest planet in the solar system, is in front of the earth. If a meteorite collides with the earth, it will be intercepted by Jupiter when passing by it. The moon, a natural satellite outside the earth, has also blocked the impact of some meteorites on the earth. It can be seen that the earth has received so much care to live in the solar system healthily and happily.

In addition to planet protection in outer space, the earth itself has strong protection. We know that there is a lot of radiation in the universe, especially the solar wind invading the earth all the time. The first line of defense of the earth is the thick atmosphere, which can not only make meteorites fall into the earth burn, but also disappear when they fall to the ground, so that the earth will not be hit by meteorites. On the other hand, it can effectively block the invasion of solar wind and other cosmic rays.

Another defense line of the earth is the earth’s own strong magnetic field, which is more important than the atmosphere. The reason why the earth has such a strong magnetic field is that scientists believe that there is a huge iron block in the center of the earth. The greatest function of the earth’s magnetic field is to block the solar wind and other cosmic rays. When the solar wind and other cosmic rays rush towards the earth, they will be blocked by the earth’s magnetic field thousands of kilometers away from the earth, deflecting these charged particle flows, thus greatly reducing the flow of charged particles to the earth. Sometimes the aurora we see in the north and south poles is the result of the battle between the earth’s magnetic field and the solar storm.

The earth’s magnetic field is so important that we should protect it. However, scientists have found that the earth’s magnetic field is weakening. What’s the matter? If the earth’s magnetic field disappears in the future, where will mankind go?

In fact, the weakening of the earth’s magnetic field is related to the constant impact of the solar wind and other charged particle streams on the magnetic field. We know that the solar wind charged particle streams are very powerful. For countless years, they have been attacking the earth’s magnetic field. It’s normal that the earth’s magnetic field is weakening. But at present, we have nothing to do with it.

Another reason may be related to the continuous destruction of the earth’s environment by human beings. In the past century, despite the rise of the industrial revolution and the rapid development of human science and technology, the environment is constantly being destroyed. In the future, the resources on the earth’s surface will be less and less. Human beings are likely to dig deep into the earth to exploit resources. Once the iron ore deep in the earth is mined in large quantities, it may speed up the development of the earth The weakening of the magnetic field.

Once the earth’s magnetic field weakens by more than 50%, the first impact is the atmosphere. The atmosphere may become thinner, solar wind and other cosmic rays are more likely to invade the earth’s surface, and water resources will evaporate. The most important strong cosmic rays will greatly increase the probability of human disease, and the earth’s ecosystem will also undergo dramatic changes. Some scientists even say that once the earth’s magnetic field weakens by more than 50%, the earth’s magnetic field may reverse from south to north, which is a great disaster for the earth, and mankind will also face the doomsday crisis.

If the earth’s magnetic field really weakens a lot that day, human beings may face the possibility of emigrating to other planets. The premise is that we have to find a planet suitable for human survival, and not too far away from the earth.

However, the weakening of the earth’s magnetic field is a slow process. With the rapid progress of human space science and technology, it is not difficult for future human spaceships to go out of the solar system and look for earth like planets outside the solar system. Or at that time, human beings have entered the interstellar civilization, and spaceships have the ability of interstellar navigation, in case the earth really can’t survive Now, we can use spaceships to migrate to exoplanets to live.

Of course, another way is to artificially increase the intensity of the earth’s magnetic field through scientific and technological means. If the main reason for the earth’s magnetic field is that there is a big iron ball deep in the earth’s core, in the future, human science and technology will have the ability to enter the deep of the earth’s core. We can get a huge iron core from other iron stars on the other planets and move it to the earth’s core, so that the earth’s magnetic field will gradually become stronger The earth’s magnetic field’s powerful protection ability has come back to life, so that human beings do not need to immigrate.

No matter which method, science and technology is the first. As long as we have strong scientific and technological strength, it’s very easy for science and technology to change the world and change the destiny. What do you think, little friends?
