In the universe, the energy is very powerful, and the high-energy rays and electrons flying in the sky will definitely swallow up life on the earth without the protection of the earth's magnetic field.
The wind of the sun will also play a great role in the life of the earth, these high-energy rays in space form deadly radiation, but under the shield of the earth's magnetic field, they will not cause harm to life on the earth.
However, the Earth's protective umbrella is not perfect, the Earth's magnetic field is not static, and the Earth's magnetic poles will move in the process of the Earth's development.
The flipping of the geomagnetic pole means that the geomagnetic overturn, once this flip occurs, it will have a great impact on life on the earth, and this impact will even lead to a real "doomsday".
So what does this flip mean, how will it affect life on Earth, and so on.
1. Umbrella.
The Earth's magnetic field is like a protective umbrella, which can block the harm of high-energy rays from other galaxies and solar wind, and can protect life on Earth.
Scientists have always had different views on the origin of the earth's magnetic field, but they believe that the earth's magnetic field is generated by the flow of partially liquid iron-nickel in the earth's core.
Experiments on Earth have also confirmed this, and only the iron and nickel in the earth's core are flowing to produce a magnetic field.
The distribution of geomagnetism on the earth also has a certain law, the outer core of the earth is the flowing liquid iron-nickel, and the geomagnetism is produced by the flowing iron-nickel in the outer core.
This means that the position of the geomagnetic field is not fixed and is not polarized.
Just like the north and south poles of a magnet, the magnetic force is omnidirectional in either direction.
The geomagnetic field is also in the flow of the earth's convection system, and the position of the geomagnetic field will change slowly, but this change is quite regular, and this change is very slow.
There are already many scientific research stations on the earth, and these research stations are built in various regions of the earth, and these scientific research stations have measured geomagnetism, and these data are from the observers of these scientific research stations.
But recent data show that the movement of the geomagnetic poles is accelerating, although the position of the geomagnetic field will change constantly, but the speed of change is very slow, but in the past two hundred years, the geomagnetic field has moved faster and faster from west to east, faster than any previous period.
And for the past 3,000 years, the geomagnetic field has moved at a rate of only 15 kilometers per year, but since 1900 this speed has been increasing.
In 2001, scientists carried out the latest measurement of geomagnetism, according to the data of this measurement, the speed of geomagnetic movement has reached 40 kilometers, and this is still 18 years ago, it can be seen that the speed of geomagnetic movement is constantly accelerating.
In 2018, according to NASA, the geomagnetic field was declining ten times faster than previously predicted, and the strength of the geomagnetic field was rapidly weakening.
In 1859, there was a very severe solar storm that caused the Northern Pole to see the auroras, and at the time, people in some areas thought it was the end of the earth.
So how did this solar storm event become so powerful that the auroras could be seen in the surrounding areas of the North and South Poles, while also having an impact on the power grid and appliances?
This is because, in the year 1859, it happened to be the peak of the solar activity cycle, and in that year, dozens of solar flares erupted on the sun, and there were several large solar flares, and there was also a large-scale solar storm, which entered the Earth's atmosphere at about four o'clock in the morning, and the level and energy of this storm were also extremely amazing.
If this storm occurs now, it means that the global power grid and equipment will be paralyzed, the transportation and communication between various countries will be interrupted, and human life may return to hundreds of years ago, and the electromagnetic pulse storm will also make all the aircraft and stall equipment fail, human communication will be paralyzed, and communication between countries will also be interrupted.
Once the earth's magnetic field is reversed, it will cause great changes in the climate, and naturally it will also cause great changes in various organisms around the world.
Second, the hazards of magnetic flipping.
In the process of turning the geomagnetism, the survival of the earth's organisms will face a great test, all kinds of organisms on the earth are adapted to the existence of the geomagnetism, if the geomagnetism changes suddenly, then the organisms on the earth will be irradiated, which will eventually lead to the inability of the species on the earth to survive, and eventually will be extinct.
Fortunately, the earth's geomagnetic field does not suddenly flip, but after thousands or even tens of thousands of years of precipitation, the phenomenon of flipping will eventually occur.
About 70 million years ago, the geomagnetic reversal was relatively frequent, at most several times in a year, and even dozens of times in a year, but after that, the polarity of the geomagnetic field became longer and longer, becoming a flip every hundreds of thousands of years.
And the geomagnetic flip has also happened many times, a total of 171 flips, and every 450,000 years or so, and 770,000 years ago, the last polarity flip also happened, that is, 770,000 years have passed since the last flip.
At this time, it is not far from the next geomagnetic flip, because the movement and change of the geomagnetic field are regular, and the speed of the geomagnetic movement is also accelerating, and it can be assumed that the geomagnetic flip may happen again soon.
And in the geomagnetic flip, human technology and science are unable to stop, can only adapt to the changes brought about by this geomagnetic flip, but the geomagnetic flip will have a great impact on human civilization, and some electronic devices of human beings cannot survive.
However, human beings will still find a way to survive in a bad environment, and human beings may also establish a new social model, but the earth that has undergone this reversal will be a new earth, because the environment on the earth will also become different.
epilogue
Not only that, scientists are also hoping to find a law that can predict the time of geomagnetic overturning in the study of geomagnetism.
At the same time, changes in geomagnetism may be part of the natural evolution of the earth, and human beings should better understand and respect the laws of nature and not forcibly interfere with them.
