The earth’s magnetic field is an indispensable protective layer for life on earth, but in recent years European scientists have monitored its strength to weaken, which makes people worry, will the earth go the same way as Mars in the future?
For example, the power system is paralyzed; for example, radio communication is interrupted; for example, the navigation of ships or air planes at sea fails; even artificial satellites are scrapped and so on.
Because of the existence of the earth’s magnetic field, it intercepts most of the high-energy particles brought by the solar wind and brings them to the polar regions of the earth, effectively reducing the magnitude of the disaster, and at the same time forming a beautiful spectacle aurora at the two levels.
What is the warning of the decline in the strength of the global magnetic field?
In 2020, European media reported that after decades of monitoring and research, researchers found that the strength of the Earth’s global magnetic field has dropped by about 9%. The study also found that the magnetic field strength decreased most significantly in the regions of South America and Africa in the southern hemisphere.
In fact, it is not the first time that this phenomenon has been discovered by humans. A little earlier, an artificial satellite named “Astez” had monitored that in the sky above the Earth’s Arctic Ocean and the South Pacific, the Earth’s magnetic field was almost weak enough to have a “hole” in the magnetic field.
So, what warning does the phenomenon of the Earth’s magnetic field drop have for mankind?
Scientists have found that this decline in magnetic field strength is likely to be a precursor to the reversal of the Earth’s north and south magnetic poles.
The age of the earth is nearly 4.6 billion years. Scientists have found through research that the magnetic pole of the earth has indeed undergone magnetic pole reversal in history, and this phenomenon of magnetic pole reversal has been repeated hundreds of times. Scientists predict that a magnetic pole reversal is likely to occur this century, 780,000 years after the last.
Scientists also said that the earth has not completely lost its magnetic field in the magnetic field reversal in the past. Even if the magnetic field is reversed, the weaker magnetic field can still provide protection for the earth to a certain extent. But scientists speculate that the continued weakening of the magnetic field brings many different experiences to life.
In fact, the compass may be temporarily useless on that day, because even in the area with the highest magnetic field strength, the magnetic field strength is so weak that it does not work for the compass.
Due to the overall weakening of the earth’s magnetic field, the wonderful auroral phenomenon will also occur in the lower latitudes of the earth, and the sky near the earth’s equator will become brighter.
In addition, weak magnetic fields will weaken the ozone layer, which will increase the risk of human exposure to ultraviolet light, which will greatly increase the probability of human skin cancer.
Is Earth going the way of Mars?
The Earth’s magnetic field is the spatially distributed magnetic field around the Earth. But why the earth produces a magnetic field has always been a subject of continuous research, and many hypotheses have been put forward.
Such as rotating body effect theory, magnetic field line kink theory, Hall effect theory, electromagnetic induction theory, generator theory and so on.
After years of observation and testing, the “generating body theory” is a relatively more recognized theory. In simple terms, the theory believes that the conductive liquid inside the earth generates a steady electric current when it flows, and this electric current generates the earth’s magnetic field.
According to this theory, if one day the flow of conductive liquid slows down or even comes to a standstill, then the Earth’s magnetic field will also weaken or even disappear forever. If we continue to sort out this way of thinking, will the earth really take the old path of Mars in the future?
Just imagine, if the conductive liquid in the earth’s core gradually slows down for some unexplained reason, and this slowing down trend is unidirectional and irreversible.
Then, the strength of the earth’s magnetic field will gradually weaken with the trend. When this slowing trend continues, the earth’s magnetic field will disappear when the earth and the inner conductive liquid will stop in a certain day in the future.
Earth’s magnetic field changes
If the Earth’s magnetic field disappeared, the Earth would be exposed to the solar wind and cosmic rays without any protection, which would bring devastating catastrophe to the Earth.
First of all, the solar storm directly interferes with the aircraft in space and causes anomalies; the solar wind will directly act on our atmosphere and blow it away, so that all life on earth will receive direct damage from cosmic radiation;
Cosmic radiation will directly paralyze human power, communication, and navigation systems, and the world will fall into chaos; as the atmosphere disintegrates, it will cause the entire earth’s atmospheric system to be disordered, such as flash floods in some places, extreme droughts in some places, and then frequent geological disasters; The disaster is gradually transmitted, and the creatures on the earth appear extinct.
Birds in the air will be affected first, followed by terrestrial creatures. With the loss of atmospheric circulation and the evaporation of seawater, marine life will not be spared.
If this is the case, then the earth will indeed become a dead planet like Mars in the future.
Epilogue
Do you feel a chill down your spine when you see this moment? Take a sip of water to cool off, these disturbing possibilities are just speculation. Moreover, these speculations are also future prediction models based on human knowledge of the current world’s very limited detection and acquisition.
As more information is explored, the fallacy of speculation may be discovered, and at that time, it may be found that today’s worries are completely overwhelmed.
Plus, there’s a lot of good news to look forward to. In recent years, when humans were exploring Mars, they accidentally discovered evidence of the existence of water on the surface. Humans are also actively studying that Mars can be built into a habitable immigrant planet in the future. Start preparing for immigration.
