The internal nucleus of the Earth may have been formed in the past twenty years, according to a group of scientists.
It is usually believed that the inner core is formed like the ball, but its edges may actually distort by 100 meters or more in places, according to Professor John Vidal who led the research.
The essence of the Earth is the beating heart of our planet because it produces a magnetic field that protects life from combustion in the sun radiation.
The inner core rotates independently of the liquid external nucleus and the rest of the planet. Without this proposal, the Earth dies and becomes like a arid Mars that lost its magnetic field for billions of years.
The change in the shape can occur as the edge of the internal nucleus touch the very liquid liquid external pulp.
The research was published in the scientific journal Nature Geoscience. Scientists were originally trying to know why the inner nucleus slowed down to a slower pace than the Earth’s rotation before speed again in 2010.
Understanding how the basic earth works is necessary to understand the magnetic field that protects the planet, and whether that may weaken or stop.
Inside our planet is a very mysterious place. The nucleus is about 4000 miles from the surface of the earth, and despite the best efforts, scientists have not yet been able to reach it.
Therefore, in an attempt to cancel their secrets, some researchers measure the shock waves caused by earthquakes while they are through the planet.
The way the waves reveal the type of materials you move, including in the inner core, and helps to draw a picture of what lies under our feet.
The new analysis was considered in the seismic wave styles of earthquakes that were repeated in the same location between 1991 and 2023. This helped show how the inner nucleus changed over time.
Professor Vidal, the world of Earth at the University of South California, has found more evidence to support the theory that during those years the inner core slowed around 2010.
But his team also found evidence of changing the inner light.
It appears to occur on the boundaries of the inner and external nucleus, where the inner core is close to the melting point. The liquid flow in the outer nucleus as well as clouds from the non -equivalent gravitational field may cause deformation.
The paper provides “an interesting concept that must be explored,” said Professor Hrvoje Tkalcic of the Australian National University, which did not participate in the study.
He said that scientists can “provide more enlightening estimates of some important material properties, such as the wife of the inner nucleus, which is one of the least known quantities in modern science.”
Over time, liquid external nucleus freezes in the solid interior nucleus, but it will be billions of years before it becomes completely solid.
This certainly means that the end of life on Earth, but by that time it is likely that the planet has swallowed by the sun.
Professor Vidal’s work is part of the investigations conducted by experts all over the world who are exploring and arguing about what is happening in its essence.
Professor Vidal says: “In science, we generally try to look at things to understand them,” says Professor Vidal.
“Most likely, this discovery does not affect our daily life, but we really want to understand what is happening in the middle of the earth.”
The changes can be related to the changes in the Earth’s magnetic field.
He said: “The magnetic field has had tremors at different times in the past few decades, and we would like to know whether this is related to what we see in the basic internal limits.”
Professor Vidal urged to be careful not to increase the results in ideas that the nucleus will stop alternating any time soon.
He also added that there are still a lot of uncertainty.
“We are not 100 % sure that we are correctly explaining these changes,” saying that the limits of scientific knowledge are always changing, and like many researchers, if not all of them, was wrong in the past.
