Find out the last ingredient that makes up the Earth core

After years of searching, scientists finally found the mysterious factor in the structure of the Earth's core.

For a long time, scientists have always wished to find out what exactly is the mysterious element at Earth's core?

And the Japanese research team recently found the answer. Specifically, the research team at Tohoku University stated that the metal core in the center of the Earth consists of iron and a large amount of nickel and that mysterious factor is silicon.

Silicon is a major factor that accounts for about 5% of Earth's inner core.

Lead researcher Eiji Ohtani from Tohoku University told BBC News: "We believe that silicon is a key factor accounting for about 5% of the Earth's inner core and this weight may be silicon mixed into the alloy. iron-nickel ".

Previous studies have revealed to us the key components of each Earth's crust, including the inner core. Specifically, Earth core layer has 85% iron and 10% nickel.

That means that the remaining 5% is left open to anyone who can come up with a convincing hypothesis. And now, we have found that mysterious substance.

To draw this conclusion, Eiji Ohtani and his team conducted experiments to monitor the process of reconstructing pressure and temperature conditions in the core of the Earth. The experiment was performed at about 5,400 degrees Celsius (9,800 degrees Fahrenheit) - equivalent to the Sun's surface and 3.6 million times the Earth's surface pressure.

By adding silicon to an iron and nickel-containing core simulation, experts discovered they could make materials similar to those predicted with previous seismic surveys.

The core layer in Earth has a diameter of 2440km.

However, experts also said that they should continue testing because some other factors such as oxygen have not been completely excluded.

It is known that the core layer in Earth has a diameter of 2,440km - the size close to Pluto. The interactions of this substance with the chaotic outer core can create a magnetic field that protects life.

So if we can better understand this mysterious substance and learn more about it, they will really be useful and create momentum for us to answer long-term mysteries.
