The theory that states five percent of the earth's core is formed from sulfur, oxygen, and silicon gums will be indisputable.
Dream - In the world of science, almost all scientists agree the earth is composed of 85 percent iron and 10 percent nickel, and the remaining five percent is a combination of sulfur, oxygen and silicon.
At least, this theory is believed to be the strongest theory that explains the earth's core. But the above theory will soon be in doubt.
This is because there are findings by geophysicists Tohoku University Japan, Eiji Ohtani with his team call it silicon is an element that occupies 5 percent of all the elements forming the earth.
In the experiment, Ohtani combines elements of iron and nickel mixed with silicon in very high temperatures and pressures, resembling heat at the earth's core. As a result, the data of mixed materials observed using X-rays is identical to the Earth's core data in the form of seismic waves.
"Our latest experiments show that the remaining five percent of the Earth's core is composed mostly of silicon," Ohtani told AFP.
Ohtani believes the findings he discovered can help uncover the mystery of whether the Earth's surface is rich in oxygen in the early days of formation. This is because oxygen is a mystery element in the earth's core.
However, Ohtani still opens the possibility of other findings that strengthen the results of his research. He reminded his findings still need further research and confirmed further.
A group of scientists believe if the earth's core contains silicon, it means the planet is relatively rich in oxygen during its formation. They believe that oxygen exists when the earth is formed and is not trapped in the earth's core.
While Ohtani doubts the existence of oxygen at the core of the earth. He based this on the fact that the difficulties of silicon co-exist with oxygen in the same place.
Earth is believed to be composed of three main layers. The three layers are the solid outer layer, where the ecosystem lives, the mantle consisting of hot magma and other semipadat materials, as well as the earth's core.
While the core of the earth itself is divided into two layers. The outer layer is iron and liquid nickel, while the inside is a solid ball of heat composed of iron.
Ohtani presented his findings at the American Geophysical Union's scientific forum in San Francisco last December. He is preparing to file research papers for a scientific journal.
