Scientists Discovered the Earth has Two Inner Cores by Using Ultra-Sound like Equipment Similar to What Doctors Use

Man has traveled billions of miles into deep space exploring areas as far as Pluto, landing on a comet and observing the mysteries of black holes. However what is beneath our feet is largely undiscovered.

Well, it’s always there and anytime somebody has some new ideas how to bore through tons of earth without expending a lot of time and energy, they are always welcome to do it and dig right in. The research we are about to discuss may just have the solution to what we have been discussing right this very moment.

Now with a new system of using seismic waves, the “deepest mystery” wouldn’t be that deep and mysterious anymore. What researchers have discovered so far is something all earthlings wouldn’t have expected. That’s always the case about new discoveries.

What is it? The Earth’s core has an inner core of its own. It’s a condition that may help us in discovering more about our planet.

“Even though the inner core is small – smaller than the moon – it has some really interesting features,” said Xiaodong Song, professor of geology at University of Illinois.

“It may tell us about how our planet formed, its history, and other dynamic processes of the Earth. It shapes our understanding of what is going on deep inside the Earth,” Song added.

Utilizing seismic waves coming from earthquakes, researchers did a scan underneath the planet’s surface same way doctors use an ultrasound device to see what’s inside their patient’s body.

The technology gathers information not from the initial wave of an earthquake but from its residual reverberations.

The inner core once believed to be a solid ball of iron, is a more complex structure after all.

What the team discovered is a separate inner core half of the size of the entire inner core.

“The fact that we have two regions that are distinctly different may tell us something about how the inner core has been evolving,” Song said.

The study appeared in the journal Nature Geoscience.
