Scientists Discover “Hidden World” In Earth's Core

Scientists discover hidden worlds in the earth's core (Mashable)

JAKARTA – Recently, scientists have discovered a new world hidden in the earth's core. The findings were obtained by researchers when studying the ripples of earthquake waves that move through the Earth.

Citing Sputnik News, the new study, published in the journal Physics of the Earth and Planetary Interiors on September 20, has changed the consensus surrounding the long-held belief that Earth's inner core is a ball of solid iron surrounded by a very hot, liquid outer core.

"The more we look at it, the more we realize that it's not a boring lump of iron," Jessica Irving, a seismologist from the University of Bristol in England, who was not involved in the study, told Live Science. “We discovered a whole new hidden world.”

The study analyzed how the shifting waves created by earthquakes travel through the globe to the Earth's core, which neither humans nor machines can pass through.

The distribution of seismic waves from earthquakes operated as a kind of "sonar" helps researchers such as Rhett Butler, of the University of Hawaii and his colleague Seiji Tsuboib who works at the Japan Center for Earth Information Science and Technology. They "see" the depths of the planet in detail.

Butler told Science Daily that the research is of more than academic interest and sheds light on "Earth's composition, thermal history, and evolution."

Even so, scientists have not described in detail the "hidden world" in the earth's core.
