A “new world” has just been discovered in the Earth’s core

This is a discovery that opens up a whole new perspective. A discovery that has revolutionized our understanding of the heart of our planet: Earth’s inner core is not a solid sphere of iron alloy, as scientists have long thought. This core is actually relatively soft, like dough, new research shows, published Sept. 20 in magazines Terrestrial physics and planetary interiorsSt.

In their study, the geophysicists analyze the seismic waves generated during earthquakes to create a kind of globe and depth scanner. Problem: By observing the behavior of underground vibrations in contact with various underground components, the scientists realized that something was wrong. The data collected is inconsistent with the generally accepted assumption that the Earth’s inner core is solid from end to end. “We have found a new hidden world.”, explained to Live Science’s Jessica Irvingseismologists and members of the research team.

This whole new world actually consisted of various consistencies of iron, from very hard to semi-soft metal, even molten in places. On its surface, its core even had pockets of pale iron, Space.com said.

This discovery is not only fundamental to our understanding of how the Earth works: it also allows us to better understand the relationship between a planet’s core and its magnetic activity in general. Because while on Earth the magnetic field is generated by the movement of liquid iron in our planet’s outer core, the inner core of interest here is still important. It will be very useful to change this field, the scientific media added.

Gradually, scientists managed to unlock the secrets of this fiery heart, too hot to explore. In June 2021 for example, they found that the earth’s inner core grew irregularly and anomalously under Indonesia. A strange and inexplicable phenomenon, which shows the extent of the mystery that still hides the center of our planet.
