Jessica Irving, a seismologist from the University of Bristol UK, said researchers like to discover a completely new hidden world. “The more we look at it, the more we realize that the Earth’s core is not a lump of iron,” he told Live Science.
Although scientists have known since the 1950s that the earth is not hollow, the planet’s core remains unexplored. This is because the earth’s heat and pressure are extraordinary and no rover is capable of reaching the earth’s core.

Meanwhile, geophysicists rely on seismic waves generated by earthquakes Earth to reconstruct the picture of the workings of the earth’s core. “It’s like how a CT scan works inside a person’s body,” Irving said.
Meanwhile, a geophysicist from the Hawaii Institute of Geophysics and Planetology, Rhett Butler, said this new study is to answer a number of questions from previous opinions. “When you’re in this scientific field, you have to match the data,” he said.
So Butler and his co-authors reevaluated their basic assumption that the Earth’s inner core is essentially solid. In his research, Butler found evidence that the Earth’s core has several parts of semi-liquid and soft iron near its surface.

This research has the potential to revolutionize researchers’ understanding of magnetic fields Earth . “So we saw a lot of detail in the core that we didn’t see before,” he said.
In NASA research, other planets like Mars have a liquid center but lack an inner core and magnetic field. Because of this, Butler and Irving believe, a deeper understanding of the Earth’s core will help scientists understand the relationship between the planet’s interior and its magnetic activity.
