Hollow Earth Discovered with difference in Core of the Earth. Scientists discover a “new hidden world” in the center of the Earth. They discover that the center of the earth is not as it was believed | Chronicle. For more than half a century The scientific community thought that the inner core of the Earth was a solid ball of compressed iron alloy surrounded by a liquid outer core. But new research, published in the journal Physics of the Earth and Planetary Interiors, suggests that the firmness of the planetary ball varies from hard metal to semi-soft to liquid.

“The more we look at it, the more we realize that it is not a boring drop of iron,” said Jessica Irving, a seismologist at the University of Bristol in England, who was not involved in the study. “We are finding a completely new hidden world”.
In a way, the inner core of our planet It remains as mysterious as it was when Jules Verne published his fantastic “Journey to the Center of the Earth” in 1864. Although scientists have known since the 1950s that our planet is not hollow, as Verne predicted, the interior of the planet is still unexplored; the immense heat and pressure are simply too great for any human or human-made probe to travel there.
“Unless something terrible happens to our planet, we will never have a direct observation of the Earth’s core.”, said Irving. Instead, geophysicists rely on seismic waves generated by earthquakes. By measuring these massive vibrations, scientists can reconstruct an image of the inner workings of the planet in a way that is “similar to a CT scan of a person,” he continued.
These waves come in two main types: straight-line compression waves and wavy shear waves. Each wave can speed up, slow down, or bounce off different media as it travels across the ground. For Rhett Butler, a geophysicist at the Hawaii Institute of Geophysics and Planetology, the new study began as a matter of mismatched numbers.
Butler was observing how seismic waves created by large earthquakes in five different locations travel through the Earth’s core to the exact opposite side of the globe. But something was wrong: Earthquake shear waves, which should have passed through a solid ball of metal, were instead being deflected in certain areas.
The numbers surprised Butler. He knew the mathematics of seismic waves was correct, which could only mean one thing: the scientists had the wrong structure. “When you are in this business, you have to match the data”, said.
So, Butler and his co-author reevaluated their basic assumption that the Earth’s inner core was solid in its entirety. They found that the waves they observed worked if, instead of being a solid ball, the nucleus had pockets of liquid and “soft”, semi-solid iron near its surface.
So what do you think? Can this new discovery mean something for humans? or is it like a Journey to the centre of the Earth?
