Scientists are shedding new light on Earth's elusive fifth layer.
Two Seismologists from the Australian National University found that the Earth has an 'innermost inner core' that may have formed following a 'significant global event' from the past.
Scientists studied many earthquakes and monitored 'seismic waves reverberating through the entire planet.'
'We analysed digital records of ground motion, known as seismograms, from large earthquakes in the last decade.
'Our study becomes possible thanks to the unprecedented expansion of the global seismic networks, particularly the dense networks in the contiguous U.S., the Alaskan peninsula and over the European Alps,' lead author Pham explained.
Both the outer shell of the inner core and this newly discovered innermost sphere have high enough temperatures to melt iron-nickel alloys. However, the immense pressure at the Earth's centre keeps these materials in a solid state.
'Clearly, the innermost inner core has something different from the outer layer,'
Despite being made of the same materials, the different properties of the innermost and inner core determine how fast seismic waves travel through it, a phenomenon called 'anisotropy.'
'We think that the way the atoms are [packed] in these two regions are slightly different.
'The latent heat released from solidifying the Earth’s inner core drives the convection in the liquid outer core, generating Earth’s geomagnetic field.
Life on Earth is protected from harmful cosmic rays and would not be possible without such a magnetic field.'
The metallic ball appears to have been the result of a huge geological event such as a tectonic shift hundreds of millions of years ago.
It now measures roughly the 'size of Pluto and a bit smaller than the moon,

Anyone can make up theories about whats at the center of the planet because everyone knows nobody will ever be able to confirm or disprove any theories about whats at the center of the planet. Its not science, its just stupid wild guesses.
Real scientific theories must be disprovable otherwise they are not science.

I never understood these "general seething" threads. Like what's the point?

Logically, any Acosmist should also include "the inside of the Earth" in the category of non-existent Cosmic Phenomena.

Give example

Quite easy to test and disprove models on the basis of seismology data. There clearly is a core, and the propagation of waves constrains it's properties.

Why not?

your definition of clearly sucks ass bro
what if the core is hollow? didn't think about that now did ya?

Earthquake oscillations would take a longer to propagate.

And what magic power is keeping from all the matter above it from collapsing into the empty chamber due to the pressure? didn't think about that now did ya?

Why can't we drill there and get free energy from the core?

its called dark energy and it explains the expansion of the universe.

Can we just stop this and agree we were wrong about "outer core vs inner core"? Give it an actual name.
