A study published Tuesday suggests that Earth has an additional inner core that may tell the tale of a “significant global event from the past.”
The highly specialized study published in Nature found that there is a giant metal ball sitting within the Earth’s inner core, known as the innermost inner core (IMIC). The ball is roughly 800 miles, and has been part of geological theory for quite some time, but the results from the study almost conclusively prove its existence (since we can’t get down there and check with our own eyes).
The study was conducted by a team from The Australian National University, which used data from seismic observations to determine that previous theories on the existence of the IMIC were correct.
“Earth’s inner core (IC), which accounts for less than 1% of the Earth’s volume, is a time capsule of our planet’s history,” authors Thanh-Son Phạm and Hrvoje Tkalčić said in the published study. “As the IC grows, the latent heat and light elements released by the solidification process drive the convection of the liquid outer core, which, in turn, maintains the geodynamo,” referring to the mechanism that generates Earth’s magnetic field.
The discovery is helping to explain how our planet developed to sustain life, and offers new insights into how researchers can identify other planets that may host aliens, Vice argued. It’s one of a slew of new studies that seek to determine more about our geological history, and how our planet and moon were formed within our cosmos and led to our creation as a species from a scientific perspective.
Rotten to the corpse Ping!..............
“offers new insights into how researchers can identify other planets that may host aliens”
Here’s a good general rule of thumb:
Ask yourself, does the planet in question exist in your imagination, or in a novel, television show, video game or movie?
If yes, then it may host aliens.
If it’s in the real world, probably not.
Ask yourself:
Would Sigourney Weaver go there?...................
Of course it does. That's where the dinosaurs live.
I think they should drill a hole and send Jerry Rivers down to make sure
And the VIEW CREW......................
Whenever I need credible research on the inner core, forget Earth and Planetary Letters, Tectonics, or Journal of Geophysical Research.
I just go to "Vice". [/S]
My guess is the molten metal core is full of iron, uranium, lead, gold, copper, silver and all the other heavy metals in one huge mass like the layers of an onion.
They all sank into the center when the Earth was being formed, and every now and then some of them leak out from volcanoes.................
The core of Earth is likely very rich in heavy precious metals like good and platinum - all unreachable.
That was the stupidest movie ever made...................
Some geologists in the UK want to drill thru the mantle.
What could possibly go wrong with that?.....................
800 miles of what? Circumference? Diameter? Radius?
The more we learn, the more we realize we don’t know.
Diameter probably.................
Even this is just a SWAG...................(Scientific Wild Ass Guess)..............
bfl
“The ball is roughly 800 miles”
Under the surface?
In diameter?
Blah, blah, blah. They know about as much about the earths core as they actually know about gravity.
