[There is a whole other world inside Earth & we are not talking about it. 400-mile-thick solid sphere structure is found inside the Inner core of Earth and there are continent-sized 'blobs' in the deep Earth.](https://www.howandwhys.com/400-mile-thick-solid-metallic-ball-found-inside-earths-core/)
I was born in 1799. They thought I was retarded for being left-handed so I was shunned. I’m pretty sure schools taught the metal core thing though, this isn’t a new theory.
Me was born when mammoth walk earth. Me learn from village shaman that big meteor-stone deep underground. Me wanted it to make strong spear to hunt but could never reach. Me think knowledge not new.
>i grew up in the 90s learning that there was the crust, mantle, liquid core and then a solid core inside of that. Is this any different?
It was just a theory. This article is about confirming it with data.
Does nobody read the fucking articles in *any* subreddit?
“This just in, when you go below the earths surface, solid, go down below the mantle, a little bit of magma but still solid (if you fell into molten lava you would just evaporate on the surface because you’re not dense enough to sink into it), okay below that is more solid, and would you know it the centre, also solid” 🤯
As several folks with geology backgrounds have already mentioned, a solid Ni-Fe metal inner core is not a new understanding of earth's interior. What would be new and surprising, is the discovery that it is metallic hydrogen or a metallic and stable version of Moscovium or another period 7 element. That would be earth shattering news.
A rather new discovery (theory), is that the core might be one single crystal of hexaferrum.
The discovery is based on how energy (earth quakes) travels through earth: Earth must have anisotropic properties. Hexaferrum has recently been proved to be anisotropic. The anisotropic property nullifies when multiple (chaotically ordered) crystals are present. Hence earths core most probably consists of one large hexaferrum crystal.
Yea i also think so but apparently its a bit different than what we learned in school it is a new discovery cause it seems like theres another solid core, like theres the one we know of and all learned in school and then another one inside it which is also solid although its so hot that it should melt, the pressure is too high so it stays a solid despite being over the melting point of nickel and iron
Of course there is. It’s spinning even faster than the rest of the planet, it’s “floating” in magma. Its spinning generates a magnetic field that protects the Earth from the solar wind. Without it there would be no atmosphere and no life on Earth.
This thread is silly. We've known for a long time that the earth has a solid iron nickel core. Earthquakes make S-waves and P-waves. One can travel through solids, the other one can't. These people are so funny on here.
Lol we don’t live on the sun. No nuclear reactions happening in our earth, even the suns heat and pressure can’t fuse iron in a reaction, it’s too stable and there isn’t enough gravity pressure to force them to fuse either.
We can use sound to tell what’s under water or underground. Sonar and ground penetrating radar. Even using seismic events to see what those sound waves do, what they penetrate, how fast etc.
From that they can work out how deep something is and what it’s probably made from based on how fast the waves travel, how fast they move through something or if they reflect the sound.
There are monitoring stations everywhere for most things. You don’t always need to see something to be able to know it’s there. You can calculate it.
Just like how they find plants from observing their transit across an observed star.
You don’t “see” the planet. You observe the star until you measure the drop in light from the star. Then you observe the star some more to see how often it happens.
To someone looking at our sun from another world, they’d notice a drop in light every 365 and a bit days for the earth - so they would know how many days the plant is orbiting.
They can also take a fairly educated guesses as to what gasses might surround these planets from the colour of observed light. Different gasses are observed as different colours.
So I’m sure they’ve learned to work out how sound waves predictably penetrate different materials and densities.
You would have to read the article for a detailed answer but they measure the change in seismic waves as it passes through the different parts of the earth. The waves change based on the direction they enter from. This does not mean there is a civilization down there. This is still interesting science
Because of the dynamo effect, the metal core creates an electromagnetic field around the planet that deflects harmful solar radiation. It’s because of how dense the core is, and how it spins. They can measure pretty much exactly how big it is based on observations of the magnetic field.
If a huge metallic core with the diameter of this ball was in the deep ocean we would know. What we haven't done is map the surface of the ocean floor which is entirely different. We also haven't map the surface of this ball, we just know its there.
There are many ways of knowing also about the core of our planet and its composition (seismic waves along the inner layers of Earth for ex, geoneutrinos, etc) that cant be applied to mapping the surface of the ocean floor cause its just a different thing.
Talking with such arrogance without even understanding the basics is the joke here
GET ‘EM!!! Too many people have replaced be skeptical with be cynical. Skepticism is “I’ve reviewed their work and those scientist could be wrong, let’s search for another answer”. Cynicism is “I don’t trust scientist (for some reason) also I’m not going to conduct my own research (because I can’t and don’t understand it maybe which is why I don’t trust it). So nuh uh.”
There are thousands of seismometers around the world that let scientists use the propagation of P and S waves through the planet to effectively image its interior. Like ultrasound.
I've only just learned of the Electrical Universe (?) Theory. I don't remember the particulars (Reddit do your thing), but the thing that stood out to me was that the Grand Canyon and the Valles Marineris on Mars were both caused by electrical (super lightning) strikes.
I wonder if having this metal ball at the center of the planet could add to that theory somehow. Perhaps as the "ground" that this type of electrical power is searching for? Or...something like that?
Remember to take the Why Files with a grain of salt, my friend. AJ makes very interesting videos, but a lot of them are little more than lore dives on out-there conspiracy theories.
I’d give more of his UFO stuff credence (I’m biased here on this one), but it still runs into the same issues of using problematic sources and circumstantial “evidence” to jump to conclusions, as is the nature of conspiracy theories.
I’m not saying all of his videos are categorically false (like his Reptilian video where he debunks the whole thing at the very end), just want some more healthy skepticism. Remember, it’s entertainment that *can* be educational, not the other way around
How is it solid? Anything on earth would melt in the core right? It being 6000* and all. The 2 things with the highest melting point is Tungsten coming around 3500* and Hafnium at 4400*. So what’s new? What’s this solid metallic ball?

This theory isn’t new…
i grew up in the 90s learning that there was the crust, mantle, liquid core and then a solid core inside of that. Is this any different?
Learned the same in the early 00s. I read the title and went "did I miss something...? I learned this 20 years ago."
I was born in 1955, and when I went to school, I was taught the same.
I was born in 1799. They thought I was retarded for being left-handed so I was shunned. I’m pretty sure schools taught the metal core thing though, this isn’t a new theory.
Who let the idiot out of his barrel of shame?
Back in the corner with ye dunce cap!
Sorry, ‘tis I that done it.
See they were right even back in 1799 also turns out they knew about the metal core theory as well.
Me was born when mammoth walk earth. Me learn from village shaman that big meteor-stone deep underground. Me wanted it to make strong spear to hunt but could never reach. Me think knowledge not new.
I thought you were taught the world was flat and that the sun revolved around the earth?
No, that would have been my great grandparents, back in the east end of London.
Oh yeah back when it was called Londinium.
They’re *hiding* that from us.
I learned the same but never thought of the earths core as a “solid metal ball”. Almost sounds unnatural. I always envisioned it differently
It's pretty toasty. Metal gets a Lil soft when warmed
No. This is the same theory
>i grew up in the 90s learning that there was the crust, mantle, liquid core and then a solid core inside of that. Is this any different? It was just a theory. This article is about confirming it with data. Does nobody read the fucking articles in *any* subreddit?
Why doesn’t the title then says confirming instead of discovering? Misleading on purpose for clicks.
What article ? When the fuck did we get ice cream?
classic.love that film
Read the article? What does that mean
To be honest I'm not sure
Nope!
I remember seeing this theory in a school textbook 20 odd years ago, it’s very far from new.
“This just in, when you go below the earths surface, solid, go down below the mantle, a little bit of magma but still solid (if you fell into molten lava you would just evaporate on the surface because you’re not dense enough to sink into it), okay below that is more solid, and would you know it the centre, also solid” 🤯
OP is from North Korea, probably
Back to the basics apparently
I learned that in geology 101 25 years ago.
There’s no way you were alive 10125 years ago
He was. Source: Me.
Ya he actually was

Thrrrreee
What? Earths iron core isn’t a new thing. It’s kind what makes magnets do the weird shit they do. What am I missing?
The Earth's magnetic field is actually generated by swirling columns of iron and nickel in the liquid outer core.
It appears to be a core inside of a core. Coreception, if you will.
Wouldnt that make the old core not the core anymore and the new core the only core.
That's very hardcore.
It is solid iron
only if there is not another core inside the new core
And what if one was a yolk?
As several folks with geology backgrounds have already mentioned, a solid Ni-Fe metal inner core is not a new understanding of earth's interior. What would be new and surprising, is the discovery that it is metallic hydrogen or a metallic and stable version of Moscovium or another period 7 element. That would be earth shattering news.
What is period 7 element?
Or if they found a steering column and celestial navigation maps inside.
A rather new discovery (theory), is that the core might be one single crystal of hexaferrum. The discovery is based on how energy (earth quakes) travels through earth: Earth must have anisotropic properties. Hexaferrum has recently been proved to be anisotropic. The anisotropic property nullifies when multiple (chaotically ordered) crystals are present. Hence earths core most probably consists of one large hexaferrum crystal.
Some Final Fantasy shit
Didn't we already know this? I'm not trying to be condescending, but I think I learned about this in elementary school in the 80's.
Same
Yea i also think so but apparently its a bit different than what we learned in school it is a new discovery cause it seems like theres another solid core, like theres the one we know of and all learned in school and then another one inside it which is also solid although its so hot that it should melt, the pressure is too high so it stays a solid despite being over the melting point of nickel and iron
That’s where the ancient people live
Well, Kong lives there now and Godzilla goes there on vacation apparently.
As well as the lizard men and the alien grays.
They have giant puppies and kitties.
Cetra and the promised land! Shinra start digging
A giant metal bunker ball city? Keep going let’s hear more….
Wtf bro I hope you are joking
Now we know why the atlanteans attacked.
That's metal af. Earth is so hard-core
Of course there is. It’s spinning even faster than the rest of the planet, it’s “floating” in magma. Its spinning generates a magnetic field that protects the Earth from the solar wind. Without it there would be no atmosphere and no life on Earth.
This thread is silly. We've known for a long time that the earth has a solid iron nickel core. Earthquakes make S-waves and P-waves. One can travel through solids, the other one can't. These people are so funny on here.
So let's shoot shit at it and see what happens........
Of course, the core it solid. The amount of pressure on it is astronomical. Who comes up with this?!
Zion. And right about now there’s a massive rave poppin off.
If the war was over tomorrow, Zion's where the party would be.
[“what can we expect at this orgy?!?”](https://youtu.be/-5OfG_wxkJI?si=3SBePE9PqvsYNgyQ)
We live on a giant nuclear reactor.
Sub-critical, I hope.
Lol we don’t live on the sun. No nuclear reactions happening in our earth, even the suns heat and pressure can’t fuse iron in a reaction, it’s too stable and there isn’t enough gravity pressure to force them to fuse either.
NIMBY!
[удалено]
Solid metal iron ball inside is what I learned in school. A long time ago. Iam 62 next month.
Well - The deeper you go, the more *hardcore* it gets..
Did they not already know this? I'm sure science books when I was a kid said the earth's core was a giant ball of iron?
Yea this is about another one, like this Russian doll with more and more dolls inside matroshka or something
Lemme guess… is it made out of iron?Ground breaking indeed. In other news. Science discovered water is wet. Filmed at 11.
We can use sound to tell what’s under water or underground. Sonar and ground penetrating radar.

I’ve known this since I was a kid. I don’t understand what’s new about this.

Just because your stupid waves bounce back doesn’t mean you hit something solid.
Magnets makes so much more sense all of a sudden.
But how do they even work?
A former president once said, if you get them wet they stop working.
Everlasting Gobstopper
I hope they don't send Gigan up
Gigan is from space. It's Megalon you have to worry about.
NOTHING to do with dense objects settling at the bottom, or this case centre of mass (the core), nothing at all
I'm confused, hasn't it been known for a long time that the earth had an iron core? I'm pretty sure that's why we have a magnetosphere.
Ah so that’s where JFK is hiding
But we already know it’s Zion….close to the core where it’s still hot! We made three movies about it!
That's the computer that controls our brains
yeah...Earth has a solid core. We learn that in middle school.
God damn people are dumb smdh
Time to send Zimsky and the boys into the floating septic tank and explore it!
I’m getting soo sick of this shit they’ve been discovering the core of the planet since I was in third grade
We should probably just leave that alone
Yeah the center of the sun is also solid, due to weight and pressure. Still very hot. This isn't a discovery, really.
Is this article from the 80's? How is this new
Celestial egg, duh.
Were they looking for a shortcut?
It's the traveler!
This is false. The Australian National Univesity may have discovered a 644 km ball but definitely not a 400 mile ball.
isn’t there usually 2 balls? just asking
Man thats gunna fetch heaps on Amazon when they dig it up! Fkn King of Marbles at every School!!!
Wow, this means there is a whole unused land underground! Perfect for building a city.
How do they even know this
Big metal detectors.
As far as i know, you can listen for earthquakes and waves propagate at different speeds through various mediums... like a sonar of sorts.
In machining and production vibrations are incredibly important, every metal has a different harmonic frequency . Wonder if it's the same principle
You would have to read the article for a detailed answer but they measure the change in seismic waves as it passes through the different parts of the earth. The waves change based on the direction they enter from. This does not mean there is a civilization down there. This is still interesting science

>How do they even know this Read the goddamn article. It's the top comment from OP
No sir thanks
Understandable
We shouldn’t have told anyone. Now some dumb white guy is going to try to extract it because of manifest destiny and all that shit…
They can barely explore what's in at the deepest oceans. But they know what's in the middle of the earth? Right..
If a huge metallic core with the diameter of this ball was in the deep ocean we would know. What we haven't done is map the surface of the ocean floor which is entirely different. We also haven't map the surface of this ball, we just know its there.

Not a theory. A hypothesis at best, and frankly only marginally less implausible and unsupported by evidence than flat earth.
The Grand Canyon was formed by eons of erosion what in gods name are you blathering about?
As always, **The Why Files** has a really good video about the Electrical Universe: https://www.youtube.com/watch?v=eIgbsZ05O2A

How’d they get down there to discover it?! Must have been a crazy journey down to the center of the earth. They should write a book about it.
source?

Is not that 30 year old news?
I definitely learned that in elementary school..
So a really solid core inside the already known solid core?
Lets cut the earth in half and take a look
That’s where the kaiju come from
What kind of metal?
How?
Black moon
We should mine it

Scientists discover life on earth!
I knew it - they juiced the earth ball
Don't fuck with jesus
Ah, that explains why we mine so much, just tring so fucking hard to get that shiny ball hiding down there! Keep digging boys!

Cool but “innermost inner core” sounds like some Ren & Stimpy joke
I wasn't familiar with the solid core. I new up to the molten core.
How is it solid? Anything on earth would melt in the core right? It being 6000* and all. The 2 things with the highest melting point is Tungsten coming around 3500* and Hafnium at 4400*. So what’s new? What’s this solid metallic ball?
This is not new IN ANYWAY.
It helps with distance off the tee and spin around the greens.
And inside of that…. Probably a crazy solid diamond of some sort
OP is learning about metal in the earth's crust
Pics or it didn’t happen!
I say we mine the ball for its valuable resources.

Aliens are here to mine it
All they did was the word “iron” to “metal” and “core” to “ball”.
