That's non-controversial, regular knowledge right? That the proto iron age happened all over in 1 or 2 centuries in which meteors dropped iron from the sky. It was in regular history books when i was a kid.
They always brush right over why it was raining iron. Isn't that crazy wth is that about?
Um sauce? I have never heard of it. Also Iron Ore is usually not of meteorite origin.
Yeah this one's puzzling me, for the amount of iron ore in the ground we would have seen much more evidence of large impacts if it came down from the sky.
Earth's core is iron.
lol
I am interested in OPs sauces.
I hope they have a sauce for you.
I don't have one on hand bc it was common knowledge. Everytjing I've ever read about the bronze age says that iron was already widespread from meteors and common for tools in Asia and africa and Europe
Iron is pretty common all around earth's surface(though due to its density most of it went to the mantle and core), but it ain't that easy to melt, that's why humans used copper and bronze tools first, and then the forging technology eventually allowed for the smithing of iron tools and weapons.
This is also one of the reasons there's so much legends in all cultures about magic swords. It's a weapon made from a rock that, for all they knew, the gods threw from the sky, that fact oughta make the blade unique, somehow.
Still, not such a thing as iron seeding, just humans figuring out a way of making better stuff.
It's #26 and only has atomic weight of 55. That means it's at the top of the LIGHTEST elements. Why and how could it go to the core? They say the core is 9,400 F. Iron boils away to a vapor at 5,100. How would that work. Also, iron holds NO magnetism above 450 F or so.
Its at the BOTTOM of the lightest elements. Each element gives off energy when its created in fusion. Up to (and including) iron they give off more energy than they cost to create. This means that in a stellar explosion iron will be the last in the fusion chain. After 26 they get more and more rare because it costs more energy to make it than it gives off and they will only be created from neutron capture. This means more iron will be produced than all elements heavier than it.
No one said there was only iron in the core. It's just by far the most abundant. It's also in all the other layers of the Earth, as are all the other elements. It isn't a nice perfect little layer cake. It was (probably) made with a lot of impacts over a long period of time. Think of it more like a raisin cake with raisins all over, with a bonus raisin center.
Boiling point is a function of temperature and pressure, not just temperature. The higher the pressure, the higher the boiling point. The pressure is very high at the center of the Earth.
It creates a dynamo effect. A dynamo is the creation of a magnetic field from a rotating induced electric field.
I bet wiki. Trust me that I know the standard story. Half-truth and non-science from years ago. Prolly should chk snoops, or a geo-physical journal.
I love how people dismiss wikipedia, as if its automatically false. I use wikipedia when it tells the same story as every place else but in a simpler manner. In this case I only used one wikipedia reference. Did you check past the first one?
I can go through the math of it if that will help you. I can show you physics books that tell the same thing. I can point you to experiments that show the same thing. What evidence would you like?
I can provide any level of detail to support what I just showed you that you want.
You asked questions, I answered them. After I showed you the answer, you did not say what was wrong with the answer, you only attempted to discredit the source, without addressing the argument. That is not an attempt to get to the truth, but an attempt to resolve cognitive dissonance with a result of confirmation bias.
If you have determined that no matter what evidence I show you, I must be wrong, then there is literally no evidence that will change your mind. Do you know what its called when no evidence will change someone's mind? On this board when we are talking about the vaxxed, we call that insanity.
You do know that is the theory derived from seismic research in the 30's. By 1940 it was concluded the inner core was "solid Fe" at 9,400 degrees. A bit convoluted how that determination was made, particularly in light of the fact there is no such thing as "solid Fe" above 2,880 regardless of pressure. It did fit the "dynamo" story however. It made sense to think of like a motor/generator. You move the magnet over the coil or the coil over the magnet. They had no idea the earth was part of a solar elec circuit, or that Maxwell had shone 30 years prior that all elec fields produce equal magnetic fields at 90 degrees. If you haven't made the connection this is why the poles wander, as they are doing now, and occasionally flip, as they are about to do. This would not ever happen in the "magnetic iron core" model even if the "solid iron core" were replaced with something both magnetic and solid at that temp (???) and the "molten outer iron core" (cooler but liquid...hmmm) were spinning and conductivity not dropping. 90 year old science. Modern geo-physical scientists deal with much better equipment and much more complex internal structures,... "LLSVPs" and they admittedly know less today than back in the day
The triple point of iron is estimated to be 3800C. The temperature of the core is estimated to be at 6000C. How do we explain the discrepancy? Possibly different states of crystallization. Just like how carbon can form different states at extreme pressures, so can other elements. But it can also be a liquid yet stable form. It doesn't have to be "solid" to be iron and in a permanent semi-solid (coherent) ball.
Is that the "truth"? I have no idea, but neither do you (unless you've been the the center of the Earth and just aren't telling me). It makes a lot of sense that the core is iron, regardless of how the magnetic field is produced.
When we look out into the universe we see a whole lot of iron. Experiments show us that iron is at the bottom of the fusion pile, which gives a reasonable explanation as to why we observe so much of it. Considering that the Earth is a (mostly) solid rock, it makes sense that its core would be iron. Most other rocky planets are also thought to be mostly iron (core) for exactly the same reasons; i.e. what we observe.
As for the sun connection, sure, there is likely a EM connection with the Sun. That doesn't mean that the core isn't iron, nor does it mean that the Earth isn't a dynamo. Just because there may be other elements than we are aware of doesn't mean we need to throw the baby out with the bathwater.
It is true there is a lot of iron. 10% of total mass of 26 and above is generally accepted. Also true Iron and higher mass numbers are created in stars of predictable mass. This is not true with lower mass elements. In fact 1 thru 25 can be and are produced in various quantities even inside earth. While Fe accounts for 10% of mass of all higher elements, don't lose sight of the fact it is far from the most prevalent. H accounts for 90% of the known universe, 2 thru 118 for the rest. "But it can also be a liquid yet stable form" True but a miss use of terms. "Stable" simplify means "not radioactive" ... it's not in the possess of becoming a different element. Also, the crust, a tiny portion of the earth, is mostly solid rock. The majority of mass is in the mantel and is "plastic state" with many LLVSP's very out of balance protrusions... not at all nice little symmetrical shells of concentric nested balls like the nice picks from grade school. Does it make a difference? Yea, it does. I don't know your age but you may well live to see why.
Electric universe look up See The Pattern yt chnl
6,000 years ago we got a mid-cycle solar eruption of H, O, Li, Fe, as well as N and some Fl. Star water. The H and O combine of their own and emit huge electric discharge and the earth passes through rain and ice and falling mud,... for like 40 days or so.
Basically a micronova event.
(shhhh)
Whoa
The core part is, as far as we know, due to the pressure exherted by the weight of literally the whole world resting above it that keeps it all held together. Can't answer for the magnetism part.
That makes no sense. The core just went from molten to highly compressed gas. On the other hand we have all the actual heavy elements,...2x, 3x, even 4x as heavy all over the surface.
To be honest, I'm also confused as to why they say the core is made of iron and nickel, when lead,gold or uranium are far denser.
The whole planetary evolution is bunk like the BB it's tied to. You aren't supposed to know layers are added at regular intervals. Look at the half-lives of un-stable elements (those with half-lives). Don't exactly jive with a 4 billion year old planet does it.
No it literally dropped around and was worked.
You've never heard of Mecca?
Ah, the place where the extremely murder-happy supposedly abrahamic monotheists worship a black rock by walking in circles around. At least the catholics would've made a neat saint statue or it or cover it in gold and jewels or something.
Looks like we are seeing the next "flat earth" ruse.
This time it is iron from the sky. The education level has gone completely to shit.
This is basic knowledge of human prehistory and the chalcolithic transition into the bronze age that every American school kid learned at least through the 90s
Did they teach you that along with the common core math?
I graduated magna cum laude from a four year university in 1998, and they weren't teaching that shit then. You are just another fucking troll.
I graduated high school before 911. You aren't familiar w mecca? That lil tribe just kept one but that was a regular enough thing that many peoples from all corners had meteor iron tools.
There is a ton of iron that comes from layers far older than a few thousand years. There are iron structures that are many times older than that. I have no idea where you get this "non-controversial knowledge" from. I'd suggest you go do a little more research.
The most recent book i read relevant to the time period was "4000 years ago" by something Bibby. Definitely it made mention of it whicj made me recall regularly reading that and raised the question.
4, 6000 whatever lol the chalcolithic
Mmkay. I personally have never heard anything like what you are talking about. Other than your post, I STILL have never heard anything like what you are talking about. I'm not going to say you're wrong, though I have seen no actual evidence to support such a claim, but I will say that it is far, far, far, far, far, far from "non-controversial knowledge."

Ah. I misunderstood what you were talking about. Yes, its possible our first iron was from asteroids because it didn't need to be smelted to be used. In asteroids, especially after surviving the burn off from entry into the atmosphere, it is already in a relatively pure form.
I don't know if it's true that we only used it in that form prior to relatively recently. I've been seeing a lot of stuff lately about us having knowledge of smelting iron going far back, but it looks like it was lost knowledge. During the time period in question (3-10k years ago), it is entirely possible that it was gotten from asteroids until we "relearned" how to smelt iron a couple thousand years ago.
Well 1 tension in your timeline is thinking "man" had this technology andmaybe not "some men" who probably made up stories about it and only taught sycophants and hucksters the racket and the cover story
The iron age came because man figured out how to smelt iron from iron ore, which is all over and in deep layers throughout the earth...
There was no "raining chunks of iron".
False it began w surface iron that literally fell from the sky. This was seriously regular ass narrative until evidently nowadays?
Not false, there is zero evidence of this anywhere.
My well water rusts if it's not treated because of all the iron in the rocks here. Those rocks are a lot older than 6,000 years
There is iron all in the soil and rocks here. In fact there are old iron mines all around. The water from the well has particles of iron in it. Before I put in an expensive water system, a glass of water would turn brown from the iron particles.
I suggest watching The Thunderbolts Project on youtube for a new take on our Planets history. It suggest major events like The Grand Canyon were created in hours not millions of years from huge Lightening strikes, caused by massive objects and micro novas that lead to planetary size lightening, if you look at the Grand Canyon from Google earth, it looks like a lightening strike. They bring receipts too.
Krypton?
I used to like him until Chris White did a documentary on him... Seems to make stuff up as he goes along.
Great reply, ty!
