Did you know that gold is extraterrestrial? Instead of arising from our planet’s rocky crust, it was actually cooked up in space and is present on Earth because of cataclysmic stellar explosions called supernovae. CERN Scientist David Lunney outlines the incredible journey of gold from space to Earth.
Lesson by David Lunney, animation by Andrew Foerster.
Everybody knows that gold comes from the end of a rainbow.

Lars Aarton lmao
I just knew somebody had already beat me to this quote
But why tho
TED-Ed: We can manufacture gold!
also TED-Ed: We actually cannot, but hypothetically yes!
😝
Well yes, but actually no
with electron stripping it will happen.
Think atuotomic gold
In other words: yes we can. But no. But still yes
Him: Gold is about 20x denser than water
Me: Laughs while watching duck tales on tv
I know its a cartoon, but to be fair, coins more often than not dont equal gold.
“Although gold is very dense, about 20 times denser than a duck”
-Kurzgesagt - In a nutshell
The ancient Aztecs called gold "the sweat of the sun". Seems they knew what they were talking about

Or maybe they just said that as both are yellow
Absolutely that the ancien Axtect knew it very well before the West.
if you guess long enough some things are bound to be true
the animation is so adorable
+oldcowbb The lead getting shot into gold...how cruel
+Wilson Ong i see elemental torture
+oldcowbb they really do take their time doing these videos e-e
^above me
LOL LOL LOL!! TED with a PLUS sign
also my grand mother told me that in million years long time ago they were old but they find golds and they hide the golds because it when they died people will not gonna found the golds
This video ends on such a happy note.
"Oh, and if a star dies close enough to us we could either get rich or completely die out!"
so basically forced russian roulette
Stars massive enough to explode in a supernova are too far away to kill us with their explosion
Beetlgeuse is the closest star that could explode in a supernova and it's 600 light years away so it won't kill us
Now the problem is that a neutron star can hit us with a gamma ray burst instead which will kill us too .
fair
Spoiler alert
@@unwase woah we already too many problems on 2020.
Well done. When the very young earth was still forming and molten, most of the gold that arrived settled deep within its mantle and core because of its relative weight and although moderate amounts of stirring have occurred, most of it is still down there. Occasionally volcanic activity lifts some into the crust mixed with many other heavy elements (magma) and even some of it rarely makes it to the surface (mixed in the lava). Additionally, cracks in the crust (earthquakes) permit hot acid water to flow toward the surface, slowly depositing dissolved minerals in these cracks (such as quartz and gold) as it cools. Most quartz and hot water veins sadly brought no gold with it (those quartz veins are called "bull" quartz) and sometimes this hot acid water flowed toward the surface too fast (steeper angle than 67 degrees) to permit the gold to settle (precipitate) out and it remained diluted in the 3 to 5 parts per million concentration. So, every time you hear of an earthquake deep within the crust, just think more gold may be heading near the surface for you to find some day.
Would there be solid gold asteroids out there? Blobs ejected from supernovas?
Just as long as when you hear of an earthquake deep within the crust, it's not below the 221 mile range, as Japanese researchers are discovering. Below that the lava compresses and heads for the core. (Crossover Depth)
@@canadiankewldude What an interesting concept. Totally new concept for me. I wonder how truly heavy elements, such as uranium, ever make it to the surface?
@@richardrobertson1331 Z-Pinch was first produced in the lab in Ukraine and repeated in American labs.
Their research is available online, the elements in the same percentage as is found in the ground.
They have discovered and published that super nova are not powerful enough to create the elements from Iron onward.
Two notes. First, to the best of my knowledge, the majority of gold and other heavier elements in the universe is produced not in supernovas but in much more rare events - neutron star merges. Second, all gold that we mine actually came to Earth on meteorites over billions of years of its development, since the original gold, platinum, and other heavy elements present during the formation of the planet should have sunk into its core.
I was about to comment the same
@@AhmedAshraf-pd7mu Even me
this sounds a lot more likely and also explains how there are significant sized nugget finds on the surface - which would not happen if that gold was delivered as dust (or to an ancient molten planet) then re-precipitated from solution. That said, some of those meteorites must have been huge?? if they were themselves not entirely vaporised on impact ?
According to James lovelocks book, the revenge of Gia, 4.6 quad trillion tons of gold and platinum, resides at the earth’s core!!
That sounds fine, but the biggest problem is your so-called "knowledge" is simply theory based on someone else's imaginative ideas that seem to reside somewhere deep within your own imagination. The fact is you, you or authors of books have no clue whether or not the gold we find comes from meteorites, nor do you have a clue other than "gold is heavy" whether or not there are trillions of tons inaccessible in the Earth's core. I'll listen to your theories, but please do the rest of us a favor- don't continue to pull fairy farts from your rear ends and then have the audacity to claim they are nuggets. 🤦♂
"Diamonds have been crushred for like a million years."
"Gold is literally made from space explosions."
All the elements in you heavier than hydrogen were created or dispersed by a thermonuclear explosion. Romantics like to say we are made of star stuff, or star dust; a cynic would say we are made of nuclear waste. And it was really very radioactive stuff. It had been subjected to neutron fluxes as high as a mole of neutrons per square cm per second.
The earth has only been in existence for 6000 years
he meant to say 60 years
Abigail Jo facts, no joke! 6000 not 60 ✌️
I'm telling you it's 60, i read it on the internet
"Did you know that gold is extraterrestrial?" < well it's been on earth since it formation billions of years ago, so it's as "extraterrestrial" as we are, or anything on earth actually.
+Guss De Blöd Since BEFORE its formation even.
+Guss De Blöd not everything on this planet was here when it was formed. Water for instance came eons after the planet was formed
Sebastian Ferguson
I'm talking about elements, not molecules.
Some may be from outer space, but most are here since the beginning.
+Guss De Blöd even if it has been on earth for trillions of years, it has "EXTRATERRESTRIAL ORIGIN" thus it's extraterrestrial.. kindof a no brainer..
*****
So does everything then , as the atoms that are on earths existed since before the earth existed.

This was excellent and beautiful. One interesting side note, attempting to make gold this way will most likely contaminate it with radioactive gold as well. This is one way you would know it was "manufactured".
Au-197 is the only stable isotope, and there are many radioactive ones. If you were to transmute some other element into gold, you'd very likely have contaminated any gold that you made with radioactive isotopes of gold.
Some ancient cultures believed gold to be from the remains of their "gods", also known as the fallen angels.
I was just reading about the Annunaki
am i the only one who felt bad for the alchemist
aye dumbass gold originally comes from Africa

I think they are missing the more important question: could Scrooge McDuck really swim in one of those Olympic swimming pools full of gold? Sadly, the world may never know.
The answer is no. It would be solid, like a floor.
yes he can
He could but it's hard to swim in solid, I think I'll stick with liquid
Dude if you want a response just watch Mat Pats video on it
That's cos man is too stubborn to let research carry on in Egypt I bet they know what the purpose is of them just no one is saying what's the truth behind them only the Cat Goddess can reveal that Men are from Mars Women are from Venus👑🌏
Beautiful story! Humbling to think that a gold necklace came from the heart of a dying star.
Poetic
Informative video. The end part of this video shows a distortion of our disconnection; giving something worth due to rarity and assigning it a monetary value at the cost of disruption of ecosystems and potentially causing bloodshed (wars and infighting because of the lust for it).
I think we need to recognize that living systems are worth more than applications and value in the materialistic sense, that we give these wonderful byproducts of important celestial bodies that give life and light through its own energy, temperance and respect, and in turn receive it.

5: Gold
6: Lead
7: Uranium
Wow 😮😯😲
Wait, why would is skip around like that? Shouldn’t it just gradually go up the periodic table? And why argon after iron? Argon is much, much less dense than iron.

"Gold is Extraterrestrial" - If you're going to put it like that, everything is extraterrestrial.
Yes. Gold is a low vibration energy/light solidified now. Just like many metals & other rocks.When you could reverse gold back to light again than......💭☝️✨?
Quartz also holds the key to it.
But this is a way higher science.

@@rexluminus9867 basically, you're talking bollocks
"Gold is extraterrestrial" Isn't everything cooked up in space?
Meaning it isn’t produced on our planet.
@@francisbright7872 nothing is produced in Earth, everything comes from outer space. Even you
@@alial-ajmi7415 Ah yes, I always knew I was born on Naboo.
@@alial-ajmi7415 This is actually not true. Helium is produced on earth from the decay of Uranium. It's so inert that anytime it forms it just flies off into space to join the interstellar medium.
@@setcheck67 But there would be no helium if not for uranium, which comes from a supernova.
what if people in the future no longer considering gold as a valuable substance? like what if people value dirt/soil because of the nutrient in it to make plants?
+Raiden Noeramrin Well then they will value soil above gold. What of it?
+Raiden Noeramrin I don't think they only mine it for its wealth, well that's a big part of it, I think it's mined for building stuff aswell. :P
+eh dollet Close, gold is an excellent conductor and is used widely in electronics.
+Raiden Noeramrin Gold is an incredibly useful material! It's soft & malleable so it can be made into whatever form we like, it's highly conductive & it even has properties that allow it to shield people from some of the harmful effects of radiation. In fact the outside of the lunar lander in the Apollo missions was covered in gold foil & even today almost every electronic device you've ever had has had some gold in it.
wow, i never heard that before. seeing all these smart people in my comment make me feel like an idiot :/

No no no, this video is all wrong. Supernovas dont create gold. Not enough power. Gold is created by neutron star collisions.

John C Gibson how do you know ((( not trying to start a argument)))
Three swimming pools? that's it?? I find it hard to believe...
3 Swimming Pools = 7.500 M³
Gold density = 19,3 g/cm3
1 M³ of gold = 19,282 KG
7.500 M³ of gold = 144.615 KG
maybe it's correct.
Various say there are about 155,244 tonnes to 2.5 million tonnes of gold circulating and in storage. That's still a drop compared to all gold LOCKED AWAY in the core. There is enough there to cover the earth's surface in depth between 1.5 feet to 12 feet thick.
Me too. Specially since this includes all the gold the Egyptians mined, all the gold the Aztecs mined, the 1800's gold rushes, the vast treasuries of the ancient kings and queens of England, Hebrew and ancient kings and queens, Japanese emperors, and the gold that has come from modern strip mining methods. Then count all the gold that is in private hands, all the jewelry in modern times. All the gold in Fort Knox. Then count the gold that is in electronics, which is a small amount but a lot is used. That's a lot of gold, and I find it hard to believe that all this would fill a measly 3 swimming pools.
Firsty kid, half the gold was robbed from one country to another, 2nd gold is so small that peas are bigger then what is really found, its not like in the movies &3rd jewerlly its 100% gold hence 24crt gold, &it you think abt it, condence the gold so theres no space (liquid gold), & when they pool, there are talking about olympic size pools, it makes sence, Fort Knox is Nazi gold which is really spanish , indian, and cowboy & indian gold. &remeber gold is stolen & resold by crafty jewlers
I'll have to agree, what of those Mosks that have those huge golden domes? even melted down into bricks, that combined with all the rest the gold would have to take up more than that.
THE MUSIC FOR THIS VIDEO IS JUST ON POINT!
Best animation with superb comic angle to it.
Voice, animation, content beauty of this channel.
So that’s where gold comes from! I wouldn’t have guessed that in a bullion years.
Well, now you no.
Falcon Quest *know
@@TGoodie1717 That's the point.
Clever
About 4 years ago ‘They’ claim that most gold are produced during hypernova (exploding neutron stars).
As a side note it seems much of the time gold veins are located within Quartz formations. If you find a sizable quartz rock laying around always worth a look to see if there is any yellow in it. While very rare this is actually a way to find gold just laying around on the ground.
This information may or may not be useful, but good nonetheless
I got out of my car about 3 months ago and there lying on the ground was a 14K gold chain.
I had it appraised. 2,200 dollars. It is 89 grams. Good find.
The clasp was broken. Had it fixed for $78

1:09 Im thinking of eggs right now...
+Kevin Larsson my two eggs.. ?
FuOnY How did you know? xD
The video makes it sound like gold is just iron with a bunch of extra neutrons. I think it left out the protons.
And electrons.
+Prelude610 Agreed, the animation was kinda misleading
+Living Lifeform The electrons are kinda trivial. You can kinda just throw a gold nucleus out there and it's gonna take it's electrons from other molecules spontaneously where as it takes special conditions to produce the nucleus itself.
+Prelude610 It's possible for a neutron to turn into a proton and an electron pair. This is known as beta decay and happens in unstable nuclei such as the neutron rich iron.
Daniel O'Connell
It's not an electron pair, it's one electron and an electron-antineutrino. The problem is that in the animation it looks like an iron atom with many neutrons is suddenly a gold atom, which is not the case.
I gold prospect up in Maine. I find gold often. I love it. Not just its value but there is something almost other worldly about holding Gold pieces. Truly a marvel and Mankind's greatest mystery. 🙌 I love gold panning. 💛
Appreciate the animation.🤗

"Maybe some future supernova will occur close enough to shower us with [gold] (wohoo!)... and hopefully not eradicate all life on Earth in the process" (Boooo!). That escalated quickly T_T
It will kill us all because of the explosion
@@steveyt1392 no, cause of radiation
@@joshchristopher551 heat
@@steveyt1392 stop, my major is Physic, the nearest dying star is very far away, supernova occurs a massive explosion, this explosion is radiation, this radiation includes heat, some elements ( neutron, electron, proton, even photon... ), and deadly Gamma Ray Burst, the heat radiation has long wavelength and since the dying star is very far from our Earth, we wont be able to recognize the heat, and mostly doesnt effect us that much, while the most deadly thing is Gamma Ray Burst, we will be dead for sure
There would be no point of gold if there was a lot of gold on earth, its prices would drop below the price of lead.
