Where Did Water Come From?

- Mercury, Venus, and Mars are all super low on water - so where did ours come from and why do we have so much of it? We think our water came from a few unlikely sources: meteorites, space dust, and even the sun.

Well, you see, when two hydrogen atoms and one oxygen one love eachother very much...
A wild, molecularly unique throuple
Then a stork flew in and delivered a water molecule
Hydrogen wants to bond so badly it's less love and more a shotgun wedding where that poor oxygen is forced to take both those hydrogen consensual or not.

Blood..not water
Except that's not the phrase 😅 It's "can't get blood from a stone" 😊
It's been a unique frustration of mine, always hearing that "Earth's water came from space," but never with a reason provided. THIS was the explanation I have literally been waiting many years to hear. Okay, THIS makes sense to me now. This is such a great video.
Congrats?
Makes no sense to me. Why was earth the only planet that this process occurred on?
Whoa whoa WHOA, how am I just now finding out that most of Earth's water is locked in rock, and up to 18 fricking times the amount in the oceans? Holy crap, I thought I knew stuff about stuff but I am humbled. This video also finally made me fully understand how impacts brought so much water to Earth, the key piece of information I was missing is that the Oxygen was already there! Big thank you for this one, Eons, love u
there's a ton of water locked inside us as well
@@LuisSierra42 right but if I'm not mistaken essentially all the water attributable to living organisms had to have originated from inorganic precursors, it's not like living organisms spontaneously produce excess water (where would the elemental hydrogen and oxygen come from?), we are made from it, use it in various metabolic processes, and recycle it.
@@LuisSierra42 to put it differently, you could say the water locked in the biomass of living organisms on earth is just a subset of the water locked in minerals, derived from it after the biogenesis event. How much additional, genuinely new water has been produced by life in the elapsed time since then is a question I hesitate to guess at, but would love to learn more about
It makes me imagine squeezing a giant peridot (Olivine crystal) like it was a lime.
Also, as the Earth cools, more water is being reabsorbed by the rock. Our oceans will dry up and the planet will be like Mars. I am not sure if this is supposed to happen before 600 million years from now when the Sun will be so hot it will boil all the water off anyway.
She said Mars has no water in this episode, but it actually has quite a lot stored in rock, just like Earth. However, Mars' core is dead and all the water has been reabsorbed. It did have surface water and likely oceans at one time.
This is the best Earth Water story that I have ever watched, even from cinematic space documentary series and cable channel productions. Other documentaries about the origin of water have a feel that the film makers didn't understand the details, and so skipped over most of it. Eons talks about the early sun, gravity, heat, pressure, MINERALS, time limits, and most importantly the acknowledgment that billions of years have affected the evidence left for us to study today.
Also vulcanism
It is amazing what more people could know if they could just lose a little bit of their adherence to myths.

@@charlesbaldo Huh. That's really interesting. I wonder why they stopped teaching this if they knew about it at least as far back as the 60s. Unless some scientist decided that it wasn't true by the 90s.
Actually, earlier. Because I graduated in 93. And I wasn't taught it in jr high either. Weird.
Interesting what they were teaching throughout the generations, too. We did have sex ed in high school in the 90s, too. I remember the kids being embarrassed by it. I'll bet they know all about it much younger than that now. We still had home ec back then, too. I wanted to take wood working, but as a girl I was forced to take sewing instead.
Do kids get tattooed that young now? I don't remember ever having seen a tattoo at that age. And I was barely allowed to have my ears pierced back then. Little did we know all the piercing we would see on people now.

The more you learn about how the earth formed it just feels seems more and more improbable. The fact that we exist means these series of improbable events did happen. But the more improbable we find it to be the less likely that complex life is common outside of the solar system. It will be truly fascinating to learn of another life form one day and how they formed.
Yes, complex life (let alone sentient with the ability to create, not just Think) is likely extremely rare.. not a scientist but would just throw one in a million out there and have someone tell me I am optimistic.. then there is "come and gone" with "wait for it.." making a meeting pretty unlikely.
Having a moon and tides is possibly the greatest example of "dumb luck" that our little arm of the this galaxy will ever have.. at least as far as complex, somewhat creative and vaguely sentient life is concerned.. 😉😃
Be Well!!

The life itself is both a miracle and the most horrible thing ever, constant war for resources.
Yeah, like shaking a puzzle in a box in hopes it solves itself, i just watch these type of videos as a hobby, because they are interesting and to learn about things but seriously, having a magnetic field, the right distance to the star to mantain liquid water and way more stuff that makes the planet like it is today, its fascinating, makes me wonder what is going on in other planets in the universe.
@@cristianfr3410 ever heard of “survivor bias”? Look it up, it explains why these arguments about “extremely rare therefore highly improbable” are fallacious.
Very roughly, think of a lottery. You as individual have say one in a billion chances of winning but as the pool of people who buy tickets is so large, someone winning is not only not improbable, it’s expected.

I can get that same kind of feeling from multiverse theory, or, at least, the popular idea of it. Try and picture an infinite array a possibilities, from whether you put on a different shirt this morning to whether Earth never cooled enough for our kind of life to exist, leaving sentience to emerge from, like, interconnected networks of extremophile bacteria. Of all the many ways the history of our planet could have been different, we ended up with the one where we exist, right now, talking to each other. Right now, we're creating that history, and that future, navigating through a tiny, barely-perceived part of an infinite web of possibilities. Life's amazing, is what I'm saying, and it's a miracle it even resembles something familiar.
This makes more sense to me than any other water origin explanation. THANK YOU!!
I am not sure if asteroids are the main source for all the water. Think of how much water is needed to make up all the oceans.
@@luudest well, there were waaaay more asteroids back then, and we were hit with them for quite a while

I have a hard time believing the accuracy of these videos that go back millions of years ago...
Two things scientifically deeply intrigue me. One is time, which doesn’t actually exist, the other is water. Water is a polar molecule, hence it is a liquid at temperatures when it should be a gas.
The probability of us even existing is mind blowing.
The odds have to be in 100s 😂😂
On the flipside, think about the billions of systems that almost were right for life but weren't. It was bound to happen somewhere
No, the probability is 1:1. We exist.
It’s the same as the probability for anything else existing

I always asked myself "how could water form if after the collision with Theia the earth surface was so hot"? Luckily I got my answer
Actually she got it slightly wrong. It's not the Pressure it's the pressure of water vapour alone. Each evaporaiton/condensation pairing depends only on it's own pressure as a gas compared to it's temperature as gas and liquid. If we said filled the atmosphere with Argon (which is pretty much intert) we'd not see a drop more rainfall.
Thus it's because Earth was so hot after it's colision with Theia that the water vapour pressure could get so high, it was so warm it kept evaporating water even at super high pressures. Until the pressure got so high or the temperature dipped low enough that this equilibrium started shifting the other way and condensation overcame evaporaiton.
It's why if we sent water the venus it would not fall as rain, because hwile the Pressure there is likely a lot like the hadean period, it's relative pressure for water vapour is low because if the lack of water in it's atmosphere.
What happened to Theia?

Water is so stable there is a high probability that the last glass you drank had molecules that were previously drank by several famous historical people. We will skip that part on how it left them. 😮
Didn't Dawkins talk about "the bladder of Oliver Cromwell"?
Actually if you go into organic chemistry you'll see water giving up it's hydrogens and picking up extras (to later relase one of them at random) quite a lot. The destruction of water molecules is rather rare yes but it has quite a lot of turnover in the hydrogen atoms.
It's more correct to say that the oxygen atoms involved in water tend to stay as part of water, the hydrogen atoms are more fickle.
@@DaDunge , I think that’s more general/inorganic chemistry, especially in acidic solutions. Most organic compounds are hydrophobic, and reactions are carried out in nonpolar aprotic solutions. Peace
@@cps_Zen_Run Eh what? No most naturally occuring organic chemistry is hydrophillic. It's when we synthetize things in lab we work with hydrophic conditions to speed up reaction times.
@@DaDunge , cellulose is probably the most common natural organic compound, and it is insoluble in water, as are hydrocarbons, fats, so I respectfully disagree. I taught organic chemistry and biochemistry for several years, but I could always be wrong. Peace. Feel free to have the last word.
I thought water originally came from the earth itself, I never thought that water came from extraterrestrial meteorites that hit the earth several billion years ago. This is very cool and adds to my insight into the history of water formation

Space. It all came from space. Everything. There is nothing on earth that didn't come from space.
And we will be recycled in the same manner. To the next Sun and planets.
The rock at 3:48 looks like it is just daring you to try to get its water.
So a glass of water that I just drank is 4 billion years old? Holy cow.

@@AndrewTBP that means I m too ?
Mineral/spring water tastes so delicious compared to recycled tap water.
The best mineral water i ever tasted was in the scottish highlands. It had a slightly bitter, brackish taste. 👍🌱⛰️
The actual water itself is probably disappointingly new. Tap water was probably made at some treatment plant somewhere recently. That bottle of spring water you bought at the store is much older, though I doubt 4 billion years old. It likely fell as rain at some point and drained down through the soil to the spring.
@@kalk5845 YEAH, just think, you are drinking the same glass of water that George Washington drank.....
Very interesting! When I was young, I learned that our water mainly came from comets, mostly during the Late Heavy Bombardment. But this video doesn't mention the LHB at all. What changed?
I recall from another utube channel that the Late Heavy Bombardment might have not happened at all. Somebody doubts that period of history.
@@keithfaulkner6319 In fact, it was a conspiracy theory from the Heavy Water Lobby...
@@keithfaulkner6319 it's not outrageous to assume that perhaps we don't really have a particularly clear and accurate idea of all of that time. But actually something like a billion years of more frequent asteroids isn't really a crazy idea either.
@@tsmspace totally agree. But the LHB was supposedly a much narrower time period.
Please understand i'm not advocating either way. Just saying what I heard.
There's also a theory that Theia, the protoplanet that collided with Earth that they were speaking of, is the one that brought water to Earth, since, in theory, in formed in the outer solar system, and could have been comprised of much more water than early Earth was, considering the Moon also has a decent amount of water locked away as well. I'm surprised they didn't even mention this theory during this episode :(
They also don't mention how mars also had a lot of water at one point.
I'd like to know, what happened to Thea? It was a Mars size planet, how did it disappear without a trace? Should it not be orbiting the Sun? Earth didn't get knocked out of orbit, neither did the debree that latter became the moon. So what happened to Thea?

Thx 4 sharing. Plz make alot more new ones.
Why was the atmosphere so heavy, and why did it (relatively) quickly dissipate to the equilibrium it's maintained since? Would love an episode about that. Where the gasses came from, how they accreted/accumulated, and why earth lost that pressure the way it did.
Exactly. Made me think of the same question:
Now they made me think of another question: how did the earth lose the 215 bars of atmosphere in one age (we're down to 1 bar now)? Was it massive solar wind after the faint young sun (paradox) became hotter and more active?
Took place over a half billion years. Not sure I'd call that relatively quick even in Geological terms haha
@@whiffyclarke no. More like 5 trillion years!!! Scientist love to throw big numbers when it comes to the universe when in fact its all a theory at best

Dari video ini dijelaskan secara mudah untuk memahami terbentuknya air di bumi. Penjelasan rinci dan contoh dari kehidupan sehari-hari diberikan. Dimulai dari Hadean dimana bumi masih berupa bola pijar yang panas dengan suhu yang sangat tinggi, pada saat itu juga terdapat kornet, asteroid dan beberapa planet lain yang telah terbentuk. Ada beberapa cara air bisa ada di muka bumi, misalnya sejenis meteorit bernama Chondrite yang berisi air. Dan terjadi penguapan oleh beberapa bahan yang mengandung CO2 dan kemudian turun ke bumi. Ini digambarkan sebagai uap air yang mendidih karena suhu tinggi. Oleh karena itu, bumi sudah lama mengalami suhu dingin yang disebabkan oleh beberapa faktor seperti waktu. Dan bumi menjadi seperti sekarang dengan air melimpah di permukaan bumi. Video ini sangat bermanfaat bagi kita sebagai mahasiswa Geologi.
The video makes a fascinating point about the origins of Earth's water, suggesting unexpected sources like meteorites, space dust, and even the sun, shedding light on the mystery of why our planet has so much water compared to its neighboring planets like Mercury, Venus, and Mars.
I love how this episode goes far back in time and way beyond the usual paleo centric info we usually see. Chemistry is NOT my strong suit but I'm convinced Kallie can teach me anything and I will learn it.
I remember watching a science fiction show years ago where, as part of terraforming Mars, comets had their orbits adjusted so that they would crash into Mars. Since comets, in the outer solar system at least, are basically dirty snowballs, that might not be a bad idea. You just need to be careful you don't accidently crash one of those comets into Earth.
You'd still need to vapourise them and at the moment Mars doens't have the atmosphere for rocks of crystalized water to vaourise them. Venus might.
OK--so now work out how many comets it would take to terraform Mars, and how long it would take a comet at average speed to get here from the Kuiper belt.
In reality it's a bad idea. Today we know that there is a lot of water on Mars, enough to create a shallow ocean. So there is no need to use comets
Comets crash here all the time
Sounds like a B movie plot, because you just know that one of the comets is going to escape and end up on a collision course with earth.
This video is truly impressive and opens a window of insight into science because it tells the history of the formation of water, starting from hot temperatures until the earth's temperature changed to cold. This video really inspires our mindset
That was a lovely, jokey, smart and actually scientifically informative session. Well done!
These theories don't explain why Venus and Mars lack water. It's odd that this is mentioned right at the top of the video but then never addressed.
We can suppose that Mars had water similar to Earth, but that it lost its magnetic field and most of its atmosphere, with any water boiling away to space. But I don't think this explanation works for Venus, which still has a very dense atmosphere.
This is my question as well, since presumably Venus and Mars would be subject to similar bombardment to Earth.
Maybe cause Venus is too close to the sun that the pressure was not enough to prevent the water from being evaporated and blasted away by solar winds and its magnetic field
Planets are dead stars.
When stars cool and shrink they turn into planets.
The water was produced here on Earth.
.
This model explains why earth was once super hot (it was a star)
And it explains why earth was also once covered in water.
Earth used to look more like Neptune.
In the future it'll look more like mars/venus and eventually the moon/mercury - once earths volcanic activity stops regenerating our atmosphere, the oceans have evaporated and the atmosphere blasted away by solar wind.
AHHHH! Drinking Star Water from a Space Coconut!! =oD
This explanation really helped my insight, because I could know that water does not come from the Earth itself, but through a long process for water to exist on Earth and this process started 4.5 billion years ago.
Does this story of how water got on earth mean that habitable planets in the goldilocks zone is actually more rare than we think?
I never knew that the same event that led to the formation of Earth's moon was the same event that allowed water-carrying meteroids to melt on Earth. The moon is more linked to Earth's oceans than I thought!

The more I learn about the Earth the more I think that life must be rare in the universe, as the chances to get suitable conditions to support it seem unlikely.
But theres infinite time and chances
Thanks for creating this content. Very useful content, especially for me as a student majoring in geological engineering. I was able to find out further that the water on earth originally came from a meteor that hit the earth millions of years ago. It can also be seen that dust caused by sunlight contains hydrogen and oxygen which then interact with each other to form water (H2O). Really adds insight!
It came from the sun, the third rock from the sun was positioned exactly were it can collect the disk vapors, and continues to collect to this day.
With how drastically different earth's atmosphere has been over time, I can't help but wonder how far back in time someone could travel before just stepping out of the machine and breathing the air would kill them.
Great video! Very informative. Follow-up question if anyone is inclined to answer: If our water came from asteroids, why isn’t there a similar amount of water on Venus? I’ve read that Venus is very dry, so what accounts for the difference?
Watching this video was eye-opening. The journey of water, from its cosmic origins to its presence on Earth, is truly captivating. Understanding the origins of something so fundamental to life on our planet is both humbling and awe-inspiring. Thanks for sharing this enlightening exploration!

This video was very useful for me, I learned about the origins of the formation of water that we use every day in our daily lives.
Some of the information in this video was absolutely new to me!
What a heavy episode, but it ended on a light note! Can't wait for the Epoch changing live stream!
This is an outstanding video. Your narration is excellent and the information provided is interesting, informative and engaging. Very well done!
"One does not simply walk into Mt. Everest"
3:10 whoever wrote that line in the script is definitely awesome 😂
soon they will have to make a video and call it ''where did the water go?''
