New Supercomputer Simulation Sheds Light on Moon’s Origin
ฝัง
- เผยแพร่เมื่อ 3 ต.ค. 2022
- A new NASA and Durham University simulation puts forth a different theory of the Moon’s origin - the Moon may have formed in a matter of hours, when material from the Earth and a Mars sized-body were launched directly into orbit after the impact. The simulations used in this research are some of the most detailed of their kind, operating at the highest resolution of any simulation run to study the Moon’s origins or other giant impacts.

What’s always so mind-bending about planet collision simulations like this one is how fluid the impacts are. It’s more like two water droplets splashing together in space than most people would expect.
The best thing about states of matter is how similar they can act
Solids at very large scale will appear to behave very similar to a liquid.
@@Braindead154 in this case early planets including earth is technically liquid (magma) not solid, even until now it's still mostly liquid
From the planet's point of view, the only states of matter that actually matter (pun intended) are liquid and gas. The scale is too big to see solid structures acting... Well solid
I suppose it’s like a land slide you see coming down a mountain and you see solid rock acting like a liquid
Wow, those fluid dynamics are amazing. Crazy to imagine the real impact.
Guessing its only a matter of time before one is on our little screens.
The shockwave from the impact almost blew the South pole, on the opposite side of the planet, off into space, but not quite.
@@Gabriel_McMillan What if the smaller planet did not crash into the north pole ;)
@@martinfehringer6408 Indeed. Nevertheless, the effects would be mostly independent of where it impacted, at least in terms of the way the shockwave would be transmitted throw a spherical planet-ish body.
However, you do raise a very important point. While the shockwave would transmit through the planet, almost causing a planetary-scale spalling of the opposite side of the larger planet, on the opposite side from the impact, regardless of where the smaller planet hit, the effects would be dramatically different, in terms of how the debris would scatter, and where it would fall, if it had hit squarely on one of the poles, rather than close to the equator, which is more like what it looks like in the model The debris pattern might change in such a way that it could alter the extent of the spaghettification of the smaller planet's core, like what we see in the model. Or, if it were a more direct hit, rather than a somewhat glancing blow, it seems that the smaller planet's core could conceivably have impacted our own core, perhaps contributing to the Thorium and Uranium content of our own core, which may have been why our core did not solidify, and why our magnetic field still protects our atmosphere and our DNA from solar rays, while Mars' solidified probably billions of years ago, causing it to lose its oceans, perhaps? Whether a more direct impact would have resulted in more or less of the heavy metals being near the surface of earth, I do not know. I'd suggest asking a supercomputer that same question, though. If it impacted in-line with the spin of the earth, this could have drastically decreased or increased the rate of spin of the Earth, perhaps indefinitely. If it did hit closer to one of the poles, perhaps this might partly explain the tilt of Earth's pole relative to our orbit around the sun, which is responsible for the seasons, which could also have played a major role in the evolution of life, and perhaps even the emergence and the survival of life.
Whatever the case may be, I believe all of the extremely rare relationships between Earth and our one disproportionately large moon, which is so kind as to change the tides for us every few hours, for the past several billion years and counting, and to have donated a few gigatons of its own flesh to our surface, and thus to our primordial seas, and to our volcanic rocks and thermal vents nearest to the surface... this all adds a great deal of credence to the rare earth hypothesis, in my opinion, and explains why life may be quite rare in the universe. Not to say unique, which is certainly not the same as rare. I'm sure there is a great deal of life in the universe. But I suspect this is the reason why we do not have dozens of alien species on dozens of different alien outposts in our solar system, transmitting their TV stations to Earth as we speak, because, when we look at the galaxy, with Hubble and James Webb, as rare as G type stars and rocky planets in the Goldilocks zone are, it is the nature of our moon, and what it gave to earth, and how it would have accelerated early organic chemistry, and exponentially increased potential chemical combinations that may have given rise to life, which seems almost unique, based on the relatively small subset of exoplanets we've seen so far. While that subset of exoplanets is small, relative to how many are in the galaxy, I believe we do know enough about a hundred or so exoplanets to know that the ratio in size of that of Earth to the Moon, and their orbits apart, are indeed essentially unique, especially if we exclude gas giants and planets orbiting as close to their star as mercury.
This tells us that life may be more precious than we'd imagined.
It also tells us much more about where to look for life. We need to look for a G type star, with liquid water, and a moon like ours, which creates tides, on a planet with some continents and some oceans. If we ever find another such planet, that is where I would focus my search for life, with my interstellar Von Neumann probes, and the like...
That being said, those calculations would all change dramatically if we were to find a true second genesis on Mars or one of the moons of Saturn or Jupiter. I get the impression that we probably did find life on Mars recently, but NASA can't say so yet, until and unless it gets the samples back. However, we have to be extremely careful to determine whether it is a true 2nd genesis, or, as I suspect is far more likely, if life spread from Earth to Mars, back when Mars had liquid water and a magnetic shield, with a much thicker CO2 atmosphere, which would have been very friendly to certain spores, seeds, or bacteria which might have been transmitted from Earth to Mars by an asteroid impact, followed by the solar wind scattering bits in Mars' direction, or if some of the debris happened to fly in that direction. Or, perhaps life came from Mars to Earth originally, but was unable to survive on Mars. It will be impossible to say without the samples, and even then, it may still be impossible. It could be difficult to say even after decades of manned archeological research on Mars. Whatever the case may be, please be very careful with those samples, NASA. I suggest examining them at an orbital laboratory, before bringing them into Earth's atmosphere, just in case, because there are just so many unknowns, since it appears there was indeed life there, based on the recent sample data, the aromatics, and the like. Since the potential worst case scenario for all life on Earth could, conceivably, be absolutely catastrophic, it is best to proceed with the utmost caution, even if the likelihood of there being anything that could germinate out of a sample, at this point, would be very low. The danger, I think, is somewhat less low than some may expect, because if there was life on Mars, and it died out as the oceans evaporated, the magnetic shield failed, and the stellar wind blew the atmosphere away, then the odds are, it had a billion years or so to evolve under those conditions, and it is impossible to say what adaptations life may have come up, in response to such extreme stimuli, given a very large amount of time and opportunity, and a strong will to survive. Perhaps it is resistant to hard radiation. Perhaps it can survive in very low pressure. We just can't really even begin to imagine. Let's examine it in orbit, just because we can, and because it will reduce risk, please. Why wouldn't we? Won't that also reduce the risk of us losing the samples in reentry before anyone can ever get a close look at them? I suspect we could build a very sophisticated, remotely operated, orbital laboratory, for this purpose, over the next few years, if we put our minds to it, long before the sample make it back.
@@josephmastroianni1560 I sure hope so, that would be awesome!

We all learn new things, no shame.
@@dae2530It is science.
The insane part of this you don't get from the video is that this didn't happen over a period of millions or thousands of years, but just 13 hours. That is absolutely wild when you think about it.
Really? Thats insane. Imagine if you could be there and watch it
That's freaking less than a day!! Little over mid-day, I can't believe it! Thought it's a simulation for a few thousand of years at the very least! ... I can't believe unless I actually watch it with my own eyes lol ... How can that have happened that fast! 😦
Prove it...
Yeah, so wild it sounds fake. 😂
@@zeitlichkeit5094 the universe tends to do that. If it hasn’t left you scratching your head over seemingly simple mechanisms, you don’t understand enough about it
I have never seen a simulation like this one and the fact that this is not unusual in the universe is mind blowing.
The Earth and the Moon collided, but this video is worthy of a Disney animation.
Here are two scenarios in this film which show two collision scenarios between Earth and Moon th-cam.com/video/CI2P3jzyftI/w-d-xo.html. The Earth and the Moon are not disintegrated and each body keeps the traces of this collision.
This collision between Moon and Earth is distinguished by the observation :
- huge impact craters (on the Earth - Tibet, and on the Moon - Mare Orientale)
- the earth's crust divided into plates,
- of a particular relief compared to the other planets,
- the desert relief of the Gobi in the Sahara directly linked to the giant impact crater in Tibet, represented by huge landfills of the lunar soil and other desert areas
- volcanoes and mountains far from the edges of the lithospheric plates and those along the edges
- huge ruptures of lithosphere represented by magma flows released in the Pacific, Indian and South Atlantic oceans
- chains of earth crust projections seen at the bottom of the Pacific, Indian and Atlantic oceans
- chains of earth crust ejections seen on the ground, like the summits in Africa
- traces of the tsunamis which followed one another following the collision, represented by ripples at the bottom of the ocean at the places where the magma came out along the said "ridges"
- "damaged" lunar relief seen by the South Pole-Aitken basin
- eccentricity of the lunar relief because of its discharges on Earth and which determines a fixed position of the Moon with respect to the Earth, represented by visible face and hidden face
- the periodic inclinations of the rotation axes of the Earth and the Moon
- the plane of the lunar orbit inclined with respect to the plane of the earth's orbit
These are direct consequences due to a mechanical action by the impact between the Earth and the Moon.
The theory of continental drift is wrong and the classification of geological eras is also wrong due to the jostling of the earth's crust during the impact and the mixing with lunar soil, which itself has another age reference. .
Fossils, such as the skeletons of dinosaurs and other animals, coal, oil, gas, are entities that are consequences of this collision.
Actually this collision could be very unusual in the universe. We have no proof that this kind of Planet-Moon formation happens with any degree of regularity. This could be very rare indeed where a collision like this begets a Planet and a single very large Moon. And that could be why life on Earth is what it is and very rare indeed.
@@georgespalding7640 Thank you for your clarification, man. I love astrophysics but I still have a long way ahead to learn and understand what we know so far.
From my astronomy classes I've learned that the size difference between the moon and the earth is actually pretty rare from what we've observed. Most terrestrial planets either don't have moons or have relatively small ones. Ours is quite big but so is the universe so something incredibly rare could be happening every second at some place in the universe.
The early universe would have been a wild place full of instability and collisions.

Or so the science boys say, ya know the same science boys that get billions of dollars a year in funding for literally baseless claims and zero advancement.
Meanwhile Elon builds his own "NASA" and has done more for science in 10 years then NASA has done in 80 years. But nah believe NASA they KNOW how it all works right?
We're all star dust.
not at all
If the event happened that is
The water you drank today, some atoms of it might have passed from the first human
What I find amazing about collisions of these sizes is the fact they're so massive that the tidal forces alone are enough to liquify entire planets before they've even collided, watching incoming objects being stretched out as they reach their periapsis mesmerizes me every single time.
Have you ever seen actual collision through telescope lol.
Well, Earth was still melting rock so it helped.

@@gdgd5194 Nah, but Jupiter has a moon slightly larger than ours that gets heated to the pint of having active vulkanism by being kned and deformed like dough from a lot less gravitational force than a planetary colision would have.
If I could have one thing answered in whatever afterlife there may or may not be, I would want to be able to witness these events happening. The sheer time scale involved in planet formation, watching a star ignite from pressure alone, seeing inside a black hole. Space is my favorite thing by far
based
Just buy a lava lamp.
Space needs to be the top thing that every government concerns themselves with. One day the Sun will go red giant and engulf the inner planets. By then we need to be a multiplanet or even intergalactic. As far out as that event is it will take us that long to get there. We need to work on sending unmanned missions to potentially habitable exoplanets, building large ships which mimic the conditions of Earth inside so that when or if a habitable explanation is found we can send a colony. The people who leave here will not be the people who make it there. It would take so long that their ancestors would be the ones to land. All of this would take EONS to perfect which is why we should start NOW!
I feel the exact same way. I want to see galaxy clusters move over time. I want to see the inflation of the universe in slo-mo.
I feel ya
Even better at 0.25X speed
you are correct sir
What's even more crazy is that a single tiny change in that would have changed completly the world as we know it today.
Gotta say the way the earth just went full liquid and you could see the ripples go back and forth was amazing and terrifying and fascinating. I’m gonna watch this a few times more.
On celestial scales, everything is a fluid
@@trbz_8745 but these where actually fluid at the time as magma before the crust formed
@@trbz_8745 to add on it 8f this where to happen now the earth would also act the same way as its nearly all a liquid it would just have a thin shell that would disappear instantly as it shaters
It's terrifying when you realize that even the biggest tsunami in the past decade is barely visible from this perspective if it even is.
@@hubutnotsotao5362 - it wouldn't be visible at all at this scale

Well, it's just a propsed theory. Let's see what the next one will be in 2 years
It doesn't though. It's a probable theory and we have know idea if it actually happened
Two planet size objects hitting eachother behaving like fluid actually makes alot more sense
Fascinating animation. So some parts of Moonearth are probably still flying through space as asteroids?
yes
Certainly! Perhaps not much from this collision so long ago, but in the same way we find rocks from Mars, for example, that were ejected by impacts and eventually land on Earth.
@@NASAAmes would be cool to find rocks from earth on Mars!
Square rock on phobos. People are claiming aliens.
@UCBel3P-fa613JyL678TIQgw your fiction is a lot more interesting than flat-Earthers', but again, it's still fiction
What's really crazy and wild, is when you try to imagine just how horrific and violent the scenario actually would have looked to the human eye.
It would be instant death before the planets even collided because the gravity stretching the planets would cause insanely large earthquakes
It's all relative to size. Imagine a large rain drop hits the pavement right next to an ant. To us it wasn't even noticeable, but to the ant it's far different.
yea but imagine you're in high orbit and you're lucky enough to have all the chunks of the planet miss your space station, altough I'm not sure how the gravity changing it's force and direction so fast would affect acceleration@@musclechicken9036

It's truly cataclysmic. The concept of earth as a sphere with terrain on top of it would cease to be meaningful. The entire outer layer of our planet would be completely scrambled.
I'm really, REALLY glad this happened before life could get going. Also really glad the odds of it happening today are vanishingly small compared to the early days of the solar system.
This must have been a spectacular event. There was nobody there to observe it then but at least we can recreate it now in computer simulations. Somebody should make a VR game from this where you can fly around, zoom in and out, and rewind time.. That'd be cool.

What i like about this sim is it shows that had we had a little more energy in that impact we could have wound up with two moons potentially
Then there, "we" would have never exited.
@@ishwarxion4083 perhaps, perhaps not, I'd imagine life would still develop but we might look quite different having grown on a planet with two moons.

I'm not saying we as humans might still exist, certainlynot as we are now, and while yes the probability of life simply not starting is high, but one thing you must know, and any scientist or scholar will tell you, is that when dealing with "what if" there are no absolutes.
So yes, earth with two moons COULD possibly maybe have had a chance to support life, and MAYBE that life might have reached our level of development. In which case that would have been a beautiful night sky,
But we may never know.
Maybe next time.

Space is FAKE and CGI.
SO F TRUE!!!!
... caught you looking
Just one of the almost infinite number of fortuitous events that were necessary for life to evolve on Earth.
The concept is very easy to grasp.
The fluid feeling seems so off, but the forces at play must be so insanely strong even the toughest matters must look liquified during such an event! Incredible work. It just forces humility on us wee humans
The impact would've melted the entire planet
Gas is a fluid, the impact of the the planet on earth would’ve been so hot that it’d have vaporised a lot of matter and liquified a lot of the rest, which is why it looks so fluid.
@@Clarkey7163 gas is not a liquid. liquids and gases, however, are both fluids.

Amazing as this truly is! Doesn't do justice as to the scale of such an event. What a thing to witness that would be!
If I could I would run simulations like these all day, tweaking minor things to see new results, adding new factors, other planets, bodies etc. the capability of this simulation software is endless; regardless of whether it happened or exists you can simulate it. You should run one of Phobos colliding with Mars, given it’s current orbital decay. Would be nice to have a glimpse of the future, especially since it could release debris toward earth.
Look for Space Engine or Universe Sandbox, one of these may be what you're looking for.
Mars moons are super tiny captured asteroids, and they wouldn't strike Mars with anything the velocity of the dinosaur killer meteor.
you can do it, learn "blender 3D"
Cool story but doesn't decrease the balls temperature sorry let's go Brandon!!
What’s for ? When mars collide with phobos , no humany anymore in the solar system
This is DPM simulation where each particle holds all reality parameters such as gravity, pressure, velocity, etc. All these parameters are established via solving NS, GR equations. Each equation is solved iterative process. As a result, massive computing power and time is required. That's why supercomputer is used, and still this can take 1 to 3 years to get this type of result.
Really? That's absolutely ridiculous levels of computing. I didn't realise such accurate but most importantly comprehensive models and equations could be formed and, no wonder it takes so long.
They dont use general relativity lol, its special relativity. You dont need GR for this, its pointless. And in any case, every particle doesnt model gravity or energy directly, that would take like 5 trillion years to compute. Ever heard of N-body problem? Look at how many particles there is, you cant even see them individually.
"Direct methods using numerical integration require on the order of 1/2n^2 computations to evaluate the potential energy over all pairs of particles, and thus have a time complexity of O(n^2)" In other words, the time required to compute gets squared with every new particle using direct methods. Its not happening EVER with this many particles.
So obviously gravity (and other stuff) here is approximated for every particle, using fast fourier transform.
Ames is so sick, I'd love to work there someday
I would love to have the full real time simulation as like a background effect

At the time the moon was created, the Earth had not yet formed a crust. That's why the surface of the Earth in the video looks like a viscous water droplet.
@@Roo-vy2cI The Earth's crust is only a few miles thick brother. Its like an apple but with a liquid interior. The gravity of the Moon would make it deform until it breaks apart and its like the crust was never there to begin with. The crust being fully formed or not doesn't change sh*t.
@@Roo-vy2cI Even today it's mostly liquid - the earth is more like a water balloon than a rock!
everything is related to scale. The Earth in small scale acts like jelly or even liquid. And scale affect to time too.
@@Zaqariyah This whole simulation is sped up several hundred times (at least) to keep it short.
For those interested in more details about this effort: This research is a collaborative effort between Ames and Durham University, supported by the Institute for Computational Cosmology's Planetary Giant Impact Research group.

Egg jolts in a plate comes to my mind. This simulation is a work of art and science. It’s fascinating.
I could watch this for hours
This simulation uses smooth particle hydrodynamics; a method where you use particles of a discrete size, temp, mass, etc. You can use it to model a continuous fluid like the earth with far more accuracy than a direct field based simulation would allow.
This uses 100 million particles in total i believe. They showed increasing the resolution (number of particles, so using more particles with lower masses) showed different results, significantly so. We probably need a few billion to model accurately an impact like this, where more particles won’t change much

The whole earth was probably covered in magma at the time, so there wouldn’t be too much of a difference other than a significantly deeper band with some crest lining it’s sides.
It would have been kind of boring because of how slow it would appear if you were far enough away to see the whole thing.
Well the video mentioned that in this sim the moon only took a few hours to form, so considering that time frame while watching it I'd think it'd be moving plenty fast enough to watch it come down. Also i believe he was imagining it as a sim and watching it from within the orbit of moon to earth somewhere. Sounds fun. 😁
Melting lava in the sider space -270 ? 😂😂😂😂😂 u think in terms of human vision
The only hot emanations might come from the sun that simulation is idiotic
It would be quite toasty
It's actually absurd to think about how cataclysmic this event would be to witness. Before impact it's already deformed, and the intense amount if energy makes the solid bodies look like a liquid, really cool.
Edit I just realized they're orange because the material is so heated and after the beginning of solar system that they're essentially just balls of lava
The early solar system was such a crazy and active period. There were probably several more inner orbital bodies that formed that either collided to make the bodies we have now or got eaten by the sun or Jupiter.
Wait no they’re just orange because they’re coloured that way. Thea should really be a cool solid ball and likely the earth should be too… 🤔
@@vice.nor.virtue the leading theory is that this collision happened very early on in Earths formation, so it seems like this depicts fairly accurate conditions for two newly formed bodies. Also even now the Earth is not a solid collection mass, let alone some billions of years ago.

People often forget just how hot the universe was back then, collisions like that, as other commenters have pointed out would quite literally be like two globules of liquid hitting each other in a way. Pretty much everything in the universe was superheated, its beautiful.
The universe forming was Way before the formation of the solar system
It almost looks like some of the debris began to form a small ring system. I wonder if the collision had happened slightly differently whether we would have had more moons, or even rings
The fact that the moon may have formed in less time than it takes for me to finish a day is mind blowing.
I personally finish my day in just six hours, but I appreciate your point of view 👍

Years ago I asked my dad the question "How is there a Moon?" Ever since i loved Theia/Earth collisions and the theory. This simulation is really cool and things like this are the reasons I love space! I'm also happy that this isn't something old but new to me, as this video published 4 days ago, quite recent!

Tell to NASA to take a deep breath and read slowly
Genesis 1:1, 14-19
In the beginning God created the heaven and the earth.
And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years:
And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so.
And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also.
And God set them in the firmament of the heaven to give light upon the earth,
And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good.
And the evening and the morning were the fourth day.

the purpose of science is to question the conclusions. that said; as a layperson, this looks pretty darn conclusive. very very cool. supercomputer data that we can gawk at.
😂
That collision provided Earth with strong iron core and a moon!
Really cool how the proto moon begins to warp towards the proto earth even before impact.
Tides will do a number on planets like Theia when they're that close.
Sometimes it's hard to wrap your mind around that, but when you're dealing with massive objects like a planet and the speeds they're travelling at the moment they collide all sense of what you know and have seen seems redundant.
To see how a planetary body immediately converts that kinetic energy upon impact making the bodies look like jello, is amazing.
@Vladimir poopin i'm not too sure if molten really was the exact consistency of the planetary materials. Solid particles loose from each other, moving en masse will do so like fluid.

Pretty amazing that something this violent can happen to our planet and time later regardless of how long, there is 8 billion of us.
I don't know why but I feel like it'd be really fun to play a sandbox game on a super computer. you could have like 500'000 particles and still be running at more than 360 fps.
It is so amazing to see how magical all this was and how we're here now to be part of it.
It's amazing to think that if the other huge chunk didn't form where it did, at the right mass, with the right momentum, the main bit that became the moon might've just gotten flung away, or pulled back into Earth with it. Gravity would be a bit stronger, but we also wouldn't have the moon's orbit acting like a counterweight to stabilize the Earth's axial wobble. Not only no tides, but true North wouldn't stay pointed at Polaris most of the time, no climate bands or stable coriolis winds, the day and night period would be vastly different... If things even developed anywhere remotely close to the last few hundred million years... There'd still be megastorms everywhere, any life would have to be lucky to have found a safe spot for long enough to survive and thrive out of water, and would either grow to take the weather as it happened, or would never stop migrating and have to rely on sensing weather patterns and basically getting lucky again if it didn't lead them to a place that wouldn't have their favorable range of climate conditions for very long. Forget a seasonal pattern, anywhere, at least in single years. Nothing would have developed anywhere close to what it is now without that thing just happening to get tugged gently into almost the absolute perfect place. It's kinda sad that it's actually slowly getting further away... But I suppose we're also lucky that it's only something like 1 inch every 10-12 years. 😅
Y’all know this is a theory, yeah? They don’t know for sure, or even at all, that this is actually how the moon was formed. It’s a good theory, but let’s not pretend like we know this is how things went down. It’s a cool simulation, and great visuals, and very fascinating to consider the possibilities, but all still just theoretical.
@@ScottGrow117 ...Y'all know how theories work in science and what the difference is from what the word "theory" means elsewhere, yeah?

Perhaps is was on purpose
I would like to see the whole uninterrupted simulation with the time indicated so we know over how long it is. Very interesting!
I agree, considering the Earth's rotation over itself the impression is that everything happened in a few days span.
Well that’s the problem you won’t because it has never been achieved by a computer program, it always fails. They re-ran the simulation thousands of time obviously tweaking the simulation each time and it has never successfully formed a moon.
@@williamrose7184 How does one know this?
maybe they were able to get this simulation to form a moon at the time this simulation was made. But from all the information I have gathered prior to this simulation they have never successfully formed the moon from the colliding of two bodies. It always falls apart and the earth recaptures the initial debris.
@@williamrose7184 Citation needed.
This video could really use a time scale. Given the distanced involved, the description "in just a few hours" really doesn't make sense.
It happened in 13 hours
Cool! Prooves that nothing really collides, atoms just pull each other together!
You can see at 0:35 how the foreign body enlongates as it approaches the proto earth, before impact, what a show must've been to witness
As it gets closer and reaches earth’s roche limit gravity became so immense that it actually elongated the body. If proto earth was massive enough the body would instead break apart before even landing on earth and it would create a ring around the planet depending on its direction.
The tidal forces would have been pretty crazy

It's possible I think in theory for a wormhole to be opened here, then traveled through to a point in space where the light from this collision is just reaching there. Then with a powerful enough telescope maybe it could be observed. Wormhole tech is far, far off if even possible - however I wonder if once our telescopes can see star systems good enough if we could find something like this to observe.
It was man believe me
You go back that far and you would butterfly effect the hell out of us

It's mind blowing to know the atoms in your body today were present during this cataclysm
All of the hydrogen atoms in the water molecules in your body were created in the first 20 minutes after the Big Bang, 13.768bn years ago...
Maybe a very small amount, given how early this is. Certainly not any of the water
@@blueberry1c2 considering there is water literred all over the solar system in placed we thought impossible, it is very widely known and accepted that there are many unknown methods of creating water at the atomic and quantum levels. It possible that the intense forces of this movement created some, but obviously we still lack powerful enough supercomputers to know that. People need to remember all the facets of the scentific method, and stop relying so heavily on small scale lab created analogs and experiments. In the same way the LHC and bigger colliders need to be built to replicate extreme conditions, we would need to replicate and study the proportional extremes of a collision by planet sized bodies to actually "know" anything.
@@kampybballer21 maybe the original poster meant just in the solar system in general and not in this pair of bodies. All of that is molten rock and there's no way water could stay on the earth at that point in time.
@@blueberry1c2 not in liquid form of course, but there are many exotic states of matter. At the atomic scale we are just talking about oxygen and two hydrogen atom, its highly likely it was present then in an exotic yet to be fully explained state of matter. You gotta put QM and GR together equally when talking about stuff on this scale, its a pattern of thinking that MUST not be ignored any longer.

@@michaelpcoffee yeah. I just always wonder what variables actually matter for life.

I agree, the full 10+ hour result would be cool to see as a bonus
Imagine how much energy is released every time the surface of any of those bodies move.
That was awesome. The way the patterns expand as gravity acts on all the particles is truly spectacular
Yes and that aspect, with such high detail in particles and their behaviour, that is how you can see that this is an actual supercomputer produced simulation.
There are a lot of planetary impact simulations on YT, but this is the most perfect and natural one I have seen until now. For this detail level you need extreme computation power.
The entire impact now looks far more like one large swirling wave than just a bang. It's also a lot more similar in shape to colliding galaxy situations for example.
It's a cartoon. You realize that right?
