Planetary collision simulations - from an asteroid to a Mars-sized planet
HTML-код
- Опубликовано: 6 июн 2024
- A set of collision simulations with gradually increasing impactor size.
Other parameters are the same for all simulations, namely:
- Impact angle 45°
- Initial impact speed 10 km/s
- Target is a differentiated Earth, with core (density 7860 kg/m^3) and mantle (density 3050 kg/m^3).
Earth contains 2 million particles, number of particles in the impactor varies depending on its size.
Computed with OpenSPH

this would probably affect the global temperature
this would probably affect the trout population
this might also create a slight ozone hole in the atmosphere
Can we get a new joke
@@typicwhisper6569 There was no joke
-Serious Oogway
And the stock market
This would be very bad for the stock market 🥺🥺
Oh shit, the economy!

what
It’s always nice to see a simulation as opposed to an animator’s impression. What animators don’t get when they animate planetary collisions is that on large scales, solids behave like liquids.
Fr!
And also planets partially/mostly _are_ liquid, even when they’re not being liquified by collisions
He is not a animator.
@@SandoMalv he didn’t say he was
Reread their comment
@@SandoMalv they weren’t talking about the person in the video, they were talking abt in GENERAL
Man, I think that last one would be catastrophic for the economy.
Actually it’d be great! Inflation, poverty, rent and unemployment would be at an all-time low
@@badpiggies988yeah but sadly school will still be open 😢
@@liamurr. But quiet kid incidents in the only country where such things regularly happen (which I live in myself, for the US nationalists rushing to comment “ungrateful” based on my pfp) would also be at a record low
Wow! I absolutely love these high resolution impact simulations. Shows just how precarious our existence really is… I am now a new subscriber 😊
1 year and still no reply 😊
1:45 This might make mexico slightly hotter.
wow! beautiful but frightening. very impressive presentation.
I loved the 3000km one, that one was the coolest
He sacrificed his PC for this
school would still be open ):
@@abxyabxy281the math teacher would destroy the planet or meteor or moon for school to be open
It's a good thing we don't live on a planet.
we do, its just you people who think we dont are making too many excuses and fake reasons on why we aren’t
@@ProGamer_69420 its a joke
ehem the space are not real we are just actually in a globe that was made by goverment🤓☝
That one idiot be like;
dont let the joke fly over your head
There’s something very disconcerting about seeing the crust of a planet literally ripple.
all of these are satisfying in a way
This will have negative consequences on the trout economy
We probably need atleast 2 air conditioners to fix this
How realistic is the skidding & bouncing of the fragments on the surface of the oceans? Fantastic perspective 👏
Not at all, this simulator was made for large collisions between several planets, not planets and asteroids
That part is not realistic, the reason that happens is because the particle size is too large to accurately simulate how those little fragments impacting would look like.
To get realistic collisions with oceans you would probably have to increase the particle depth and add a 1.01 g/cm^3 layer to the planets.
@@petersmythe6462????
what a beautiful way to go
This may affect the number of moons in our planetary system
I will gladly give up my guns if it means we can avoid a planetary collision.
I think this would affect the human population, what do you guys think?
It would affect salmon runs
id survive
@@phantomsrage6523 Yeah, maybe if you hid in the closet maybe you'd survive. Just guessing
so you're telling me that getting a second air conditioner won't really do anything
Gorgeous
Look, 1500 km was game over earth. I kinda feel that 3000km was the encore to end all encores.
this will dramatically effect fishing season
this is an interesting place for procrastination to bring me
for reference, no living thing has likely seen an impactor larger than 300km, and nothing over 200km is confirmed
The 3000KM impact has a 85% of causing a 1-2 magnitude earthquake
💀
This would ruin fishing season for well, just everyone!
you made that view of the 3000 km one feel so gigantic and claustrophobic at the same time what
can't wait
@The Govrnment of The Romogov [I.A.B.A] wassup bro
Could you please make a SPH tutorial
Please do how inner rings of saturn were made for my research abot saturns rings
Squirrels in Kansas must be having a rough time after this one.
I just scrolled to comments before the first asteroid made collision, we are safe.
Random Oblivion Guard: It was just the wind
So I got the SpaceSim software but I can't figure out how to record.
I tried the inapp tutorial but it doesn't show anything. It just claims I have to press the "record" option, but I can't find it anywhere
You have to click and hold the "start" button. If you hold it, it will show another option, a play button with a red circle. When you select it, it will record a video while the simulation is running.
@@pavelsevecek Hey thanks
Somehow I didn't see it 👍
@@Danger_N00dle yeah it's quite hidden, I should put it somewhere else.
This would probably effect the speed of Wi-Fi
I still cannot figure out how to have textures added/shown on simulations/renders, can someone help me with that?
You have to enable textures under "Project -> Shared properties -> Enable textures", then set the path to your image file in the body node (look up "Texture path" under Visualization category), and use the state files (.ssf) as the output file format. Then the textures should appear.
@@pavelsevecek Thank you! :)
I hope this didn’t affect the bear population
Think the global economy would struggle a bit.
Schools would still be open after this.
100km, 250km: pretty sure it would do more than that to the global climate and ecosystem once you take thermal effects into account, but the planet itself isn't going to be disrupted.
800km: That's gonna make some new plates or something.
1500km: Well, looks like Theia's got a new roommate now. And they trashed the place as soon as they moved in.
3000km: Now you're basically doing late-stage planet formation all over again.
what computer your using
In no case does the asteroid fall at a 90° angle, but it spins around at least until it enters the atmosphere😂
I imagine 100 km would be enough to sterilize every square inch of the planet. Everything above that is overkill.
Pavel 😊
I think these would probably drive energy prices up.
Pretty much anything bigger than 800km is the end of life. Even if not directly hit the rest of the planet will experience devastating earthquakes and tsunami. Very good simulations btw.
The dinsaurs were hit by an 80km asteroid and 75% of earth just died in 24 hours
*30km
@@cmdrgarbage1895 Not true either, the asteroid wasn't even above 10 kilometers in size.
@@g-ray4088 You're right, I guess I was stoned while typing
how do I use SPH? it's kind of confusing and it's obscure so I can't find any tutorials
Try SpaceSim, it's much easier to use. It can be downloaded from the same page as OpenSPH.
@@pavelsevecek okay
Hustý :D
Largest sim I have even done was a million particles.
YET YOU DO TWO MILLION REPEATEDLY. GIVE GOOGLE BACK THEIR COMPUTER!!
Scary
how do i get it to look more fluid with raymarcher?
you hit the play button
Where’s the respawn point for 3000km asteroid?
In the 500km one India go hit by a 12938 magnitude earthquake
All of these asteroids would be the end of all life.
1:44 What would you do in this situation
personally i would step in
IDK, it looks like it would affect salmon populations
I would intervene and say ''STOP THERE! THAT'S NOT COOL!'' it always works
Earth turned into a star at end 🎉🎉🎉🎉
👍
They should simulate shockwaves aswell
You can see seismic waves in the larger collisions, but they'd need to simulate the atmosphere and the oceans for more accuracy
We really are just a bowl of hot soup floating around space.
First one is basically the Jurassic mass extinction event
This would probably affect the local trout population. Also the population of microscopic specks
we will be fine
good but lol our planet its not jello
At high pressures, everything is jello.
how are u able to have so many particales
The simulations take time, hours or even days.
@@pavelsevecek oohh
“1500” That’s the same size of the Moon.
1:26 the space Trash be like
30000 kilometers could’ve form a minor moon
0:41 anyone else notice the P-wave travel through the earth here
i noticed after you pointed out the wave rippled on the planet
This doesn't seem like it takes Earth's atmosphere into account.
Even for the smallest asteroid here, the atmosphere wouldn’t make a lick of difference.
The one that supposedly killed the dinosaurs was 10km across, and the largest to ever hit earth that we know of (minus the small planet that made the moon) was at most 15km across.
A 100km asteroid would be global extinction.
big splash 2: electric Boogaloo
schools will remain open 💀💀
I am pretty sure that even the smallest one of these impacts would be enough to wipe out all life on the Earth
The asteroid that killed the dinosaurs were 10-15 kilometers wide. So that's unlikely.
definitely would
I think earth at the end turned in to a sun

This wouldve affect the price of corn
is this space sim
It's OpenSPH.
Universe Sandbox 3:
This would affect the ocean temperatures
There won't be long now and its à good thing
water behavior
it looks like a fluid
No worries, I'm sure the economy will recover.
Poor old Earth
Not the stock market!!
Nice. Planets are balls of liquid... only a hard crust on the surface, which humans walk around on thinking it's totally solid.
IMO we could easily "survive" the calamity of the smallest impact. There would have to be major re-structing of the world's nations and practices, United Nations coordination, and eliminating military activity and such. Massive tsunamis and high-speed winds, and probably earthquakes would be the short-term problem. Just getting people informed about what just happened would be difficult! Since everyone in the neighborhood would have been killed. You can see the devastation in 3hrs. We would want to shut down dangerous human activity e.g. nuclear power plants... and then dealing with material & dust in the atmosphere would be tough... and then over the longer term, the effect of the original impact site would be glowing with the heat for several thousand years and create havoc with the world's weather patterns. Unless we execute everything perfectly, humanity could be ultimately knocked back to the stone age again, with zero modern civilisation and surviving in small groups at first, but don't worry, we developed everything we've got right now in 5,000 years, so we'd be back after that time again - assuming we were able to adapt to changes in the climate and weather.
After your second (250km) impact, IMO there would be no lasting human survivors. Shockwaves would appear tiny in your 720p video but they would affecting the actual spherical nature of the planet, and the effect to humans would be sudden multi-hundred mph winds, super-high tsunamis, earthquakes and temperature changes (as the altitude changes), all within one day. It would be extremely difficult for any humans to survive that, and those that did survive would be in a hostile world with great difficulty finding and growing food & shelter. Your simulation does not show clouds & water, but the effects would be more obvious then.
500km impact and above - would simply wipe everyone out within the first day IMO due to massive tsunamis, earthquakes and high speed winds transporting and atmosphere and everyone in it sideways for several hundred miles in just a few seconds 😀 I would not want to be on the International Space Station when the big one hits!
The first one alone would literally destroy us. The dinosaurs were taken out with 10-15km. The first asteroid in this simulation is 100km - a good 6-10 times that. We'd be cooked by a monster heat-wave, followed by a nuclear winter that would last untold decades.
100km to 3000km
“Schools will remain open”
I did this 7 months ago where are my likes
This would affect the ocean’s temperature😕
*Earth and theia be like:*
bro removed britain
That sliding seems unnatural.
It is, it's a limitation based on the way the particles work I believe.
minor inconvenience
Completely inaccurate but looks good
wdym completley innacurate. the only innacurate thing is the oceans still exist and the atmosphere does nothing(it wouldn't do anything in the situation but the software doesn't care abt the atmosphere)
This will not affect the trout population
Nah id survive
is that game on the Apple store
no
