Vložit
- čas přidán 25. 06. 2022
- Several SPH simulations for various sizes of the target object. The target has 500k particles in all simulations, the number of particles in the impactor varies, depending on its size.
Parameters of the simulations:
1. target 3cm, impactor 0.35cm, angle 30°, speed 3.5km/s, simulation time 4ms
2. target 100m, impactor 10m, angle 30°, speed 5km/s, simulation time 1min 12s
3. target 10km, impactor 1km, angle 30°, speed 5km/s, simulation time 1h 40min
4. target 1000km, impactor 500km, angle 30°, speed 5km/s, simulation time 20h 40min
5. target 69911km, impactor 58232km, angle 15°, speed 30km/s, simulation time 16h 18min
Computed with OpenSPH

That Saturn vs Jupiter was probably the most VIOLENT looking explosion I've ever seen.
I wonder how bright this impact would be compared to the Sun.

A star... is born lol
1x sun
@@MrUnclehouse
That moment when Jupiter says his line for the last time "its orbit time" and saved the earth impacting with Saturn was just a love letter to the 7th art itself. I cant imagine a more touching scene than that in history.
ok Raul Aguilar Gómez
Truly a gorgeous moment
certainly one of the moments of all time
It's morbin' time
Then started orbiting all over the place 🤯🤯😎😭
Imagine that for all the ludicrous amount of energy these collisions would release, they'd still be little more than firecrackers compared to supernovas or collisions between black holes or neutron stars. The scale of energy release in cosmic events is simply mind-boggling.
Right??? i always think this. but then supernovas weren’t even a pebble compared to the sheer force of the big bang.
The energy that last thousand light years
@@lixue_izarit wasn't an explosion
@@petterlarsson7257 It was rapid expansion that caused a huge flow of energy & heat which literally created atoms. Im pretty sure that could be classified as an explosion, it’s definitely more than anything we’ve seen on Earth that we’ve considered an explosion, that’s for sure lol.
If these are firecrackers then a super nova would be a hydrogen bomb
1:40 The smiling sphere
🌚🌚
Looks like he’s monching
what were the initial velocities and angles?
I added the parameters to the video description.
@@pavelsevecek🎉
1:30 The planet basically became inside-out
Good point
I should stop missing out on these amazing simulations
hi the battle bricks guy from boblox
Very nice. But I'm a bit confused/surprised that a 3cm impactor can possibly make any different at all to Jupiter!
Highly unlikely...
It's not a rocky planet also. Not a good example of impact on a GAS giant.
Check the desc.
These collisions are at light speed so a 3cm object colliding with Jupiter would release a cataclysmic amount of energy.
Idk I think 3cm is pretty big.
The Jupiter and Saturn collision was the most destructive thing I’ve seen today
I really wanna see 2 planets colliding with each other, would be such an interesting sight to see, especially because its something so astronomically big but still within the timespan of a few hours which a human can easily sit and observe
theres an asteroid belt between earth and mars ...duhhhhhh
@@johnnyllooddte3415 It's between Mars and jupiter....
@@johnnyllooddte3415So what? Asteroid impacts and planetary collisions are different
that jupiter turned to the biggest sun while the saturn vs jupiter almost ended
Is that just the heat of collision shown in the Jupiter model? More so, does this sort of impact briefly ignite any fusion reactions that add to the heat of the final body?
Cheers,
It's the heat from the collision + the internal heat of Jupiter's mantle. Nuclear reactions are not simulated here.
@@pavelsevecek thanks mate. Love your work and cheers for the reply?
@@aSpyIntheHausyou sound like a aussie
We probably need atleast 2 air conditioners for this
I case of Jupiter, there might be thermonuclear reaction have started. Did you calculate this?
No, the code does not calculate nuclear reactions.
What are you making this with? Looks awesome
Check the video description.
Awesome but incredible inaccurate, i mean a 3cm object even at speed 99.999% the speed of light can do nothing important to Jupiter or even our moon
@@pavelsevecek what's the name of the simulation program I see the parameters was wondering if it's an actual program or if your just using an engine and doing it yourself? Is sph simulations a program or your own thing I guess is what I'm asking
@@thantsag5830 Obviously, the 3cm object collides with a 0.35cm object, not Jupiter.
@@OGdirty1Kanobi The program is called OpenSPH, there is a link in the video description.
Interestingly, . . . . this is the piano music that would be playing if this event actually happened.
Simulation time is the time inside the simulation or the time it took your hardware to simulate it?
It's the time inside the simulation.
Saturn went in style, bombing Jup with the ring, then killing itself in it.
And here I thought it just went ‘Bonk’.
How do I get SpaceSim in phone mobile?
2:00 gravity on the direct line of attraction is impossible, this is a global misconception. gravity is possible only on repulsion. the planets will not stretch towards each other. they will shrink. it is impossible to push them together, a moment will appear to the side and it will begin to rotate together. there are a lot of such objects in space - paired stars.
I know a 0 degree impact angle is impossile but it's just a simulation and it dosen't matter that much i mean at least it looks good
Can you make it but at a much slower speed? I would like to see if this type of collision can create a Worthington jet.
It would be interesting if this could create new satellites.
It would be nice: impact on mars or venus + earth consequences.
Everyone thinks about direct consequences, but about indirect?
cm is centimeter in this instance?
epic
much better than universe sandbox
Wow. *puts 3D movie glasses on*
from where did you get these calculations?
See video description
game name? or just a simulation or animation?
Tiamat.. the remains of the asteroid belt.
this new universe sandbox³ prototype looks amazing!
lol we wish
This is brutal simulation 😅
How long does it take on average to run the simulation?
Usually a few hours.
this will likely drastically affect the mosquito population
Good.
I wonder when computers will be fast enough to run this in less then an hour
or even seconds
did i just see a planet get folded inside out
what does sph stand for
Smoothed particle hydrodynamics
Holy crap. Why stop there? Keep smashing planets and asteroids and comets and stars into one another!
There wouldn’t be any explosion until they both reached each others cores but ya
What es that game?
Did the one at the end end up becoming a star?
@Aero / Aron 2 [U.P.A 2] *n u c l e a r f u s i o n*
No. You'd need to collide about 80 more Jupiter sized planets I believe. It's just molten material/rock vapor that's heated up to thousands of degrees.
@@TactileCoder ah, I thought Jupiter was close enough to being a brown dwarf that a good bit more mass plus heat would set off nuclear fusion
@@thehoodiewitharudy9020 It's "close" in terms of physical size: gravitational compression means Jupiter actually would shrink in diameter with more mass. (Some brown dwarfs could fit inside Jupiter!) But in terms of mass, the smallest deuterium fusors are ~12-13 times more massive, and the smallest stars are ~75-80 times more massive than Jupiter.
I’m a little confused - what is striking what?
See video description
Nice!
This seems to be wrong in simulation. Shouldn't Jupiter get deformed as well as Saturn before collision? The gravitation of both should tear apart both.
jupiter is more dense then saturn so it gets deformed a lot less then saturn but it still is getting deformed a little it's just hard to see
this is sick! but how do you make it 3d? (also for spacesim i think you should make the planets heat eventually go down so you can see what the planets look like afterwards)
0:30 slow the video down to 0.25x speed to approximately get real time
Does the last one take into account that Jupiter is a gas giant?
Are you developing for a game? Because this looks completely Awesome. 100/1
this isnt a game its a simulation (that takes a lot of time probably days to render), check the description if you want the software he is using
@@zahrannahyan9666 i have the software and I know what you mean. Im talking about if he’s developing the SPH for Universe Sandbox, because it looks like he is + Universe Sandbox is adding SPH
I don’t think universe sandbox is adding SPH except maybe for like a fun one off project. Unless we all get quantum computers.
@@GodofWeird They actually mentioned that they were looking in that direction, but were leaning away from sph and towards other methods.
Me who needs it:
I NEED ITTTT
What’s the app called?
OpenSPH, see the video description.
the better universe sandbox
Really thought they were forming a new planet 😂
Can't tell if this is accurate as there is missing info. A 3 CM object would/could not destroy an entire planet as depicted at the velocity depicted. It would have to be going at about 90% the speed of light, or the planet would have to be quite small. We need to know the speed of the objects and the size of the target planet.
The first simulation is a 0.35 cm object colliding with a 3 cm object, not a 3 cm object colliding with a planet.
@@kasimir1359 What is the speed of the smaller object in each collision? And what are the sizes of the bigger objects in the other collisions? Thank you in advance.
@@friartux6946 All of the sizes and speeds are in the description.
Is it just me?, Or every impact between 2 large objects always creates perfect conditions for moons to form?
yes, because a lot of debris is ejected which makes it possible for gravity to arrange it into a new object.
It just formed a new star
No it didn’t, a star has to be at least 80 Jupiters in mass to be a star. The reason why it looked like a star is because it was so hot
What are they colliding with?
Like the 3cm object, what does it collide with?
The sizes refer to the targets. Impactor sizes are in the video description.
They collided to what
I would like to know too,
How small is that planet?
The sizes are in the video description.
where is 3 cm?
2:13 what happened to the gravity?
the gravity is still there its just more spread out because it was a FUCKING EXPLOSION XD
THE FIRST ONE IS YUMMY YOGERT
The Saturn and Jupiter impact would probably create a really small brown dwarf that burns for an extremely short time.
May we never know.
Good job you have two stars in the solar system it’s now the end of the world
seems like Jupiter and Saturn are being treated as solid tho…….nice sim nonetheless
I'm trying to understand how this works, so i had to add save to file node ater sph fragmentation then use it to render?
Not a save file node, that only saves the final state of the simulation. You have to set the output in the SPH fragmentation node. Then the simulation will generate a sequence of files you can use for rendering.
You can ask on Discord if you have any more questions.
@@pavelsevecek ohh, i see that now, which file to choose, data file, state file, text file, vtk file, pkdgrav input or vdb file?
@@avatarxs9377 Data file
How long does it take to render these simulations?
3bi years or real time?
The last one tho 🔥
This is most unlikely.... Sone years ago fragments of a comet crushed into Jupiter....we can still see the marks they left.... But nothing really relevant happened to the planet as a whole....
You realize how small comets actually are? Compared to fucking Saturn?
Please more please about cosmos and astronomy. Like all about space. All subscriptions about Space. May relax music also
1:51 new planet
The 3cm object exploded. 0:21
But I thought Jupiter is a gas giant. Why would any type of object affect it in that way unless Jupiter is not a gas giant.
Relative to what ???????
3 cm and that amount of destruction?? What is the density of the object and at what speed? The object(s) that crashed on Jupter in 1993/1994 were bigger and the impact way smaller.🤷
Ok, I didn't read the description box. My bad! 😅
Ez már kezdettől egy elhibázott szimuláció. A Shoemaker-Levi üstökös már csak elég nagyocska lehetett, de távolról sem csinált ekkora ramazurit amikor beesett a Jupiterbe!
1:49 it looks like an planet again...
ur telling me dropping my pen can blow the earth omfg
1:43 has a smile
WHAT THE FUCK IS A KILOMETER!?!?!? *Insert american hawk noise*
imagine having to pay the electricity bill for every rendering
Сразу вспомнил фильм Армагеддон с Брюсом Уиллисом. Это жесть, если такая махина врежется в Землю.
how the heck do you make it so objects under 100 meters dont crash the program?
Bro what did jupiter do to you
It make you stupider?
0:59
That happened to me once
Are you ok?
1:25 how it feels to stub your toe
Wow I never expected those situations
ahaha the earth is hit every day by 3cm pieces and bigger and we have yet to do that ahahahaha
*water noises*
Jesus christ almighty why are they hitting them so fast
How do i use thoose graphics? because when i enter the game is just bad graphics.
Saturn-piter
2:37 moon is formed
its will became an star?
Something needs at least 80 Jupiters in mass to become a star
@@coconutbird8093 oh
Spongebob movie Irl be like
