I post stuff related to space and games (and both, space games!), music, and make playlists on many subjects.
Moon-forming Rocky Ring Around Earth ( With 7 Minerals! ) | SpaceSim
A ring of 250k particles made of different minerals collapses into moons which collide and interact with each other, eventually only leaving a few moons left.
This is not my first attempt at a moon-forming / circumplanetary disk. It is the second major project of this type for me, I'm doing much more with the first project and hence I am still working on it, while this one I feel comfortable posting as-is. Check my community post that I put up around the release time of this video for more info on the first project. One major difference is the materials, this project has more materials, although the older one included water while this one does not.
Each mineral is represented by a different color. The different minerals have different densities, so denser ones tend to sink toward the center of the moons that form, this is why although the minerals are represented by vastly different colors, the majority of them are denser and thus locked up inside the moons, resulting in the overall yellowish color of the moons' exteriors, owing to a majority presence of basalt (yellow) on the surface, with less common but similar colors green and cyan (representing quartz and enstatite respectively) also often being on the surface, giving the yellowish color a greensish tint as well. I've included below a table of which colors represent each mineral and the densities they got in the simulation, getting the densities right is tricky so while I've tried to give them close to real life densities, they are not perfect. In the table I also include how much mass each material got, the mass numbers are very arbitrary since I wasn't such how much of each there should realistically be. If you know of resources on this subject please let me know. After the setup of this sim I did find that the ratio of iron to nickel should have 5-7% nickel, so I can use the going forward, but I'm not sure what the others should be.
Minerals table, ordered by density:
Mineral | Color | Density | Total Mass
Quartz | Green | 2.65251 g/cm^3 | 0.0005 M_Earth
Basalt | Yellow | 2.95857 g/cm^3 | 0.005 M_Earth
Enstatite | Cyan | 3.23886 g/cm^3 | 0.002 M_Earth
Olivine | Pink | 3.77072 g/cm^3 | 0.005 M_Earth
Perovskite | Dark Green | 3.91465 g/cm^3 | 0.005 M_Earth
Iron | Blue | 7.84927 g/cm^3 | 0.001 M_Earth
Nickel | Purple | 8.91343 g/cm^3 | 0.0005 M_Earth
The time elapsed in-simulation during this video is 14 days, 13 hours, 18 minutes. 250k particles were used, and by the end of the simulation there were 32766 bodies left, most particles had become incorporated into the moons.

Cube Becoming Black Hole Accretion Disk | SpaceSim
Переглядів 26621 день тому
A cube of particles orbits a supermassive black hole (modeled after Sgr A*). The cube is torn apart by tidal forces and forms a disk orbiting the black hole. The colors come from the temperature of the particles. This simulation of 30,000 particles ran with the IISPH solver. Let me know if you'd like to see a version with more particles or a longer/slower recording.

This is a simulation of Achernar, the brightest example of a Be-type star in our sky. Be type stars are rapidly spinning B-type stars which can form a disk around themselves due to their rapid rotation, as showcased in this simulation. The colors correspond to temperatures, roughly equating to their blackbody temperature's color. Reds are cool, blues are hot, dark blue is the hottest temperatur...
Two Galaxies Orbit And Merge | SpaceSim
Переглядів 2,8 тис.3 місяці тому
In this simulation, a smaller galaxy orbits a larger galaxy in such a way that it orbits a bit around the larger galaxy, disrupting it, and the small galaxy then merges into the larger galaxy. This forms large tails extending out from the galaxies. This scenario is mainly a what-if, as this configuration is unlikely at best. 250k particles.

Awesome!! I saw this through the r/Starset discord server and im impressed at how you made this
Hey! Thanks for checking it out, I'm glad you like it :-)
10/10
Thanks :-)
How did you do this? Is this your sim that you made? Edit: Sorry, couldn't read the title, SpaceSim. I'm currently making my own physics sim so I wanted to ask how you managed to get the line patterns to emerge as the galaxy spun. My sim is not emergent like that.
Yeah, it's just changing the colors of a regular galaxy in SpaceSim. It's really cool that you're developing your own physics sim. If you release it at some point lmk, I'd love to test it! As for the line patterns, they should emerge naturally as a consequence of gravitational attraction. Because the particles aren't placed perfectly, slight over-densities should collapse under gravity, which as the particles move in a circular motion in their orbits, form those linear/spiral shapes. Not sure why that wouldn't be happening in your sim. What does happen in yours?
@physics_hacker well, I haven't yet implemented the barnes-hut optimization so my number of particles is limited to around 1k, thus they can't really be pulled into a pattern like that.
@@theuntitledgoose4193 Ah, I see.
Holy-#
Nice work!!
Thank you!
It's giving me a seizure from the colors
Sorry :-( The colors are to make things more clear

1 hour and 30 minutes long??
yes
what settings did you use for the molecular cloud? or is it the default
Mostly default I think, not sure
Lovely. Now do a binary nova, where one of a binary pair of stars goes nova. Then see how gravity effects the debris...
10/10
Thanks! :-D
@@physics_hacker :)
amazing! :D
Thank you! :-D
how did you do that?
I believe a mixture of supernova feature and putting a dense object in the center that would make it explode anyway. The range of conditions where it does this though is pretty narrow
10/10 good simulation:)) +100000 aura
Liked it👍
Thanks! 😃

Simulator name?
SpaceSim, but it's easier to find by looking for OpenSPH, a similar simulator created by the same dev. Here's a link: pavelsevecek.github.io/
@@physics_hacker Ty! Gonna use the link rn

What?
I guess spaghettification is not only with a BH, even Jupiter’s gravity spaghettified Comet Shoemaker-Levy 9.
I suppose. Spaghettification is really just an extreme result of tidal forces, which this also is also a result of, but to a less extreme degree. It's still resulting in the breakup of the smaller object but in this case the smaller object forms a disk, which isn't really a feature of spaghettification by definition.
That was because the sun’s gravity spaghettified the most stormy planet.
Breakup by tidal forces yes
hi there
Hello! :-)
@@physics_hacker :D
how make this
To be honest I'm not sure this is reproducible these days, I think the way stellar wind works has been changed since I made this video so it may not work anymore. There is a preset in the software that does something similar though, the preset is called "Igniting Stars"
@@physics_hacker aw
Sun tore up by a black hole.
Are you asking for that as a future video or?
What would that look like from earth. Please give a simulation from here
I mean realistically Earth would be long gone. Collided into something or, more likely, ejected out of the solar system. Even assuming that it's fine though, it wouldn't look nearly as interesting since all the action would be on roughly the same plane as Earth's orbit, so it would mostly just look like a line across the sun. Thanks for the suggestion though, I appreciate it
Looks like a Galaxy
I guess, kinda 🤷
😮😢😢😢😢😢
?
What’s the game name
it's SpaceSim, not a game though
How do I find this game?
pavelsevecek.github.io/
If this happened, earth is doomed
would probably be long gone, this would require a lot of reshuffling of things since Jupiter would have to move all the way through the inner system.
I thought this is how the cartwheel Galaxy formed😂
It might be, I don't know 🤷
Is not how the cartwheel Galaxy formed

Is this real what galaxies are these.
This is a simulation, mostly a what-if. Realistically finding something like this would be very unlikely. Perhaps something similar may exist though.

1:38 😮
Yea, not sure why it did that
how do you make it so high quality? you did 250k particles, i did 500k, mine looks like it has less particles than yours, how do u do it?
Most of the work with this one was in the color palette, i didn't really do much out of the ordinary otherwise, my exposure/compression/bloom settings that I usually set up also tend to help, good contrast but not too much really exposes the structures the particles form which can make it look like more particles.
now i wish that the sun really had a ring system it would be so cool!
It does! Several actually, depending on how you look at it. The asteroid belt, the Kuiper belt, Jupiter's trojans, etc
@@physics_hacker cool but i meant like rings like Saturn or something like that
@@mikeskadi 🤷 There's really no difference.
@@physics_hacker bruh
@@mikeskadi what
👍🏻👍🏻
This is beautiful - thank you for posting such an interesting simulation!
Thank you! I'm glad you enjoy it! :-)
These kinda videos always end like 10 minutes too early
yea, I wish I could make them longer but millions of particles take days to simulate any decent length of time, days where I basically can't use my PC. I have a laptop I can use during that time but most of the stuff I do on my PC my laptop can't or isn't set up to. And that's when it goes well, I think this video stops where it does because the program crashed, I have another version posted with less particles but runs longer
What a bad CGI , useless 🤮🤮
Why is it bad? What can I do to improve it?
@@physics_hacker dont use fluid dynamics...
@@MarcusFreeman-n7p ...It already didn't use fluid dynamics. This is a n-body gravity simulation. With that said, how would avoiding fluid dynamics be worse? It would certainly be more accurate, if fo no other reason than to be able to include things like the effects of magnetic fields.This software can't really do either currently but it would be nice, and more accurate.
Wow
