This feels less like planet formation and more like star formation. Especially when you see this part 18:09 So much volatile motion on the surface AND in the core, so that all it took was a minor collision to make it explode. Reminds me of a star. They're in such a delicate balance.

18:17 i do love how it imploding also makes the asteroids around it implode from the force of all the particles slamming into it

I wish you had checked on that second supernova in the upper left more often to see how they interacted.

omg the explosions are like supernovae! the physics are a little different but once the pressure inside gets too high it explodes and throws enough matter out to restart formation!

18:10 i think what happend here is the shockwave from the impact destabilized the core which was already HIGHLY pressurized causing a small explosion, but the REAL damage was after the implosion

18:12 "I am gonna end this man's whole career"- Blue Planet 18:18"*chuckles* I am in danger"- Purple Planet 18:47-The entire colour spectrum

18:12 that pink planet got atomized 💀

it's crazy how 3d these shapes can look sometimes, especially during collisions. it's like it tricks your brain with the amazing physics to think that it's 3d.

Maybe a biological mod would be cool!(or nuclear fusion or 2 earths colliding)

14:53 Bro that magnetic filed was so good

I love these types of videos based on universe simulations. By far my favorite SST video!

Planet hitting planet 3:02, 3:44, 4:34, 5:27, 5:39, 7:34, 11:50, 12:47, 13:30, 14:20 ( I guess 16:12 ?), 17:56, 18:56, 20:30, 21:17, (the end? 23:34 )

it's like watching raindrops on the window. so relaxing, and a lot happens no matter where you look.

Do you think that if You could spin a planet really fast some material would be thrown into an orbit ? ( for The moon video)

these videos on space toolkit are awesome and remind me of the good ol days watching your powder toy videos! keep up the good work my guy!

Please, please please please please make more of this please please please. This is so amazing.

You can get some pretty silly effects if you set the friction value in the cosmos settings to something slightly lower than -1 (-1.01 for instance). It causes particles to continually speed up as opposed to being slowed down.

Love these vids, keep doing what your doing 👍🏻

this video is incredible. its just such a satisfying thing, watching all the mass coalesce into objects. some orbiting, some colliding. rhe planets growing larger and larger. please do this again

18:13 this part started to make galaxies

Alright i watched it and this really kept me wanting for more really good stuff

I think you could stabilize the particles from exploding by increasing the c power of the particles. or by increasing the timesteps

this game is beautiful as always

this is my favorite game ive seen you play and i wish more people played this on youtube

By the way at 18:18 you can see how the planets melt away from the supernova, i think it is pretty cool. Love this game

Love these new videos of this game. They are so satisfying 🫡

18:12 purple planet be like: waoh whats happening here- (gets vaporized)

fav video so far!

i think turning the max gravitational velocity up caused the max size thing as you turned that up to max( a bit after you separated everything from each other with the spin)

18:09 looks like a sun about to go supernova because it could not hold out against internal force. Of course we didn't see it but it would have been interesting

Do more of Space simulation Toolkit, I love the series!

Another day, another space simulation banger of a video

My theory for what resulted in the event at 18:12 being so violent was how hard strong the pressure was in the core. The core appeared to be trying to escape due to the forces of the shockwaves (explosions) but the shockwaves also forced them together (implosions). Finally, when the shockwaves got disrupted, the "stability" of the highly unstable core was broken and the core was allowed to move outwards, allowing it to rapidly expand and explode. Looks like something similar happened at 18:17

Oh yes this is beautiful

Very cool, just actually got this game!

18:09 super nova!

A black hole formation cuz it formed a accretion disc and a hawking radiation 14:31

The explosions are a byproduct of having such a high maximum collision speed, if you set that lower, there will be no more explosions, at the cost of having a lower "speed of light"

18:18 you can see a purple planet get destroyed by the explosion

Suggestion: Try this again but with dirt stone iron and other stuff also you should also try the making 2 equil sizes and make them collide

I watched 2 OF YOUR VIDEOS and bought the game

This game is absolutely incredible.

11:52 It shattered its moon counterpart which is kind of neat 15:08 that other planet from it was created from initial impact remnants

this is my third time watching, this is so far my favorite vid of yours.

This looks super cool. My assumption for the behavior of the 'planets' would be that, based on the view that we had there's a sort of reverberation in the body when a collision occurs (I think it acts as some sort of momentum multiplier for particles), and I am guessing that interaction with the "damping" mechanic (maybe you have damping turned down?) in the sim causes there to be a point where the 'planet' as you said is no longer stable... I am obviously no scientist but this had me thinking/wondering. I am interested on other's thoughts.

At about 14:30, the first star of the sim formed and it has matured at around 18:00. It's mainly powered by quantum tunneling instead of conventional nuclear fusion because of the sim

if only i had the full version the galaxy looks great at the formation of the universe

man this simulation was so satisfying lol

ANOTHER VIDEO ANOTHER VIDEO ANOTHER VIDEO 🔥🔥🔥🔥🔥🔥🔥

This was very interesting I want to see more of this lol

I'd love to see this again but without zooming in or out (we can see any collision happen and we can make points that show when something interesting happens)

Spike can you do a breakdown of your settings for this video?

Do this but on a bigger scale if possible, because it's really fun to watch.

keep making more videos of this game please

More big bang i subbed im your fan

Mesmerizing.

pls more of this

This game is amazing.

16:05 was basically a supernova

Spike just goes insane after blue collides

the formation of the universe had matter EVERYWHERE, so not only would you need a ludicrous amount of matter, you would also need to have a giant room to do stuff in

This is so cool I mean who will unlike this

This but with elementary particles. Basically a nuclear physics simulator. That'd be super fucking cool to see.

18:14 Basically how every large empire or kingdom turns into modern countries

Btw, to make it more realistic to the Big Crunch, increase the gravity of materials

This made me get the game

at 5:50 you can see some small objects pass the roche limit and fall apart

so I actualy think that if one of the smaller particles hits the bigger one it's gong to make a fission reaction but if 2 particles (small or large) combine together without exploding they are going to make a fusion reaction

18:17 that purple planet got destroyed by the explosion

would watch an hour long vid of this

13:33 i think it didn’t explode since it was pointing like a knife and not a hammer so the pressure wasn’t as hard and it just got wedged and reformed

4:59 boom yes

bro its crazy thinking some of the smallest planets where once those massive planets. all was calm until that happened

I think that the collision of blue and yellow it made a prodoplant that made purple

14.28 that is a kilonova similaar to supernova but is made by colision of two neutron stars

Approved

Amazing game

6:54 this collision basically happened when the moon formed, but slightly different

Huh well lets see how this goes

I imagine you can let this run and create a solar system with some starting spin ofc

Spike Viper: i can't read that.

If you spin the core of a excited planet it can get a bit bigger

I lost count of how many supernova-like explosions have occured

make a soler system then explode it

18:14 The purple planet just got obliterated by the particles lmao

Big boom

Btw if you still have gravity as a cubic function, just know that a quadratic function is the ONLY FUNCTION that can support stable orbits if you want things like moons

18:17 pruple planet got shredded

When they reach a certain mass they become stars!

Big Bang.

14:26 : The blue and yellow planets was start,when collison happens,the supermova will come

please play SpaceSim. it uses the OpenSPH engine to make an entirely particle based cosmological sandbox, like sst combined with US

TODAYS EDUCATIONAL OPPORTUNITY: Centripetal VS centrifugal forces

goddamn this looks sick

bro do this again but add like a small amount of energy and creatures and see if they survive inside of planets that form

Cool

Those explosions are supernovae

*@Spike Viper* I think 18:10 is caused by your change at: 3:59 Please try this simulation again, but at less extreme settings (at least near the end) (I would also like to see a universe be started by the most *EXTREME!!!!* fusion explosion you can create, to cause the initial rip apart of the starting material, instead of rotation) (preferably do a "training video" first, on how to cause the most extreme explosions)

11:52 i like how the asteroid gets obliterated by the debris from the explosion 14:52 i think it's a gamma ray burst ?

The thumbnail spike looks like he’s crazy
