Hey! Thanks for checking it out, I'm glad you like it :-)

Thanks :-)

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.

Thank you!

Sorry :-( The colors are to make things more clear

ye

yes

Mostly default I think, not sure

Thanks! :-D

@@physics_hacker :)

Thank you! :-D

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

Thanks! 😃

?

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 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.

Breakup by tidal forces yes

Hello! :-)

@@physics_hacker :D

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

Are you asking for that as a future video or?

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

I guess, kinda 🤷

?

it's SpaceSim, not a game though

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.

It might be, I don't know 🤷

Is not how the cartwheel Galaxy formed

huh?

@@Sun1337-n1l Oh, I see

?

Yep! After enough orbits it should start to fall apart because of that, just like real satellite galaxies.

A Galaxy orbiting inside of IC 1101

@@moosine9 ?

Well yeah I​C​ 1101​ might be so big that other galaxies can orbit inside it do you know through.​ IC 1101 history is collide with other galaxies!

a what now

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

War games?

Yea, not sure why it did that

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.

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

Thank you! I'm glad you enjoy it! :-)

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

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.
