SST - protoplanetary disk (kind of)

In the last update (which is huge by the way) actual gravitational interactions between particles were added. The possibilities of this game have expanded infinitely... again. This is a 12x timelapse of

some cool flying balls

timestamps:
0:00 - start of the simulation
0:20 - the planets now have distinct boundaries
0:50 - the main ring starts to collapse
1:20 - first collision (a pretty boring one)
1:31 - a series of collisions including one planet crashing into the core
1:40 - some protoplanetary activity

there's a lot of cool stuff happening between these timestamps

3:10 - the last collision. Only accretion will happen after this point

0:00 The Star Forms
0:01 The Star Starts Pulling Stuff Towards It
0:03 Stuff Gets Pushed Away
0:06 A Belt Forms
0:09 Planets Form Whit Rings Around Them
0:14 I Loses Its Ring
0:16 H Loses Its Ring
0:20 the planets now have distinct boundaries

0:26 D Loses Its Ring
0:50 E Loses Its Ring
0:54 E and D start orbiting each other (yipee binary planet)
1:00 every minute ill give some stats Planets: 9 Hottest Planet: D Coldest Planet: I
1:07 E gets flung into a further orbit
1:08 im pretty sure everyone has lost thier rings by now
1:11 everyone exect for F is in the same orbit
1:16 D is the furthest away
1:19 the most replayed part starts
1:24 the first colision (I into H forming HI)
1:33 C and F crash
1:34 HI joins the crash and C gets out the crash
1:36 C crashes into the Star PLANETS NOW: A, B, D, E, G, HI

2:47 i love how the cyan planet got yeeted into the sun by the green planet and just exploded, with its corpse making an enormous ring for the green planet

[DanAviationFSYT]

Its very lovely to see the planet keeps the remains of his brothers and sisters as his rings at the end

[JamMyLolk]

The simulation ended with 2 surviving planets, One in which a murderer and the other a surivor so i decided to give them a name

1. Ringy - the only ringed planet in which was made by a triple planetary collision, which was made a monster, killed most of the surviving planets with it's gravitational pull.

Birth of Ringy - 1:35
Amount of kills - 5
Lifetime - 7min & 11sec

2. Speedy - the fastest planet in the simulation made from a bump between two planets, made several dangerously close flybys with Ringy and the "Gravity Ball"

Birth of Speedy - 1:44
Closest to death - 8:14
Flybys near Ringy - 7
Flybys near Gravity Ball - 8
Lifetime - 7min & 6sec

i was bored so i made this

[petterlarsson]

3:13 man it would be satisfying if that lightspeed planet actually hit

[SpaceSimulationToolkit]

Cool! Please, add this video to the STEAM community videos

[protactinium]

1:34 also love how cyan planet number 2 does a triple collision to green planet 3 and 4, then cyan planet smashes to the sun and the merger barely survives, plus it created a planet that orbited very close to the sun at 2:13

[Data-se]

2:01 a planet enter star's roche limit
2:12 again
2:48 planet collide with star due to gravity
2:51 ring form to the closest planet
3:03 planet with ring enter star's roche limit but still survive
4:02 planet acceleration due to another planet's gravity
4:29 again?
4:54 again (3 times)
5:21 again (4 times)
5:50 again (5 times)
5:59 again (6 times)

That is a stupendously big ring system!

[Xo-gdcg]

3:15 that planet steals a ring and dies seconds later

[kivikallo]

The smaller planet finally shattered at the end :, (

[GodofWeird]

How do you do this, I’ve got the simulator, but I can’t make a protoplanetary disc without it collapsing or anything.

[mahdiyarrazavi-ijhh]

I love my eyes stares at the simulation and seeing how it works

[carolynallisee]

The more of these I watch, the more I appreciate that our 'orderly' solar system is the exception rather than the norm. Of course, what we see here may well represent the first one billion years of the solar system's existence, rather than a longer timespan, so nothing has had time to settle down. However, watching the chaos unfold gives you an inkling of how, say, Venus ended up with a retrograde orbit.
The thing is you could run this exact simulation a million times over, and the result will be different every time. Our forebears liked to think everything was simple, and followed a predestined plan, a bit like clockwork. However, we are learning, much to our chagrin, that rather than running like clockwork, which we far prefer, the guiding principle behind everything seems to be random chance and chaos.

I love how one planet is trying to eat another but another one saves the planet by using its gravity

[spaceboi]

The core: ''If you can't beat them, eat them.''

[person]

WAIT THERE IS GRAVITY BETWEEN INDIVIDUAL PARTICLES NOW??? YES YES YES YES YES YES

[loginman]

Friction looks a bit high, but awesome nonetheless

[protactinium]

Damn 2:49, the green planet must have hated the cyan planet and slingshotted it straight to the sun, then bro literally stole its corpse to a ring

[RedRing]

this is like a binay star formation because the star in the middle is smaller than the "planets"
