Simulation of galaxy formation

[@bakerbaker1959]

I have seen pretty much every supercomputer simulation of galaxies, the universe, galaxy clusters, and filaments, but this one is the most beautiful that I have ever seen.

[@minnowpanda304]

I can believe it, not many differences lol

[@gonzales2011]

Love this one too!

Yea but you can only see those colors with an infrared camera, right?

[@w花b]

Idk, depends what they did with image processing​@@Bennahr_Fett

[@WatDoino]

Amazing simulation! Mind boggling this dance of gas, stars, explosions takes place over billions of years!

[@irelae]

And the fact that we’re in the middle of such a beautiful display!

[@VestedUTuber]

It's crazy how violent this looks at these kinds of speeds, but because of the massive distances involved at normal speeds things would barely even appear to move.

[@Sgrunterundt]

Things would not appear to move. Period. Not without precise instruments and tracking across decades. There was a time we could not be sure if galaxies actually rotate the way their spiral arms seem to indicate, it might have been the other way around when all you have is a still image. Civilizations could rise and fall in between the frames of this simulation.

[@VestedUTuber]

@@Sgrunterundt I never specifically said "with the naked eye". Don't assume.

[@erratic88]

@@Sgrunterundt Some galaxies rotate the opposite direction - that is leading arms rather than trailing arms. Some have both with one inner and one outer.

[@delicatedirector3694]

really makes you think about how this all started

[@gp5313]

Just an explosion

[@DavidGuettaGDIversion]

MY GOODNESS THIS IS SOOO WONDROUS!!!

[@Braitaman]

Impressing! There is something natural about this art, it emergeses realness. I like it very much. 10 (European) mrd. years in less than 5 minutes can be so beautiful.

[@vidstige]

Beautiful! Love the camera work and the little "poffs" when (presumably) stars are born.

[@FernandoCruz-qz5sc]

That was beautiful. It is known that most galaxies take around 1 billion years to complete a complete rotation (outer arms). These simulations make it clear that many more than 14 rotations have to occur for a astonishingly complex structure like the Milky Way to settle down and become the beautiful monster we live in.

[@TheMAGICMAN1973]

Thank you for an absolutely amazing animation. It makes space more interesting and photos of nebulas more enjoyable to watch.

[@jiujiu]

These simulations are incredible

[@busteraycan]

New PBS Spacetime video sent me here. Amazing work. I have no idea what ASURA is but I wish I did...

[@jadenpietrzak2509]

There are no words to describe how incredible the universe is

[@bumbo222]

Absolutely incredible! It starts by seeing how the cosmic filament forms and then we see how galaxies naturally want to be flat because after billions of years of stars gravitationally affecting their neighbors or crashing into each other, there is a net angular momentum of the entire system.

[@peterv4209]

very nice.thank you. so t this is what growth looks like away from spacetime.

[@KAKU560]

銀河の衝突→星間ガスの圧縮により星の爆発的生成→大量の超新星で星間ガスが吹き飛ばされる→銀河に新しい星が生まれなくなる→楕円銀河で安定。 うまくシミュレーション出来ていますね。

[@davidarzeno1177]

To me this represents the dynamics of galaxies in the flow of spacetime at a speed that we can perceive and understand. I think it is exactly the same on the quantum scale, just that the this is in an exponentially higher speed difficult to perceive and quantify. Congratulations!

[@funiman6783]

This is beautiful

[@kavyachari4968]

Amazing simulation.

[@physixtential]

This is the most interesting sim I've seen. Those explosions are SPH instabilities right? At first I thought you were actually simulating supernovae, but later it was obvious that it was some sort of numerical instability.

[@nicolarighetto3767]

Well, it kinda resembles the effect of supernovae and O-class star cluster winds

[@manda3dprojects966]

So, my lifetime in that is a tiny fraction of second, I born and then die just in 0.00001 sec

[@jerryz1006]

It looks like there are lots of singular movement, which reflects the inaccuracy in the simulation.

[@mrzorg]

Was hoping to see a black hole form in the center of a galaxy, like most have... still awesome sim.

[@monstercolorfunco4391]

Can you do an Oort cloud sim please. there are so many artist images of Oort cloud of a very similar geometry, then a galaxy sim can give us the same geometry as the art images? Including cross-section views. The Oort cloud images used a physical equation base, so we can use them as a 3D gravity cloud visual?

[@ericjorgensen6425]

Now imagine that one of the galaxies develops intelligent life in the form of a type III civilization that can control the mass and motion of stars. How could such a civilization impact galactic evolution?

[@davidarzeno1177]

I don't think a Type III civilization would be interested in controlling anything. She would see that everything works perfectly as it is. It is more our civilization that should overcome the compulsion to control in order to survive if it wants to survive to itself.

[@tacitozetticci9308]

@CyberBallAnimations I'm pretty sure he's Italian and yes we don't have a true neutral gender in our grammar so we call everything either a she or a he; he probably got distracted and applied italian rules while writing that bit. A civilization is a she, the sun is a he, the sea is a he, the moon is a she and so on.

[@megamaser]

@@davidarzeno1177 Nobody would develop a type III civilization unless they were very interested in controlling everything.

@@vaahtobileet not only, they are made out of stars, gas,dust , blackholes and planets. But there is no galaxy without stars xd. If a galaxy has gas in it and its dense enough in different regions, stars will form so do planets and blackholes cuz they are starcorpses:D

[@vaahtobileet]

@@FisTheDucc well yes, my point was that a galaxy by definition has to have stars in it, so they must form first for there to be a galaxy.

Is it calculated by super power Computers base on the known physic models or it just an illustrative video?

[@gabrieldelatortilla1]

so the universe is very chaotic and we're but a spec of a spect dust in all of this and it all seems so still and slow and somewhat stable to us simply because WE'RE too slow for the universe

[@MrJdsenior]

Too quick, actually. During a human life, basically nothing happens in a galaxies evolution. You may go around the sun 100 times while still breathing if you are very lucky, but even then, you've only traveled about 1/2,500,000 th of the way around the disk. A galactic year is a long time, at our orbital distance.

[@imfermion206]

Can anybody explain to me about many little small blasts after the main blast

[@NightRunner417]

From what I understand, they are caused by instabilities in the math calculations, specifically "SPH Instability". It depends on how deep the simulation is simulating of course, but I've seen mention many times about mathematical instability causing these effects, rather than them being a purposeful part of the sim.

[@MrGN-yy6op]

that's crazy bruh

[@vinniepeterss]

❤

[@T0P0FTH3P0P]

does it take dark matter in account?

[@taureanwooley]

Some of the explosions appear to be faster than light considering how quickly it moves from one area to the other, while losing its mass in the process.

[@bensongxisto2374]

Given the time acceleration I'm not sure

[@taureanwooley]

Yes I understand the acceleration, but the acceleration is in billions of years and some of the distances are millions of light years. Might be the only way for it to move that fast, the constant loss of mass creates a continued push towards a terminal velocity in a vacuum.
