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.

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.

[@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.

[@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!

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。

[@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

The universe is like fireworks coalesing in a darkened void, its beautiful, no wonder God created it.

[@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.

[@doctorshadow2482]

A nice one. Is the source code publicly available?

[@davidarzeno1177]

Can you imagine what lies beyong the limits of those edges in the begining of this presentation? Would it has any sense to continue zooming out?

[@levanchuong89]

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

[@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?

[@a-ragdoll]

cant wait until normal computers can run these sorts of simulation smoothly

Then the supercomputers will create things even more spectacular. And we will have comments wondering when consumer PC's will be able to create those.

What would a galaxy without stars be? Galaxies are made of stars.

[@FisTheDucc]

@@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.

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.

There is nothing to separate. There is either light, or there isn't, and when there isn't, we call it dark. Darkness isn't a thing, it is a lack of a thing.

[@garypugh1153]

It's my opinion that galaxies are formed and unformed over and over and over and over forever in the past and will continue forever. The energy and matter extend to infinity. No beginning, no end , no creation. Is that right ? Why do they continue to teach " big bang " ??😊

[@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.

[@drdaedalus880]

So rotations of galaxies is dependent on the initial velocities of stars that start to orbit, and would explain why the outer edge is spinning about the same speed as closer to the center. Which makes way more sense than invisible matter.

[@MrJdsenior]

Orbiting doesn't work that way. What you said makes no sense.

[@metaparcel]

It's a dance, really.
