Billions of years in under 5 mins! Now that's a timelapse!
MY GOODNESS THIS IS SOOO WONDROUS!!!
Is the canera “moving” or is everything just spreading out that far??
what the heck are the random explosions?
Por qué esto me aparece en TH-cam music
Entiendo que es un simulador realista del espacio y que en el espacio no hay ruido pero en serio porque está ahí
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.

Why does it not just keep going outward? What force compels it to come back together anywhere?

HOLA, COMOP PODRÍA USAR SU MAERIAL CON SU PERMISOP EN UN PROYECTO GRANDE EN UN CANA DE CIENCIA CON MAS DE 130 MI SUSCRIPTORES? QUEDO ATENO A SU RESPUESTA
Bro has a intergalactic computer
Can anybody explain to me about many little small blasts after the main blast
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.
fantastic! how did you do this? which software did you use?
5 years but no comments😢 thats sad
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.
It only gets exciting after 1:20 that's when all the spurts and squirts start 😍👍
It's a dance, really.
this is 3d keep in mind
Its a simulation, a very realistic one in matematical and teory terms
It looks like the universe is young and it has cyan gasses
Somewhere out there, there is a world where doing the Macarena is considere hate speech.
very nice.thank you. so t this is what growth looks like away from spacetime.
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.
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.
@@Sgrunterundt I never specifically said "with the naked eye". Don't assume.
@@Sgrunterundt Some galaxies rotate the opposite direction - that is leading arms rather than trailing arms. Some have both with one inner and one outer.

this is beauty in motion
I like you at the end, maybe the one on the left of the Milky Way in the one on the right with Andromeda
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 " ??😊
There are no words to describe how incredible the universe is
When i become a programmer, the first thing i will make would be a physics engine just like this.
beautyfull i really enjoy this thank you
Was hoping to see a black hole form in the center of a galaxy, like most have... still awesome sim.
Really amazing work. 😮
I am Patrick Staurt do you know over 70 people had to leave their homes for a New Year’s Eve party and they will return home drunk as skunks slobbering on each other. It’ll be a wonderful day. 🥴
My question is, where did all the gas come from?
Amazing simulation.
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?
Awesome!
So, my lifetime in that is a tiny fraction of second, I born and then die just in 0.00001 sec
El misterio del ser. Magnifica presentación. Me quedé impactada las firmas de vida. ❤❤❤😮😮😮
I need to learn how to make these for the ultimate TH-cam entertainment
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
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.

EPIC
that's crazy bruh
The universe is like fireworks coalesing in a darkened void, its beautiful, no wonder God created it.
does it take dark matter in account?
3d?
Where is god located?
Third fart from the left.
A nice one. Is the source code publicly available?
really makes you think about how this all started
Just an explosion
