ERIS: World's first realistic simulation of the formation of the Milky Way

[BrodeFinePortraiture]

It took:

8 Months.....1 Super Computer.....12,600 Red Bulls....87 tabs of acid.....108,000 Star Trek reruns and one tech actually lost his virginity....unfortunately it was because he never knew he was gay....go figure

[nabeelmerchant]

Yeah right ! The Universe is not that simple.

[iEvoss]

From beginning it rotates clockwise and then other way hmmm..

With logical looking at it and thinking, before all this merging there was something else before ... It's like sucking so what was there in first place? :)

I mean in that actual point place and it's dark it's black it's invisible ;)

Do you know ? I think I know ..

[iEvoss]

it should spin clockwise no? everything no?

[Life28SK]

looks like shampoo foam in my bath :D

[norokelt]

congratz... big effort... i think... :)

i just wonder... why to hell its in violet/purple colours ... Milky Way is white nor?... but... maybe... the... Milka... Cow... is the reason... :P

[hgfggg1]

@norokelt Maybe it's false color.

[siyh]

do u play mario`?

[MrCatbuttgum]

I'm not amused by the breakfast mixing of existence.

[zzz4854]

haha 360p so called supercomputer

[CACBCCCU]

It looks much better in profile, where it's not so misshapen, raggedy and bubble-voidish in appearance compared to a "grand design" or typical spiral, barred or not. Probably took more spinning dark matter than regular matter, maybe mostly in a ramping distribution significantly increasing with distance from the core and spanning the ~100Kly diameter; I can only guess at this point. A lot of pretty good stellar-evolution modelling is said to have gone into it.

[valbonne93]

AMAZINGGGGG

[jorgipogi]

It would have taken me a few hours on a washing machine with some red detergent and clorox bar soap.

[cclagett]

Thank you!

[VinGGfox]

actually, i prefer the 720p or more than that....

[sxaosinz]

i could have done this ...

just record me mixing nesquick with milk :P

[falconclarinet]

@sxaosinz You mixing Nesquik with milk doesn't tell us about the physics behind galaxy formation and evolution. That's why this simulation is so important - in order to create it, we have to tell the IDL program what physics we're using and set up initial conditions, and both of those things are largely guesswork. The situations used to create these simulations are very specific, and the fact that it worked here tells us a lot about the physics controlling galaxy formation and evolution.

[immortalis1001]

Clearly, baby Jesus did it.

[yurianne07]

@immortalis1001 not older, hipster jesus??

[immortalis1001]

@yurianne07 Absolutely not, Baby Jesus created the Baby galaxies to play with as written in the scientific journal of the day called the Bible. We do not need some silly video game to tell us what happened.

[themadlolscientist]

@immortalis1001 LOL =^..^=

[bryzilian]

The man doesn't understand what is happen with himself here, but wants to understand how the universe was made. He never will know.

[RX120D]

The milky way is a massive drain.

[SotongDJ]

the background sound is too noisy

[LPNeptune]

Where does the supermassive black hole come into play? Does the galaxy form around the black hole? Or does the black hole begin after the galaxy has started to form? Any info would be appreciated

[00D00]

@LPNeptune I believe it forms afterward from collapsed stars merging at the center.

[RynHoard]

All that computing power and the best soundtrack they could come up with is some mixture of a GameBoy game and the song from the Revenge of the Nerds talent show?

[CACBCCCU]

No surprise, dark matter attracts physics flies.

[Pymmeh]

Sent you folks a video of me pulling the plug out of a sink, should save on future computing power. You're welcome.

[BFlogs]

real time is relative

[Aeimos]

Where do I get the sound track?

[jonesatlarge]

I guess I'll get my Jackson Pollack out of storage.

[english2me]

or, let 570 personal computers calculate it in 1 year.

[blacklight25]

@english2me 570 computers all linked up as 1 computer to calculate something!!!! they should have a word for a computer that is so powerful! if i had such an idea i would probably call it a..... super computer?

[english2me]

@blacklight25 lol. i was being facetious.

[blacklight25]

@english2me well now i just sound like an asshole haha

[HalfRaccoonScientist]

I think this is just another cheap dramatization of something we honestly cannot see nor know anything about... in short, its a complete guess of how gas particles SHOULD react to gravitational and other forces /in our minds/. Not fact, just another assumption.

[hazingfun]

@HalfRaccoonScientist Not fact? This isn't a guess you fucking moron, it's physics.

[HalfRaccoonScientist]

@hazingfun ............ This isn't even worth getting in to... grow up!

[hazingfun]

@HalfRaccoonScientist Way to defend your position buddy, nice backbone.

[HalfRaccoonScientist]

@hazingfun Naw, I am just not going t waste my time debating another clueless person in a comments section on youtube. Have a good day!

[kthebeast]

So the Milky Way is a giant cotton candy machine? COOL!

[StopMotionMeltdown]

@kthebeast That's exactly what I was thinking!

[VirDiligo]

I guess the 16:9 ratio didn't exist at that time.

[CACBCCCU]

Proof one can put too much dark matter eyeliner on a flop-hog.

[rawcatslurgeon]

Looks like a dna strand growing/evolving.

[pustolov9]

anyone knows the music in the video? thanks!

[Kamikaze933]

That was me 13 bilion years ago just flushing the toilet and guess what... that's how you were born :)

[Bhanukiran444]

This looks like my cum

wat!!? im just sayin

[endthedisease]

Here's something interesting that just popped into my head. Since the galaxy is more dense with stars and we are on the less populated edge I would think there would be more planets with life towards the center. This might be why we haven't had any contact with alien species.

[filegrabber1]

@endthedisease Closer towards the centre also means more deadly radiation. We can exist because it's nice and calm around here. :)

[konadora]

looks like what happens when you pour grape juice into a washing machine

[qpwillie]

@konadora

I've never had occasion to pour grape juice into a washing machine. Am I missing out on something?

[faro0485]

Ugly galaxy

[Metroidrayquaza51]

We need GLaDOS.... I know she'd be able to do a better calculation of this ^^ oh well, but that will not happen till about next decade. Well, I must say, it is quite astounding to think, that those little things in the start were blackholes... and that we later on started to twirl around it... Creepy XD but wonderful

[BrantFortunate]

if u look closely u can a mystical, omnipotent being carefully creating this . . o wait nvm jk lulz.

[agsiar]

I like the part when it swirls

[THExVETERAN]

SUCK IT RELIGION

[Kaesoism]

@THExVETERAN : If you study more in-depth, in the sciences, then you'd know (or learn, rather) that it's not anti-religion in the least. Science can explain support, and even co-exist with the old miracles and accounts of multiple and vastly different religions.

[rattletop]

MASS EFFECT!

[MonTag666]

Science, Steadily closing the god gaps every day.

[adulby]

grape fanta just explained the universe? 

[MegaAwesomeD]

fucking awesome!

[MR1EAR]

why is that they make the milyway spin....counter clockwise< if that is what scientist think then why do we have many moons spinning clockwise as well as some planets?/OR visa versa(just in our little solar system)

[ehypersonic]

@MR1EAR what happen when u see it from below? :)

[MR1EAR]

@ehypersonic Thats not what i mean I mean regardless as to how it spins...we have moons and planet(s) that spin in the opposite direction....and that is scientifically impossible... whatever spins in one direction will "throw" thing(ie planets and the like) in that direction....

[Bry4nP4n4lig4n]

thats a cool screensaver

[walker2006au]

Im running 4.0ghz it will take me 560 years.

[Halfbluemoon1]

Where can I get this music?

[a575981735977018]

Hey, what a ripoff, you should have run it some more so that we know how it will look like in the future.

I want more!!

MORE !!!

[stephbonnet90]

B.S



[Pivotseb]

and these so called "supercomputers" couldn't go higher than 360p :p

[FourzHD]

@Pivotseb what i have heard, that they storage our porn.

[dharmaone77]

how many particles?

[Razortine]

this music is rather charming. i wonder what it is?

[inachu]

I could do the same in less than 5 minutes. Give me one of those spinning clay jar sit down jobbers and tape down some black paper with a hole in the center and shine a light through it as kids toss pink liquid soap! lol

[bobcrunch]

Real galaxies don't have that many distinct arms. Better go back and rewrite the simulation. While you're at it, rewrite the global warming simulations.

[RitusG]

@bobcrunch It's because it's showing a lot of gases and dark matter normally invisible to the naked eye. Do some research!

[Lurco8]

@RitusG Well I doubt they simulate dark matter you know... It's not like we know anything about it. There are in fact few very good astrophysicists who try to find an alternative explanation for the "galaxy rotation problem".

[bobcrunch]

@RitusG Oooh. Never mind.

[watersedy]

haha it looks like colored water going down the drain

[behrouzsa]

Ugly graphics

Pompous writing

Hokey Music

Just the kind of joke you'd expect out a joke “institution” like UC Santa Cruz.

[clnmyjts]

I seen this when I was a kid...50 yrs ago. yep.. everytime I went to the circus and bought a cotton candy they would use a rolled up paper stick, stick it in the cotton candy machine.. swirl it around and let the sticky sugar candy stick to it..IT look just like that!

[RhondaH]

@clnmyjts Obviously your lack of education in science supersedes your lack of education in the English language. LOL

[Montblanc1986]

this video was a total waste of time. I thought god created the universe and here it was some purple fog and a flashlight!

[fnordist]

@Montblanc1986

Well thats hydrogen not hollywood!

[TheMrSupercluster]

But, will it blend? oh wait...

[mauilandwalker]

Re vid quality- understand every frame is an actual representation of a computation. Doubt a pc can do that in 8mo with 1080p. Please try

[turbominator]

it looks like making cotton candy

[MrAzdesertrat]

Just think about it , these guys actually get paid to come up with this B.S.

[mosasidog]

8 months? those simulation can only be simulated almost accurately by 6 seconds while flushing one's toilet

[Nuel2080]

@mosasidog i don't think your toilet can simulate large amounts of gravity, supernovae, and more than 60 million particles of dark matter and gas. :)

[HeinusHoratius]

It looks like water flowing down a drain... Only it's matter flowing into a black hole... But if a galaxy can only form around a black hole, where did that black hole come from? How did enough matter accrue to form the black hole that then attracts matter to form a galaxy?

[Bayhuntr]

Good job Switzerland!

[fourbabies1]

i saw the FSM in that simulation.

so it's true, there is a noodle in the sky !!!

[Thejhooker1]

makes me feel like im living in a bubble among a whirlpool

[CrankEmpire]

Can we see it in real time?

[467076]

@CrankEmpire lol

[ThinkTank255]

@CrankEmpire

As BFlogs pointed out, "real time" is relative. If you were moving pretty close to the speed of light this simulation would be in real time.

[Xelbiuj]

@CrankEmpire

Yes just hit pause.

[MidnightRedemption]

when milks collide on a blender ..

[OnlineMarketing20]

Wow...

[reisomana]

What type of pc are they using? I want one....

[MrJarth]

forwards not backwards, inwards not outwards, and always twirling twirling

[VladaKG1980]

:)



[RBlazze]

Look's like the milky way is going to flush down to it's center lol

[moot349]

Why is the video so jerky?

[andersemil]

@moot349 not sure but my guess is that the simulation is so immensely expensive that they can only render at very low framerates... but according to Moore's law they will be able to do it realtime in a couple of decades :D

[VladaKG1980]

This is nonsense, old world is only about 6500 years...

[superhamzah85]

@VladaKG1980

Prove it.

[andersemil]

@VladaKG1980 I would write LOL if it wasn't that so many people actually believe this... I hope you're not one of them

[simrousseau]

+5 for content, -4 for presentation. Pressed stop as soon as I saw it wasn't at least in 720p... 1080p cameras are under 100$ now (webcams but still)... what is this crap?

[lookingforajobplease]

Why is this not in 1080P?

[t6yz]

the university of Zurich was made very well known thanks to southpark haha

[touristtam]

Nice. Thanks a lot for sharing. :)

[FreezeProduct]

8 months calculating...and not even in HD.

Where's Michael Bay when you need him ?

[managarm1349]

8months calculation time on a supercomputer...lol epic piece

[prozacula]

@kidgico - I made the music in 2 hours on my Korg keyboard

[prozacula]

@rischini - it's music I made myself on my Korg Karma.

[ecksor88]

Science is beautiful.

[virgillevinger]

The soundtrack is the actual noise made by the creation of the galaxy.

[ChrisWithACam]

I THOUGHT GOD MADE EVERYTHING! /sarcasm

[kidgico]

Anyone got the name of the music used in the clip?

[MrJarth]

@kidgico use your eyes

[kidgico]

@MrJarth I did, I don't see it in the intro nor mid video nor at the end nor in the description. I must have bad eyes. :(

[meyerjac]

Bow down and worship at the foot of glorious Science!

[Skindoggiedog]

This makes assumptions about my personal PC which I'm not really comfortable with.

[fizzlemanizzleable]

@Skindoggiedog ok when you come out with a computer simulation of the formation of the milky way in 8 months on YOUR computer and show me you can troll all you fu*king want

[7777phoenix]

@Skindoggiedog This makes assumptions about your personal personal computer? :Đ

[Skindoggiedog]

@7777phoenix "This makes assumptions about your personal personal computer? :Đ"

Not telling you; that's personal.

[Skindoggiedog]

@InsideOutN Yeah, you didn't quite get it.

That's okay, though. You don't have to :)

[InvictvsNox]

You would think a supercomputer would have a decent enough GPU to reproduce a video of its computations in a more acceptable/tolerable framerate.

[elleckz]

@InvictvsNox i believe the reason the frame rate is so slow is because of the method by which each frame is generated, rather than the gpu of the computer. In physics at uni we looked very briefly at this kind of thing, the computer uses iteration, each frame applies some physical laws (perhaps gravitational force if simulating like, planets moving around) to the previous frame and works out the positions of the objects, and i suppose this one might just have shittloads of objects

[truckcompany]

@InvictvsNox

Two right, I bet even my 1gb Video Adapter could out do that puppy in no time.

[M3aaaqHD]

@truckcompany Read the comment before you.. he makes a good point

[bigbezet]

@InvictvsNox I don't think you understand how this was generated. GPU? In a supercomputer? Read about grid/distributed computing. If they increased the desired framerate, they would increase the time needed to render this animation because they would have to render more frames. Each frame is the result of the computation, there is no GPU that creates a video animation based on that computation.

[Lymos524254]

570 years? Challenge accepted!

[tobiasmerriman]

Amazing. now re-do it to this music. Open youtube in another tab and silence this one and check the diff in emotional response: =LoVjSeb4aYA

[tobiasmerriman]

Amazing. now re-do it to Ellie-Goulding Lights Bassnectar Remix. Amazing. now re-do it to this music. youtube - LoVjSeb4aYA

[evilgeenius2]

It would be really great if they could generate a high definition version of this video. I'm guessing they could do another render pretty quickly as the long calculation time required would have been to calculate the position of the objects rather than to create the render..

[pcuimac]

Geil! If I am allowed to say so ;)

[mjusiqtube]

Beautiful!

[1thermon]

Impressive. Now all you have to do is demonstrate that dark matter actually exists because presently there is zero evidence for it.

[tedhellcaster]

they should have shown a simulation of true color not false color

[jtantley]

i hope this music isn't what God was listening to

[Stickuz]

Nine months to render and its not even in HD?

[timortega95]

looks like cotton candy in the blender XD

[Pearlcussion]

did anyone else hear "time to keep moving" in the music? (Blast Corps 64 reference)

[sOulrOckmelO]

it looks more like a milk shake to me

[gears6515]

pause video mute video, look up halo theme music now start both videos enjoy!!

[twowheeler1300]

I'm as big a fan of space studies as anyone but I just don't get this. Seems like a lot of effort for very little in return. WTF?

[thorkelson]

@twowheeler1300 up until now noone was able to get the correct shape of the galaxy with a simulation based on what we know of galaxy formation, now they have got it right so we can be confident that we have the right picture

[twowheeler1300]

@thorkelson Hey Thorkelson. First of all thank you for the explanation. I understand it's important to get things right. I suppose I still may be missing something here. I just don't see a return on this investment of time. Perhaps I'm a little shallow but I much prefer the ending scene of "Men In Black" (I know it's not real)...

[charlesfrith]

The spin is not representative surely. Way too fast.

[suckittomcat]

Such a waste of resources. This is theoretical, not fact. I can get behind SETI for sure, but I see no benefit here. Pollution and our reliance on fossil fuels are two of this planet's biggest problems. Not to mention population explosion. There are more people on this planet now than the total number of people who have ever lived and died here. What will we feed them...hard drives and RAM chips?

[TheMasteratLink]

@suckittomcat Your right, staying stuck in the past has always been the best course of action. Who needs science when god loves you? He'll protect us, trust me.

[MikeTaylorLives]

@suckittomcat

Anyone who takes an either/or view when it comes to science and scientific development is a person to be pitied. There's no reason that time can not be spent both exploring the universe at large AND figuring out how to feed the world population. In fact it IS being done right now. Furthermore, it's a matter of record that developments in seemingly unrelated fields can have profound impacts on each other.

[MikeTaylorLives]

When you go to have your next MRI done at the hospital, thank those scientists who originally developed that same technology to look at stars.

[suckittomcat]

@MikeTaylorLives I will thank them. But I stand by what I said about this particular video.

[Plasmadyne1]

Who pulled the drain plug on my bubble bath!?

[olimario]

GOD IS AMAZING lololol

[secretident2]

This is what happens when a large pile of dark matter hits the fan.

[PrehistoricPinup]

@00Weedman00 Why? Cancer and aids just affect humans. One small organism on one small planet. Insignificant. It is much more important to understand the rest of the universe, and especially how our galaxy works, so that future species on this planet can use our research for themselves.

[secretident2]

@PrehistoricPinup

And this is much more important than our own well being at the present why?

[fantamize]

I think this is very interesting and cool but it would have been way better in 1080p??? All that computing power and no 1080p video???

[mute]
