Multiple-Galaxy Collision Simulation

[SugaredBacon117]

Its deliver hope from halo reach btw. The blue spartan is called kat

[CCsir11]

I would imagine when we would be less than a couple of centuries from our milky way(galaxy) and Andromeda collision.... The song of deliver hope, live action trailer for ODST and the music from avatar where the blue guy falls of the human ship during the collision :(

[rizer912]

AHH THEY'RE CRASHING INTO EACH OTHE-no wait...that's Captain Falcon and his team training, CARRY ON!!

[k151s]

WOW

[vxt1024]

galaxies are dancing!

[BLA2K102]

there has got to be (proboly) hunreds of star collisions some might go to supernova and one of them might make a black hole. then that will affect the WHOLE process

[nashertheatheist]

@BLA2K102

Not necessarily. A supermassive black hole might disrupt the process, but they accumulate over millions of years. No single star becoming a black hole would disrupt it in the slightest. Galaxies are riddled with black holes.

Black holes are only as massive as the part of the star that made them, plus other matter they pick up. The black hole at the centre of our galaxy probably took an incredibly long time to reach its current size.

[WorldWalker128]

How come we never see a simulation for a DIRECT collision? Given the 'law of averages' it's bound to have happened at least once.

1 of 3 effects: 1. They bounce off each other over and over and eventually come to a stop on one another. The stars and planets would likely still scatter regardless.

2. 1 or both would shatter on impact creating hundreds of black holes sucking up all.

3. Upon impact, all the gases collected would ignite and create a Gi-normous nova that'd blow everything up.

[MovieMagicMaster]

Somewhere in space....this is all happening right now.

[graveF34R]

GIZMODO

[NeverevenStudios]

You got your Andromeda into my Triangulum!

You got your Triangulum into my Andromeda!

[synnr666]

Yup, that's how it happens. I can attest from witnessing first-hand.

[kosilveriarn]

I'm sure we will do this for fun or in celebration of NYE 20 billion, once we figure out how.

[feiggit]

this kinda makes me jizz in my pants

[AlgeKalipso]

I sometimes wish entropy ran backwards. Why U always end up Elliptical??

[rottencranberry]

watch out! Gigamasive black hole is born!

[acraze21]

Wow that thing spit out stars in all directions

[halomaster22323]

MEGA GALAXY!

[rulz492]

When two galaxies collide very few, if any, actually collisions between stars occur. This particular simulation models a "collisionless" system. You introduce a 'softening' term to the force calculation to stop the stars from behaving unrealistically in close encounters.

[prime67023]

"there can be only one"

[georditrapman]

did u use universe sandbox

[typesix]

badass

[XxdragicexX3]

lol at 0:45 you can see the galaxy opening its mouth to eat the other one LOL

[SseBb]

This destruction seems so elegant, it is a beautifull dance of destruction.

[airman13579]

@SseBb actually hardly any destruction occurs. stars are so far apart that it's only an illusion of them colliding. what's happening is that they are all getting absorbed into a dense mega galaxy

[SseBb]

@airman13579

even more beautifull ;)

[Dextomus]

@SseBb Think of it like sex... Even though you are inside somebodys body doesn't mean that you hurt them ^^

[TheMrSlappykins]

could you imagine being a star in there lol especially getting flung out into random space

[inimicalODDITY]

I wonder how many civilizations have come to end from a collision like this.

[sim5191]

you can see a so called "super galaxy" forming in this simulation

[Muthsera80]

As a layman I got to ask. Whats the driving force behind these galaxies? And what happens when they combine? Does it combine and multiply the attractive force or does it stay constant? In other words. Does it create a greater dent in the fabric of time/space.

[misterbuckethead]

gravitational force is what moves them. Galaxies exert a VERY large net gravitational force on objects.When they combine and everything becomes somewhat stable, yes the force becomes larger. The formula for gravitational force between two objects is (G x M1 x M2) / r x r. so the smaller the distance the greater the force. and yes space time is changed. The reason that light bends around objects due to gravity is that space time is distorted by gravity. This is explained because light has no mass

[Muthsera80]

@misterbuckethead

I appreciate the response.

But I thought that the center of galaxies was driven by a black hole? Do I misunderstand that? If it wasn't, I could see how the mass drove the motion, but it doesn't make sense if it's driven by a bh.

Secondly, isn't light a form of matter because it bends around distorions in the space/time? Isn't that what Einstein say?

[misterbuckethead]

@Muthsera80 Yes. Black holes are simply stars that have become so massive and dense that even the light emitted by them cannot escape. However, photons do not have mass. Light always takes the quickest path to any object. If you were riding a photon, it would appear that you are traveling in a straight line, but actually space time itself is curved by gravity.

[zairuku]

Basicly, for the sentient species that survived, would cross over to other planets while they are so close and see whats going down and what to do next. JEEZ the size of that super-galaxy at the end XD

[gg5190]

This is a simulation of something that would take millions of years to happen, if it were ever were to happen. Why? The distances that galaxies cover is VAST! To the person below: It would be very unlikely for stars to "Crash" head on. Something more realistic would be a binary system...etc.

[plsspareme1]

i think the star might crash head on as their intense gravity pulls at each other and when the do, the probably expolde or get bigger or somrthing and have even more gravatational pull and the whole universe would be come one and i agree with the guy below me.....

[fingerprint211b]

The universe is a cruel place. Better have good shields and working warp engines.

[Grykus1]

And a map. ;)

[selearemus]

we need hyper drive,worm hole,shields,laser weapons,ion weapons and plasma weapons

[2012TheAndromeda]

is that supposed to be seyfert's sextent?

[Zombe3]

At the end it is 1 mega-galaxy that is already spinning...

I can sense harmony in this... And thus, all shall become 1, etc...

[selearemus]

harmony? that's destruction,murder everything u want but say something evil like some1 is playing with them and laughs

[JonGre93]

I believe this is very Deadly. If it would EVER happen, bigger chance a Black Hole will appear close to us or something.

Humanity wont see one for atleast 100 Billion years, maybe more. If we're even around by then.

[maitrelame2]

In 100 Billion years, the universe would have collapsed, so nothing will be there ^^

[selearemus]

how if the universe is infinite or u believe in big crunch which is stupid.

[maitrelame2]

@selearemus hum actually you should check the definition of the universe...

The universe is the shape of the mater and as far as we know it's not infinite and every N-body model show that after expanding it always colapses...

[gpitts9261]

@maitrelame2 Actually, the force of gravity is not strong enough to pull the entire universe into a big crunch. modern research shows that the rate of the expansion of the universe is increasing. So we are either heading to a big chill where galaxies slowly run out of hydrogen to create new stars and the rest of the universe that is not gravitationally locked with us flies further and further away.

[gpitts9261]

@maitrelame2

continued... then there is the big rip which states that as the rate of expansion increases it will eventually get so great that gravitationally bound objects will rip apart as well. galaxies, solar systems, and even planets themselves would crumble as the expansion overpowers gravity and eventually the nuclear forces holding the molecules and atoms together.

[maitrelame2]

@gpitts9261 Which is basically what I said, the universe will run out of energy, since matter is energy, as long as there is energy there will be matter loss, and as long as there is matter there will be energy. You could the same thing with cars, as long as there is gas people will consume it, but once there will be no more gas (if we assume that gas is the only energy we can use) there will be no more cars :)

[ChibiChan1988]

@maitrelame2 colapse and all the matter gets compressed :O w00t another big bang follows and the party starts all over again

[indalecio21]

Black holes are invinsible until it starts consuming something...We may see a black hole tommorow,it is more likely.

Based on what you say we wont see one for at least 100 billion years.They have found a black hole inside Milky way...

[candr]

Actually thay have found at least 2 dozen in our galaxy all ready, the closest is only 1600 ly from earth. And as you say, those are just the ones we can see.

[selearemus]

i believe every galaxy have a super blackhole

[CrzyAlx]

Yes, but your wrong:

In a galaxy the distance between planets is so vast that it is extremely unlikely that our or indeed our whole solar system will go anywhere near another

[LORDKEROTH]

what software?

[fromjuanotojohny]

ouch... haha

[Cwisiee]

imagine what a beauty would such an image be in the night, four milky ways to light up the sky, and how deadly too

[super6plx]

actually very un-deadly.

Once you realise how rediculously small we really are, you notice the space between other planets is incredibly large, and our entire solar system would indeed most likely remain unaffected, with a simulated 0.02% chance of collision

[Cwisiee]

i totally agree about the collision issue, but what i had in mind was the increasing chances of being exposed to γ-rays or other exotic phenomena that occur to "over-populated" spots in the universe, which are lethal indeed, for life as we know it at least :)

[super6plx]

ah, true...

that makes more sense indeed!

ugh, late here and I got a class to teach for 15 mins tomorrow (yr eleven project) my mind is so... gone. lol

[Cwisius]

it is good to keep your mind busy though xD

[deathbef]

I believe it is not true, as this kind of situation could bring deadly chaos to our Solar system. Asteroids and even planet movements could be disturbed because other stars passing by and this could cause collisions. However chance of "head on" collision of two starts is quite small ;-)

[chimychimychonga]

I like turtles

[R4shM4n]

They taste like chicken pie.

[CACBCCCU]

I think it helps if you start with ring galaxy-type clusters, which are basically the results of iterating cosine-modified gravity on a single large gaussian cluster over a sufficiently long time. Something looking like Hoag's galaxy eventually should result.

The ring apparently can evolve to a spiral as the formed core responds to the ring forming from collapse of masses in a sperical region near the second cosine peak, separated from the dense core by 1 wavelength.

[JayDay111]

It is fairly obvious that our current cosmological models are incorrect. So all of these simulations are not realistic representations. It will be many years into the future before we can make simulations such as these with certainty. So saying things like Newtonian Gmm/rr, graviton, cosine peak etc is fiction for all we really know. However, I suppose it is good to shoot blindly into the sky to see what we might find.

[CACBCCCU]

"fairly obvious that our current cosmological models are incorrect"

Let's get back to basis then, sticking with the standard model and looking at gravity.

Check out the paper "Distant Ring Galaxies." It's evident that proclivity towards ring galaxy formation with increasing red-shift is significantly problematic (unexpected) for the single-interloper bulls-eye collisional model. They're kidding themselves. Do they imagine the vibrations of branes colliding in 3-d, or what?

[CACBCCCU]

One other thing -- take another look at Hoag's galaxy, a ring galaxy. Do you seriously believe that those fine helical striations could appear in a ring as ephemeral, cosmologically-speaking, as the ring formed from a head-on collision of galaxies?

[CACBCCCU]

The idea of multiplying Newtonian Gmm/rr rule by a cosine treats the graviton as carrying a gravity force vector that rotates in space analogously to the rotation of the E and M force vectors in a photon, but rotating much more slowly due to having much less energy and doing so in a plane that includes the direction of propagation rather than in the perpendicular plane as with the E and M force vectors of the photon.

[CACBCCCU]

There's a brief segment around 0:25 where one of the clusters forms a tight pair of vaguely-defined spiral arms, but I think if you modify the gravity force by multipling it by a cosine having a wavelength close to the radius of the average starting cluster here, you'll get a more realistic effect.

[Devourer09]

Oh shi-

[phongbong]

i wish my computer could simulate that.  I'd watch that for hours.

[URIZHEY]

My AMD 500Mhz with 128MB os memory RAM and 8MB onboard video card can do this LOL

Using a GIF image xD

[pipotinoto]

what galaxy is that

i have that game

[CrashWhiz]

Heh heh. remember that saying 'ol Mom and Dad used to say... "Its not like the world's gonna end."

[mat967]

and think that each one of those little pixel is a star with planets around it...poor us if it happen...

[VortexCZ]

this is some baddass galaxy now 3_D

[soar313]

woooooow!

[Chuichupachichi]

At 0:17 they look like 4 eggs just waiting to get slimed.

Intergalactic collisions will never happen. Because galaxies look like eyes that have been smoking marijuana. They're all turning red. They're un-colliding

[RayetWolf]

They are happening now, we have pictures of it, lots and lots of them.

[alecTHElion]

you suck, galaxies can collide

[Chuichupachichi]

Galaxian can crash if you reach the furthest forbidden fathomless phenomenons. Where ferocious flying fish frequently fight funky phantoms. Beyond the fireball fields of fifty furry feline fairies from Felandrepon.

"Suck It Easy"!

or

"Take It Sleazy"

[Chuichupachichi]

Thoust sucketh exceedingly as the slurping suckle of a skinny scavenging scoundrel with cock-eyed vision and a scared to dickens gamecock's hard pressed, split-top, dick-head decision.

Flee from this realm

and sucketh no more!

[hotguy6n9]

Multiple-Galaxy Collision = Galaxy orgy !

[Chuichupachichi]

(Multiple-Galaxy Collision = Galaxy orgy !)

Correction - Orgasmic Intergalactic Orgimatron

Next time, think Spockishly "far out"!

[LucaModernTalking]

@hotguy6n9 I was thinking the same...A galatic orgy lol

[PnoyPryD]

it will be that true but it will take million yrs to make 1 together.

[cyberdaemon]

So there must be starts outside the galaxies , right ?

[JonO387]

If so, they are few, and very far between.

[cyberdaemon]

Have they ever found any ? And if galaxies are moving away from each other how can they collide ? Well its not like moving from point a to b , but its more like that spaces between them are expanding or something.And i wonder if the stars outside the galaxy can support planets with life :P

[JonO387]

Not that I know of. Galaxies are obviously not all moving away from each other. On the last question, I would say, why not? If the star got ejected into deep space, and it already had planets orbiting it, they may remain in orbit and they may contain life. Who knows? It's a fascinating universe.

[CCPnoob]

there are many stars ejected out of galaxies - they are just few and far between, remember we see clusters of stars in other galaxies not stars themselves.

Gravity is in a tug of war with dark energy. Where there is more gravity between galaxies they are pulled together but most of the universe is less dense, therefor dark enmergy wins and expands space itself pushing galaxies away from each other.

[theSOADlegend]

you can find these galaxys on google earth 4.3 but its a pain in the butt to find lol

[unurautare]

or if u don't waste ur time u can just type in "colliding galaxies" on google and the name of such galaxies appear there...then put their names in google earth in sky mode...I just did and found the Antennae,very cool btw lol

[theSOADlegend]

wheres the fub in that? lol

[LazyBoy159741]

nice and scary.

kinda reminds me of some cars drifting on ice and trying to crash into each other.....erm....and end up fusing into a...monster truck?lol.

[yuriy609]

Um LokiFatherofFenrir... I would like to point out that a collision like this would take 5000 years, so no. In time we won't see. And on top of that there is the time it will take for the two to come close enough to crash. By that time our race will either be an advanced space fairing race or extinct. Regardless of which, it won't be a problem.

[LokiFatherofFenrir]

It seems like a pairing dance. Galaxies, approaching and going away slightly, only to go back again and merge finally. You can see their long tails, being unfolded vividly, as if they were enticing each others.

Indeed, when galaxies collide, new stars are born, and they fill the darkness with its light as they begin to shine.

[Selassei69]

si hablas es español escribe en español..

[Usiema]

wow, such kindred words. *no sarcasm*

Seriosly tho, it's gonna get REALLY REALLY hot when they all collide like that. Especially in the center of it all.

[dancingnature]

that looks like thats what happened to the mice galaxies

[BlackStarGamer]

I think they loose a lot of stars during this action :-)

[LokiFatherofFenrir]

Yes, but you can imagine that a star is for a Galaxy like cough, or toss some dust. It's perturbing to see thay this could happen with our sun when Andromeda and Via Lactea merge. But I suppose time will put things in order.

[sim5191]

looks like the local group. but smaller.

[LordLebu]

I wish I had lived to see this day ...

[tommybrett]

if this happened i would think the galaxy it would be is virgo A

[Mark96706]

But every star is very far apart from one another, the odds of another star impacting with another are great!

[christaleecarrelli]

All the Bodies of the universe will destroy!!!!

[adjuster57]

Huge galaxy?? Almost as big as the Kansas football coach.

[Camsynth]

that must create one HUGE galaxy!

[KaylinJH]

The milky way is gona collide with andromida in about 3 billion years! :O

[Camsynth]

I know! Exciting!

[mackys101]

waaa whats exciting about that thing ^^ if that time happen we all dusk already haha..

[jolt1100]

the milky way is gonna kick andromida's big fat ass!!!!! go milky way!!!!!

[Camsynth]

i think Andromeda is WAY bigger than the Milky Way. so aliens are probably saying the same thing your saying, but about their galaxy.

[darkdragon7099]

Andromeda is slightly smaller, but they are the 2 biggest of our group of galaxies (the milky way is the king of the group, Andromeda is like the queen, lol).

[Camsynth]

not anymore! its just gonna be one big super king galaxy! lol

[darkdragon7099]

Yeah, sorry I made a mistake over there, I meant that the Milky Way is smaller than Andromeda, so everything else I said is actually the other way around... anyways they are gonna be one giant galaxy when they are done colliding :P

[Camsynth]

yeah i was getting kinda confused when you said that.

[mackys101]

andromeda is bigger than milky way 2 times bigger lol if they collide andromeda gonna eat milky way maybe around 100 billion more years hehe..

[mackys101]

waaaaaa lmao that was funny maybe they saying fucking human galaxy pwned them!! ^^..lol the galay look likes they are fighting in a gangstah way haha.. or are they making up? lmao.

[skald1]

We're already colliding with another: the Canis Major dwarf galaxy discoverd in '03.

[mackys101]

are u serious -_-?

[darksomehandsome]

just imagine the different species we might encounter once planets from our galaxy and andromeda's come closer together...crazy.

[jihadjared]

lol. you guys dont even want to know the hours it took to render this. possibly days depending on who did it.

[nickrowell]

It takes months on supercomputers to do this kind of stuff - look up the millenium simulation. That's a good one.

[BornAtNight]

LOOK OUT! Aw fack... look at this mess.  Who's gonna clean this S#!& up!?

[phoenixshade3]

Looks like the end result is a supermassive elliptical galaxy...
