The stars involved are sufficiently far apart that it is improbable that any of them will individually collide.
The result of the collision between Andromeda and the Milky Way will be a new, larger galaxy, but rather than being a spiral like its forebears, this new system ends up as a giant elliptical.

Well, that's going to effect the trout population.

Great something else to dread irrationally...

First description of this future event I have seen that is accurate.
rossimus
Many stars will be flung out into deep interstellar space though, which will make any orbiting planets have dark starless nights forever
PastryRaven
I heard the term they're using for the theoretical new galaxy is "Milkdromeda" and I think its stupid

Fun fact, this is predicted to be the largest and most expensive beyblade battle in history

Why does everything have to happen to me
stoutde
I wonder how that's going to affect planetary orbits around the stars that don't collide.
vindik8or
It won't. You can essentially count entire star systems as just the star for this level of interaction.

Life has only existed on earth for 3.7 billion years.

We're going to need a shit ton of ranch dressing for two galaxies.

Tell your folks I says hi
suiseiseki
The resultant galaxy is/will be called Milkdromeda. Which is a little lame if we're honest.
Matsuuu
Androway soubds cooler.
FabergeBurrito
Milkdromeda sounds like a Michelin star restaurant & Androway sounds like it's fast food counterpart started by their low budget brother.

"its inprobable the stars will hit one another..." but don tell me there wont be massive gravitation spikes around...or will they just merge

Oh Lawd!

The merger has already begun! https://www.sciencenews.org/article/andromeda-reaches-out-touch-milky-way
Imalwaysready
Does this mean that the energy required to dial the eighth chevron will be reduced in future seasons as we get closer!?
iwishihadchickens
Fascinating! I read in another article that our furthest star is halfway to andromeda, and that a galaxy passed through us already.

Great!!! Another thing to be anxious about.

not exactly. https://www.universetoday.com/107322/is-the-solar-system-really-a-vortex/
iwishihadchickens
TLDR: the model demonstrates we’re moving through space which is the intent. (it’s not a vortex, it looks like that because of the angle)

Wheeeeeeeee!

Can an astrophysicist answer a question, please? If everything in the universe is moving away from everything else, how can this happen?
Myrealnameisunusual
Also, our galaxy cluster (the local group) is bound together by gravity and will form the extent of our known universe many trillions of
Myrealnameisunusual
Years from now. Everything outside of the local group will red shift to nothingness. So any future civ will be unable to determine big bang.
Myrealnameisunusual
And hence will be unable to determine origin of the universe. To them the universe will be made up of the local group only. Nothing outside.
KingOfTheImgurians
That's cool! I don't know much of this stuff, so learning something new is great. Thank you!
Myrealnameisunusual
My pleasure, liege.
FishDimension
Stuff is not actually moving through space away from everything else. It's the space in between that is expanding. Think of drawing a bunch
FishDimension
of dots on a balloon and blowing up the balloon. All of the dots will appear to move away from each other, and yet they all stay exactly
FishDimension
where you drew them on the surface. The balloon's surface is a 2D representation of what the universe is doing in 3D space.
FishDimension
Now I'm not actually a physicist so I may be wrong but as far as I know, exactly how this happens is not really that well understood.
FishDimension
Apparently, empty space has some sort of inherent energy that causes it to constantly create more of itself. This energy is what's usually
KingOfTheImgurians
Thank you! That helped me to understand it. You, sir/ma'am/sentient bowl of petunias are glorious.
FishDimension
You're very welcome!

At least it won't be in a spiral anymore.

The Yacht Money!
MrKomisiripala
Yes, we all know about Yacht Money. but what about Second Yacht Money?
FrogBotherer
It roughly coincides with the Sun ending its main sequence and growing into a red giant. So there likely won't be an Earth to worry about.
onecowboytoo
What if, hear me out now, we put a hyperdrive on the earth?
AtsaMattaForMe
Contundo
Even if it was happening right now it’s not very exiting. There is so much empty space so there not really very dangerous.
Imalwaysready
So we all die out right before the big show happens? Just make it through the previews and kaput? Well screw that!
HenryLongfellowIII
The way things are going we'll kill each other off entirely and re-evolve many times before that happens.
JustAnInternetPerson
I heard a podcast with Brian Cox recently and he said new calculations indicate that the earth will not be eaten. Still toasted though.
chiechien
Every new model seems to change the outcome slightly. "Oh wait if we just include this, Earth just moves to a higher orbit. Unless... Oh no"

They're just trying to make it sound less sexual so that it can still be taught in the Florida public education system.

This video is sped up a bit

Probably reversed too
Popnitro
At least 9 times.
AtmaDarkwolf
Only a bit. Be exciting when it happens though, watching stars zip past us :P
BlahBlahTurtle
Not to scale either.

Not even a banana...
ShamelessSeamus
By my math: 1.3797e16:1
ShamelessSeamus
That's from video start, to collision at 8 seconds, assuming 3.5b years.
ProfessorChaos
Just a bit. But who’s filming it is my question!?
willfulwizard
We’ve got a few years to get a camera into position. No problem at all!

We are seeing it now, but it occurs in our future. Obviously it's the doctor...

We need a different narrator, Freeman really bummed me out with that World Cup speech...
DavidBrooker
Fun fact: when the Andromeda and Milky Way collide and merge, odds are that not a single pair of stars will actually collide.
cryborg
However, passing stars could move planets around within our solar system.
Filanwizard
Space is big
DavidBrooker
(Meanwhile, the odds of the solar system being *ejected* from the galaxy are *not* negligible: 12-15%.)
onionninjas
that’s mildly discomforting
AbstractArtemis
99.99% chance that their orbits change, climayes become extreme and erratic, and all life is destroyed. I'm glad the dirt will be safe haha
Matsuuu
And isn't there also possibility of the big black holes in middle of galaxies starting to suck stars into them.
Hashbrown123
Imagine getting sucked off through a hole? Hell of a way to go.
AbstractArtemis
I think technically you fall into a big hole. You're not sucked
Hashbrown123
https://m.youtube.com/watch?v=AbSClDu98-c In the end they clearly talk about getting sucked off in a hole.
DavidBrooker
Interestingly, the merger of the two SMBHs at the centre of the two galaxies will *increase* orbital energies on average, pushing stars 1/2
DavidBrooker
further out on average. But of course, SMBHs ingest mass all the time, and some stars will likely be consumed. The reason we can 'see' 2/3
DavidBrooker
them at all is the mass falling into them, before they reach the actual horizon. 3/3
