When I was a kid, 60+ years ago, I had a science book for children that had an illustration of two galaxies passing through one another. It explained that there was so much distance between stars that the two galaxies would pass through one another with no effect. Now I see photos of galactic collisions and the two galaxies tearing each other apart. The universe is so much grimmer since then.
The stars don't get hurt so what's the problem? The dish shape is kind of nice, but I don't see what the big deal is. Life would go on untouched. Think of it as a great many friends arriving. Besides, after another eight billion years it will have a sexy shape again.
Bobby Albert I still enjoy the game. In some aspects I enjoy it better than one and 2. my favs are 3 and thus the new one based on a real galaxy just made the game more interesting. the newest game could include the collision or maybe its after and they need to go to the Titan.
The first time i see Andromeda it really got the wheels turning , the visual i saw actually left before humans walked ...a real thinker ! ..beautiful !!
**Andromeda and Milky Way merging** Andromeda stars and planets : *WEEEEEEEEEEEEEEEE* Milky Way stars and planets : *WEEEEEEE WE'RE PASSING BY SO MANY STARS*
The real question is: where is the Andromeda galaxy RIGHT NOW? The Andromeda galaxy is 2.537 million light years away from the Milky-Way galaxy. That means we are looking at Andromeda as it was 2.537 million years ago in the past! Andromeda is not just moving towards the Milky-Way, it is ACCELERATING. As it gets closer, the gravity between the galaxies gets stronger, and since there is no terminal velocity in space, it just keeps accelerating. So Andromeda right now is much closer to the Milky-Way than we can see. We can only see where Andromed WAS IN THE PAST, 2.537 million years ago!
Congratulations, you get a F for Fail at instilling mass panic via science. The Milky Way and Andromeda are estimated to approach and collide in 4.5 billion years from now. That means Milky Way and Andromeda are moving towards each other so slowly that it's going to take them that long to cover roughly 1.25 million light years, as the masses of both galaxies are vaguely equal and so they will meet each other at a point in the middle. So genius, how much distance do you think either galaxy covers in 2.5 million years? Probably no more than a few light years. If we high ball with the figure of 3 light years, that means we are also that much closer to Andromeda since we are moving towards it as well. So in total, Andromeda is ~6 light years closer to us than we see if we high ball it. So are our light-speed-impeded observations going to mean a much faster collision than we can see? No, because galaxies don't move at the speed of light. In fact, the two galaxies are moving so slowly that Earth's rotation is moving many times faster than them. So no, you are completely wrong. At these distances, light-speed is irrelevant. We are moving towards the collision far too slowly for that to be a factor.
@@cryoraptora303tm2 Not really, as the title of Anton's video state's maybe we are closer to Andromeda that we currently think. Anyhow if humans still exist when the main stars and planets collide the odds of our planet colliding with any other objects are still very slim as the space between planet's are huge. Most likely we will merge without any serious impacts. (Sorry about my grammar English is not my native language)
If I were to guess, I'd say Milky way's halo is also bigger.Keep in mind other further galaxies are showing us their past, and the closer they are the more present development they represent (like a picture of universe's evolution). It should be no surprise that we can observe more super nova evidence for Andromeda than par galaxies. it always made be question in my Astronomy class, how can they be sure that something X light years away is doing what we expect now compared to X years ago? We just assume everything is constant. Even my teacher cannot answer my problem with this...
Galaxies that are gravitationally bound are close enough that their acceleration towards each other due to gravity is fast enough to overcome the accelerating expansion of the universe. Also, in the past the expansion of the universe wasn't accelerating (around 5 billion years ago), so during this period gravity could act over much greater distances (since gravitational force carrying particles seem to travel at the speed of light). Now, since the expansion of the universe is accelerating, gravity from very distant objects isn't only weakened due to the huge distances, it has no effect at all. So everything starts moving away from everything else, except for things that were close enough together before expansion started accelerating.
Like the pressure you feel of an 18 wheeler truck in a freeway that is about to pass and push your little car by. I believe it's true what your saying it's already touching our galaxy.
After the solar eclipse all kinds of weird things have happened. First hurricane Harvey, then Irma right after, and then from a different video I saw that we might pass through a space cloud within the next 20 years that will wipe us out. Them I find THIS. I'm actually shook
Jeez, I wish there were some competent people in these videos. All the comments are dipshits begging for likes or are trying to gain sttention by being "first." There are literally 5 "first" comments (or the like) as of this post. I want to hear people's scientific thoughts on this video.
don't forget that both the Milky Way and Andromeda galaxies have orbiting dwarf galaxies that have recently (in astronomical terms) collided with the "parents" it wouldn't surprise me if the tendrils of dust that are the result of the collisions are already interacting.
It sounds like you're saying that the spheres of influence of the two galaxies have started to interact. If this is the case, the collision has indeed already started, and as they get closer it will speed up until things get REALLY exciting.
All it means is particles from Andromeda are hitting us and vice versa. The pair aren't physically colliding anytime soon. That will still take billions of years.
Isn't it crazy that both the MilkyWay and andromeda, while being unfathomably huge to us, are barely even specs on a universal scale. These galaxies are huge and contain hundreds of billions of stars, some if which I assume supports life, Plenty that are probably much smarter than us. But to think that if these two galaxies vanished, the universe as a whole would look almost unchanged is fascinating. And for all we know the universe might be tiny too, It could just be spec with in a whole cluster of universes much bigger than itself. I know this is just common knowledge to a lot of you. But when you sit back and think about how small we are, its mind blowing.
Makes sense. I was a bit worried I was walking into another asinine video with illegitimate claims. Our solar system is actually far larger and has much more influence than we initially believed as well.
In the past they say that our galaxies have collided before so a string of matter being pulled upon by both galaxies makes sense as the two galaxies pull upon each other the material is caught in the gravitational pull of both as the two near each other.
What are you talking about? Who's 'they'? We have no evidence to suggest that we have interacted with Andromeda in the past. Maybe we have passed by each other and exchanged dwarf galaxies in the distant past but we certainly haven't interacted.
A new technique for measuring the mass of galaxies has been applied to our closest galactic neighbour - and it has found that the Andromeda galaxy is roughly the same size as the Milky Way, and not two to three times bigger as was previously thought.
So basically the milky way is in heat, and andromeda is trying to mate with the milky way to form new stars and other masses. Lol The ultimate circle of life!
I think the halo is the remnant of a prior galactic collision. The lightest atoms and molecules are the last to be corralled into the host. Also, I think the Milky Way is still a bit misshapen from a prior collision of its own.
1 million years, I think, was original timeline. However, galaxies are bigger than previously thought. Our solar system extends way further than we know about, our galaxy is way bigger, and every galaxy has a super massive blackhole at its center. This could be the engine for a celestial event of unidentified magnitude. Do we pass like ghosts or are we torn apart by gravity?
So how close would Andromeda Galaxy have to be to study it and get back at light speed, then how much time would be left before Andromeda Galaxy would boomerang around the milkyway and come back to collide.
I believe it has actually arrived here. Yesterday when I striked a match the air around it got ignited and made a loud boom. Yeah, it must have been Andromeda hydrogen!!
No. They collide when their galactic disks collide; not when loosely associated ultra-low density, Alpha particles (ionized hydrogen) reach us. An analogy would be a saying you've collided with a bum on the street with horrible BO because you were close enough to smell him - but you never actually physically contacted him.
I've read that the milky way has almost twice the mass of Andromeda, if this is true... The milky way is consuming Andromeda. Just because it has more stars does not mean anything.
★ Cuddlepuff ★ We don't even closely know if we are the only life containing planet in our galaxy. We haven't observed "a lot" (near to nothing in relation) outside our solar system
Could the overly large halo be the result of a past collision or close encounter with another galaxy? Gravitational perturbations can cause new star formation in galaxies, can they also trigger large numbers of super-novas? I know those are very different events, but as a lay person, I wonder if that might explain the larger than usual halo around Andromeda
before i finish watching this, I'm at the part where he's talking about the ionized hydrogen... is this going to be like, we're seeing hydrogen particles pass through the milky way that are travelling the same speed that the andromeda galaxy is to us relatively?
Did the researchers report anything about the density of Andromeda's halo? Are we talking about one hydrogen atom per cubic meter or per cubic kilometer?
Andromeda and the Milkyway are supposed to be two of the largest and oldest galaxy's in the known universe, but what is there relative size to all the other galaxy's?
Would people PLEASE stop commenting things that assume scientists don't account for the speed of light. It's ridiculous, the speed of light is an extremely basic fact you have to account for in space science, they wouldn't just forget to account for it.
Does this discovery only mean that the seeds to andromeda was already massivly big when the Universe was young thus not relesing its supernova stutf into interstellar space ? but keeping it close or is this also a explanation that Milky Way and Andomeda always has been alone in our part of the glactic arm ?
So is this a potential solve for the existence of dark matter? Simply just ionized hydrogen? I mean it's nearly half the mass of andromeda! That'd make a ton of sense to me!
He said the distance between the two galaxies are 2.5 million light years from each other. It means that even if speed of them moving towards each other is zero, the expanse of both galaxies (including the halos) is 2.5 million light years big as they are touching already or the halos are merging . So, at what speed are they moving towards each other - perhaps 2.5 million light years divided by 4 billion years. I do not get the speed? Anyone?
If you are basing the distance of Andromeda and the Milky Way by telescopes. You have to factor in that the light that reaches us has already have been long since dulled. Millions of years has since passed since the flickers we see in the night sky has passed. So recalculate, Andromeda is much closer than we think it is, space time is tricky. For every day to us on earth has passed, in the night sky. Millions if not billions of years are what we are seeing in the night sky. So when you think on it. When you look up to the heavens in the night sky, you are in fact seeing living historical events that has taken place way before Humans ever thought of creating fire to heat themselves.
For over 20 yrs now we have had SPACE TELESCOPES floating a couple hundred miles above us out of atmosphere. Those Sightings and photos are a bit Overwhelming. And distance can be counted more accurately.
And now we have mass hysteria I’ll Grab my lawn chair and watch it come in then I could say I seen something in my life. I like your videos always interesting.
The milky way is a dense gallaxy . Two andromada galaxies cramed into just 125,000 light years is very dence. So tue , milky way problably will sirvive the collision
This is a pedantic topic. If we define the limits of galaxies as everything gravitationally bound to them, then it's not surprising that stuff is bound to one or the other as opposed to getting stuck in the middle.
I thought the "actual" galaxys are elready colliding 😅 That would be scary... i know, the chance stars will collide would be very very very small, its enough to get a star near us to cook us D: So we could only hope we wouldn't get cooked XD Also good video! :D
Isn't Andromeda the product of an earlier collision with another galaxy?? It has two nuclei, I believe Chandra has several several good 'pictures'. Would definately explain the increased supernovas and excess space debris. Thanks from Detroit.
If both the galaxies have similar halo, that is already interacting, and will be doing so increasingly as we close the distance, might we expect some accumulation of denser areas and new star formation between the galaxies, in the halo area?
Perhaps even a new galaxy emerge? The Milky Way and Andromeda would literally have a baby Galaxy together. Perhaps... it could be called "Milkdromeda" ?
Wait, so if the galaxies are 2.5 million light years apart and they are set to collide in ~4 billion years, doesn't that mean their closing velocity is in the neighborhood of 0.06% the speed of light?!! That's really really fast.
If Andromeda's supermassive black hole experienced an active phase in the past and created massive jets that would have deposited a lot of material in the halo too, I guess.
I don't think that they already collided, although the light from both galaxies is taking a very long time to reach Earth, but I think the galaxies are still separated.
So for humanity to survive we'll have to not only move beyond our solar system and escape the Milky Way (thought impossible?) but we will also have to survive a giant collision of galaxies? Is it possible to escape a galaxy if you are stuff from a supernova. We should aim towards becoming that then. By the way, is it possible to say that the galaxies are having sex?
So if Andromeda is around 2.5 million lightyears distant, but the colision will happen about 4 million years from now, are you telling us that the Andromeda galaxy is just cruising along at .5c?
So... TEEEEEECHNICALLY the andromeda galaxy and the Milky Way galaxy does not exist anymore or if they do then at point do we consider them both to be the same galaxy?
"Recently the amount of galaxies in the universe, and the Milky Way galaxy size/star was revised. The known universe quantity of galaxies was upped 200%, because the space borne sensors were upgraded. Same for the Milky Way, 150 kly across, instead of 100 kly. Also the MW star quantity was way low. So this is indicative of astronomy and astrophysics." "I calculate

Aside from minor human scteffEfforts by particle science, and super conduction allowing for quark gluon scinotorPlasma, dark antiMatter, through early faster-than-light emiTravel experiments that lead to later Star travels.
Wouldn't it be safe to say that the milky way also has a large Halo of gas around it? But we are too close to see it. We see right through it without a problem.
It’s funny, no body knows for certain. Somebody chart both galaxies? No, for that we have to wait like 100 years or more for interstellar travels. Billion years and you worrying for that? That’s mental!
When I was a kid, 60+ years ago, I had a science book for children that had an illustration of two galaxies passing through one another. It explained that there was so much distance between stars that the two galaxies would pass through one another with no effect.

Just realised it get ripped apart... Not trying to be a 2 shed guy but aldo got the dw they just glide thru eachother and combined story
the two galaxies would pass through one another but they get closer again and each encounter they get more and more deranged until they merge.
The stars don't get hurt so what's the problem? The dish shape is kind of nice, but I don't see what the big deal is. Life would go on untouched. Think of it as a great many friends arriving. Besides, after another eight billion years it will have a sexy shape again.
The further we are into the future the grimmer it is
Since Andromeda means ruler of men, and via lactia means, like milk road or something, I suggest the Greek word for milkman: Galatas.
Very cool idea!
As long as it's not Galactus

That almost sounds awesome lol most people won't know but it sounds almost like Galaxy 😂

The milky way is a dense gallaxy . Two andromada galaxies cramed into just 125,000 light years is very dence. So tue , milky way problably will sirvive the collision
WHAT YOU CAN SEE IT? where do you look? 👀 👀 👀
At the sky.
This is a pedantic topic. If we define the limits of galaxies as everything gravitationally bound to them, then it's not surprising that stuff is bound to one or the other as opposed to getting stuck in the middle.
Love your vids anton
I thought the "actual" galaxys are elready colliding 😅 That would be scary... i know, the chance stars will collide would be very very very small, its enough to get a star near us to cook us D: So we could only hope we wouldn't get cooked XD Also good video! :D
By the time the galaxies collide (in several billion years) we will already be cooked by our own sun.
Isn't Andromeda the product of an earlier collision with another galaxy?? It has two nuclei, I believe Chandra has several several good 'pictures'. Would definately explain the increased supernovas and excess space debris. Thanks from Detroit.
But I live in The Netherlands, near the center piece.
Can I see *Andromeda Galaxy?*
Juonath yes I believe you can see it if you live in the norther hemisphere of earth.
@@travisjames2350 wrong
You can only see it from the southern hemisphere
You can't see it from up here
Yes you can... You can see it from both hemispheres when it rises and sets.
Though you will have a better view from the north hemisphere.
With the amount of light pollution that area generally has I’m not sure you could
If both the galaxies have similar halo, that is already interacting, and will be doing so increasingly as we close the distance, might we expect some accumulation of denser areas and new star formation between the galaxies, in the halo area?
Perhaps even a new galaxy emerge? The Milky Way and Andromeda would literally have a baby Galaxy together. Perhaps... it could be called "Milkdromeda" ?
Well, if they are already colliding, let's hope no planets collide with the Solar System objects or else the system may be a "little" chaotic.
Bring it Andrómeda ... You son of bitch ....
Wait, so if the galaxies are 2.5 million light years apart and they are set to collide in ~4 billion years, doesn't that mean their closing velocity is in the neighborhood of 0.06% the speed of light?!! That's really really fast.
If Andromeda's supermassive black hole experienced an active phase in the past and created massive jets that would have deposited a lot of material in the halo too, I guess.
They should call the new galaxy Hershey's Kiss. XD
Brilliant
I don't think that they already collided, although the light from both galaxies is taking a very long time to reach Earth, but I think the galaxies are still separated.
As always thank you friend.
Very interesting. Thank you for putting this up.
So for humanity to survive we'll have to not only move beyond our solar system and escape the Milky Way (thought impossible?) but we will also have to survive a giant collision of galaxies? Is it possible to escape a galaxy if you are stuff from a supernova. We should aim towards becoming that then. By the way, is it possible to say that the galaxies are having sex?
Will it be a direct hit or a glancing blow. The angle of their trajectories would be useful to know.
I wonder what the people in the ANdromeda galaxy call our galaxy. I'll bet it is way cooler than "The Milky Way".
So if Andromeda is around 2.5 million lightyears distant, but the colision will happen about 4 million years from now, are you telling us that the Andromeda galaxy is just cruising along at .5c?
So... TEEEEEECHNICALLY the andromeda galaxy and the Milky Way galaxy does not exist anymore or if they do then at point do we consider them both to be the same galaxy?
"Recently the amount of galaxies in the universe, and the Milky Way galaxy size/star was revised. The known universe quantity of galaxies was upped 200%, because the space borne sensors were upgraded. Same for the Milky Way, 150 kly across, instead of 100 kly. Also the MW star quantity was way low. So this is indicative of astronomy and astrophysics."
"I calculate
We still don't know how big is both the galaxies are. Andromeda too might be bigger than 220000 ly
Does a Ford Galaxy have a halo too? The 1972 model sure does!
Hey man, i really like what yo do
Does this factor in the new evidence that the milky way is approximately 4x bigger than we had previously thought?
Nice. Yes, the multiverse-exposing Macro Butterfly Effects, the alednaMirror Effect in the rajoMacro, are al+ready being scene.
Aside from minor human scteffEfforts by particle science, and super conduction allowing for quark gluon scinotorPlasma, dark antiMatter, through early faster-than-light emiTravel experiments that lead to later Star travels.
Wouldn't it be safe to say that the milky way also has a large Halo of gas around it? But we are too close to see it. We see right through it without a problem.
155 people are Andromedean.
It’s funny, no body knows for certain. Somebody chart both galaxies? No, for that we have to wait like 100 years or more for interstellar travels. Billion years and you worrying for that? That’s mental!
Anton, what is this galaxy that keeps cloning itself? Is this a real thing? If so, how is this not breaking physics as we know it?
Will some of either galaxy be taken by the black holes in the center of each
WHy would the 'halo' around the Andromeda galaxy be spherical instead of lateral?
because that's how dark matter works.
When u realised both of em lives in a galaxy 👁️👄👁️
What software are you using for the simulation? I'll appreciate very much if u give me the name of it. Thanks, really interesting video 👍🏻
Eddy Zahu universe sandbox squared
He uses universe sandbox 2
Are there any liveable planets in the other arms of our galaxy?
