- About 4.5 billion years from now, the Milky Way will collide with the Andromeda galaxy. This epic collision will lead to the formation of a new elliptical galaxy often nicknamed Milkomeda or Milkdromeda. But this won't be the first collision of our galaxy. Our galaxy is a monster that has crossed paths with and destroyed several galaxies in the past. But how do we know that it had a violent history? Where are those galaxies that once crossed paths with our galaxy? And most importantly, how did those collisions affect the evolution and the shape of the Milky Way?
The ninth episode of the Sunday Discoveries Series is about the research on Milky Way's past collisions with other galaxies. Astronomers have made two major discoveries related to the past collisions of the Milky Way. All the references can be found below:

Since the collision of the milky way and andromeda will be such a slow event there is no point in time that you could travel to to watch it happen. You could only travel to a point to see what our sky looks like after the merger. So the supernova of Betelgeuse would be my destination.
You really are an indoctrinated mess
I'm really curious just of what the progression of humanity is.
@@PoochieCollins I'm really just curious as to why you believe this horse shit
@@PoochieCollins humans turn to computer.
Any free rides?
I'm setting my alarm for this one!
I was just waiting for this video!! Another great video of Sunday Discovery series!
Yay, thank you! Hope you enjoyed it :)
@@TheSecretsoftheUniverse Enjoyed a lot :)
"our galaxy is a monster that has crossed paths with, and destroyed several galaxies in the past" How can they be so sure "our galaxy" is not one of the ones destroyed instead of the one destroying?
I mean, for all we know our star and the planets in our solar system could have been part of one of the galaxies that merged with the milky way.
Probably because of our and our kin's trajectory. I mean, we can almost study the effects first hand by looking elsewhere...
@Chris correct about what?
He's asking a question and then leaving an open ended alternative.
As for that there may be an alternative, it makes no sense for you to bombastically claim that _that_ is the correct empirical event.
Not to mention I don't think so.
Pardon me if I misunderstood.
Hmmm. I suppose the smaller one merges with the bigger one?
Shape of the galaxy? Worth buying a book so you can read and reread and then buy anither book that proposes a different solution. There isnt enough time in these short videos.
Or, since you have an enquiring mind and feel up to it study astronomy.
@@helenamcginty4920 I'm 32 years old, already have a career and I look at things like this out of curiosity and for entertainment. I'm just asking if there's a possibility that our star and planet could have belonged long ago to a minor galaxy that collided with the Milky Way. Either way, I will take your advise and I will read a few books and maybe even buy a telescope. Thanks, I hope for you to have a lovely weekend.
I thought this, too. I don't think anything is being destroyed, or am I wrong? I'm not a scientist
Was waiting for it.......
I'd like to see the birth of Milkdromeda 🤩

I always learn so much from these videos...so interesting and educational.
if we can see all that i am sure we can see what is on the surface of planets.
Except how to properly pronounce metallicity.😬🤣
@@Gointothelight yeah, I'm looking at the surface of a planet right now. It's below my feet
@@krumuvecis me too
I, really, from deep down of my heart..want to witness this galactic collision of milky way and andromeda
Unfortunately, it will happen very slowly from our perspective
We are talking about a slow death……real slow. 👍👍👍
Whoa... Thank you for the video that answered my curiosity for Years
You’re welcome 😇
@@TheSecretsoftheUniverse I recently read an article where it said Andromeda collision already started where the dark matter boundaries of both galaxies are already collision.
@@Arivarul Yes! The 4.5 billion-year time frame refers to the first encounter of the galaxies' stars. Andromeda and the Milky Way will take more than two billion years to merge completely. Galaxy mergers are long events, and many large scale processes are involved: tidal forces forming stellar streams and nuclei mergers being the most prominent ones.
Wait till the bacon and pancakes galaxy merges as well 😋
LOL
😂😂
Why does this not have more likes 🤣🤣
I will bring the syrup (is maple o.k.?)
Omg
A “really fast” collision could take millions, billions of years. A slow one could take a eternity. Can you imagine being in a car wreck that lasts 100 years…….😳😳😳
"Look out! Look out! I'm gonna crash my slow-mobile! I had to swerve to avoid you."
It's not the same. Time is relative, remember. What is a 100-year car crash if you live for let's say 10 billion years. 100 years can be very fast for you then. What feels slow or fast for us doesn't have to feel the same for another creature/being/whatever.
@@dtd6061 But I don’t live that long and I am only human……
Great video, and excellent effects; I was left wondering why there was no mention of the SMBH at the centre of our galaxy, and what role it played throughout.
Our descendants who will represent us as human beings, I would well imagine them to really like to visualise and experience the formation of MIlkomeda, and I pray to God Almighty to keep them safe and sound in whichever solar system they are in that period. They can then relate amongst themselves how their ancestors on Earth had foreseen the massive merger almost 4.5 billion years ago !!!
@@ayudhdasroy7090 just one small thing, you need to reread what he wrote. Actually he’s saying people in the future who get to see this event will look back at us and say people on Earth predicted this would happen 4.5 billion years ago.
@@ayudhdasroy7090 just trying to help you out.
reading/paying attention > being smug/trying to prove you’re more intelligent than someone else.
@@ayudhdasroy7090 sure.
Long before the merger happens, our Sun will have expanded out to Mars and everything here will be plasma. If we ever get off this rock of ours, the journey to a new planet will have taken so long that no history of our ancestors will exist and we will not know where we came from. If we ever evolve beyond the idea of a god, future theories on our origins will make great conversation. However it's quite likely that our entire race will just cease to exist and the existence of Earth will be unrecorded.
Earth won't be here you wacker🤣
And even if another civilization of man arose they still wouldn't even know about us or a place we called Earth.
With all the collisions, I guess there's a chance our solar system was originally from another galaxy.
AHAHAHAHA...oh wait...hold on...AHAHAHAHA AHAHAHAHA AHAHAHAHA AHAHAHAHA AHAHAHAHA AHAHAHAHA AHAHAHAHA AHAHAHAHA AHAHAHAHA AHAHAHAHA
No not really. The Solar System's original dust cloud came from the Milky Way - most likely not from another galaxy as the Sun's only been around for about 5 billion years so far. The dust that made up the cloud that condensed into the Sun, and then into the rest of the Solar System, might contain substance from some of the collided galaxies, but it was still ultimately made here in the Orion Arm of the Milky Way.
Or the ingredients for our solar system are a combination of two galaxies, it could have formed after a collision and may never have formed without the collision?
@@DunkinBiscuits The ONLY ingredients here are a mixture of CGI, pie charts & Sheeple 🤦♂️
@@davidsheckler8417 Damn dude you have a very little very simple mind, never mind
I would like to see the recollapse of the entire universe after all the energy is used up in equilibrium.
When all the matter becomes equal and under its own mass and pull with no more energy collapse rapidly down to a single point to restart the big bang all over again.
Bad news... expansion of space seems to be accelerating - it might never recollapse
Absolutely amazing video.
Quick question for anyone who knows:
For all I know of stars and galaxies, I’ve never really paid much attention to nomenclature. Don’t get me wrong, I’m always interested in why objects are named as they are but thought no more of it than that.
My question is; Sagittarius is both the name of the Sagittarius Dwarf Galaxy (and the subsequent Sagittarius Stream) and Sagittarius A*, our black hole. Both objects are independent of each other so why do they both have the same name?
Were they at one point thought linked?
Or is the suggestion that the black hole came from the Sagittarius Dwarf Galaxy?
They appear in the neighborhood of the constellation of the same name
@@danielallington5152
Thank you
I had kinda assumed that initially but thought that, with the Dwarf Galaxy becoming the Stream and being stretched as it was, it’d cover a larger area and pinning it down to just Sagittarius due to position wouldn’t be accurate.
Thanks again
There aren't any galaxies
@@davidsheckler8417 How do you know this? What was the error that Hubble, all his colleagues, and all subsequent astronomers, who presumably know more about this than you do, made?
Amazing video! I wish I can witness Betelgeuse supernova.
You might...
I would choose to watch whatever way things happen.... So much to understand the universe and beyond
if ya think about the galactic bubble, and if all galaxies have a galactic bubble, the milky way and andromeda are already in the process of collision.
Astronomers already agree that our outer limits of both are already colliding….
Milky Way Galaxy is the best Galaxy! Andromeda can suck it!
In the eyes of humans it will be. It's like someone saying their country is the best
@@nihongotheo4808 Bruh, don't be hating on the Way, mm'kay? Milky Way Galaxy is the best Galaxy! Screw Galactic foreigners and their third galaxy systems! They need to keep their damn dirty foreign galaxy hands off our cows and rednecks!
🔥💯🔥
Easy tiger! :)
Andromeda died after Mass Effect. :p
the Answer to The Last Question - I. Asimov
btw, the new galaxy that forms when Andromeda and the Milky Way combine, it's called The Colab Galaxy it's what causes the Virgo Supercluster to collapse into a single Ultra Quasar
Thank you 👍
Thank you! My whole life I was living in fear we never figure this out.
rest in peace
So I think that this could pose a very interesting question! What are the odds that our solar system actually originated in the milkyway and not one of the various galaxies that have been absorbed? It really doesn't mean anything in the end but it seems to me that it's entirely possible and would be interested to know if it's even possible to even determine something like that.
Does it even make sense to distinguish which one was the "original" galaxy when they merge on a collision?
@@MD-vs9ff it does if there is a way of distinguishing which stars came from which original galaxy. If there is a way to do so then by identifying them there may be questions that arise that we wouldn't ask without the data. In the end, for you and I it most likely wouldn't really mean anything. But asking questions is actually the entire point of science. If we don't ask ourselves the unasked questions then who will?
@@robertlane6431 "But asking questions is actually the entire point of science. If we don't ask ourselves the unasked questions then who will?"
Great!
This idea of yours seemed significant to me. Even my mind wants to believe that this thought is going in the right direction. If you consider the position of our solar system in the Milky Way galaxy, it would not be unreasonable to think so because scientists say that our Milky Way galaxy has collided with other galaxies more than once over billions of years.
Well we run universe simulations forward abs backwards on computers . The more data we get we can simulate backwards better . Maybe one day we will know answer and find earth on the moon or something
Misconception: people think that the black hole at the center of our galaxy holds all the matter together like the solar system
Thank you, very much🤗💫🌞💫
You're welcome :)
Thank you
Amazing
Just amazing what these astronomers have deducted and established as fact in only the past few decades since the Hubble telescope was created and gave us this new account on so many things previously unknown to man. Although our earth most likely be nothing but a baren husk, if even that it will be in existence -- our human atoms, and molecules will still exist in some form and will be a part of this newly constructed galaxy. No telling where our soul will be--if you believe in that concept of immortality.
It's hard for us humans to believe that we really don't matter. That we are just one of the countless organisms that exist once and vanish forever. That our human drama actually means nothing at all. And even worse, that there is no supreme protector who cares for our individual destinies. We are just grains of sand on a beach. It's something our minds are incapable of understanding.
Don't mention soul,your neighbor scientist can have soul sucking heart attack
Facts / theories these are not synonymous words.
@@spidaman0112 they're to lab rats bro,in this modern science aka psuedo narrow minded science we don't have theories proving other theories wrong,but facts going against facts and this continues forever like a loop without realizing loop is itself a huge loophole and all so called facts devastating other so called facts and universally accepted crap is bunch of bull made up on black board or through a lens
Albert Porte is great example and tells us how this psuedo science works,only one Imam Ahmad Raza from bareilly UP of India stood against him and proved him wrong rest of world i.e so called psuedo scientists just had surrendered and were waiting for doomsday lol
If something is theory why are they taught in schools to a child like they're real facts like stationary sun back in the day to Newton's gravity theory itself,this is all indoctrination nothing else just force feeding of crap botched up science
@@bhatbasit8614 I agree.
Really astonishing as to how the astro-scientists have deduced so much about the Universe in so little time relatively. I am confident that mankind development magnitude in the next millions of years will find alternative star and planetary systems for migration from the present solar system.
All this are theories, nothing more. Look like that the XXI century have forgotten what real science is.
Calcultaion made with high error range on an incomplete gravitational understanding on cosmic scale is just a bit more valuable than a science fiction movie.
the next millions years are you listening to yourself, you would not be there to see anything you don't know and either do i
We have to figure out how to stop killing ourselves first.
OR we will all start listening to mumble rap and prioritize working out at the gym, and fighting to get women over intellectual pursuits. Thus never leaving Earth, and going extinct long before the sun goes into its red giant phase.
Intresting topic and great video, thx.
But considering the content, how do we know our solar system originated in the milkyway galaxy? Or the star from which remains our solar system were created?
Many have speculated that much of the solar be system came from Sagittarius Dwarf Spheroidal Galaxy.
I would go 10^100 years into the future and watch huge black holes get really bright and fizzle out as they're overcome by Hawking Radiation.
Would you make a video of Constellation of stars?And how to identify them with naked eye?
there are many already available very good ones. just type in Night Sky Constellations of .... and your home town.
I would like to witness the beginning of time and space. The big bang!!!
The most interesting future event in the life of the Universe will be when matter turns back into pure "consiousness energy".
I would want to travel to the final existence of humans see what happens to us as a species
Haha ….. I think you are already there ! The way things are going, we may be looking at the end of the human race right now.
Packrat is possibly right. I was thinking the exact same thing. We’re already there! Everyone on this planet has gone mad!🤪
I would choose 100 mil years after the big bang event. Gotta be some cool stuff going on.
Does anybody else struggle with the vastness of space? All that deep space. Where does it end? Is there an end? We can't physically see the edge of our own solar system and we know there are so many more out there all floating through what seems an infinite amount of darkness. This were the thoughts that gave me anxiety as a kid haha. Our human thirst for knowledge also creates self induced fears
It gives me such a headache thinking about what's beyond all that
Finally! I've been waiting like half of a light year relative to the earth's rotation to the sun for that. An earth light year.
Light speed isn’t relative
@@drgnyt7487 it certainly is. It's measured in earth time and distance so we can understand it. Miles in a year doesn't translate to anybody but humans on earth. A mile isn't even relative to the metric system. And a year is an earth rotation around the sun. Measurement, itself, is only relative to educated earth humans. Everybody else just has to take their word for it. If they speak the same language.
I would go back in time and see the big bang that happened in 2021!
I would choose to see what happens at the end of the universe, heat death, big crunch/bounce, or if it is truly immortal (if the latter is the case, by default so would I be lol)
It's a gnab gib!
If I could choose, I'd love to witness the Milky Way-Andromeda collision....
I can only imagine what lies beyond there👽
0:27 our galaxy is a monster.. and the monster has such a cute name
I want to see when we collided with the great attractor
Since i was named after the orion constellation. It will be sad that some of our next generations wont be able to witness orion and its beauty. Grantit there will still be rigel and the orion nebula along with the horse head nebula. It just wont be the same without betelguese. But they will have one heck of a show when it does go supernova
Milkdrop Galaxy sounds good
I am going to be greedy and say i would love to see both the Merger as watching Andromeda get closer and closer in the sky would be stunning and also Betelgeuse blow up..... Assuming it hasnt already...... it is what 640 light years away meaning light takes 640 years to get from there to here... for all we know it could have already happened and we are looking at something which in reality no longer exists.... when you think about it....it is wondrous how time takes on a different meaning when compared to space. as you look into the night sky.... your looking at the past not the present...... Although as humans with our eyes.... we cannot see in the future or present we can only see things in the past.... even looking at your hand you are looking at it in the past... as it takes light time to travel from your hand to your eyes... that information to get from your eyes to your brain to then understand it although fast ... it is still in the past..... remarkable when think about it :)
if we can see all that i am sure we can see what is on the surface of planets.
Giant pizza galaxie crunch would be glorious
If I could time travel I would check out the big bang and see what set it off to answer the question once and for all.
The big shrink
assuming the time travel is "you see what it the outside looks like while you do it" I'd go outside the galaxy and watch as Andromeda and the milkway merge into the milkymeda
Id like to see what will happen once the last black hole evaporates
An evolution or object permanance to grow consciousness vertically instead of horizontally would likely have happened in a merge where only up-quarks existed
Alternatively the sun is an artificially condensed red giant
Humanity will be around to witness these galaxy colliding events.
Hi,
I'm wondering about the relative motion of Andromeda and milky way galaxies towards great attractor or Lineakea supercluster. Who is trailing whom. Are both of the galaxies moving towards great attractor, with distance between them dropping due to difference in relative speed!!!
we're slightly ahead
I'd travel to see the last black hole flare up, explode in an amazing last hurrah. As its mass gets too low, due to hawking radiation. Then after the light fades away sit there and contemplate that that is the end of everything.
If I can time travel, I'd want to know the current situation of TON 618
What kinda camera do u use to know this billions lighyears away?
Does anyone know who made the soundtrack?
I prefer to say "we believe" before every statement. As in "we believe this was 8 billion years ago". Nothing is ever set in stone when it comes to knowledge; to put it simply, you can never know what you don't know.
It would be interesting to see what happens if the super huge black holes in the centre of these structures collided head on at a speed of around 10%C. All you would hear is ...... GULP!!! Nothing is forever. Cya! 🇭🇲🤗
Someone needs to get a restraining order against that monster.
Thia tells us that our end can be fast as an Asteroid crash and slow as a galaxy collision
wow. Our milky way a great old man like galaxy, andromeda will be its deathbed, and guarantee we be a elliptical galaxy in the end.
crazy history and many civilizations come and gone each time of event.
the next big bang
Can the remanence of a galaxy with no central nexus still have planets with life as they orbit their star?
Just about anything can be possible
I would think so.
Finally found another cartoon to mesmerize more Sheeple
How bright is the night time of distant future earth if andromeda galaxy merge?
In a much nearer event most likely....it would be Jupiter's next foray into the inner planets orbits....
As in my astronomy college class, this puts me to sleep... 😴 Snore!
The big bang
the event i would travel to is the stagatarius drawf galaxy
I would love to see Betelgeuse go super nova in my lifetime, or any super nova would be amazing.
Hence the two belts of dust and debris in our solar system.
I'm just waiting till Nibiru comes back around.
Milkyway galaxy is the goat..
... I'm confident that Andromeda doesn't stand a chance vs the milky way
So is it possible for our solar system is from another galaxy that collided with the Milky Way?
It is. Or at least, we (and everything else on this planet) are made up from star dust originating from several galaxies.
Galaxy collisions are too much slow, we can't even aware if any merger will happen.
Petition to name all galaxies that collided with the milkyway after various foods, we can't just have the sausage galaxy be grouped together with greek/roman mythology-based galaxies.
when milky way meets andromeda that has way much bigger and stronger blackhole named M87, will rip our galaxy apart
Gamma Ray burst I think that would end us quickly
Would love to be present when we are close enough to the great attractor to find out what the heck it is. I am betting some ultra super mega blackhole but who knows.
Is it possible to travel out of our Milky Way Galaxy to explore other areas in the space.. So that we can may able to find other planets....
Hard to answer what one would theoretically want to see, I mean... in _practice,_ however that would be possible, I would be born into how the sky looks and not notice any difference. So that becomes irrelevant.
Time travel is irrelevant to me because it is physically impossible two times over...
Sooooo I guess neither? But I'd love to see a very well done artistic rendition of it sped up to Michael Bay levels of action lol.
Yeah the theory crafting can be interesting, but we have but a fraction of that time to figure out just to save our species on _this_ planet, let alone colonize elsewhere in _our_ galaxy.
First things first.
And considering we currently have a single person megalomaniac putting our entire species and future at risk and threatening with nuclear war in this day and age if anyone intervenes in their pointless aggression, and we let this happen, then surely none of us deserves to see the future either way.
Just too bad so many bright people are thrown under the bus because we couldn't deal with a small group of insane people. Our grandchildren will be ashamed, but at least not as ashamed as Putinists should be.
Death of Betelgeuse and Sirius-A
8:51 "then over the next 150 BILLION years"

A magnetar neutronstar would be very interesting to observe, but they are so small so no telescope can see them close.
They're not small, they're far away!

How humans think?

In some typical way human thinks.
If humans can find correct form of think,
Humans can discover space more effective.
It will increase the speed of formation of new life on different planets as well as it also invent new technologies.
A question from the US Navy Nuke Power Exam: Define the universe. Give 3 examples.
That isn't true that the LMC will be captured by the milky way and pulled into our galaxy. Many top astrophysicists believe that both the LMC and the SMC are moving far to quickly to be captured by our galaxy and may in fact just move on and out of the plane of the Milky Way. Andromeda, however, is most likely going to merge with our galaxy as you stated.
According to main stream astronomers, our galaxies furthest reaches are already colliding…….
one event to witness? last moments of last star in universe
