Universe Sandbox 2 - Galactic Collision - Will Sun Survive? 

Antons voice sounded so different back then. His accent sounds different as well.

WHY DON'T WE JUST TAKE THE GALAXY, AND MOVE IT SOMEWHERE ELSE!

dat black hole on 13:45 made a dwarf galaxy

The two supermassive blackholes at the center of the galaxy will collide into one mega duper super mega blackhole

I have been learning about space in school and it interests me a lot! IT is just so beautiful!

Why did your voice changed a little

its nice to watch these sandbox videos with someone who actually knows a little something about space and physics

You earned a new subscriber.You have great videos, vast knowledge about space and you know really well how to use Universe sandbox to make educational videos with a entertaining flavor to it. Keep up the good work!

Andromeda + Milky way = Milkdromeda

When I'm dead I'm so gonna watch the Galaxy's collide in Heaven.

Milky Way:Hi, Andromeda Andromeda:Hi Milky Way:wanna go on a. . . Andromeda:date? Milky Way:Y-yes *blushes* Andromeda: *kisses Milky Way* 1 year later... Andromeda:I think I have a baby... Milky Way:WHAT?!?! Andromeda: *has a baby (collision)* Makes a baby called Milkdromeda

We need to build a wall to stop Andromeda!

I think when the sun will expand we won't even be on earth anymore

Andromeda Way 😂😂

Watching this in 2018.. your voice has deepened alot.

It's very, very unlikely that the aftermath of the Milky Way - Andromeda collision will result in the new galaxy being such a beautiful disk like the one you got at the end. The result will most likely be an elliptical galaxy, like the first few you did. As they collide, they fling stars and gas everywhere and lots of stars are born in a short amount of time, and then they are flung around everywhere. Lots of supernovas are happening because lots of massive stars that die young are being made, and overall you have mass chaos. In the end, the disks are destroyed and their stars scattered absolutely everywhere, and you end up with a kind of ellipsoid like what you see here: upload.wikimedia.org/wikipedia/commons/thumb/d/d3/Abell_S740%2C_cropped_to_ESO_325-G004.jpg/1200px-Abell_S740%2C_cropped_to_ESO_325-G004.jpg But yes, it is super unlikely that the sun will collide with anything. Life on Earth could be threatened in a number of ways though. First, the Sun might get flung towards the center of the galaxy where there is too much ultraviolet radiation for life on Earth to be comfortable. Second, a passing star, while unlikely to collide with the sun, is still very likely to disrupt Oort cloud objects and cause a bombardment of comets throughout the solar system. Third, there will be a lot of star formation happening, and some of those stars will be very massive and become supernovas withing a few million years, so there is a high probability of a supernova in the danger zone. The best outcome for the Earth would for the sun to be flung into the outer reaches of the new galaxy where things are relatively calm. Plus, imagine the view if we got flung from the galaxy. Life on Earth would be fine if it were flung from the galaxy since the Sun is the source of heat for it, and as long as it is still there, Earth will be fine far away from the galactic center, although it would make interstellar travel a pain (granted, we will probably have that long figured out by then).

it was like two byeblade collision 💥

thanks for answering my questions

I like that while they are colliding millions of years are passing. Mind = blown

"Our galaxies will combine" it's called having sex. And the baby name is milkdromeda.

Can you help me? For some reason I can't zoom out far enough to view a galaxy and everytime I spawn one I insta lag inside of it xD

Anton you deserve 100.000 Subs

havent watched this fully but I'd expect with the size of a galaxy the mathematical probably of a collision is so astronomical

WHY DON'T WE TAKE OUR GALAXY, AND PUSH IT SOMEWHERE ELSE

I enjoy this guys stuff

I'm an astronomical nut & your series is much appreciated … thank you … !

Just saying our closest star is Proxima Centauri A or Alpha Centauri C , Alpha Centauri is a system - containing 3 stars and 1 planet called Proxima Centauri B which is in the Goldilox zone so may be capable to host life.

HI LUV UR VIDS!!!

Your Twitter link is your Twitch link and your Twitch link is your Twitter link! XD

Actually it is most likely the two galaxies combine into 1. So there will be no dominant blackhole, they're both gonna combine so either way. Both galaxies will not be the same.

So in heaven we wait a while and we watch this.

wow!!! we have ancestors in the future!?!? (sarcasm. btw)

the galaxy will not probably still not be called andromeda it will be like milkdromeda or something else

We might not depend on our black hole... But if we're ever to survive our star we'll have to be able to actually *leave* it... And that'll be hard if *it* leaves behind pretty much every likely candidate of colonization back in the new galaxy as it flies out into space... Basically the long term survival of human kind *depends* on being within a galaxy with fresh stars and planets where we can move once our old ones (including whatever we go to after Sol) dies.

Mass stays the same. Density stays the same. Radius increases. >DOES NOT COMPUTE

Is this Galaxy S8 or S7?

So basically we have 3.5b years to figure out wormholes or we die

And then molecules will reform, creating new beings, leaving us behind. I wonder how much time it will take them to find out they were born of our dust and ashes.

@Anton, you made an error (time 11:33) when computing the Andromeda black hole mass - instead of making it 23 times bigger, you made it 2.3 times bigger, should add an extra zero there.

Guys, come on. There is no 'battle'. No galaxy will 'win'. You're thinking of this in primitive human terms. The black holes will simply merge, becoming more massive, and new galaxy will simply have the stars of both Andromeda and the Milky Way. Almost none of the stars will physically 'collide'. You KNOW how much space there is between stars, right?

Everyone run were dead

Eight years later, and this pops up for recommended

Chances are that not 1 star would collide due to the vast distances between stars in comparison to their size.

The nearest star to us is actually Promixa Centauri.(:

15:37 Milky way and Andromeda way are kissing

Before that happens, Sun will turn into red giant and swallow earth.

I watch you videos just to got to sleep

Hopefully our ancestors survive the future? Ummm I might not be the smart guy or have hear the definition of ancestors wrong but isnt that supposed to mean your past generation or am I wrong and it accounts for the future generation too?

We'll be living on planet Anton XD

Milkomedra will be amazing because it will have 3 cores in the center :D (yes, andromeda was formed by 2 tiny galaxies fusing. that should explain the two cores.)

Your what da math intro is creepy at night sometimes

HE SOUNDS SO YOUNG!

WHAT HAPPENED TO YOUR VOICE?!

Best intro 2017

I hoped I would see our sun's perspective in all of this

Amazing vid +1Sub

Sun won't become nova. Nova is happening with white dwarf. It may be called smaller type 1a supernova. But type 1a supernova destroys the white dwarf completely. Nova is just ignition of accumulated plasma on a surface of the white dwarf from other star. So it happens with binary stars. One is normal sequenced star or red giant and the other is white dwarf. White dwarf is sucking plasma from the other star on its surface. As more and more plasma is accumulating on white dwarf, the pressure of lower layer of this matter increases and thus the temperature as well and nuclear fusion starts. As the pressure and temperature increases even more, another nuclear fusion starts, during which the brightness of the white dwarf increases rapidly and drastically. And that is called Nova. It's not even an explosion and the white dwarf usually survives this event. Our Sun will just burn out hydrogen, the core will start shrinking and will increase pressure and temperature due to that and will start heating up the layers above the core, where is still hydrogen left. The fusion of these layers will start and since this fusion is much faster and much hotter, the brightness increases a lot, which causes the upper layers to expand. After this fusion stops, the layers above core will shrink and start to make pressure on the core. This pressure will make brightness high enough to blow away the upper layers of the Sun and creating nebula and white dwarf is left in the center. As for merging Milky way with Andromeda, there is not really high chance that Sun will crash into something during this event.

its so weird not hearing "hello wonderful people" at the beginning of one of your videos.

I can watch that part where they collide so many time IT'S SO INTERESTING TOO ME!!!

In my opinion the stars will collide with a much higher chance... with all those unpredictable changes of gravitational fields...

Stop worrying about the collision thing, We'll be dead when it happens.

It's low chance, but orbit will be change, everything hard to guess, right?

So, in billions of years, the two galaxies will combine and become the Andromeda Milkyway Galaxy.

Fuck andromeda we should be worried about the M21 and M23

#TeamMilkyWay!😃😃😃😃 #FuckAndromedaLoser!!!😠😠😠

Nice math what da math✖️➕➖➗💲👍

Watching back on these older videos is so weird. Your voice is so different:o

I learn more here than in school

Anton sounds soooo young in this! Hahaha

And this, people, is gonna be called the Super-Galaxy, 'Melomedies'

Eeeh... It seems more likely that most stars and most things will go through the galaxy merger without much effect. I mean, globular clusters might be highly disrupted, but stars, especially "lonely" ones like our Sun, will probably go completely unaffected. Space is big. Really big... and there's a LOT of space around us.

I have a idea ,Make in the next Video a solar system with the Planets of Star Wars (Tatooine,and other Planets of Star Wars Universe :)

Anton, I hate to disagree, but according to every astrophysicist I ever talked to, the chance of our sun directly hitting another star is about 1 in 1 billion, & more likely, they would alter each other's course to due to gravitational effects. Also, once the galaxies combine, the suggested shape will be more of a flattened egg than anything.

For those wondering, The Sun will be also going through its Red Giant phase as well and will pretty much be a White Dwarf before the Milkdromeda even finishes forming. The Inner Planets will have been throughly roasted, so we won't have to worry.

supernovas in that coliding galaxy are most likely produced by massive stars born out of colliding coulds of gas from both galaxies

Congrats on5k subs!

@Anton Petrov The question is; what happens to the planets? What is the chance, they get kicked out?

I like this.

The sun will do whats officially called a "type a" or "type 1" supernova. where it kind of falls in on itself, then like a rain drop hitting a pond, it kind of re-splashes back out from that collapse and all but the core will blow itself away. a "Type B" or "Type 2" supernova on the other hand, THAT is the big "Ka-BEEWWWWMMMMM" we all know and love

Our sun is going to be fine my guy, the two black holes are on a collision course, our sun isn’t on one with anything

Amazing...

Big bang would create

When/if this happens... Worrying about hitting another star will be the least of our problems.. in the miniscule chance that our solar system exists after this.. well be lucky to not be sent rouge through space or into either of the blackholes

the fores of the other glexey would make us start going into space if we were alive

Wow ur voice is really nice better then mines

O GAWD I FOUND A BETTER WAY TO MAKE A BIG BANG:1. Make a Supernova2. Select all the Nebula and click on Edit Mode3. Do the same thing in this video4. You created a young universe

Doesn't really matter because by then the Sun will be reaching the end of its main sequence, making it so hot that the Earth will boil.

Its crazy how long it takes

Our entire solar system got flinged

I thought that I'm th only one noticed Anton's changed voice. My tab is minimized and just listening that I thought that anothr youtuber is doing his video. LOL

The Milky Way Galaxy is not gonna be Gone........ The Galaxy Name is gonna be Milkdromenda

5.5 or 4.4, which is it? And from today meaning like at midnight? What time zone are we using? I have a couple of questions about the exact timing of this Galactic Collision

Cool that there are no star collisions, what about the endless stars that will get swallowed up by the black holes?

Andomeda just had to come and kill possibly the only life in our galxy or universe

can you make a vid on when our 2 galaxies collide and id like to see if the Black Hole try to make a complete single galaxy or it could just eat the whole galaxy and id like to see what the maximum time speed.

Andromeda is Greek for "mindful of her man" and Via Lactea is Latin for "milky way". I propose the name for the new galaxy should be Galatas, Greek for "milkman".

"Stars will collapse to each other" - Most probably they wont. Even though the galaxies themselves will collide, the distance between the starts and the other elements found in a galaxy is so big, they probably wont even come close to each other. Correct me if im wrong though. Im just watching youtube, in not a scientist.

ആരാണീ വിചിത്ര ചിത്രകലാകാരൻ ഇത്ര മനോഹരമീ ലോകത്തെ അണിയിച്ചൊര ചിത്രകലാ കാരനാരാ തിരയുന്നു നിന്നെ അണവിലും അണുവായ ഞാൻ

The stars in the two galaxies are numerous and widely vary in size, however, the distance between the stars is far greater. The math says the chances of one star hitting another is virtually 0. When this takes place the galaxies will pass through each other a few time as the supermassive black holes go into a dance go back and forth and then merging into one larger supermassive black hole. Stars will be victims of this dance and some will be ejected out of the collision and will wander the voids between the galaxies. As all this happens the gasses in the galaxies will heat up collide and collapse that can create a starburst. When that happens if we happen to still be here they sky will look like it is on fire. The starburst will creat a massive amount of new star formation. This is a spectacular event and would be incredible to see. In the end both galaxies structures will be destroyed forming a new elliptical galaxy, no spiral arms, and Milkomeda will be born.

Hey when you were doing your earliest videos, were'nt you into health and stuff before you got into astronomy?
