Hello, wonderful person this is anton and in today's video. I wanted to explore our [beautiful] star the sun
I wanted to talk about the creation and the destruction or eventual destruction of this beautiful star so that you actually find out
Where what is it actually born?
How was it made and how would actually perish let's find out in this video and welcome to what [the] math?
and
Our story starts something like 5 billion years ago
[ins] in our Galaxy the milky way where a star by the name of whoa. We're just gonna call it huge star
Decided to end its life and go Supernova. [it] was so massive and so large that it basically couldn't handle it anymore and
With time went Supernova that we're going to create right now by changing these parameters right here
now this Supernova started spreading away from the star and the actual star became either a
Black hole or a neutron star that is still somewhere out there in our Galaxy
But what happened to the remains of the star is?
Another story so all this stuff that is coming out from the middle is
Essentially what's going [to] create our sun and many other stars as well?
but that's not everything [as] a
Matter of fact all of this new material that was created from the Supernova is also going to create you and me as a matter
Of fact things like iron for example are only created during Supernovae so Ayran in your blood is
Basically from this huge explosion in other words you're essentially mostly
Stardust that exploded 5 billion years ago, isn't that kind of cool, but anyway, so this didn't last very long and after a few
1000 or possibly a hundred thousand years this will dissipate and become dark star dust and then eventually
Some of the star dust will start clumping into little chunks and little pieces so that's going to be our next stage
Now all the [Supernova] stuff basically kind of possibly looks like this now
I mean it's a little bit more colorful so that it's a little bit easier [to] see but it's
Essentially the dust particles [that] started to coalesce into larger and larger particles and somewhere in the middle
[there's] going to be an even larger chunk
I'm going to call sunny this object is about 1.74 meters in Radius
And it's essentially our tiny little sun, or what will become our tiny little sun
Or I guess large sun that we have today, but it started with this tiny rock now. I'm going to run the simulation here
And possibly increase time so that you can actually see how they're [all] start interacting with one another
combining, what one another and
basically orbit around
The object with the most mass now to make this a little bit more interesting what we're going to do is we're going to hold
all velocities
add
a little bit more dust and just watch it coalesce and basically collide with sun here and
Make it grow in size. It's basically how
With time our sunny our sun our young sun started to acquire more and more mass now
This was the second stage it obviously didn't happen this fast [I]
cheated a little bit
[I'm] [a] this accelerated
But over thousands of years it became bigger and bigger larger and larger and it also had a lot of material
Still orbiting around it
so you're going [to] see what it all looks like when I accelerate time and show you what actually happens near the end and
So here is the beginning of our sun it has a lot of material
Orbiting around it it's [for] with the most massive object in this region, and it starts attracting more and [more]
mass and basically starts creating a larger and larger
object in the middle at some point this will actually become something that looks like basically a planet and
As it acquires more and more mass?
it's going to become more big [attract] [even] more, mass and basically so on and so forth so
everything in the vicinity will start getting attracted to sunny and
Will create a larger and larger and larger object whereas some of the particles will actually just start
orbiting around it and
Create the accretion disk that will later create things like Earth mars venus and of course you and I as well
so let's just see what happens here after a few more [I] guess hours in this case and
in reality this would actually actually take close to a million years a possibly even longer and
So after a million years this is kind of what it looks like
but because it's a lot more massive now it starts attracting even more mass from the outside and
Becomes larger and larger and larger, so let's try to emulate this again
Now I accidentally added chunks that are a little bit too large
But they look absolutely cool and really really colorful
and this is actually what happened all of them got absorbed by by sunny here, and we're going to
decrease velocities and see if I can basically reabsorb all of this stuff again and create a
Really [nice-looking] system with quite a lot of various particles orbiting [um] and here we have particles of different size
that sort of starts looking more and more like the actual
early solar system now
We're going to once again stop the velocity and make it absorbed into sunny just so that it [actually] grows in size and becomes
closer and closer to what seems to be a planet now obviously this continues for Several million years and
Over five to six million years it becomes more and more large and acquires more and more accretion discs
And at some point starts looking kind of like this
There's a lot of material in this particular solar system
But most of it is either a torus or a [ring-like] formation that orbits around the central object named sunny
Now with time of course this will start increasing in size again
Gaining more and more, mass and at some point will basically
combine all of this material into itself you can see it happening right now and
This will take maybe a few more million years until it then becomes. What's known as a gas giant?
Now at this point it reached enough
Mass to actually naturally start growing by itself because even though there are a lot of particles orbiting around it
a lot of them have unstable orbits, and they will always collide with this object and create a lot of craters create a lot of
earthquakes and destruction
[so] obviously this is basically an object has been always
Always bombarded by various particles that are orbiting around it, but we're still not in a gas giant stage
So we're going to increase the mass a little bit more until this becomes a gas giant
Now actually as soon as I change this to hydrogen
It happens almost right away
[and] so there we go
And we know that most of the material inside our sun is actually hydrogen [some] [is] all change it to something like this
this is more realistic here and
So now it's becoming something a little bit more
Like the protosun now at some point this will actually start acquiring enough
Mass to become more and more massive and more and more hot on the inside and this is the period
That we often refer to as the protostar so here
It's actually going to start heating up on the inside and even emitting light. It's going to happen
in a few
Thousand hundreds of thousands of years as it absorbs more and more mass that you see orbiting around it
This is a little bit too. Fast actually I might have to slow it down and so here we go
this is the next stage when we're now going to be creating the protostar and
It would only take a sunny a few million years to essentially become what would be known as a brown dwarf, basically
gas giant that is
kind of glowing
Produces a lot of infrared light, but it's not hot [enough] to be a star [just] yet
but because this will actually increase in size over time and
Will acquire more and more mass it will eventually reach the star status
which is going to happen really really really soon right about now actually and
There we go sunny is now officially the sun
now so that's how it all started a lot of this other stuff then coalesced into
essentially planets became Earth and so on and so forth
But that was all in the past today of course it kind of looks a little bit different
So let's fast-forward to the future and go into
The solar system simulation so that you get to see what it looks like today, but of course this is the present now
Let's go into [the] future. We're going to start
Fast-forwarding this and we're going to try to recreate the future of our sun
So let's go into a few billion years from now and as you can [see] the sun has become a little bit [largerr]
after about two more billionaires
It's going to become just a little bit larger, and then it's going to become a little bit larger
it's luminosity is increasing its producing more and more light and
basically it is slowly burning through hydrogen and increasing its size until
One day, it's going to become a red giant now
I don't think we'll be able to recreate this in in this particular
Simulation because this simulation can be a little bit picky [about] the sizes [of] stars
Which might mean that it can actually destroy [the] star by accident, but imagine that one [day] this is
Kind of what starts happening to our sun it starts increasing in size it
Basically starts covering a lot of volume in our solar system and at some point will actually swallow Mercury
Venus and might even swallow our beautiful planet Earth, so goodbye Mercury
Goodbye venus and let's just stop right before we reach earth so right about here
[so] this is what we think might actually happen to our sun, or actually very likely it'll happen to our sun something like
4 to 5 billion Years from now it still has the [same] mass as before but Earth
Unfortunately will not be able to handle this it's going to become a fireball itself
[anyway], so that's the future for now
Then what will happen is this will actually fly away it will
release all of this material and we're going to use pulse here just to show you what it's going to look like and
It's essentially going to escape into the [our] solar system so all of this will basically
Be lost and what's going to be left on the [inside] is?
Going to be a white dwarf, and we can actually simulate this by doing the following
Boom as soon as I change the parameters here the sun
Becomes a white dwarf now. There's a few more pulses flying away from [Earth] for some reason
But that was I think my mistake now, so it here is our sun as a white dwarf. It's radius is very small
It's basically [just] a little bit bigger than our planet Earth. Which is right there and
It will stay as a white dwarf for trillions and quadrillions of years
Now obviously this is still not the end but our solar system will change dramatically after this happens because sun will have lost a lot
of its, mass
many of the Planets might either change their orbits completely or might even completely escape into the
our solar system or even become rogue planets and
our sun
assuming that nothing else happens to it is going to live out its days as
Basically a cooling white dwarf now. This is only about [6] billion years from now on and
Then every billion years. It's going to lose just a little bit of temperature
So it's basically going to become cooler and cooler and cooler
I'm not sure if I can try to demonstrate this here
But what I could do is I could just decrease the temperature just to give you an idea of what is going to start looking?
[like] in the future so right now. It's at
58,000 degrees, and we're going to start cooling it assuming that this is actually a
White dwarf that starts cooling down with time and also changes shapes just a little bit now
After many many meters, and we're talking about a number followed by like 16 to 17 zeros
it's going to start becoming Cooler and Cooler and Cooler and
Will one day
start becoming Darker and Darker and
slowly turn into
This it's going to become a black dwarf
Now this is a very hypothetical concept. We don't actually have this yet because our galaxy and our universe is not old enough
but sun as a black dwArf is
Essentially the future of our sun. It's going to stay as this black dwarf
For as long as the universe exists and what's going to be on its surface is essentially a very very
very thin very crystallized layer of
Carbon and Oxygen and there's going to become basically a very large you could almost call it a molecule
Because all of this will be crystallized and frozen forever
Until the universe ends, and that's essentially the life story of our beautiful son now
I hope you enjoyed this video
And I hope you learned something from it and now you know what's going to happen to our beautiful son
Until the end of its date, and how it was actually born as well if you learn something [from] this video
Don't forget to subscribe and come back here tomorrow to learn something else and possibly
Watch me play a video game [that] will teach you something really cool
I'll see you next video Kim you later guys and as always [bye]. Bye
