Surely you can't be Sirius.
I am Sirius, and don't call me Shirley.
Even if Sirius B goes supernova in several billion years, it will be much-much further away from us by that time. Remember - all nearby stars are in motion and in billions of years our solar system will have completely different neighbors.
Besides, we would already die by the sun's luminosity and size increasing by 10% every billion years, and even before that the Earth would get hit by an asteroid and end all life on it.
Stuff w/ DerpyGuy3333 yaaaaaaaa
Its supposedly near death
Sirius is moving closer to the solar system.
Uhhhhh actually Sirius is gradually moving CLOSER To the solar system
That tumbleweed moment where nothing happened lol.
Harry Evett I watched your videos

Lol
People in the comments, siriusly, get better jokes.
LOL, a good one
Civil Protection u don't boss us only if your suris
But *siriusly,* will it go in a nebula or in a supernova
Recorder Playing Weeb
Siriusly booooooooooooooop
Dry
why so ""sirius" kekeke
The Best I hate your puns
The Best
Do you know how i got these scars?...
Clorox Bleach From terrible puns?
Clorox Bleach dude I see you on so many vids
Kevin Sandoval "sirius"
Wow...This is serious.
Sirius*
No he's Sirius
Another video thumbs up. Nice one Anton loving these sandbox videos. I do have questions about the accuracy of the programme. But have no reason to think it's not. Crack on that man.
i actually wouldn't mind being able to see a giant nova in the sky leading me to my death...like that would be sick to look at at night
UA-cam just unsubscribed me from you...and they say their algorithm isn't broken
I don't even know yeah I noticed an unfortunate drop in the last few months. I don't know when they will fix this :(
same
Anton Petrov I just don't get why UA-cam won't admit it's an issue on their end
Go Fuck Yourself same!
did you get magically subscribed to the TYT instead - that's what happened to me, 3rd time unsub from TYT.
That's what I like about our universe, Everything happens in a billion years!
Haha yea that’s what they say today , scientist change all the time
No why UA-cam !? It unsubscribed me but I subscribed back, can't live without this channel you do amazing work.
How do you know i'm wonderful, thats amazing
Thank you for accelerating time, I just couldn't sit in front of my computer for 9 light years :) Well done on all your videos, very helpful.
I like evolution of stars in their lifetime. Cool.
Same.
You are made of their remnants.
The early universe was 75% Hydrogen and 25% Helium.
All other elements are produced in stars by fusion.
The Carbon of you flesh, the Oxygen you breath, the Calcium of your bones and the Iron in your blood come from 4 different ,now dead, stars.
We and all other life, the Earth and our Sun are reincarnated stars.
If we look at the stars at night, we watch our relatives.
We humans are the mirror where the universe becomes self aware.
thats deep bro
Lay down with that acid bro !
We're in Sirius trouble :)
Hahahha
Came for some Sirius puns.
Did not leave disappointed.
When they finally come to destroy the Earth, they'll have to go through you first.
I bet they won't be expecting that.
you say how we would be affected by the supernova, but you neglect to say that we would see it comming for well over a thousand year before it hit our part of the universe, we would know around 150 years after it happened because the light would reach here, then would be the waiting game for almost a thousand year or longer for any materials or any other energy other than light to reach here. love you videos man, please keep making them. huge space nerd and gamer here, so this sim is awesome to me.
SingingintheDark I think he’s worried about the gamma rays and other nasties.
Very cool demonstration!
A stars life, and death, is so volatile!!! When compared to a planet, which seems absolutely dull to the life of a star, the differences in activity are mind boggling!!! It’s fascinating and scary at the same time. It’s amazing. Simply awesome and amazing!!!
Anton, I'm pretty sure that with the recent uupdate, if you click on "Powers", choose "Explode" and change the energy to "1 Supernova", and if you try to explode a star with said power and energy, you'd get a supernova a lot more easily.
which software is this
plz tell
dying to know
universe sandbox you can buy it on steam
Holy Wyvern but it’s more fun to trigger it
he is looking for type 1 supernova not type 2 dupernova dumb ads
Thanks for the video Anton, Could you kindly share which astronomy software is this?
Imran Ahmed universal sandbox2
Very interesting. Great Vid !
my fav. channel for space facts
It was dramatic! Great video, I just was curious about Sirius B, after discover that it is the star with the bigger density near the Earth. Great!
Elite Dangerous brought me here! Nice vid Anton!
Im not sure about the mechanics of stars orbiting around the galatic center, but I figure in a billion years Sirius could be in another part of the galaxy altogether.
SwifterZee H He is correct. The orbital path of Sirius in the galaxy is different from our own and any minor deviation will bring it to a different part of our galaxy over a long period of time. But that's why he said it is very unlikely to happen to us.
The way I understand it the stars orbit around the galactic center in no particular formation, and aside from multiple star systems they typically don't have very much gravitational influence over each other.
In about 40K years time a star called Ross 248 will become closer then Alpha Centauri, and about 10K years later Gliese 445 will become the closest star; about 7 million years ago a large star called Algol was close enough to Earth to be 3 times a bright as Sirius is now.
Anton actually did a really good video about this a while ago. He has done so many I can't remember the name, but I learned a lot from it.
+EdMcStinko You are exactly right, the Sirius system will be much too far away from us to cause any damage. It's going to take about a billion years at the least.
and another perhaps even more dangerous potential supernova might be close, after we've wandered around the Milky Way. A billion yrs, that's another 5 rounds around the center of our MW....
Thank you for your very nice presentation. However, a question: I have done a very quick and simple calculation in which I computed the density reduction of Sirius B as it expands toward earth. My simple calculation shows its density will decrease to 1 over 0.5 times 10 to the nineteenth power. Does your simulator account for that level of density reduction?
Im guessing too close, no way we'd survive.
I'll die beautifully
Supernovae preserve the rotation of the original star, and material ejected from them mostly forms plumes which are ejected form the rotational poles of that star. So if that star's rotational axis isn't aimed at us, what we'd receive from that supernova would comprise visible and some infrared light.
I noticed that this video was made 4 years ago which means we have 4 years left.
damn, 70 years for a super nova to hit us from that distance. That's fast as hell universally speaking.
SO EDUCATIONAL!
White dwarf nearby explodes violently
Earth: _"Why so Sirius?"_
Even if we do get destroyed, we wouldn't even feel it.
Cool vid good job Anton
Hey Anton what program are you running these simulations on?
Love your new intro
That greeting made me like myself for a second lol
Love the videos Anton! What about the x-rays and gamma rays that travel at the speed of light? Would they be powerful enough to effect life on earth before the plasma wave reaches us?
I do believe that we are getting a bit mislead by the simulation here. The pressure wave is expanding from the nova at 0.2c, but that's not what you have to worry about for a star 8ly away. When a supernova explodes, it does throw off the outer shells of the star, but the luminosity and pressure wave is caused by the neutron, gamma, and x-ray flux - which travel at the speed of light. The immense flux energy is what lights up all the dust in the nebula. So, in reality, we will be toast the moment that the light from the supernova reaches earth.
Amazing - your channel is criminally undersubscribed.
Absolutely not, because by the time Sirius B reaches the mass limit (probably about a billion years from now) it will be *way* too far away to cause any damage.
The Supreme Sawk The simulation is just testing if it exploded now.
Juan Pedro Mariano Oh right lol
The Supreme Sawk i say it depends what constellation the solar system is in
Master Dan9 what you actually mean is the location of our solar system in the Milky Way. That means our solar neighborhood will be different than it is now
The Supreme Sawk Wow, you're brutal.
What is the name of the software being used in this video? It seems pretty cool! How valid are the event sequence scenarios he set up?
Bryan Blanchard the name of the program is in the title how tf do people not see it
Gonna be the craziest/wildest 30something years in history
You talking about my soul home there! 😤😢
What Software are you using for this program??
SIRIUS B is smaller than Earth.
No. White dwarf stars are the same size of Earth.
cozyin Sirius B isn’t necessarily smaller than the earth, it’s actually a little bit larger, it’s a white dwarf so it’s not that big at all in fact it’s really really small, for example you could fit about 1 million Sirius B’s into the sun. The sun being a yellow dwarf actually also pretty small.
"It could cause some Sirius trouble!"
The kill distance from earth from a Supernova is 25 light years. There are no Supernova candidates at that distance. Betelgeuse is a Supernova candidate but is some 650 light yeas away.
The little white dwarf just got supernovaed.💫💥😝💀💩👻
No horrifying death from a star in my lifetime? Fuck this universe
XD
How is it possible that such a small star could have enough energy to blast earth's atmosphere away with all the energy of the blast dispersed in a 8 light year sphere?
That's not like the energy of the supernova will be directed at us.
White dwarfs, are not stars. They are the remaining hot cores of dead stars. So if you add enough mass onto that core it will be able to restart nuclear fusion again causing it to go supernova.
This is me down here before watching the video. Me answering the title: Yes it will destroy earth, it would take about 8-9 years to reach us because it’s 8.611 lightyears away. In theory 8-9 years after the supernova when the gamma ray gets close to us, we would look up and be like “holy shit that’s bright,” then we all die from gamma ray.
Would it be one flash and then curtains or would we see it coming for years and then curtains?
By the time the cloud reaches Earth what other stars would it have reached? What happens to another star when that happens?
You should do a video to figure out what happens to Sirius A after Sirius B goes supernova. Will the A get kicked out of orbit and go rogue?
And unfortunately it turns out that this won’t just happen once but twice?
And that’s because our own won’t be a single star forever, and it turns out that our sun will get an introduced companion,
No matter if our sun becomes a white dwarf or not, our sun will have/capture a new companion star(probably/possibly during a galaxy collision),
And the random companion star will be ether a white dwarf or another main sequence star(such as a red dwarf),
And if that happens one of several thing could happen, and here are a few,
The new stars gravity could disrupt or fling planets out of the solar system, or possibly consume them,
And the thing that could happen next is that our sun will become a vampire(usually as a white dwarf),
And our sun will ether explode or become a turbocharged super hot white dwarf(this option is more likely than a supernova,mainly because most star are smaller than our sun,such as red dwarfs),
And if if our sun does explode in a type one supernova, the explosion will fling the planets out the solar system,
and possibly get blasted with radiation and debris in the process,
And another more theory is that our sun will become a neutron star(and I did suspect that this is not possible, but it is a terrifying logical idea),
And the neutron star left behind will feed on the companion star(or even the planets)first and then the rest of the objects(including the earth)!
But don’t worry about this terrifying question, that’s because it will probably never happen,(in a really long time, as long as 6 billion years or so)?!
Yeah, the temperature jumps alot, between -40,6 and -40,7 :D
07:48
You somehow managed to get rid of the atmosphere.
That's why there is a huge temp. drop.
I love ur videos
I am a kind of amateur astronomer myself. When a star dies, the middle class stars will explode to a Supernovae. Small stars will collapse to a white dwarf. Sirius B is allready a dead star. It can not die a second time. it will shribble up more but not explode.
Inconceivable!
Giant supernova appears in the sky
_"Are you Sirius?"_
It is scary that we will see our end coming for 8 years before it gets to us. Could you do a simulation on a recurrent nova and not a type 1A?
it would be cool if you combined all rock like planets in to earth see how big the planet would get and if life would develop on it
fascinating!
8:05 there is no shockwave, Anton. there has to be something for that energy to move to make a shockwave, and this is space. there's no air to create a shockwave
Gravitational waves.
Anton: ' We're practically inside the supernova now, and this is highly radioactive, highly radiated uh plasma that is basically going to leave like no life whatsoever but that does look absolutely gorgeous though, very very beautiful."
The downside is the end of the world comes but on the bright side at least it will be pretty!
Somewhere in all this, couldn't you have stated the orbital details, such as Sirius B's distance from A in astronomical units, perihelia and aphelia, for example. If a Type 1A supernova were to occur, what would the immediate effects be on the Earth and solar system, and gradual changes over months and years, instead of the abrupt changes in the Earth image over a few seconds. Things like that would be helpful and educational.
At lest we get a chance to see what supernovae actually look like
I saw Abraxas create a Type Ia supernova 9 light years away on his channel. However, the earth didn't get stripped of its atmosphere, he did it again with a previous version and the same thing happened the earth was fine. I don't know, now I'm confused and I don't know what to think about all of this. The only conclusion I got of both videos was that either you experienced a bug or he did because instead of using our solar neighborhood he used our solar system in his simulation.
That is.....chilling to see.....
I do hope we have the technology to block this sort of thing by the time it happens......
The first warning would be the supernova itself. It's the charged, radioactive matter that would do the greater and more lasting damage. But could we build appropriate shielding?
Sirius B? what in the world would Carl Sagan say about this... Are we afraid of "Little Dwars?" What would Sirius say about this, Eight Thousand Years from the light that we see now?
R.I.P earth the beginning of time - 2017
What effect would it have on all the planets and moons especially ice moons.
What is the program he is using, anybody knows? it looks like some kind of Stellarium extension
anton : welcome to what da math

This is the universe's way of giving humanity time to cope with its inevitable and unavoidable death.
Honestly by the time that thing gets here it will have already been programmed into AI as a primary threat even for its own existence and probably assist in changing form or if designed right to consider all life help us build electro magnetic field generator’s in our orbit to shield or reduce the effect from the nova
Is it only for me that few billion years sounds pretty short amount of time?
Awesome and nice.
If there is a Type-1a supernova in the Sirius system it will no doubt be towards the end of Sirius A's life as it enters the red-giant phase and starts expanding with its' outer hydrogen envelope getting close enough to Sirius B for it to start stripping it away and accreating the hydrogen onto its' surface. This of course would be hundreds of millions of years in the future.
Please simulate beeglejuce going into supernova. Thanks
A type 3 super weapon to use on terrains.
So how long will it take to get hear
The Earth is flat. Star is rezonans acustic.
We'll be toast as well as screwed.
there is a slim chance sirius could go supernova when the main sequence star turns into a red giant, by which time the binary system will be too far away to do any damage to earth, as the the sirius system and ours are moving away from each other
So we saw what happened to Earth. What happens to the Sun?
Nothing
Sun: you think you can even dent me? PATHETIC BAKE DE
@@JB-si1zd wouldnt it absorb the gas?
Sirius was observed as a red star a few thousand years ago. If Sirius B collapsed in historical times I wonder why it didn't explode then.
Rest easy anxiety. In reality we will be killed without having warning.
If it would collide but would we be close enough as the universe would expand to the point where the universe is so big the super nova cannot keep up the expansion of our universe
I didnt even know that a black dwarf existed... mind blown
Very cool program.
Wow I can relax now. Sirius B can't form a supernova until Sirius A becomes a red giant billions of years from now ...I don't plan to be around then anyway.
It's funny that everyone says that Sirius B is to far away to absorb material, but the last time I checked Sirius B has an elliptical orbit and currently has 1.26 M compared to the .98 M it had in 2012. I am being Dead Sirius.
Yo bro we're in sirius trouble.
Very bright now.
