+SilverDax holy shit also its going to be so damn bright in our solar system now that we cant sleep imagine all of those blue and greens we will see in the sky now it would be so annoying
+Mark Le (SupervGamer) I wouldn't take this as an accurate representation of what would happen. The gasses most likely wouldn't give off any light and the light that is given off or reflected would not be colorful. Basically the real thing would be very dull and boring.
1. The super nova expands at 0.1c which is hella fast 2. Its not gonna do any harm to our planet 3. Are you crazy? I would give anything to live when the super nova gets this close to our planet. I suggest you go look at pictures of stellar nebulae and imagine seeing one this big and bright covering our night sky
To me the most dangerous part of a Supernova is the radiation not the left over debris, now if this star is goes off supernova and it's 150 light years away then the radiation should reach Earth by 150 years after that, no matter how long it takes for the left over debris to reach us. so if Earth survives the radiation then the rest is safe as far as danger concerned !
A supernova within 30 light years happens on average every 240 million years. The earth is still here. There is still life on it. So clearly it's not a problem.
If the radiation travels at the speed of light, wont that mean that the radiation hits the earth at the same time the visual light does ie. we would have zero notice of the incoming issue?
I have an Idea for you Anton... Probably you should do a fan submitted suggestions from the comment section and pick the top 5 and show those top 5 in a Universal Sandbox 2 (Fan Comment based series). Sounds gut!
Well, he was playing a game at the time, Universe Sandbox! And it's all pretend and guesswork, not explaining a scientific paper to us in a way we will understand. That's a whole different dynamic. 😄😉
Take a look at "Suspicious Observer" and their vid about "Micro Nova" and the evidence of it being on a 12,000 year cycle. Likely associated with galactic waves similar to the solar waves that hit the planets. Magnetic anomalies are accelerating on Earth as we watch our shield weakening more rapidly. The Thunderbolts Project team and their "Electric Universe Theory" eerily tie in with this data and idea. There is other data that seems to compliment the cycle of destruction like the Mayan's calendar that ended in 2012. There is something lurking in our near future that is foretold in the Bible that looks a lot like what has been described in ancient civilizations catastrophe events. A very well known story found in the Bible, The flood and in other civilizations called the great deluge....
The thing that happened in 12 000 BC that caused the great flood and other kinds of destruction and rapid habitat change was very probably a shower of comet fragments hitting the Earth. There is geological evidence that that happened. This is also a cyclical event, since the swarm of comets it came from is still orbiting. Dont remember how long one cycle is though. Check out Graham Hancock, he has really good intel on that.
It's crazy to me how many people don't know anything about this... it's been researched and the fact that the CIA classified Chan Thomas's Book/ research is enough to verify its reality to me.
It’s a shame people still believe in humans relocating to the stars. It’ll never happen. The distance is too great and the uncertainty of anything habitable other than Earth to great. We are doomed to die on this rock. Humans will not last forever.
Who says humans have to specifically relocate to another habitable planet? With the way technology is progressing we could easily find ways to colonize moons and control the energy of the sun in the next few thousand years. From there we could migrate to other star systems near us and control those stars while colonizing more moons. Sails could get us to other star systems in a matter of decades with enough energy.
1: We won't be able to detect it until 150 years after it happens if it is 150 light years away. 2: The things we are worried about for distant supernova's really isn't to do with the expanding gas cloud, it's the high energy burst of gamma rays and other radiation that will wash over us in the moment it becomes possible to find out it even happened, if it's going to kill us chances are we will never even know it happened for that reason.
A supernova within 30 light years happens on average every 240 million years. The earth is still here. There is still life on it. So clearly it's not a problem.
You are saying the mass is the predominant reason why a star goes supernova. But what about the combounds that are in the star and the combounds that get absorbed, especially if these combounds are conflicting with one an other?
Might want to checkout suspicious observers catastrophe cycle videos. Our sun is on a 12000 year solar cycle of what is known as mini nova. Our ancestors tried to share what they saw in the form of petroglyphs during the younger dryas period. Diehold Foundation, Douglas Vogt, explains our solar cycle very well.
People in the future: "Hey, you ever heard of night?" "Night? No?" "Oh yeah, thousands of years ago the sky would go dark every 24 hours or so." "Really? That sounds awful, how did anybody do anything?" "They didn't, they would go into some sort of stasis, a sort of hibernation, they called it 'sleep'!" "Oh my god, so people only did things half of the time and then the rest of the time they'd just go unconscious?" "Yep!" "Damn troglodytes!" Also I saw a sort of advert video thing (idk what its purpose was) that was some people going around asking "would you like to live forever if you could?" and loads of people were saying yes. They obviously haven't given it any thought, imagine if you never perished, you're just here on Earth millions of years from now, when humanity has spread and there's no space left, no resources, so you're already starved and dehydrated but of course you don't die so... anyway long story short the Sun sheds its shell and fries the Earth and you're just hanging around to get toasted. You would not want to live forever, even if forever is a thing. Certainly wouldn't wanna be around when the universe goes through heat death and all that's left are black holes. That's my 2 cents.
Betelgeuse in the constellation Orion, that will not present any danger to earth at 600 light years away.We are seeing the expansion now. It is estimated that we will see it nova within 1,000 years. good video thanks.
mypersonaljesus1 If we are still around by that time, we will most likely have transcended into some kind of borg-like being that isn't affected by radiation anyways, and moved to another solar system to boot. So there's really nothing to worry about. :)
Anton, if it is 150 M light years away, we will spend 150 M years of not seeing it. There is a chance that it is already a supernova, but the light hasn't reached us.
Sometimes i'm sad that not many girls i know loves astronomy 😥. Because i can't discuss this with someone i'm comfortable with. Come on girls, stars and supernova is as interesting as eyeshadow and clothes.

What happens to the companion star when one goes supernova? Does the other star survive? Remain in it's orbit? Does it absorb a lot of the material from the supernova and maybe even become "younger?" Or does it explode as well, or get kicked out of their orbit, or lose all it's material and just leave a white dwarf? Does the white dwarf that went supernova leave a remnant? I don't think it's massive enough to go black hole, but neutron star maybe?
- NO! The Sun will only "Nova"; that means it will swell up to a Red Giant size & swallow up the earth. - And we will not crash into another galaxy but pass right through it cause both Galaxies overall density is like wisps of smoke relative to their huge size. But most of the orbits will be disrupted & both spiral structures will be morphed into one football shaped ecliptical with a binary super massive black hole pair @ its center. - Now, if the two bkack holes Merge into one then the gravity waves may do some damage to the white dwarf remnant called our Sun.
I thought the most interesting part was that for a few hundred years earth's temp dropped around 11-12C and stayed there for a while before going back to around 13-14C
So in the far future, we would not need streetlights, but what would be the effect on nocturnal animals? As an example, some deep sea fish come closer to the surface to feed during the night.
Love this video. The thing that would suck is that the night sky would be very less dark and I wouldn't get very much sleep 😔 but the good news is I'd get to see that beauty in the sky. Space is really cool!
Had IK Pegasi suddenly exploded in the late 19th century, we still wouldn't know it, since the first bit of light from the explosion would take 150 years to arrive. :3
The program you were using didn't seem to include the motions of the stars relative to each other. If this star and Sol are separating at the rate of even 0.2 lt.-yrs. per millennium, then 1 million years from now it will have moved away an *additional* 200 lt.-yrs. (to about 350 lt.-yrs.), *greatly* reducing the potential hazard! You should see if there's a star moving *towards* us, that *would* be a supernova candidate when it's near us! Really enjoy your pieces! Even when I spot a (potential) weakness (like here), it's still good as 'food for thought'!
The actual supernova remnant doesnt have to reach earth to do any damage. The radiation damage comes from gamma rays (traveling at speed of light) and high energy particles (traveling at near speed of light), which reaches the earth around the same time or shortly after the supernova becomes visible. Also, the extinction events occurs from harmful doses of radiation as well as damage to the ozone layer, and not from any climate change that is detectable in universe sandbox. But its true it must be closer than about 10 parsecs to cause such events.
The important fact is, the light is not what kills us, so we see it many many years before the energetic particles get here. That was something I did not know. @9+. So, many generations in the future.
If there are "Us" in 5 000 000 000 years... we will mine Stars for materials , and lowering their mass will stop them from going super. Not even need fusion for this." Isaac Arthur" < this guy explains it perfectly.
At a distance of around 150 light years, the explosion debris or the gas might not reach us at all. Because if the white dwarf explodes due to the enormous amount of materials it absorbed from the companion star, the force of the explosion will turn that white dwarf into a very dense neutron star. The enormous gravity of the neutron star will slow down or might even halt the expansion of the gas. And since that star is moving away from us, the speed of recession might even exceed the rate of expansion of the nebulae. What worries me is the amount of radiation that might reach earth. Although a large portion will be blocked by the upper atmosphere resulting in the aurora or northern light like display, a substantial amount of radiation might reach the surface of the earth that might affect the most delicate life forms on earth.
Eta Carinae is ~50X further away, but it could go hyperbola any time now - and indeed probably already has gone hypernova but the flash just hasn't gotten here yet. It isn't so much the total energy, but the energy/time impulse that could momentarily heat the surface of the earth to ignition. Eta Carinae is only visible south of the Mexican border, so there is no extinction potential. Still, someone (you?) should do he math on Eta Carinae to see if it could be a flashbulb that could ignite the side of the earth facing it when it goes off.
we are safe from any kind of space danger. if a star would enter the system, the planets would go fireworks away, the star and the sun will go binary until they either collide or seperate, and we will find a new star to orbit. a black hole is kinda different, cause the gravitational pull will keep the black hole and the sun in a binary system possibly forever
Technically, there could be adverse effects on us- probably an EMP that would be blocked by the athmosphere but still enough to cause damage to possible colonies on the moon or mars at that time, assuming that they are not protected with artificial magnetic feilds or athmospheres, which on mars could be doable
So what is the actual density of space once we are encompased by pegasi nebula? I assume hydrogen will be flooding our star system allowing the heat of our own star to radiate outward much more efficiently and the oxygen of our atmosphere to go to water? And Oumuamua is apparently supernova debris so chunks will reach us eventually, and the small dust travels faster than the asteroid sized stuff so it will get bigger and bigger and then it will be like the boots void in there. I think of all those starsystems between us and pegasi who will take far more damage. Those little alien children whose lives will be snuffed out.
What if our Star Micr-nova's though, as some believe happened around 12,000 years ago. The DieHold foundation and other have done extensive research on it's effects on the past, and past extinctions.
I’m not sure such a simple simulation can give you all the potential fallout from such an event. Even just the added bright light in the night sky could change biological patterns that rely on nocturnal dark cycles.
And I think that the Sirius threat to earth will actually be the brightest star in our night sky, And it’s slightly farther very similar system, such as the Procyon system, And what these stars have in common is that both of these stars have a white dwarf companion!
Kinda cool to see how the planet's continents have shifted into each other by year 10,000 or w/e. At least according to this simulation. Around the 16:03 mark. The US and Russia and Greenland look like one massive continent. Or I am dumb lol.
Heya Anton, in your experiment in this video I was wondering, Since it took more than nearly 1500 years for the particles to reach earth or our solar system to begin with, in what way would those particles (based on what kind of radiation and particle it is) be affected by our own suns heliosphere. We know that the cosmic radiation inside our own heliosphere bubble is much less since our sun also protects our solar system a lot. Would like to hear your thoughts on how the heliosphere would protect our solar system. Peace! Loved this video! keep the nice contend going.
Would it not be possible to have a cascading effect of supernovae; if a supernova occurred near two or more white dwarfs? If so, what would the minimum safe distance for a white dwarf of sufficient mass to become a supernova be?
Even if we do survive the blast, you still gotta remember the Sun is now a dead star, meaning, its getting colder and colder. Earth will become an ice cube.
Well, we Can't exactly run away and colonize another star system as the supernova wave would also get any planets that we could run to. So you might as well sit on the beach a beer enjoy the view.
That’s maybe what happen to Mars and venus. When a very close super nova explode near our solar system That boiled these planet a few million years ago
By the time that those particles reach us, they'll have time to get diluted. The density will probably be less than that of the Solar wind around Neptune. First interaction with the Solar system will be with the Sun's magnetosphere and Solar wind. It will deflect and repel a large part of the incoming particles. Next, what left will interact with Earth's own magnetic field that will harmlessly deflect it. At most, we'll have to see more auroras.
Here is something to think about: if the speed of light is unsurpassable then technically it is infinite. But if we can measure it then technically it is not infinite. That must mean that the speed of light is surpassable. it might take a while but still.
Anton, can you try creating Pulsars at different distances with their particle axis intersecting Earth to see what type of damage might occur. I have heard that On Axis intersections could be fatal to life even from extreme distances...
question?wouldn't we be able to survive that?i mean around a million years later we would be already a tier 3 civil and we may find other dimensions to live in,whenever our dimension dies u go to another dimension and when that dies you go back to your normal dimension,because the whole world is infinite after a trillion years the black holes will collide with each other to make a very big one and then destroy the world and then another big bang comes and creates another universe?we would be godly at that time XD

the radiation can probably do some half lives by then, so most of it may have disapated, depending on the kind of radiation.

We are fairly safe, distance and time. 150 light years is a huge distance, and million years is far far in the future to be of any concern to us.
by then we'd have colonies on other star systems, so we'd probably send a colony ship out to look for a new home by when it's a real danger.

Kac The Red Panda i was thinking about it as "if i was alive in the future i'd like i'd like this but dislike this"
Had IK Pegasi suddenly exploded in the late 19th century, we still wouldn't know it, since the first bit of light from the explosion would take 150 years to arrive. :3
no we won't die. if we do who cares
That's an unfinished s c e n t I n c e Full s c e n t in c e no we won't die if we do who cares well die before it super novas
I was expected thus to be about GRB events.affecting the Earth.
That would be so beautiful to see in the night sky
Right that would be insane I'm jealous already
What will the plasma cloud do to the Oort cloud, the Kuiper Belt the gas giants or space travellers etc.?
You didn't say "hello wonderful person" ...oh this was shot in 2016. Hello wonderful person from 2019~!
Real simulation would take gargantuan sized supercomputers but I'll settle for this. :-)
The program you were using didn't seem to include the motions of the stars relative to each other. If this star and Sol are separating at the rate of even 0.2 lt.-yrs. per millennium, then 1 million years from now it will have moved away an *additional* 200 lt.-yrs. (to about 350 lt.-yrs.), *greatly* reducing the potential hazard! You should see if there's a star moving *towards* us, that *would* be a supernova candidate when it's near us!
Really enjoy your pieces! Even when I spot a (potential) weakness (like here), it's still good as 'food for thought'!
The actual supernova remnant doesnt have to reach earth to do any damage. The radiation damage comes from gamma rays (traveling at speed of light) and high energy particles (traveling at near speed of light), which reaches the earth around the same time or shortly after the supernova becomes visible.
Also, the extinction events occurs from harmful doses of radiation as well as damage to the ozone layer, and not from any climate change that is detectable in universe sandbox. But its true it must be closer than about 10 parsecs to cause such events.
The important fact is, the light is not what kills us, so we see it many many years before the energetic particles get here. That was something I did not know. @9+. So, many generations in the future.
If there are "Us" in 5 000 000 000 years... we will mine Stars for materials , and lowering their mass will stop them from going super. Not even need fusion for this." Isaac Arthur" < this guy explains it perfectly.
At a distance of around 150 light years, the explosion debris or the gas might not reach us at all. Because if the white dwarf explodes due to the enormous amount of materials it absorbed from the companion star, the force of the explosion will turn that white dwarf into a very dense neutron star. The enormous gravity of the neutron star will slow down or might even halt the expansion of the gas. And since that star is moving away from us, the speed of recession might even exceed the rate of expansion of the nebulae. What worries me is the amount of radiation that might reach earth. Although a large portion will be blocked by the upper atmosphere resulting in the aurora or northern light like display, a substantial amount of radiation might reach the surface of the earth that might affect the most delicate life forms on earth.
Why aren't more people watching this (kind of videos)? Very interesting! Keep going!
Eta Carinae is ~50X further away, but it could go hyperbola any time now - and indeed probably already has gone hypernova but the flash just hasn't gotten here yet. It isn't so much the total energy, but the energy/time impulse that could momentarily heat the surface of the earth to ignition. Eta Carinae is only visible south of the Mexican border, so there is no extinction potential. Still, someone (you?) should do he math on Eta Carinae to see if it could be a flashbulb that could ignite the side of the earth facing it when it goes off.
we are safe from any kind of space danger. if a star would enter the system, the planets would go fireworks away, the star and the sun will go binary until they either collide or seperate, and we will find a new star to orbit. a black hole is kinda different, cause the gravitational pull will keep the black hole and the sun in a binary system possibly forever
Don’t forget about Betelgeuse. 640 light years away and it could go supernova within 300 yrs. it’ll be the 2nd brightest object in the night sky
Technically, there could be adverse effects on us- probably an EMP that would be blocked by the athmosphere but still enough to cause damage to possible colonies on the moon or mars at that time, assuming that they are not protected with artificial magnetic feilds or athmospheres, which on mars could be doable
So what is the actual density of space once we are encompased by pegasi nebula? I assume hydrogen will be flooding our star system allowing the heat of our own star to radiate outward much more efficiently and the oxygen of our atmosphere to go to water? And Oumuamua is apparently supernova debris so chunks will reach us eventually, and the small dust travels faster than the asteroid sized stuff so it will get bigger and bigger and then it will be like the boots void in there.
I think of all those starsystems between us and pegasi who will take far more damage. Those little alien children whose lives will be snuffed out.
What if our Star Micr-nova's though, as some believe happened around 12,000 years ago.
The DieHold foundation and other have done extensive research on it's effects on the past, and past extinctions.
Electrical power will be fond memory as every electrical device on earth will burn out, even the generators.
I’m not sure such a simple simulation can give you all the potential fallout from such an event. Even just the added bright light in the night sky could change biological patterns that rely on nocturnal dark cycles.
And I think that the Sirius threat to earth will actually be the brightest star in our night sky,
And it’s slightly farther very similar system, such as the Procyon system,
And what these stars have in common is that both of these stars have a white dwarf companion!
Kinda cool to see how the planet's continents have shifted into each other by year 10,000 or w/e. At least according to this simulation. Around the 16:03 mark. The US and Russia and Greenland look like one massive continent. Or I am dumb lol.
Heya Anton, in your experiment in this video I was wondering, Since it took more than nearly 1500 years for the particles to reach earth or our solar system to begin with, in what way would those particles (based on what kind of radiation and particle it is) be affected by our own suns heliosphere. We know that the cosmic radiation inside our own heliosphere bubble is much less since our sun also protects our solar system a lot. Would like to hear your thoughts on how the heliosphere would protect our solar system. Peace!
Loved this video! keep the nice contend going.
Wonderful close call supernova
What about the effect of X-rays? gamma rays, and UV?
If this happens our descendants won't see most of the night sky, it'll be blocked out by the supernova.
By the time it reaches us, it will be PRETTY attenuated.
Your channel is awesome just bought universe sandbox 2 and subscribed
Would it not be possible to have a cascading effect of supernovae; if a supernova occurred near two or more white dwarfs? If so, what would the minimum safe distance for a white dwarf of sufficient mass to become a supernova be?
death by supernova sounds way better than freezing to death because our sun keels over and dies.
Even if we do survive the blast, you still gotta remember the Sun is now a dead star, meaning, its getting colder and colder. Earth will become an ice cube.
Explain why.
8:46 the date when no car immisions are supposed to be made
zToxic Anime
Man I wish I would be around at that time, it would be like having the night skies of skyrim wherever you go.
Well, we Can't exactly run away and colonize another star system as the supernova wave would also get any planets that we could run to. So you might as well sit on the beach a beer enjoy the view.
That’s maybe what happen to Mars and venus.
When a very close super nova explode near our solar system
That boiled these planet a few million years ago
By the time that those particles reach us, they'll have time to get diluted. The density will probably be less than that of the Solar wind around Neptune.
First interaction with the Solar system will be with the Sun's magnetosphere and Solar wind. It will deflect and repel a large part of the incoming particles.
Next, what left will interact with Earth's own magnetic field that will harmlessly deflect it. At most, we'll have to see more auroras.
At the end, it seemed the Earth became cooler. All the debris will start blocking sunlight.
This night sky looks so brighter
It might affect evolution a bit maybe our eyes might adapt to the new light in the sky in some way.
Here is something to think about: if the speed of light is unsurpassable then technically it is infinite. But if we can measure it then technically it is not infinite. That must mean that the speed of light is surpassable. it might take a while but still.
Hi Anton, what astro software did you use in the movie clip?
The light would arrive 150 years after the event, so the explosion would have advanced that far before we knew anything had happened.
Don't be afraid. When is blows,it will be a harmless beautiful show. It is not a GRB.
You are a very good teacher.
at 14:33 that cloud looks creepy.
good vídeo.
in future videos you can look whats happening in other planets and moon in which we could live ( hundreds years later)
Anton, can you try creating Pulsars at different distances with their particle axis intersecting Earth to see what type of damage might occur. I have heard that On Axis intersections could be fatal to life even from extreme distances...
This implies that there may be habitable planets inside some of the nebulæ we see.
What about the concept of a red nova? we are gonna get one pretty close in 2022.
Oh. OK. I guess the more immediate threat is Wolf-Rayet 104....
What is a bow shock of the sun's magnetic field get the majority of the ionized particles out of the star system
question?wouldn't we be able to survive that?i mean around a million years later we would be already a tier 3 civil and we may find other dimensions to live in,whenever our dimension dies u go to another dimension and when that dies you go back to your normal dimension,because the whole world is infinite after a trillion years the black holes will collide with each other to make a very big one and then destroy the world and then another big bang comes and creates another universe?we would be godly at that time XD
forgetting one thing all that ambient light being cast on the Earth 24/7 will affect climates and plant and animal life directly.
Astronomically speaking, Taco Hell does cause Hypernovae!
Thank you for the awesome video Anton 🤘🤘
