Betelgeuse, that's pronounced 'beetlejuice', exploded 500 years ago as retribution, not for the Peasant War like we first thought but for what King Henry the VIII said to Pope Clement VII when the Pope would not grant the divorce.

Interesting and informative. I would suggest one thing, though. When you cut to captioned illustrations, they are not on screen long enough to both read the caption and look at the picture. Either give a few seconds longer to each slide, or remove the caption and speak it, while the viewer looks at the picture. Other than that minor point, this was most enjoyable.
642 light years away = beautiful = so it would be a magnificant display in the sky and = WE ARE ALL FAFE = for our lifetimes at least = BLESSINGS TO YOU ALL !
Beetlejuice in all likelihood ALREADY went supernova, but its light has yet to catch up to us. The 1st indication would be the flood of neutrinos from the collapse that would arrive before the first visible (and invisible) light from the explosion itself.
Betelgeuse might go supernova in the next 100k years, how do a couple hundred then qualify as "in all likelihood"? I also wish, I could see it happen, but unfortunately the universe doesn't conform to my personal desires.
@@CertifiedClapaholicNo. Neutrinos barely interact with normal matter and will be emitted as soon as the core collapse begins, and then they will just pass through the star unimpeded. Meanwhile the shockwave will need to force its way through the entire star until it reaches the surface and actually blows it apart and that will that upwards of several hours. A powerful burst of neutrino emissions will reach Earth based detectors hours before the light does.
@bitemyshite Yes. A neutrino emission powerful enough to be detectable from Earth across hundreds/thousands of lightyears, originate pretty exclusively from core collapse supernovas. Thing is, Neutrinos are released when the core collapses and pass through normal matter unimpeded, while the flash we commonly associate with supernova is the last step of the chain reaction, occurring once the shockwave resulting from the core collapse forces its way through insanely dense stellar material, reaches the surface of the star and blows it apart. And that happens several hours/days after the core collapse itself. That's how we study supernovas. A powerful burst of neutrinos reaches out ground based detectors, and we point our telescopes in the direction they came from, awaiting the light show a few hours later.
@@Stubbies2003 its been dimming and brightening oddly and nobody quit understands why, it may be prepping for a supernova in our lifetimes, (meaning its explosions light may reach here soon)
A star went supernova in the Pinwheel Galaxy visible in 2023, I'm lucky enough to have taken a picture (as did many others) of the Galaxy prior to and after the supernova. It only looked the a new star popped up but it was really cool to see with the knowledge of what it actually was.
@@rdelrosso1973if it could. Nothing. It would be revelations. The atmosphere would blow off like a screen. We would be exposed to space radiation. Imagine a nuke but from above and the size of the sun. Luckily we wouldn’t get much energy cause usually energy dissolves in waves in all directions. So the further we are the less degree of “energy” we would receive.
Astronomers calculate Betelgeuse at some 700 light-years distant, its diameter bloated in size to about out to Jupiters' orbit in diameter...the axis point off about Fifteen degrees. This axis point is important as jets of energy are expelled along its axis...these jets can dangerous at immense distances.
Your video title promised some wild speculation on what would happen to the Earth today if Betelgeuse went supernova... And it did not deliver! I should have known better when I didn't see an apocalyptic thumbnail image for the video.
It doesn't mention earth but I had to check. The speculation about every single other thing in this scientism propaganda piece is void of any provable facts. Sad.
I was taught that it's to far away to have any real effect on us. Although, it would be bright enough to light the night sky for two weeks. It would be lit up like dawn.
None of the stars near us will ever affect us. It will be as bright as the full moon at night and will be visible for several weeks. We will also be able to see it in the day.
When you look at the constellation Orion, at Betelgeuse, you see it not as it is now, but as it was centuries ago. It takes light that long to get from Betelgeuse to here.
This gives you an idea about distances in space. Light can travel around the earth about 7 times a second, betelguise could of already exploded before Shakespeare was born, the light just hasn't reached us yet 😮🤯
Um, when something happens now, that's called now. Effects wouldn't happen for a long time. But still, when they happen it'll still be now at that time.
when you have black holes and neutron collisions eclipsing its host galaxy by folds of magnitude it truly puts into perspective our tiny little star in how easily life can be extinguished by such an explosion.
If it exploded just now, what would happen to the earth? Nothing right now! Betelgeuse is some distance from us, Astronomers suggest 422 +/- lights, but the distance is debatable. Some astronomers suggest that the earth is too far from us but honestly that can be debatable. Let’s say it did blow and it has since gone supernova, we will not know for 500 years. However I saw a story about Polaris the north star, that star is acting up. But if we were much closer, better pray….

It might have already gone supernova but since it's about 640 light years away, we wouldn't see its light image for (640 - x) years. x equals the distance in light years the supernova light image has already traveled in the vastness of space.

Haven't watched this channel in a minute and this new voice is very disconcerting and I don't like it much. Edit: I've never watched this channel before-- I thought this was a 'What If' video... 😳🤷♀️
Just a cool light show. Since the star is some 650 light years from earth, plenty far enough outside the "blast radius". If it went off in the sky now, it actually happened over 6.5 centuries ago. Food for thought.😊
There will be a bright light in the night sky. There will be a brilliant light show for anyone here to see. Over a period of months to a few years it will gradually fade from view. Beyond that, we are in no danger from Bettalguese.
It would take radiation traveling at the speed of light to reach us from Betelguise exploding about 752 light years. Any blast debris would take thousands of years to reach Earth.
IF you came here to find out about Betelgeuse this video contains 16 minutes of useless fluff padding. Skip to ~16 minutes if you don't want a long, repetitive lecture on supernovae. Even then you're going to have to sit through even more repetition and probably won't find out anything useful. This would appear to be one of those AI generated videos that are now plaguing the information age.
If it exploded this very second i understand that we will not see it for many years to come due to the massive distance light has to travel in order for us to see it. But could the JWST see it fairly soon after it actually exploded due to it being able to look extremely long distances?

Well, right now as others pointed out Nothing! And By The Way, stop calling this star Beetle Juice, It is called Betelgeuse, You don't call the Polar Star Polystar do you? So call this star by it's right cataloger star name please. The Red Super Giant is about 580 to 600 light years away in Orion, So even if it went up now it would be 580 to 600 years if the blast wave was going at light speed before it even got here in the Sol System. and even then no problems as by that time the wave would have been almost nothing in strength. But since the blast wave be most likely only going at the most 10% of light speed it would take Thousands of years to get to our star system. And any Neutron star or Black Hole left after the Super Nova would also be so far from us those too would be no problem. So no no problems for our future humans. Since none of the possible Giant Stars out there that can go Super Nova are anywhere nearby us, We live in a stable part of the Galaxy. If We don't then we would not be here alive like we are.
Need a medium for there to be a "blast wave." This is space, and gravity waves won't hurt you. You're more at risk from the narrator throwing empty PBR bottles than this star going nova..
It's so fascinating how we haven't even really left our own backyard yet we already know this much about the life and death of certain objects across the cosmos. It's truly impressive.
In answer to the title question, as far as we are concerned, not a lot. Because even light takes time to travel the vast distance, it would take a number of years for that light to reach us. So, Betelgeuse could explode now, and we wouldn't see the light of it until it reached us... As for the tag, 'We're not ready!', we don't have to be. Betelgeuse is too far away from us for any harmful effects to reach us. At best we'd have a second bright light in our sky during the day, but that's about it. That and the fact that the constellation Orion will forever be missing a key component, that is.
Depends. Gamma-ray bursts are dangerous much farther away than only 600 light-years, which is this star's maximum distance. If the burst is pointed at where our general direction will be (400-600 years in the future) there may be trouble.
@@brianhammer5107 You still missed the point. Carolyn is pointing out that the whole "we're not ready" is click baity and she would be 100% correct. Even if a GRB was produced by Betelgeuse going supernova and somehow pointed directly at us what in the world are you, or the video maker, suggesting we can do to "be ready" for it? Or are you suggesting that everyone make a "bomb shelter" underground made with thick lead walls in the super rare chance that not only does that supernova happen but also makes a GRB pointed directly at us?
Why dies the narrator say type "eye" a and "eye" other letters, but when he speaks of Type II suoernova, he then switches to numbers, saying two instead of double "eye" or "eye 👀 eye." Strange.
What he is actually saying is "supernovae" which is the plural of supernova. How he could know that and yet confuse Type1A supernova as being Type IA, I have no idea.@@zanetrukk
@@deedubya286I strongly suspect this is a text-to-speech bot reading a script. For me, the giveaway was the strong southern/texan accent, yet it pronounces "nuclear" correctly.
Great video first time seeing your channel in my feed liked and sub’d…. When bettlejuice does go nova do we know if there are any planets in its orbit and will we be able to detect the impact on them??? Many thanks for sharing 🍻👍
The probability that supernovae themselves can induce detectable ripples in spacetime detectable in gravitational waves is pretty unlikely to occur and to be detectable would likely require a LIGO type observatory in space on a magnitude of close to the Earth - Moon orbit. Ninety-Five percent of the mass of a Super Nova stay relatively close to the star during the gravitational collapse of the star and resulting expulsion of the outer layers of the star resulting in much of the mass collapsed into a white dwarf but still gravitationally stable in essence with relatively much the same spacetime gravitational annealing in place but expanding only due to the materials shed.

Are y'all old enough to have seen the movie/show/series where a kid had the unique ability to predict the future? And one day he said, "Our sun will supernova tomorrow" Everyone around him quipped back, "No! Not! It's only going to supernova because you said it will!" He told them, "No! It's fact! Our sun will go supernova tomorrow no matter what!" .....and, it did! I thought like the the others, that yes, it will happen only bc he said it would! Y'all hafta know that 'yes' there is that possibility only bc he said so! Anyway, I thought it quite an interesting conundrum that it would only happen bc 'he said so!" ^..^~~
Astronomers think that Betelgeuse is about 600 light years from Earth. That means if that star exploded NOW, we on Earth wouldn't see that until approximately 2624!!!!!!
Well if it happens --- It happens. Nothing we can do about it. That is the Universe for you. Our planet is very fragile and anything can happen, Galaxies Colliding with each other, Star Super Novas Gamma bursts, Magnetic Poles flipping, Our own Sun solar Flares, Meteors striking the Earth, Mega Volcanos, etc - to name a few Other than that, have a nice day.
Absolutely Nothing!! Whatever could or, may, or already have happened to Betelgeuse we wouldn't know for at least 650 years after the event, admittedly. when we do see it, that light has traveled that distance, so any adverse effects in its wake will be right behind it. How could, would we know instantaneously?🤔 Unless you know of and believe in Quantum tunneling? A mind-blowing equation and subject that seems factually proven, possibly in use today!! A conversation for another day.😊
What would happen? Absolutely nothing is the answer. For starters, even if it was close enough to cause damage and exploded today, you will be long dead before it reached us. However it’s not close enough to do anything. Again, if it exploded today, we wouldn’t see it or know for another 650 to 700 years due to its distance. When you look at the star, you seeing it as it was that far in the past, not as it is now
Though Beetleguese is unstable, it could last another 1.000 years, or even 10,000 years or 100,000 years before going Nova. Nobody can predict when it will explode .
The actual distance is not agreed upon by astronomers and astrophysicists. They're saying it could be anywhere from ~500 light years away to maybe ~850 with the actual number being somewhere in between. Either way it won't hurt the Earth's biosphere but it will be a great light show. I hope the wavefront arrives while I'm still alive to witness it. edited to complain about the lack of a proper ending for the plural of supernova. English would have it be supernovas and Latin it would be supernovae. He's (the computer or narrator) is pronouncing it as though it's the Latin but the closed captioning is spelling it like the singular. LOL we know there's more than one...
We would understand if gravity and light travelled at the same speed. Light travels through space time. But gravity is space time. So a supernova causes ripple in space time. I understand current thinking has them the same speed. But maybe it isn’t. This star giving us a supernova will verify that. We have an observation limit of the speed of light. In theory we cannot measure anything faster. If anything faster exists. However just say it’s 500 years away by light. We may experience the gravity wave ripples at the same time, 20 years before or say 100 years before. I doubt it would be after.
Everything you see in the stars happened long, long ago. It’s ancient history. If anything happens to Betelgeuse, we won’t know it for 700 years unless it already happened. Who knows what the next minute brings……….🤔😳
Kuiper Belt? Bok globulars? 12,000 year repetition, in line with mass extinctions and rapid ice-age thereafter - now, where in our system could that energy come from? 🤔😊🖐🏻
Betelguese could have already went supernova, and we wouldn't know about it. It's over 600 light years away from Earth, so we are seeing light that was emitted by Betelguese 600 yrs ago. It could have exploded in the meantime, and we wouldn't see it until the light from it reaches Earth, sometime in the next 600 or so years.
Oh, another of these robotic voice videos talking about apocalyptic things. If you're lucky enough to see at night, you'll see an object almost as bright as the moon for a couple of seconds (think of it as having 2 moons momentarily). In daylight, maybe if you see at dawn or dusk, you'll see a fainter "moon", in between those hours, you might catch a glimpse if you know where to look with a telescope, depending on your local air pollution. So no, no cataclysmic event, no Earth dying because ozone layer destruction, honestly, I'd be more worried about flossing too close to my gums than a supernova.
Sigh. As soon as I heard the narrator's accent I knew. Took a while until I heard the word that made me shudder. Fahrenheit. In 2024. The measurements of science is Metric. The fact that about 400 million people out of 8 billion still insist on using Freedumb units saddens me. Another 'Don't recommend channel'. These channels should be extinct.
I Believe, after a dream I had of volcanoes going off in Williamsburg pa, I awoke to walk out of the Mr Farley's area to see dark red black orange in the sky for about three seconds my heart beat so hard then I woke up but it was so real to me I have been studying cosmology and things that could possibly caused my dreams situation...I however do not know it was either beetleguese going supernova or Yellowstone going off all I know is I died in the mess my mind wouldn't lete believe anything different..it seemed like ifd be returning to dreams in real life ...note to my probation officer do not send me to rehab please ...or partial cuz shit is going to hit the fan especially around April may...no f*"#ing joke
Due to the distance Betelgeuse is from only our solar system sun. The image of it going boom today wouldn't get here for some 6.5 trillion of our current 24/7/365 day year's. IF we were to see it happen today. Meant that because of light travel's considerably faster and farther than any object's caused to be put into motion in a trajectory that could ever reach our solar system let alone our planet. Would have had to happen more than 6.5 trillion year's because the object's wouldn't be going to a degree as nearly as fast as the image is. Light is faster than sound, and sound is faster than any object who's trajector some 6.5 trillion year's away would eventually reach us. There are concern's and there are resolve's to concern's. Though neither have to be actaully true, they do depend on being pitched correctly to the ignorant.
If Betelgeuse burst right now we would not know for 500 years. What is meant by "being ready," I have no idea. This I am sure of, politics would not let us "get ready," if there were something we could "get ready." I do not think there really is anything we can do.
The real world issue is when the results reach us. Comments about how long it takes to get here contribute nothing. It might have already happened. Maybe hundreds of years ago, maybe days ago. So won’t know that answer until it arrives. At that point, the discussion is moot. The ONLY discussion of value is whether we are “hardened” enough, and prepared for the impact.
What Would Happen If Betelgeuse Burst Right Now ? pretty much nothing for the next 724 years, then we would see it or if we see the Super Nova right now, then Betelgeuse did blow up 724 years ago !
From my point of view, nothing. Maybe it already has but at approx 642.5 light years away... I'll either be long gone or I'll go out and see something...
We live in a universe where objects are placed unbelievably vast distances apart, and the speed of light or rather the speed of electromagnetic radiation is such that it takes massive amounts of time for this radiation to travel between these sparsely spaced objects. So Beetlejuice is over 600 light years away from planet Earth. Anything that happens in current time at Betelgeuse will take over 600 years for us to observe it. It could have already had its supernova, but the electromagnetic radiation that we would observe of that event hasn't gotten here yet. Everything that we observe about our universe is in the past.
Well if it happens as I'm typing this post I'll have been dead over 600 years before anyone on earth knows about it so I don't really care. If it has happened 640 years ago and we're just finding out now since it's 640 light years away I doubt it will affect the earth at all. So again I don't really care.
The short answer is nothing. Mite be something interesting to see in the sky. Novaay, what's a Novaay. You say it correctly sometimes, other times ---. Anyway, it's trillions of miles away, no issues.
It could go supernova tomorrow and we wouldn't make no difference. For it to affect us today, it would've had to happen in the late middle ages (1300AD).
I've seen and heard everything in this sad little regurgitation on UA-cam over the last few years now. If this was a Jr. High school project I'd give it a *D-* for plagiarism.
More sobering question is what would happen if a beautiful, yet failed human experiment on a a tiny planet named earth. Were to multiply insaneky, practice dividing and substracting one anither to an art form over thousands of years. Crawling across the planets face, devouring their only home..fubar. oh, shit..that us what has actually occured. In the end so few get ut while the rest if us pretend and do the same sames.
They are telling us that Betelgeuse will go nova this year. The truth is No, Betelgeuse is not expected to go nova this year. The timing of Betelgeuse’s potential supernova explosion remains uncertain, with estimates ranging from potentially happening in the next few decades to possibly taking up to a thousand years. While there have been fluctuations in Betelgeuse’s brightness and some studies suggesting it could be nearing the end of its life cycle, there is no definitive timeline for when it will explode as a supernova. Therefore, the idea that Betelgeuse will go nova this year is not correct based on current scientific understanding.
🌞 Betelgeuse is around 700 light-years away, so if it becomes Supernova now, to see this event & its impact on our planet we need to live here next 700 yrs!! So no need to worry of this event... just enjoy the rest of the video 😅😅😅
I’m ready for it….I will sit in my pretentious EV and know I am safe because the light and energy from the blast will recognise the Tesla as one of its own and go right over it. See…easy!!!
The we are not ready is stupid, ofc we’re ready, it’s just pretty light in the sky for us, way too far to actually cause any danger to us. lol I hate when people try to make space sound like it’s an impending doom, it’s not, every day supernovas occur, they’re just so far away we can’t see them with the naked eye. This literally happens every single day.
Ok… I just heard it exploded. Between the years 2424 and 2624 the earth shall be able to catch the light io it happening. (It hasn’t exploded- that we know of)
Remember, the idea that red giants go supernova remains an unproven hypothesis based upon unproven theories of stellar evolution and computer models. I’m not saying it’s wrong, just that we don’t know it’s right. There are alternative theories.
None of us right now would exist. If we did (maybe) witness it, we would be perfectly fine. Would see a bright light show which would be spectacular and would go down in the history books.
If we see Betelgeuse go supernova now, it actually happened roughly 500 years ago. 🙂

Um, when something happens now, that's called now. Effects wouldn't happen for a long time. But still, when they happen it'll still be now at that time.
Jeffery Epstein didn’t kill himself.
When faced, it's now. Probably good :)
Awesome comment!!! Eloquently brief. And yet profoundly deep!!!! ☮️☮️☮️
How soon is now?
Before working in astrophysics were you the voice of Huckleberry Hound? That would be so cool
"What Would Happen If Betelgeuse Burst Right Now?"
Absolutely NOTHING to us, at least not until 642.5 years from "right now".
when you have black holes and neutron collisions eclipsing its host galaxy by folds of magnitude it truly puts into perspective our tiny little star in how easily life can be extinguished by such an explosion.
"now" in astronomy means mostly our lokal time when we know or see it.
If it exploded just now, what would happen to the earth? Nothing right now! Betelgeuse is some distance from us, Astronomers suggest 422 +/- lights, but the distance is debatable. Some astronomers suggest that the earth is too far from us but honestly that can be debatable. Let’s say it did blow and it has since gone supernova, we will not know for 500 years. However I saw a story about Polaris the north star, that star is acting up. But if we were much closer, better pray….
God make this earth for everyone to enjoy life i think I , my kid and My love and other peoples to has the right to study all enjoy life am now 43 years old i want to say that even want learn how to bake bakery or enjoy swimming was to difficult for me i want to study master degree also to difficult for me i know everything what happen to my kids and her mom and other people got bully my love also got bully all that happen to my life do u think I want to stay on this earth . it enough for me i dont want my kids her mom to crying with non sense thing . Everyone was not happy with this situation. i love my kids and my Love as you all l
It might have already gone supernova but since it's about 640 light years away, we wouldn't see its light image for (640 - x) years. x equals the distance in light years the supernova light image has already traveled in the vastness of space.
If Betelgeuse went supernova today, we wouldn’t see it until about 640 years from now.
For some reason I always trust the British accent for narrating space/scientific videos over the American....
Not just “American accent” BUT THE ACCENT FROM THE SOUTHERN STATES. IT IS INHERENTLY ANTI-INTELLECTUAL, AND SLOVENLY. THE PRODUCERS OF THIS PROGRAM SHOULD NEVER HAVE ALLOWED THIS DISTRACTING NARRATOR.
Wow racist much?
Neither British nor American are a race. @@troyholdenvoices
That's a very scientific approach!
Haven't watched this channel in a minute and this new voice is very disconcerting and I don't like it much.
Edit: I've never watched this channel before-- I thought this was a 'What If' video... 😳🤷♀️
Just a cool light show. Since the star is some 650 light years from earth, plenty far enough outside the "blast radius". If it went off in the sky now, it actually happened over 6.5 centuries ago. Food for thought.😊
There will be a bright light in the night sky. There will be a brilliant light show for anyone here to see. Over a period of months to a few years it will gradually fade from view. Beyond that, we are in no danger from Bettalguese.
Exactly it's too far to pose a serious danger for Earth. If it blew within 20 lightyears we would not be so lucky.
Just don’t say it three times! 😅
Nothing! Nothing would happen...we wouldn't know for another 642.5 years. (It's 642.5 lightyears away)
It would take radiation traveling at the speed of light to reach us from Betelguise exploding about 752 light years. Any blast debris would take thousands of years to reach Earth.
IF you came here to find out about Betelgeuse this video contains 16 minutes of useless fluff padding. Skip to ~16 minutes if you don't want a long, repetitive lecture on supernovae. Even then you're going to have to sit through even more repetition and probably won't find out anything useful. This would appear to be one of those AI generated videos that are now plaguing the information age.
If it exploded this very second i understand that we will not see it for many years to come due to the massive distance light has to travel in order for us to see it. But could the JWST see it fairly soon after it actually exploded due to it being able to look extremely long distances?
You know it right that it will be happen this coming soon . as You say you are not ready. it not a joke Please be prepared it
my time to go back home already. This Earth might not suitable for me my love my kids i love my kids and love we all are to dangerous to stay on this earth i dont want myself , my kids ,my love to get bully anymore i want to stay in peace much more what is happento my kids me and my L
0:19 Now for who, us, Betelgeuse, or the Andromeda galaxy? Now, like your mama, is (a) relative.
A leading astrophysicist has said that we MIGHT see this with binoculars...maybe!
Not true cause if time is irrelevant in perspective to t speed of light. Then light would already b present no matter how far away. In my opinion
Well, right now as others pointed out Nothing! And By The Way, stop calling this star Beetle Juice,
It is called Betelgeuse,
You don't call the Polar Star Polystar do you?
So call this star by it's right cataloger star name please.
The Red Super Giant is about 580 to 600 light years away in Orion, So even if it went up now it would be 580 to 600 years if the
blast wave was going at light speed before it even got here in the Sol System. and even then no problems as by that time the wave would have been almost nothing in strength.
But since the blast wave be most likely only going at the most 10% of light speed it would take Thousands of years to get to our star system.
And any Neutron star or Black Hole left after the Super Nova would also be so far from us those too would be no problem.
So no no problems for our future humans. Since none of the possible Giant Stars out there that can go Super Nova are anywhere nearby us, We live in a stable part of the Galaxy.
If We don't then we would not be here alive like we are.
Need a medium for there to be a "blast wave." This is space, and gravity waves won't hurt you.
You're more at risk from the narrator throwing empty PBR bottles than this star going nova..
no it isn't
I love my kids my Love as you all Love ur kids and Love if this case happen to your Family it normal right.
If it explores right now, it will hit the earth in 500 years time and we will be long gone by then and flying around in space ships
It's so fascinating how we haven't even really left our own backyard yet we already know this much about the life and death of certain objects across the cosmos. It's truly impressive.
In answer to the title question, as far as we are concerned, not a lot. Because even light takes time to travel the vast distance, it would take a number of years for that light to reach us. So, Betelgeuse could explode now, and we wouldn't see the light of it until it reached us...
As for the tag, 'We're not ready!', we don't have to be. Betelgeuse is too far away from us for any harmful effects to reach us. At best we'd have a second bright light in our sky during the day, but that's about it. That and the fact that the constellation Orion will forever be missing a key component, that is.
Depends. Gamma-ray bursts are dangerous much farther away than only 600 light-years, which is this star's maximum distance. If the burst is pointed at where our general direction will be (400-600 years in the future) there may be trouble.
When it happens millions of years from now, it will STILL be now at that time
@@brianhammer5107 Yeah, but the chances of this happening are practically non-existent.
By "now" they mean when we see it happening.
@@brianhammer5107 You still missed the point. Carolyn is pointing out that the whole "we're not ready" is click baity and she would be 100% correct. Even if a GRB was produced by Betelgeuse going supernova and somehow pointed directly at us what in the world are you, or the video maker, suggesting we can do to "be ready" for it? Or are you suggesting that everyone make a "bomb shelter" underground made with thick lead walls in the super rare chance that not only does that supernova happen but also makes a GRB pointed directly at us?
Shouldn't we be able to witness countless supernovas at all times due to the sheer volume of stars out there?
724 light-years away from Earth. We're safe, completely safe.
Obviously you think betelgeuse is a balloon
Betelgeuse too far away to cause us any harm. It will just be very interesting to see.
You kidding? We aren't ready if it freezes, and a water pipe bursts.
It's 2 months later, and watching it happening live online now
Why dies the narrator say type "eye" a and "eye" other letters, but when he speaks of Type II suoernova, he then switches to numbers, saying two instead of double "eye" or "eye 👀 eye."
Strange.
Or supernova and supernov A. Makes me want to throw my phone
What he is actually saying is "supernovae" which is the plural of supernova. How he could know that and yet confuse Type1A supernova as being Type IA, I have no idea.@@zanetrukk
@@deedubya286I strongly suspect this is a text-to-speech bot reading a script. For me, the giveaway was the strong southern/texan accent, yet it pronounces "nuclear" correctly.
I wouldn’t worry about the spelling. It takes 600 years for the letters to get here….
We would know nothing for over 500 years since it's over 500 light years away.
Stop lying
At 650 light years away, nothing would happen except a very bright spot in the sky for a brief time.
Yep, we would be seeing something like a movie that was filmed six hundred some years prior.
If we witnessed Betelgeuse exploding now how long ago would it actually have happened, 700 to 800 light years ??
about 734 years (approx)
By "now" they mean "when we see it happening".
You are mixing up your terms. Light years is in reference to distance. Like Beverly said it would be measured in years distant not light years.
Van Gogh inadvertently captured a supernova in his painting “Starry Night”
Stop lying
If people could stop using "theory" when they actually mean "hypothesis", I would be so happy.
Nada no pasaría nada ya que lo que vaya a venir tarda unos años así que no pasa ahora nada
Great video first time seeing your channel in my feed liked and sub’d…. When bettlejuice does go nova do we know if there are any planets in its orbit and will we be able to detect the impact on them??? Many thanks for sharing 🍻👍
We wouldn’t know about it for quite some time. It’s that whole speed of light thingy. 👍
It may already have happened, and we could see it today.
The Multiverse🌏🌎🌍 🌌🌠🌌🌌🌌🌌🌌🌌🌌🌐🌐🌐🌐
"Burst"? It's a star, not a pimple.
The probability that supernovae themselves can induce detectable ripples in spacetime detectable in gravitational waves is pretty unlikely to occur and to be detectable would likely require a LIGO type observatory in space on a magnitude of close to the Earth - Moon orbit. Ninety-Five percent of the mass of a Super Nova stay relatively close to the star during the gravitational collapse of the star and resulting expulsion of the outer layers of the star resulting in much of the mass collapsed into a white dwarf but still gravitationally stable in essence with relatively much the same spacetime gravitational annealing in place but expanding only due to the materials shed.
If it happened right now, we wouldn't see it. Those in approximately 700 years will see it though
AWESOME!! Can't wait!!!
“THEE-A-TER”? WHERE IS THIS GUY FROM, ARKANSAS ( or similar states that tolerate such slovenly speech in their citizenry)? Just WHY DOES THIS PROGRAM HIRE A PERSON WITH SUCH AN ANTI-INTELLECTUAL ACCENT TO BE THEIR NARRATOR?? Don’T THEY KNOW THIC IRRITATING ACCENT IS DISTRACTING FROM THEIR MESSAGE. THEY’D BE BETTER OFF LETTING AN AI. OICD TO DO THE JOB. THIS WOULD BE LESS EXPENSIVE, AND BE ALIGNED WITH SCIENTIFIC NATURE OF THEIR SUBJECT. PLEASE!!
Look.. humanity just isn't doing ANYTHING correct. Would it really be a loss if something happened and we were annihilated? Seriously... We have people that think an imaginary guy lives in the clouds and blah blah blah.. its just mental. I'm ready for our demise.

Believe in none of what you hear, and only ½ of what you see. This was hilarious..I said out loud, talking to the screen throughout the video..."how do you know?".."that's not true" cracking up. I truly lost my breath laughing at "...and 10 billion years ago." Bwahaha Why'd Brittanica forget to include all this in our encyclopedia's? Cite your sources, or give your credentials. It's meaningless when it's coming from just a guy on UA-cam.
Are y'all old enough to have seen the movie/show/series where a kid had the unique ability to predict the future? And one day he said, "Our sun will supernova tomorrow" Everyone around him quipped back, "No! Not! It's only going to supernova because you said it will!" He told them, "No! It's fact! Our sun will go supernova tomorrow no matter what!" .....and, it did! I thought like the the others, that yes, it will happen only bc he said it would! Y'all hafta know that 'yes' there is that possibility only bc he said so! Anyway, I thought it quite an interesting conundrum that it would only happen bc 'he said so!"
^..^~~
Astronomers think that Betelgeuse is about 600 light years from Earth. That means if that star exploded NOW, we on Earth wouldn't see that until approximately 2624!!!!!!
Okay, so this was a very informative, well-produced video, BUT... you didn't answer the question of your title. You _could_ have. Why _didn't_ you?
Well if it happens --- It happens. Nothing we can do about it. That is the Universe for you.
Our planet is very fragile and anything can happen, Galaxies Colliding with each other, Star Super Novas Gamma bursts, Magnetic Poles flipping, Our own Sun solar Flares, Meteors striking the Earth, Mega Volcanos, etc - to name a few
Other than that, have a nice day.
Absolutely Nothing!!
Whatever could or, may, or already have happened to Betelgeuse we wouldn't know for at least 650 years after the event, admittedly. when we do see it, that light has traveled that distance, so any adverse effects in its wake will be right behind it. How could, would we know instantaneously?🤔
Unless you know of and believe in Quantum tunneling? A mind-blowing equation and subject that seems factually proven, possibly in use today!! A conversation for another day.😊
What would happen? Absolutely nothing is the answer. For starters, even if it was close enough to cause damage and exploded today, you will be long dead before it reached us. However it’s not close enough to do anything. Again, if it exploded today, we wouldn’t see it or know for another 650 to 700 years due to its distance. When you look at the star, you seeing it as it was that far in the past, not as it is now
I think the safe distance is 30 to 250 light years. So yeah nothing would happen..
It’s around 160 @@ThomasDowning-ud6fz
Though Beetleguese is unstable, it could last another 1.000 years, or even 10,000 years or 100,000 years before going Nova. Nobody can predict when it will explode .
The actual distance is not agreed upon by astronomers and astrophysicists. They're saying it could be anywhere from ~500 light years away to maybe ~850 with the actual number being somewhere in between. Either way it won't hurt the Earth's biosphere but it will be a great light show. I hope the wavefront arrives while I'm still alive to witness it.
edited to complain about the lack of a proper ending for the plural of supernova. English would have it be supernovas and Latin it would be supernovae. He's (the computer or narrator) is pronouncing it as though it's the Latin but the closed captioning is spelling it like the singular. LOL we know there's more than one...
We would understand if gravity and light travelled at the same speed. Light travels through space time. But gravity is space time.
So a supernova causes ripple in space time.
I understand current thinking has them the same speed. But maybe it isn’t. This star giving us a supernova will verify that.
We have an observation limit of the speed of light. In theory we cannot measure anything faster. If anything faster exists.
However just say it’s 500 years away by light. We may experience the gravity wave ripples at the same time, 20 years before or say 100 years before. I doubt it would be after.
Everything you see in the stars happened long, long ago. It’s ancient history. If anything happens to Betelgeuse, we won’t know it for 700 years unless it already happened. Who knows what the next minute brings……….🤔😳
Kuiper Belt? Bok globulars? 12,000 year repetition, in line with mass extinctions and rapid ice-age thereafter - now, where in our system could that energy come from? 🤔😊🖐🏻
Betelguese could have already went supernova, and we wouldn't know about it. It's over 600 light years away from Earth, so we are seeing light that was emitted by Betelguese 600 yrs ago. It could have exploded in the meantime, and we wouldn't see it until the light from it reaches Earth, sometime in the next 600 or so years.
Oh, another of these robotic voice videos talking about apocalyptic things. If you're lucky enough to see at night, you'll see an object almost as bright as the moon for a couple of seconds (think of it as having 2 moons momentarily). In daylight, maybe if you see at dawn or dusk, you'll see a fainter "moon", in between those hours, you might catch a glimpse if you know where to look with a telescope, depending on your local air pollution.
So no, no cataclysmic event, no Earth dying because ozone layer destruction, honestly, I'd be more worried about flossing too close to my gums than a supernova.
Sigh. As soon as I heard the narrator's accent I knew. Took a while until I heard the word that made me shudder. Fahrenheit. In 2024. The measurements of science is Metric. The fact that about 400 million people out of 8 billion still insist on using Freedumb units saddens me. Another 'Don't recommend channel'. These channels should be extinct.
I Believe, after a dream I had of volcanoes going off in Williamsburg pa, I awoke to walk out of the Mr Farley's area to see dark red black orange in the sky for about three seconds my heart beat so hard then I woke up but it was so real to me I have been studying cosmology and things that could possibly caused my dreams situation...I however do not know it was either beetleguese going supernova or Yellowstone going off all I know is I died in the mess my mind wouldn't lete believe anything different..it seemed like ifd be returning to dreams in real life ...note to my probation officer do not send me to rehab please ...or partial cuz shit is going to hit the fan especially around April may...no f*"#ing joke
Due to the distance Betelgeuse is from only our solar system sun. The image of it going boom today wouldn't get here for some 6.5 trillion of our current 24/7/365 day year's. IF we were to see it happen today. Meant that because of light travel's considerably faster and farther than any object's caused to be put into motion in a trajectory that could ever reach our solar system let alone our planet. Would have had to happen more than 6.5 trillion year's because the object's wouldn't be going to a degree as nearly as fast as the image is. Light is faster than sound, and sound is faster than any object who's trajector some 6.5 trillion year's away would eventually reach us.
There are concern's and there are resolve's to concern's. Though neither have to be actaully true, they do depend on being pitched correctly to the ignorant.
If Betelgeuse burst right now we would not know for 500 years. What is meant by "being ready," I have no idea. This I am sure of, politics would not let us "get ready," if there were something we could "get ready." I do not think there really is anything we can do.
The real world issue is when the results reach us. Comments about how long it takes to get here contribute nothing.
It might have already happened. Maybe hundreds of years ago, maybe days ago. So won’t know that answer until it arrives. At that point, the discussion is moot. The ONLY discussion of value is whether we are “hardened” enough, and prepared for the impact.
What Would Happen If Betelgeuse Burst Right Now ? pretty much nothing for the next 724 years, then we would see it or if we see the Super Nova right now, then Betelgeuse did blow up 724 years ago !
From my point of view, nothing. Maybe it already has but at approx 642.5 light years away...
I'll either be long gone or I'll go out and see something...
We live in a universe where objects are placed unbelievably vast distances apart, and the speed of light or rather the speed of electromagnetic radiation is such that it takes massive amounts of time for this radiation to travel between these sparsely spaced objects. So Beetlejuice is over 600 light years away from planet Earth. Anything that happens in current time at Betelgeuse will take over 600 years for us to observe it. It could have already had its supernova, but the electromagnetic radiation that we would observe of that event hasn't gotten here yet. Everything that we observe about our universe is in the past.
Well if it happens as I'm typing this post I'll have been dead over 600 years before anyone on earth knows about it so I don't really care. If it has happened 640 years ago and we're just finding out now since it's 640 light years away I doubt it will affect the earth at all. So again I don't really care.
The short answer is nothing. Mite be something interesting to see in the sky. Novaay, what's a Novaay. You say it correctly sometimes, other times ---. Anyway, it's trillions of miles away, no issues.
It could go supernova tomorrow and we wouldn't make no difference. For it to affect us today, it would've had to happen in the late middle ages (1300AD).
I've seen and heard everything in this sad little regurgitation on UA-cam over the last few years now. If this was a Jr. High school project I'd give it a *D-* for plagiarism.
Burst,,,,burst! ballons burst! Overripe fruit bursts! I'm not sure 'burst' describes a supernova very well? Just saying!
More sobering question is what would happen if a beautiful, yet failed human experiment on a a tiny planet named earth. Were to multiply insaneky, practice dividing and substracting one anither to an art form over thousands of years. Crawling across the planets face, devouring their only home..fubar. oh, shit..that us what has actually occured. In the end so few get ut while the rest if us pretend and do the same sames.
They are telling us that Betelgeuse will go nova this year. The truth is
No, Betelgeuse is not expected to go nova this year. The timing of Betelgeuse’s potential supernova explosion remains uncertain, with estimates ranging from potentially happening in the next few decades to possibly taking up to a thousand years. While there have been fluctuations in Betelgeuse’s brightness and some studies suggesting it could be nearing the end of its life cycle, there is no definitive timeline for when it will explode as a supernova. Therefore, the idea that Betelgeuse will go nova this year is not correct based on current scientific understanding.
🌞 Betelgeuse is around 700 light-years away, so if it becomes Supernova now, to see this event & its impact on our planet we need to live here next 700 yrs!! So no need to worry of this event... just enjoy the rest of the video 😅😅😅
No. Most anyone can could to 3000. That's the approximate number of twinkling ⭐⭐ one can see in the darkest of night skies. Not countless at all.
I’m ready for it….I will sit in my pretentious EV and know I am safe because the light and energy from the blast will recognise
the Tesla as one of its own and go right over it. See…easy!!!
If it exploded NOW it will be approx' 640 years before people see it, and I and you and every human on this Earth now won't be around to see it.
The we are not ready is stupid, ofc we’re ready, it’s just pretty light in the sky for us, way too far to actually cause any danger to us. lol I hate when people try to make space sound like it’s an impending doom, it’s not, every day supernovas occur, they’re just so far away we can’t see them with the naked eye. This literally happens every single day.
o to 19 minutes in this video and still NO answer to, "What Would Happen If Betelgeuse Burst Right Now?".....
Ok… I just heard it exploded. Between the years 2424 and 2624 the earth shall be able to catch the light io it happening. (It hasn’t exploded- that we know of)
Remember, the idea that red giants go supernova remains an unproven hypothesis based upon unproven theories of stellar evolution and computer models. I’m not saying it’s wrong, just that we don’t know it’s right. There are alternative theories.
It's deja Vu In a dream which sent me from 2019 to God knows when ...who do I say this too besides UA-cam people right?
None of us right now would exist. If we did (maybe) witness it, we would be perfectly fine. Would see a bright light show which would be spectacular and would go down in the history books.
