Remember people, Betelgeuse is like 500 ly away so when we do see it explode, like if it does today, it means it really exploded back in the 1520s!!

​@Gabriel frost i guess what u see was from the past, around 500/600 yrs ago idk

absolutely incorrect, 1 light year means the distance it takes light to travel in one year hence the name "light year". That being said whenever a star explodes light years away it would take millions of years for humans to see. Depending on distance we may never even see it at all because there are hypothesis that the universe is still expanding and perhaps accelerating still, meaning if something is expanding at a faster rate than light travels, that light will never reach some places.

In a simplistic way, that is true, but if one assumes that time is NOT linear, that everything exists in a non-linear (simultaneous) space time continuum, then it is hard to actually define the exact period that the star exploded, relative to our earth time..

@Mat Lenaghan are you sure that it isn't science?

The irony of a star named Beetlejuice that hasn't blown up three times is actually perfect

Hasn't yet because it hasn't been able to trade that ticket with another with a smaller number yet...

🤣🤣

HHAHAHAHAH

Pun intended I believe

@yitz28 🤣😂🤣 thank you dawg I needed that!

The only star we need to be worried about at the moment is the one we see rising every morning

@E’Zi I'd trust a scientist (in his/her specialty) before you. Why? Look at reality. Show a physics pathway for the Sun to go supernova two days from now. Do you even know what a supernova is? Hint: It ain't an unstable bomb.

@Mini TG Actually, no. Another part of stellar physics is stars get hotter over time. In less than a billion years, our star will have cooked our planet to an over done/burnt level.

@CasualCatAnimates Many other things will wipe out the current life on earth several times, with reemergence of civilization, several thousand times, before that final day 4 billion years in future.

Basically yes, but the effects of a supernova about 100 light years away could pretty much wipe out earth life as we know it. Not that knowing about it can help us prevent it in any way, but at least we can go out with a bang. LOL

@E’Zi nahh man, the sun is one of the most stable stars we know, it won't explode unless something absolutely 'astronomical' happens, which is a chance next to zero for the foreseeable future.

I fact checked this on just about every website on the internet that mentions Pegasi. Nothing at all mentions ANYTHING about its supernova being harmful in any way whatsoever. There's even an episode of NOVA mentioning how it will be an amazing sight in the night sky-- and that's about it. Disappointing because I'd love to be able to watch videos like this and believe that I'm actually learning something.

Besides, are Betelgeuze and IK Pegasi even on the same side of Earth ? If IK Pegasi is somewhat to the side or even roughly on the opposing side to Betelgeuze there would be no way Betelgeuzes explosion would push IK Pegasi closer to Earth.

A super nova would need to be closer than 25 LY to be dangerous.

This guy in the video whining like he`s about to cry is getting old on the internet.

You are right, this channel's content is mostly clickbait

@I think Even channels that give good information do this. And yes, very annoying and dishonest.

The odds against this happening are truly 'astronomical.'

🤣

Rivelazioni

Buh Dum...Tissssssh.

😂

So, the only “update” (by definition only) is that BG shoulda exploded 3 times already. The rest is a description of BG and Pegasus exploding.

thanx for savin me 11 minutes

This channel has some of the most shameless misleading-alarmist titles and clickbaity thumbnails that I have ever seen. The fact that Ridddle pretends to be a science channel is insulting. This guy only cares about clicks.

@Norse Texan yes it’s definitely exploded. We just can’t see it yet.

@Jetpond mmm… not quite. It “tricked” the viewing astronomers with its dim and bright activity twice. Though I’m sure it’s probably already popped by now. You’re definitely right that it hasn’t reached us yet.

Interesting, but why should we imagine that these two unrelated stars would explode simultaneously? Also, should it not be possible that Betelgeuse may have already gone supernova, only we have yet to see light from the explosion. and may not see it for several centuries more?

Since Pegasi A and B is a binary star system and Pegasi B is a white dwarf that would be a Type 1A Supernova because the white dwarf will cause the explosion after siphoning off the gasses from Pegasi A, Betelgeuse will be a type 2 supernova in which the core collapses after it starts converting atoms into iron.

@bdr32965just a question. But how is your opinion any different from a factual standpoint than the video. There is no factual hard evidence of the effects of a star going supernova close enough to see or feel the effects of it. In fact, only supernovas recorded where thousands and thousands of light years away which is physically impossible to detect the distance the effects were. All astronomy is best guess. But the video was well put together

@Cunnuk thank you I was literally laughing at this video. Umm yah, its waaaay far away and we wouldnt be here by the time it got here which would be very little energy at all.

@Cunnuk Yeah, it's clickbaity as hell. It's just that the guy you replied to, like many of us, learn things on YouTube by clicking on videos ike this. We're not uneducated. We educate ourselves. Of course, it helps to know that both stars are well outside the lethal zone for Earth. I was personally looking forward to the Betelgeuse light show.

@Herbie Goes Bananas As far as the clickbait comment goes, this video is nothing more than fear-mongering Neither of these 2 stars poses any threat to earth when they go supernova. If humans are still around and have not wiped themselves out by then. They'll provide them with an excellent light show when they do.

@bdr32965 Agreed. This narrator says "what if" a lot.

Pegasi is 150 ly away from us, Betelgeuse is 645 ly from us. From what I've heard for a supernova to hit Earth it would have to be within 50 ly to have an effect. Also riddle shows a picture with a straight line between earth Ik pegasi and Betelgeuse, what's the chances that there's an exact line between these star? And what is the odds of them blowing up at the same time? Also if they exploded same time the light from ik pegasi would reach earth 500 years before the light from Betelgeuse.

@reload north what does that have to do with this comment

@Assalam Azeem no, only if we are within 50 light years of it

earth still be affected by Betelgeuse supernova shock wave if not by radiation

How long does it take to travel 600 light years? 22 million years Since one light year is the equivalent nearly six trillion miles, it would take 22 million years to travel 600 light years on a space shuttle and visit Kepler 22-b with our current technology.

The odds that BOTH stars go supernova simultaneously, or even within the same century for that matter, are beyond infinitesimal...

Math is a bit off on the size shrinkage since 1993. Dropping down to 9.3 AU would mean 9.3 times the orbit of earth in relation to the sun. So it wouldn’t be the size of earths orbit, it would be 9.3 earth orbits. Still love your vids and they’re still awesome 👏🏽 👌🏽

Is it weird that I love to see this destructive boom?

We are all ready to see the sky being lit up even at night by those exploding demise

@Abram Little wtf do u mean by that? if u mean life on earth or the earth itself then, no, the solar system won't be affected, both stars mentioned are too far away and IK pegasi is actually moving away from us

It would change the consciousness of the entire planet if it exploded

Your not the only one either

I personally hope to see a killanova

What if there’s a Dyson sphere around Betelgeuse and every time it goes dim it’s bc an advanced civilization is using its energy 😳🫢

I'm going to be honest here, his videos are great and all but the soundtracks this guy uses makes his videos awesome

I had been noticing over the past few years that Betellgeuse has looked much redder than previous.

if it ever happened you'd have to set up camp and get the event burnt into your soul, as to take it with you, such a beautiful sight.

Just like woody harrillson in 2012 at Yellowstone lmao

100% agree

It could have by now, we're just waiting for the light to reach us to tell/show us so. In all likelihood though it's probably still on its way to supernova...just not quite there yet.

There is some misinformation with the presentation of IK Pegasi here; IK Pegasi A is an A-class main sequence star, and IK Pegasi B is a white dwarf. The graphic used to describe IK Pegasi A and B in the time index @6:44 are in actuality size comparisons of IK Peg A vs. Sol (the Sun). IK Pegasi A will not transition into a red giant anytime soon, and if, and a BIG IF here; IF IK Peg A does transition into a red giant and goes supernova, Sol would have moved so far out of range. Remember that Sol and every star in the Milky Way are still traveling, and will not be in their same positions when you're talking about a time table of millions of years.

Who ever said Beetlejuice would be dangerous? It would be an awesome light show. It's one of the brightest stars in the night sky so that exploding will be immaculate

And that's the last scene of the life...

@Chomusuke well this can be a nice learning lesson for you. Don't just take anything you hear on the internet for the truth. It takes 1 3 second Google search to know and then when you come across videos like this you can call bs

@Mini TG it will be as bright as bright as the moon and last for months.

The click baiters say it will light your hair on fire "alarming, terrifying"

And you’ll only enjoy it for a hour

I love you guys so much, keep it up with these knowledgeable informational videos

You're being sarcastic...right? I hope so

The fact that scientists were wrong about Betelgeuse makes me worry that our sun can start to swell in size much sooner than expected

Different cases. Betelgeuse is an anomaly very far away , whereas the sun is constantly studied and monitored. Following standard stellar predictions which we know have been true countless times , it would take roughly 5 billion years for it to enter its red giant phase.

It is unlikely that a supernova in the Pegasus constellation would pose a direct threat to Earth. The closest star in Pegasus that has a chance of going supernova, called HR 8752, is estimated to be over 800 light-years away. While a supernova explosion would release a huge amount of energy, it would take hundreds or thousands of years for the effects to reach Earth, and they would likely be limited to a relatively small increase in cosmic radiation.

Ahh yes another great piece of content from the legend himself

I'd just be like "Nah bro, I ain't scared by a bit of fire...and radiation".

The star is alive and they caught it breathing. No mystery.

Betelgeuse knows we are watching and it is playing the shell game with us.

Exactly right in this video. Our brightest have no idea how to measure these events. Space is tricky business!

Our own star system has an extensive ort-cloud surrounding it that contains many times more mass than all that is found within the all the planet's orbital dimension plane. That cloud also conforms as a bubble around the east/west orbital plane of the planets, being somewhat closer around the northern and southern spheres of that bubble. This cloud bubble is sustained by the magnetically enhanced gravity of our sun. Just as the Earth's ozone layer protects the surface of our planet from solar radiation from the Sun, our star's ort-cloud is able to absorb and buffer radiation bursts from ejecta sources much further away from that cloud's outer-gravity sustained boundary. Sources such as exploding stars.

If a star goes Supernova, I want to know about it; even if it's a thousand trillion miles away.

Betelgeuse is a red supergiant star located in the Orion constellation, approximately 640 light-years from Earth. While a supernova in Betelgeuse would be an impressive sight, it is not expected to pose a direct threat to Earth. The shockwave from the explosion would likely not be strong enough to have any significant effect on our planet, and the burst of high-energy radiation would be mostly absorbed by the thick layers of gas and dust in the interstellar medium. However, a close supernova could have a small impact on our ozone layer, potentially leading to a small increase in the amount of cosmic radiation reaching the surface of the Earth.

None of these stars can harm us. They are very very very far away.

Even when it does go supernova we are out of range of any possible damage

Maybe the sun gods of the Mayas sent their warnings correctly and both Betelgeuse and IK Pegasi went supernovae in 2012 :]

I can't explain why Beetlejuice hasn't exploded when it hasn't been said to have been due to do it for three times now, the scientist forgot to say Beetlejuice x3 😂

not just that , worry about our own stars micro novae if we get that and it could in the near future. now i think beetles went micro and ours is due again

So we don’t really know how large the star is because of how “bright” the gas is and the star is itself, it could essentially be the size of a car for all we know so far…

If it was the size of a car, it either wouldn’t be a star or it would be a black hole.

All the density is highly dangerous

If that happens, hopefully I will not be incarnated into that lifetime.

Hi riddle I really love your videos, they are very informative and fun. I watch these in my free time

@Jim Herold thanks for your opinion

@Lanting Farming why don't have work

@Lanting Farming rip

Ok... I may only be a handsome & humble meme scientist but if theres dust just hanging around a sun then we should make our ships outta that sh*t

the mentioning of a potentially life-threatening supernova is somewhat preety cool.

I am so ready 🥰 for this 🔍 to happen 🤔 I hope in our life time

If we see it in our lifetime, it actually exploded 500 years ago.

If Pegasus will explode tomorrow we will notice only the radiation emission visible uv and gamma but the blast of star material will likely move much slower and reach us in hundreds even thousands of years

"Those who survive with a nuclear winter" part, say the Mariana Trench was on the EXACT opposite side of Earth where this happened, what would happen? Complete chaos? Nothing? (Challenger Deep?)

The shockwave it very unlikely to move a star 120 light years, let alone them even being close in the sky.

@Williams Ville it takes as many years as far away it is in light years.

How long does its light take to get to us? If we happen to see the explosion, it would have happened eons ago.

I forgot about the Keyboard Astrophysicists that frequent the comment section. Thanks for letting us know.

Thank god someone else is the comment section has a brain

It would have been very interesting to witness the explosion of Betelgeuse million years ago ang it became visible to earth after so many years from explosion

Millions?

The crazy thing is - when we finally see it go - it would have happened a long time ago and the light is just reaching us now. For all we know, it happened a 500 years ago and we still haven't seen it yet.

@covid1234 😂😂 haven't laughed this hard at ignorance in a bit

@fj9ae you do realize it's so far away that even if it went supernova, it wouldn't even affect us

we would of felt its effects

@covid1234 bro light doesn't instantly travel

@covid1234 I'm done with you🤡

I'd do my day as though it wasn't even happening

*Finally. Time To Be At Peace With My Eternal Creator🕊*

And I realized that almost every stars and galaxies are moving away :-D

Noone has said that we should fear Betelgeuse exploding. It is a safe distance away for us to watch for research on how red giants behave.

@Sam-Miner I can't see the logic behind saying that Betelgeuse is that far away. It is confirmation bias. Not science.

@Slick Willie because stars are extremely bright. literally do your research. also a supernova is also INCREDIBLY BRIGHT. i think you underestimate how powerful a star is. Yes its still a pinpoint of light because of how far away it is , but any photons that do reach you portray how bright it really is.

@evadecaptcha Thanks. I edited my post accordingly.

@evadecaptcha "The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth."

@Slick Willie It takes 9 minutes to travel at C from the sun to Earth. Not 8 seconds.

i love your content its super intriguing and your voice is so soothing

IK Pegasi A would probably take a while, as it would have to evolve into the red giant stage, which takes a while. Than IK Pegasi B would have to accrete the mass until it hit the Chandrasekhar Limit, which is 1.4 solar masses, before it detonates. Betelgeuse is much further along, and will probably go sooner than later. Betelgeuse, externally, is in it's final form before it blows. We just don't know what's going on inside, with the various layers of its core, which could give us a more accurate picture to how close it is to detonating.

great video!, thanks for anxiety too

Cant believe I missed this one !

He could of basically said, "pick any star in the sky, it could possibly explode in the next 500 million years!"

3:28 sounds like Beetlejuice just needed to let out a really big fart

Damn. This channel hits way too hard. I’ll tap out for now.

@Brad Vincent This channel posts a lot of fake stuff. I don't recommend watching it. I don't know how youtube hasn't taken down it already

I’m surprised I didn’t catch on until 5mil other people did but maybe this one just isn’t for me then.

The minimum distance at which a supernova could pose a direct threat to Earth is not well established and is the subject of ongoing research. However, based on current understanding, it is estimated that a supernova would need to be within a few tens of light-years from Earth to potentially have a significant impact. At such distances, the explosion would release a large amount of high-energy radiation, including gamma rays and cosmic rays, which could penetrate the Earth's atmosphere and magnetic field. However, it is important to note that even in this scenario, the overall risk to life on Earth would still be relatively low, as the Earth's magnetic field and atmosphere would provide some protection. It is also very unlikely that a supernova would occur so close to Earth.

A lot has to fall into place or that doomsday scenario.

If Betelgeuse is in the process of ‘exploding’ we on Terra are looking at the light from that star from the year c. 1382 - the year the English city of Winchester was burn’d to the ground by the French—and the same year Axatacatl (Monteczuma’s father) was born — so we are a little late seeing very old stale-data

Were this to happen...we're basically fucked @ our current level of tech development. Getting the popcorn & be like Woody Harrelson in 2012 wouldn't be such a bad way to go...

betelgeuse not exploding in the next 100,000 years is the most heartbreaking news i can receive today

@Sam Del Valle maybe we can? We can't know right?

@Delaney Watkins yes, but not seeing it in our lifetime is the sad part

Nah it’s most likely already gone. We just can’t see it yet.

So, affectively what you're saying is that it's bad enough if just one of those stars goes supernova but if they both go at the same time, then it would be the interstellar equivalent of a perfect storm here on Earth, only there won't be much left in the way of humanity or anything else for that matter afterward.

Riddle is equivalent to astrophysics Zerohedge.

I know why they don't tell us: there is nothing we can do about it 🤭 so no wide spread panic

Ir wasn't a Supernova explosion that destroyed the dinosaurs, it was a comet that impacted in modern day Mexico

I would definetly eat popcorn and wait while it happens, I mean what can we do at that point. We die = We die We live = We suffer for years until we die

IK pegasai is well outside the damage zone for earth.

Betelgeuse may have already exploded. It's 650 light-years away. Hell, it could have exploded when Shakespeare was writing Hamlet.

Beetlejuice is likely gonna be around longer then we think, we will see alot of fake outs and ha got ya moments for a long time. Like a silly old man, he enjoys the humor

Shy is it imperative that it explode now? Because i want to live long enough to see it!

welp when pegasi finally goes supernova i will be a few hundred million years old, so i dont think im gonna hold my breath waiting on that one either.

Betelgeuse could have gone supernova already. But we wouldn't know it for 600 years. Being that it's 600 light years away.

It's those sandworms you need to worry about.

Whoa! Sandworms? You hate 'em, right?

The spice must flow.

We dont talk about the sandworms.

I have been watching stars and constellations with naked eye since 1980s. Beetlejuice does look evidently smaller nowadays compared to 40yrs ago.

even if betelgeuse did explode tomorrow, when would we see it? given the amount of time it takes for light to travel, how long would it take for us to see the supernova?

@User 101 ...

Flash

What if a nearby more advanced civilization is actually delaying or stopping the explosion of Betelgeuse.. hmm 🤔

Time to stock up on popcorn for that day.

when or if the planet does get destroyed im all about being here when it does ... if everything is getting destroyed i want to witness it

Betelgeuse may have already exploded if it's energy could reach us, which were told it can't we wouldn't know about it until the destructive waves reaches Earth and with a supernova we wouldn't be about to worry about it

@PianoMan 2018 we often see this is Hollywood like 2012 great film the Neutrinos have Mutated no longer Neutrinos are the then ???

@mic stone 💯 (or they’ll keep it a secret.)

@PianoMan 2018 I've heard it's too far to hurt us, but think some background cosmic ray's may be detectable especially from space based detecting satellite receiver's, maybe they could tell us when that time might be

@The Grey Wanderer Uh electromagnetic radiation travels at the speed of light there bud. Or more accurately, light travels at the speed of electromagnetic radiation, of which it is a subset. In other words, the effects of a super-nova induced gamma ray burst would appear to us as if the star exploded and instantly ignited and burned away the ozone, thus resulting in apocalyptic conditions here. Thankfully, the odds of actually being struck by a gamma ray burst are astronomical. Unfortunately, even the most astronomical odds become virtual certainty over long enough periods of time. So it is possible.

The amount we know about the universe fits in a smart car. what we know about the oceans fits in a shoebox.

@Gopherchucks than go ahead and explain it for me genius

@fj9ae It wouldn't to someone that thinks they know everything.

that makes 0 sense

Imagine if UY Scuti is on Proxima Centauri's position and it explodes ☠️

How are we going to get out of the way of a supernova ,we’re a closed world.

If Betelgeuse explode now, Procyon and Sirius will be sad.

Just be with our loved ones…

"the waffle house has found it's new host"

More than likely scientists are keeping quiet about the supernova, because they don't want to create a panic

No. Its because it literally isnt going supernova in our lifetime. And even if it was , we are way out of the danger zone.

The fact is it might have exploded long ago. A lot of the stars we see in the night sky don't actually even exist anymore, we still see them simply because the light from them is still traveling towards us long after the star has gone because of the distance from the earth.

technically speaking the stars that make up the constellations , almost all still do exist since they are mostly under 1000 light years away. As for distant galaxies however , that is true.

It’s really crazy to think about.

I guess I will have 4,000 years from the time it happens to decide what to do.

A supernova exploding 30 light-years away from Earth would be a significant event, but it would not pose an immediate threat to our planet. The explosion would release a huge amount of high-energy radiation, including gamma rays and cosmic rays, which would travel through space at the speed of light. Some of this radiation could reach Earth, but it would be mostly absorbed by the Earth's atmosphere and magnetic field, limiting its impact on the surface. The shockwave from the explosion would take several decades to reach Earth, and it is unlikely to cause any significant harm. However, a close supernova could have a small impact on our ozone layer, potentially leading to a small increase in the amount of cosmic radiation reaching the surface of the Earth.

You said Betelgeuse so many times I kept waiting for Michael Keaton to appear in my living-room....

They keep quiet about our own Sun's micronovas.

They = Thousands and thousands of government, independent, hobbyist, student scientists....

Yes...!

Actually, most scientists never predicted it was going to nova in the immediate future. It will nova, in the next 10’s of thousands of years.

Things can't be 4x closer. Closeness isn't a unit of measure. Things can be 1/4 the distance. But not 4x closer.

Wait how many light years is this away—I thought things we see already happened like 1000 yrs ago

Yes, if the things you are looking at are 1000 light years away.

If Betelgeuse went supernova right now, we would never see it. Because it's 642 lightyears away. It will take at minimum 642 years before humans can see a change in its size and brightness.

i sometimes wonder where this guy gets his info from. like just cause one part of the ozone layer gets damaged doesn't mean the rest of it also just crumbles

Fun drinking game: Drink every time a Ridddle video uses the word "moreover" in their narration

And the Bible talks about the stars falling from the sky and I sure as hell believe it will come to pass

Let's all cross our fingers for IK Pegasi!!

And since Kepler telescope we will be able to see so much farther but we need to turn a huge telescope into deep space where we cannot see right now so we are able to see back in time even further
