Watch Stars Move Crazy Fast Around Supermassive Black Hole
Вставка
- Опубліковано 30 вер 2024
- At the heart of our galaxy is Sagittarius A*, a supermassive black hole nearly four million times the mass of our sun. Its gravitational effects are quite intense due to its size, and the effects can be detected by looking at the stars in its immediate vicinity. A study, published in August 2020, examined the area surrounding Sagittarius A, looking for the tell-tale signs of stars.

Cosmoknowledge brings news from space.
We love you, explorers!
A massive object such as a star moving at 8% at speed of light... Thats terrifying
Indeed. And fast. 😄
A BIG star, several times the mass of the Sun. Whoops, get outta the way of that thing...
What surprises me is how do these stars stay together moving at this speed? And why don't they collide or will they at some point. Even in the slow motion video of the movement you can see them being pulled at by the black hole losing material.
@@umami0247 They are moving through nearly empty space, but yes these stars can be torn apart if they get closer to the black hole.
Can someone point me in the video where is that speed of ~23983km per sec (8%). Seems I missed it and cannot find it. Or was it the 8740km (~2.9%) ? If that's the case, yeah, I'm nitpiking, but I like exact data whenever possible when it comes to science. 2.91%, it's sill quite fast, don't get me wrong, I would be happy to travel that fast.
27,000 LY away. So, in reality, we are watching how these stars were orbiting Sagittarius A* 27,000yrs ago🤯
That's correct.
M87 black hole pic is 55 million old lol and this is 27,000
Yes.The sad reality of space.we are alaways looking into the distant past.
That’s crazy, human physics do not apply we must all take that into account.
Yes...but this time is very small in case of space events...so the observations made by the scientists won't have much change as the stars are right now
Watching this video from Atacama region itself is amazing. When I was teenager our school used to send us to visit TOLOLO and ESO observatories. I'm glad my country gets involved in the study of our universe.
That's really awesome. Thanks for sharing this. ❤
I visited there one time, Tololo as well as Gemini South, with the remarkable Vera Rubin Obervatory's LSST. It was some of the most incredible, and beautiful mountain-scapes I've ever seen, and it was a true shiver down the spine to be that close to, and get visit, these magnificent telescopes, many of whose discoveries we are so familiar with and in awe of. That you got to go there multiple times is a wonderful, and very special, opportunity and experience!! Very cool.
Imagine being on a planet around one of these stars
Haywire.
I’m not sure planets could even form or survive the tidal forces in such an extreme environment
@@quantumrobin4627 They would need to be in independent orbits, and could not orbit any of the stars unless they orbit extremely close to the stars.
@@TheReaverOfDarkness I would imagine there are a lot of stolen planets independently orbiting that behemoth.
Not to mention a vast number of lower mass stars, which would make up a far larger percentage than the more massive stars we can see.
Sag A* probably gobbles them like Maltesers.
@@skateboardingjesus4006 Yeah, it probably does!
We probably don't stand a chance of detecting the Earth-sized ones any time soon, but I bet we could find lower mass stars, even red or brown dwarfs perhaps, by checking for how they shift the orbit of higher mass stars on any close approach. But it'll probably be only a very tiny shift, as anything not in a basically stable orbit would most likely have been either ejected or swallowed up before we started looking!
At 0:35 "the fastest of the bunch, clocking in at 8% the speed of light. At 4:19 "record holder star S29" travelling 8740km/s. That is only 2.9% the speed of light. No mention of the star S4714, which is the star that is travelling the fastest at 8% the speed of light.
Yeah I noticed that too. One thing I've noticed about most of these "science" channels is that they botch things pretty badly and I assume just expect the viewer to not know any better. I don't know why they bother making science videos if they're so sloppy and don't understand what they're talking about and mostly imperfectly copying words others wrote.
It might be that they measured it at 8740 km/s, not at the closest (fastest) point. They could the use conservation of angular momentum to compute the maximum linear velocity when it does reach the closest point.
@@Natethesandman1 No, it is a different star (S4714, not S29) that has been measured at 8% the speed of light. You can look it up for yourself.
Here's a quote about it "Sagittarius A * located at a distance of approximately 27,000 light years from us. The mass of the black hole is so large that it allows the star S4714 to accelerate to 8% of the speed of light (about 24,000 kilometers per second) as it passes through the pericenter.
During the search, the star S300 was discovered, and it was also possible to observe behind the S29, which approached Sgr A * from 13 billion kilometers, accelerating to 8,740 kilometers per second. End of quote.
So, S4714's maximum velocity is 24,000km/s, while S29's maximum velocity is 8740km/s.
I can't give the link as it gets deleted by youtube (I tried).
Well I just unsubscribed after this comment
It’s very possible that they got the math wrong on the speed this star is moving at I don’t find it that disconcerting. We are human and with this amount of information on several stars it is possible they got some numbers mixed up again I’m not going to get jacked up over it.
I'd love to see a 360 video with our viewing point being just chilling on top of the black hole.
Seeing the stars swirl around would be so cool!
This channel is going to explode! Superb editing.
Oh, that's really great to hear. Thanks for these words of motivation. I appreciate it! ❤😌
If these stars that orbit so close started as a binary pair, and one was ejected would the star that got free have enough velocity to escape the galaxy? Are there individual stars roaming the intergalactic void? It's almost sad to think about; they would be homeless stars...
Yes, they become rogue stars, and they can escape the galaxy.
Kapteyn's Star is moving almost at escape velocity and will go well outside of the galaxy before coming back around. It is what's known as a halo star because it is not part of the galactic disk and instead belongs to the galactic halo. Almost all of the fastest stars we see are halo stars moving below escape velocity, but there is nothing stopping stars from getting boosted to even higher speeds. They just spend a lot less time here for us to see them when that happens.
The Barnard Star: Back in 1985, it was ~5.98 light years away from our Sun. By 2005, it was ~5.94 LY's away from our Sun.
That's ~11.9B miles per year, traversing ever closer to our Sun's position. If nothing changes its course, by the year 11,700AD, it will be around 3.8 LY from our Sun, making it the closest sun to our own.
Currently, Proxima Centauri --- one of the 3 stars of the Alpha Centauri system --- is the closest star to our Sun, at 4.22 LY away.
Gravity doesn't work in space. The astronauts are floating.
The most astonishing data I have learned about Sagittarius A• is that within 4.3 Light years of the black hole (The same distance from the Sun to Próxima Centauri) there are 1,000,000 stars!!! 1 million! This is not a place you want to visit.
Why not?
@@ivanpshenitcyn8242You might die, that's why.
Holy... Damn... I just found out theres a timelapse of the stars orbiting the black hole in a 20 year timelapse. Now just imagine what the James Webb Telescope could observe
Crazy right!?
WILL observe!! So exciting!
So many stars occupying such small space, and in great velocities. I wonder how many of them had crashed or gotten slingshot to the far side of the world
😌❤
Even in that relatively small volume, there is a lot of space for stars to whizz around. Besides, those stars are only the tiny minority you can see, because of their masses. There are far far more than them in there. The ones that are much more numerous, are too small to see.
A mad carousel of hyper-velocity celestial bodies.
They can't crash. The space is too large. In a sphere between our star and the closes one you can put all the stars from all the galaxies in the entire universe. It's unbelievable to think but it is true.
@@ps4games164 that's 4.3 light years in diameter so yeah, I can dig it!
And their companion planets don’t forget
If those stars are traveling at tremendous speeds while orbiting a smbh, does that make them younger than everything else in the galaxy or older?
Younger. A clock on one of those stars ticks slower than a clock on any other point in the galaxy
Depends on where the viewer is relative to those stars. To answer simply, it makes them the same age (assuming they all formed around the same time).
@@chrisr4220 but those are travelling much faster.
@@chrisr4220 Not true. The stars near the centre of galaxies are way younger than the once like our sun on the outer arms. We see maximum light at the center of the galaxy which are gases still have the ability to imitate star formation. Those gases are not on the outer arms of galaxies.
Imagine someone from other galaxy say this galaxy black hole is really mysterious
Crazy.
Makes me wonder if being on a planet going 8% the speed of light would feel different than going 67k mph on ours
In the book “ASCENSO, Civilization of the Humus” published on Amazon, a theory is proposed that unifies relativistic and quantum physics, supported by a mathematical and analytical calculation of the fine-structure constant (1/137) for the 3rd dimension and the other dimensions that make up the Universe. It includes parallel and mirror universes. It proposes a mathematical theory of how the multiverse should be structured and the action of dark matter and energy within it
Imagine if we could get an observatory array like this on the moon
That will happen sooner than we think.
The British accent lends an air of enlightened sophistication to the video without being overly pompous or pretentious. I like that! Thank you.🤗
Yayy! So kind of you! Thank you! ❤
I can't believe we saw a supermassive black hole 4 million times the mass of the sun, the master arranger of our whole galaxy, and named it Sagittarius A... that's kinda lame, ngl
Well, astronomers suck at names. 😄
@@Cosmoknowledge But fortunately their content is top-notch, this video is amazing
It’s incredible how black holes can toss supermassive objects like they’re nothing
Crazy.
Because they have mass more than those objects
This is what i watch in my free time! 😬
Well, you are spending your time just right, my friend. Thank you for watching this stuff. 😌❤
You ain't the only one Ak! Happy birthday Jesus and JWST!
First
❤
All props to the cameraman that survived the blackhole
She got a raise. 😂
Always one comedic genius who dredges up that tired joke
Definitely props to the photographer ! That is a patient person !
3:19
This footage is awesome
at that speed it could orbit earth once every ~4 seconds
Crazy right!?
I believe I know how penny feels, on the Big Bang Theory show.
This cluster containing sagittarius A* supermassive black hole and S stars orbiting holds a special place in my Astronomy loving brain. Not only are those stars orbiting at extremely high velocities, one of the stars orbital period and closest distance to the black hole is so so so so soooo hugeeeee.
It's amazing to observe this stuff.
@@Cosmoknowledge it sure is. Observing true magnificence from afar about which not much people are aware of.
The black hole accretion disc animation at 5:00 is completely wrong. Tsk. Tsk.
Thanks, i thought so
Just subscribed just now. Great video. Can’t wait to see more in the future.

Wao esto si vale aunque esté en inglés
Aprendo de paso
I hope none of these stars have planets with life
What part does time dilation play in these objects' apparent speed? I know that the speed of light is constant no matter what frame of reference you're in, but I was just wondering.
What we see from all stars are the effects of time dilation.
raum und zeit exestiert dort nicht.alles verschwindet bis auf etwas licht.
Virtually none. The formula for time dilation is sqrt(1-v^2/c^2). Try putting .03*c or .08*c into the value for v and prepare to be underwhelmed.
Even at 8% the speed of light, 2 clocks will only be off by about 1 second after 5 minutes.
@@medexamtoolscom alright so by that calculation if you're in a spaceship bound by the gravitational influence of the star going a 8% the speed of light and your rescue mission is not until next year, you will be 58 hours younger relative to the rest of the beings (living) at rest. that's a pretty significant change I think.
Gravity will be replaced by gravity plus later this year sounds funny out of context.
Wow!
Will the orbits decay enough that Sagittarius will swallow those stars or they will collide?
Eventually, probably.
This is amazing, I was 25 when the first black hole was discovered.
Awesome. 😌
@@Cosmoknowledge The things man has seen and done just in my lifetime is crazy. wish I could start over now.
Hopefully JWST will give us more detail views.
That telescope has so much to give.
Thumbnail of the year 😍✌🏼
Yayy!!! Thank you! 😍
still not as fast as the speed of post nut clarity hitting the brain
😄😄😄❤
Imagine that you are living in those mysterious object what do you feel 😢
Astrophysicist Andrea Ghez did this year's ago in 2000. It was on How The Universe Works.
I don't think there is any form of life that resists the forces that occur there. Both space-time and reality are completely broken there.
I think Superman himself would be in danger there xD
Indeed. 😄
And they come up with this baloney from looking at specks of light. Like grains of sand on a beach. Accuracy my prediction is 000000001%.
Sorry, but what's the matter with superspeed close to the Event Horizon of a Black Hole? The formulas tells that the closer to it, the slower the time. And, as fomulas says, any matter will reach the Event Horizon at an infinite time.
I cannot look at rocks on the bottom of the swimming pool and act like it's a black hole. Watch the one star jump an inch to the left instantly while the others don't. It could be a condition of space bending light and creating that entire scene. That's not a theory, because they don't want it to be. It's people, none of which are responsible for what they think. They are just "following" what they were told. Even the black hole images were drawn by creatively calibrating the image until it looked the way they wanted it to look. Man is devolving in intelligence. When you actually question things, they tend to fall apart.
Objects that massive moving at such unimaginable speeds is mind blowing. But they're probably nowhere near the largest or the fastest objects in the universe.
How the start’s developed a stable orbit under extreme condition. The answer simply 👉🏿ALLAH the creator is a sustainable all movement super Large start.
Who are these cartoons for? For kids 3 to 5? You don’t know what is underground, what’s inside the oceans, you don’t know what happened 300 years ago, you don’t know what a person is and you close yourself from viruses with a rag ... ha.ha.
So sad destiny star...
If that star has far distance of blackhole, they leads so many planets and asteroid...
But it has close distance of blackhole😂,so it is arrested by blackhole
😢
no free no kids😢
ALLAH creation is so beautiful and perfect might be the black hole spin 10,000,000 km/s
So the black hole is like a sun and some planets which are the stars there orbit the black hole.
But I guess the only difference between them is that a black hole doesn’t create energy to subjects going around it.
❤
Black holes pose no threat and those star are in no danger of falling in, they will simple orbit for ever, the same is true for galaxies with supermassive black holes, it is impossible for the black hole to effect anything beyond a certain radius
What kind of G’s would you feel as you swung around a massive black hole 8% light speed?
Or, since there is no "bending of space and time" perhaps it's orbiting a plasmoid.
Eject stars? Doesn't that mean an ejected star will be flying at high speed destroying everything in its path and not reduce speed due to vacuum?
All stars of a milky way and its galaxies in present univetse timeline are orbiting around a giant supper maasive black hole of a collappsed universe millions of trillion crore light years old ancient univetse which wholly ended in a mammoth supernovae ...
From such a big distance, if the stars are moving at the speed you have portrayed, it is amazing indeed. But where is the proof of this speed.
I'm so curious about what JWST gonna find regarding these kind of phenomenon. 🤔
It's gonna blow our minds away.
Wow, I didn't realize that it was that massive, You're a wonderful narrator Melissa, Thank you and everyone for the hard work that make this channel one of my favorite, Happy Holidays to all and I look forward to the next video. 🌎 🌲
Happy holidays to you, too, and thank you for the good words. ❤
@@Cosmoknowledge 11
If time dilation exists then how is it that stars move as fast around black holes? Do objects orbiting black holes fail to move as fast as it should?
all these science stuff is giving me anxiety
Appreciate the beauty of truth. 😌
@@Cosmoknowledge i watched the whole video :)
Скорость вращения звёзд вокруг своей оси строго ограничено и зависимо от размеров звезды. 0:15 вращение показано в ролике не возможно в принципе, ибо сила инерции, которое возникает в процессе такого вращения разорвёт звезду в клочья. *Удивительно другое, что учёные астрофизики, допускает подобную научную профанацию.*
It’s pronounced Sagittarius A Star (Sagittarius A*) 👌🏽
I hope they're going to put JWST's eyes toward this magnificence.
Indeed, they will at some point.
如果把黑洞和围绕它的高速恒星之真实空间比例标出来。黑洞，不过是一个引力中心而已。
Think of what's happening around Ton 618 yikes
Best images, space science has grown, improved, just the best subjects to study 📖. 💘 love it 😀, 😏😶wordless,no questions 🍎👽🛸😱🧐😎
So awesome to hear that. Thank you! 😌❤
全然ブラックホールに落ちへんやないか
Just wondering if these stars that are orbiting at ridiculous speeds near Sagittarius-A star have a solar system with them spinning at those incredable speeds. Can anyone else imagine a solar system spinning around a black hole at 8% the speed of light? Lol
Crazy right!?
Black star ra kokhono kokhono hole khele kalo rong dia ata stto..
This challenges western theories that black holes consume stars😢😢😢
Just don't get caught in it's path🤯
Indeed. 😄
Too much fantasy
There's nothing out there Only the watchers the heavens and stars
gravity will bring us all back together into one singularity at which point it will not longer be able to hold us together and it all starts again..
somthing is not right here if there is a black hole why those stars not fall inside ? it could be simply mass centre
When the video mentioned that the newly discovered stars had been given the names S4711 - S4715, I had a feeling there must have been scientists from Cologne involved. Simply hilarious.
🇨🇱 Shout out to Chile for all the telescope sites 🇨🇱
Saggitarius A star
❤
Why our milkyway black hole called a 🌟?
Gravity.
@@Cosmoknowledge what gravity? I never heard the term "star" being used for other galaxy's black hole.
@@sajiddawar000 It's was assigned the name "Sgr A*" because before it was confirmed to be a SMBH, it had been classified as an excited radio source at the center of the galaxy and in the constellation of Sagittarius.
simply citing velocities does not instruct one on how one can interpret difference.
as a bh enthusiast, the discovery was very impressive!
Indeed. Thanks for writing, man. ✌
Allah hu Akbar
So basically star come through get some matter and leave with there twin
Will Gravity Plus catch The Perseids? It's my favorite primetime show. If not, I'll probably go for Hulu instead.
Maybe we shouldn't give scientific instruments the same name as basic forces of Nature ( "gravity", "Gravity" and "Gravity +" are all a bit confusing - why not juat call them all Beyoncé ? )
I know right!? Scientists suck at names.
That second smaller type face number they throw up @ the 4:42 mark 5430 KPS should be MPS miles per second, that's the conversion, that's a typo. So if you multiply 5430 MPS by 3600 it's 19,548,000 MPH nineteen million five hundred forty eight thousand miles per hour. pretty fast.
😅😅😅😅😅😅well information good show you 😅😅😅
Question. What black hole does a tornado rotate around.😂
I remain a black hole skeptic. In extreme gravity why could, would there not be new physics. Inference is inference only. Observation is gold.
The physics of "extreme gravity" is described by general relativity. Why do you think we need _another_ theory for extreme gravity?
Why do people continually ignore the asterisk as though it doesn't exist? It's called Sagittarius A* (A-star), not Sagittarius A. C'mon people!
I know right!?
I thought it was Sagittarius A* - pronounced A star
How deadly it would be to exist on a planet orbiting one of these stars! We wouldn't!
Actually we see them moving so fast but for them time is slowed down and they’re moving/experiencing time at ‘normal’ speeds, but the rest of the galaxy is almost frozen in time. Just think about it
@@precursors The speed isn't the concern. It's the sheet proximity to the black hole that would make conditions inhospitable. The radiation from it would be fatal.
@@upscaleavenue Concern? Who said anything about habitability? We're talking about time and speed here. These stars get so close to the blackhole and move so fast that time passes too little for them and too fast for us, from their perspective.
I suppose this star will also suffer some time dilation. So we might observe it's orbit being skewed in spacetime.
Also, the plane of those orbits are not perpendicular to our line of sight.
Putting those together, you got some horrible calculations, to define those orbits, not to mention red shift so close to a smbh.
Pretty impressive, if they have done those correctly.
But bro why it's path will get skewed even if it is moving at that speed
@@ankitjr.6037 Because it is said that this one star is moving at 8% the speed of light.
At those speeds, it will suffer from a bit of time dilation.
That's where Newtonian physics breaks down and the star will no longer describe the usual type of elliptical orbit that occurs at a lower speed. Let alone, the effects near a smbh. Therefore I figured, I say I am impressed, because I imagine, it takes quite some calculations to figure it out.
@@wernerboden239 ohh that's what👉👉
@@ankitjr.6037 Yup. At least you are one of those people who can simply ask questions like a normal human being, rather than some, who need to redo kindergarten.
@@ankitjr.6037 WHEN TIME DILATES SPACE CONTRACTS. REMEMBER SPACE AND TIME make up the fabric of universe together. Not time alone.
I like this video its interestyng

AMAZING to just think that is possible to happen
😌❤
Which star is moving at 8% light speed? Was it referenced in the video?
The star that is moving 8% the speed of light is S4714. Not mentioned in the video specifically other than at 1:25 where they mention five new stars S4711 to S4715. Later a star (S29) travelling at 8740km/s is mentioned as the record holder. But that is only 2.9% the speed of light. An obvious error in the video.
Бог это Время, Гравитация творит чудеса в Чёрной Энергии!
this brought me a question,
imagine this,
2 objects going at each other 60% light speed, if you were to say one of the objects was your eye,
what would you see?
-an object going to you at 120% lightspeed “from your prospective”
-or something that was 60% lightspeed-distance as it was before?
-or it’ll be invisible because light cant be faster.
if, you can see it at 120% speed of light, will you be seeing the future?
Take an example, you are 500 million light years away from earth, now you’re seeing the dinosaurs.
so, if you were traveling away from earth at light speed exact, the earth is stopped in time.
but what if you were going towards earth faster than light?
is the calculation reversed and you see the future.
hmm what about negative velocity lol
probably only in the 4th dimension idek
Would be cool if that fastest star had planets with a civilization on it there time would be so cool.
Crazy.
