Watch Stars Move Crazy Fast Around Supermassive Black Hole
HTML-код
- Опубликовано: 21 сен 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.
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.
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
This channel is going to explode! Superb editing.
Oh, that's really great to hear. Thanks for these words of motivation. I appreciate 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!
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.
@@medexamtoolscom Right. It's possible that S29 was at one time the fastest star detected. Then later a star travelling at 8% of c was discovered. Then made the assumption that the two were one and the same star.
They need to fact check their own videos before uploading.
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
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! ❤
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!
It’s incredible how black holes can toss supermassive objects like they’re nothing
Crazy.
Because they have mass more than those objects
Imagine someone from other galaxy say this galaxy black hole is really mysterious
Crazy.
3:19
This footage is awesome
Makes me wonder if being on a planet going 8% the speed of light would feel different than going 67k mph on ours
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 !
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
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!
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.
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.
Imagine if we could get an observatory array like this on the moon
That will happen sooner than we think.
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.
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
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.
Just subscribed just now. Great video. Can’t wait to see more in the future.
at that speed it could orbit earth once every ~4 seconds
Crazy right!?
as a bh enthusiast, the discovery was very impressive!
Indeed. Thanks for writing, man. ✌
Nassim Herrimein explains black holes better than anyone else. He's working on a unified theory of physics
❤
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.
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
Gravity will be replaced by gravity plus later this year sounds funny out of context.
Wow!
I hope none of these stars have planets with life
Thumbnail of the year 😍✌🏼
Yayy!!! Thank you! 😍
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.
What a total madness. You saw that “orbit of neptune” image?? Unbelievable
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
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.
Galaxy center is always impressive
And intense. ✌
There is an error in the black hole animation. You have an accretion disk rotating simultaneously in opposite directions
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?
"petrifying bottomless hole"... what a line... This vid started our Christmas party this year.. I played it for us all at the start and it was a big hit.. Started a big conversation.. Now I need to pop back and get into it.. thanks brother.. Merry Christmas to all of you..
Haha, Merry Christmas big brother. All the best to you and your family. ✌
Hopefully JWST will give us more detail views.
That telescope has so much to give.
Astrophysicist Andrea Ghez did this year's ago in 2000. It was on How The Universe Works.
I take it that these stars have no planets surrounding them. Since they’re being flung out with incredibly ludicrous force and speeds 💫
Whats fascinating to think is that out of all the galaxies out there, this is just one of the stars out of many that could be orbiting black holes maybe with near light speed. Improbable but with how much we know it's possible. 😯
Thank you!!! 😌
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.
I hope they're going to put JWST's eyes toward this magnificence.
Indeed, they will at some point.
Sun to the black hole: oooooh oooh oooh you set my soul alight! 😂
😄😄
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.
❤
The black hole accretion disc animation at 5:00 is completely wrong. Tsk. Tsk.
Thanks, i thought so
Or, since there is no "bending of space and time" perhaps it's orbiting a plasmoid.
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.
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!?
"That's No Supermassive Black Hole. It's a Space Station."
😄
This same effect happens in beehive clusters. Beehive clusters are star forming regions.
The stars and binaries that orbit each other in these situations do not follow any Newtonian, or General Relativity models of gravity.
There are many papers on this type of observation. The conclusion is that there must be a substantial EM force at play here, like they are orbiting in a ring current, around a plasmoid focal point, rather than following any known models of gravity. Just like a galaxy does not follow Newtonian gravity, or GR, it appears that beehives also have a substantial EM force at play as well.
A supermassive blackhole and the stars in its vicinity are like when we stir a liquid in our cup. The closer to the middle, the faster the "objects" move. Massive objects like stars moving at the intensely high speed like that is so terrifying to imagine! 🤯😱
It's crazy right!?
@@Cosmoknowledge Yes it is! 🤯
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?
Imagine planets orbiting these stars moving around the black hole at the center of our galaxy.
Every decade or so, they'll have the best view in the galaxy. Sgr A* and its accretion disk probably looks like as bright as the sun does to us.
Imagine that you are living in those mysterious object what do you feel 😢
This is such a great video!
So awesome to hear that. Thank you! ❤
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.
Mind bending... 🤪
Another great video 👍👍👍
Great! Thank you, my friend! 😌❤
Somewhere far away aliens are laughing to our conclusions...
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
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.
I find it hard to believe the gravity of this black hole, the size of a grain of sand in comparison to the galaxy, is holding our sun in orbit over tens of thousands of lightyears away.
When it comes to black holes, size doesn't matter. Mass matters.
@@Cosmoknowledge bro size does matter 😂
@@agsolarpower5975 no.it does not. If we replace our sun with a coin size black hole with the same mass as sun , our planets would revolve around it as same as they revolve around sun.
man I can't wait to get out interstellar so we can start making stellar clockwork with these
😄
U know the shit is real when 90 billion kms are "so close"
Exactly. 😄
Will the orbits decay enough that Sagittarius will swallow those stars or they will collide?
Eventually, probably.
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.
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?
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. 😄
dont forget that u are currently observing its light.. that maybe distorted by black holes
It can, if close enough.
What kind of G’s would you feel as you swung around a massive black hole 8% light speed?
Wao esto si vale aunque esté en inglés
Aprendo de paso
I'm so curious about what JWST gonna find regarding these kind of phenomenon. 🤔
It's gonna blow our minds away.
I’m curious, 8740km/s is about 2.9% the speed of light. Where did the 8% measurement come from?
wie gross ist Sagittarius A heute das licht bis zur erde benötigt paar milliarden jahre?
It seems that the simulation of the black hole is incorrect, where the rotations of the front half accretion disk and the warped back half are opposite to each other instead of making up a loop.
I absolutely love her voice.
So great to hear that. Thank you! 😌❤
Assuming that planets directly orbiting the super massive black hole, how is time affected on these planets comparing to that on our earth????
If a black hole the mass of the Sun was put at the center of our solar system, planets would orbit just as they do around the Sun, however there would be no light.
somthing is not right here if there is a black hole why those stars not fall inside ? it could be simply mass centre
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..
Like i was watching an ATOM, but a giant one !
Indeed. The resemblance between vastness and the quantum world is crazy.
🇨🇱 Shout out to Chile for all the telescope sites 🇨🇱
black holes in expaction: eats stars
relaity: swing stars around
😄
The terrifying part is that Sagittarius the black hole, is moving our entire galaxy towards another bigger black hole, "the great attractor"
No, the black hole is not moving us toward the Great Attractor. The Great Attractor is the gravitational center of the Laniakea Supercluster, and all galaxies in this supercluster are moving toward the Great Attractor.
I wonder if they're loosing their mass every time they have a slingshot around the Black Hole
Not unless they get too close to it.
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! 😌❤
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.*
Would be cool if that fastest star had planets with a civilization on it there time would be so cool.
Crazy.
U watching to much sci Fi dude
@Realist38 so far space has out done Sci fi so will just wait and see.
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.
It appears that inwardly spiralling stars approach the black hole in an equatorial plane even though the galaxy is a three dimensional structure. Why?
Jean Luc Picard waiting there.
I'm very impressed by this very informative video.
Awesome narrator and awesome graphics
So great to hear that. Thank you so much! ❤
still not as fast as the speed of post nut clarity hitting the brain
😄😄😄❤
It's actually called Sagittarius A star. The asterisk * is part of its name.
Yes, that's correct. It's so hard for me to add the star sometimes.
Really cool! I just love black holes.
They are fascinating objects. Thank you!
From far far away
All I'm fairly sure of is 'acid' has nothing on this stuff, and I go back a bit.
😄
I believe I know how penny feels, on the Big Bang Theory show.
i thought we couldn't see anything in our galaxy's center cause of all the dust that was there
We can penetrate the dust with certain instruments.
